这篇文章主要讲解使用 Eclipse 对Spirng+SpringMVC+Maven+Mybatis+MySQL项目搭建过程,包括里面步骤和里面的配置文件如何配置等等都会详细说明。
如果还没有搭建好环境(主要是Maven+MySQL的配置)的猿友可以参考博主以前的一篇文章:
http://blog.csdn.net/u013142781/article/details/50300233接下来马上进入项目搭建过程:
CREATE TABLE `t_user` ( `USER_ID` int(11) NOT NULL AUTO_INCREMENT, `USER_NAME` char(30) NOT NULL, `USER_PASSWORD` char(10) NOT NULL, PRIMARY KEY (`USER_ID`), KEY `IDX_NAME` (`USER_NAME`) ) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (1, 'luoguohui', '123456'); INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (2, 'zhangsan', '123456');
4、输出项目名,包(Packaging,如果只是普通的项目,选jar就好了,如果是web项目就选war,这里是web项目,所以选择war)
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.luo</groupId> <artifactId>first_maven_project</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <!-- spring版本号 --> <spring.version>3.2.8.RELEASE</spring.version> <!-- log4j日志文件管理包版本 --> <slf4j.version>1.6.6</slf4j.version> <log4j.version>1.2.12</log4j.version> <!-- junit版本号 --> <junit.version>4.10</junit.version> <!-- mybatis版本号 --> <mybatis.version>3.2.1</mybatis.version> </properties> <dependencies> <!-- 添加Spring依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <!--单元测试依赖 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junit.version}</version> <scope>test</scope> </dependency> <!-- 日志文件管理包 --> <!-- log start --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>${log4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>${slf4j.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- log end --> <!--spring单元测试依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> <!--mybatis依赖 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.0</version> </dependency> <!-- mysql驱动包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> </dependencies> </project>
7.1、mybatis包下添加mybatis-config.xml文件(mybatis配置文件):
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> </configuration>
7.2、properties包下添加jdbc.properties文件(数据源配置文件):
jdbc_driverClassName=com.mysql.jdbc.Driver jdbc_url=jdbc:mysql://localhost:3306/luo jdbc_username=root jdbc_password=root
7.3、mapper包下userMapper.xml配置文件(表映射文件):
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.luo.dao.UserDao"> <!--设置domain类和数据库中表的字段一一对应,注意数据库字段和domain类中的字段名称不致,此处一定要!--> <resultMap id="BaseResultMap" type="com.luo.domain.User"> <id column="USER_ID" property="userId" jdbcType="INTEGER" /> <result column="USER_NAME" property="userName" jdbcType="CHAR" /> <result column="USER_PASSWORD" property="userPassword" jdbcType="CHAR" /> </resultMap> <!-- 查询单条记录 --> <select id="selectUserById" parameterType="int" resultMap="BaseResultMap"> SELECT * FROM t_user WHERE USER_ID = #{userId} </select> </mapper>
7.4、spring配置文件application.xml:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd"> <!-- 引入jdbc配置文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="locations"> <list> <value>classpath:properties/*.properties</value> <!--要是有多个配置文件,只需在这里继续添加即可 --> </list> </property> </bean> <!-- 配置数据源 --> <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> <!-- 不使用properties来配置 --> <!-- <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://localhost:3306/learning" /> <property name="username" value="root" /> <property name="password" value="christmas258@" /> --> <!-- 使用properties来配置 --> <property name="driverClassName"> <value>${jdbc_driverClassName}</value> </property> <property name="url"> <value>${jdbc_url}</value> </property> <property name="username"> <value>${jdbc_username}</value> </property> <property name="password"> <value>${jdbc_password}</value> </property> </bean> <!-- 自动扫描了所有的XxxxMapper.xml对应的mapper接口文件,这样就不用一个一个手动配置Mpper的映射了,只要Mapper接口类和Mapper映射文件对应起来就可以了。 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.luo.dao" /> </bean> <!-- 配置Mybatis的文件 ,mapperLocations配置**Mapper.xml文件位置,configLocation配置mybatis-config文件位置--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="mapperLocations" value="classpath:mapper/*.xml"/> <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" /> <!-- <property name="typeAliasesPackage" value="com.tiantian.ckeditor.model" /> --> </bean> <!-- 自动扫描注解的bean --> <context:component-scan base-package="com.luo.service" /> </beans>
8.1、com.luo.domain下添加User.Java文件:
package com.luo.domain; public class User { private Integer userId; private String userName; private String userPassword; public Integer getUserId() { return userId; } public void setUserId(Integer userId) { this.userId = userId; } public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getUserPassword() { return userPassword; } public void setUserPassword(String userPassword) { this.userPassword = userPassword; } }
8.2、com.luo.dao下添加UserDao.java文件:
package com.luo.dao; import com.luo.domain.User; public interface UserDao { /** * @param userId * @return User */ public User selectUserById(Integer userId); }
8.3、com.luo.service下添加UserService.java接口和UserServiceImpl实现类:
package com.luo.service; import com.luo.domain.User; public interface UserService { User selectUserById(Integer userId); }
package com.luo.service; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import com.luo.dao.UserDao; import com.luo.domain.User; @Service public class UserServiceImpl implements UserService { @Autowired private UserDao userDao; public User selectUserById(Integer userId) { return userDao.selectUserById(userId); } }
9.1、com.luo.baseTest下添加SpringTestCase.java:
package com.luo.baseTest; import org.junit.runner.RunWith; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; //指定bean注入的配置文件 @ContextConfiguration(locations = { "classpath:application.xml" }) //使用标准的JUnit @RunWith注释来告诉JUnit使用Spring TestRunner @RunWith(SpringJUnit4ClassRunner.class) public class SpringTestCase extends AbstractJUnit4SpringContextTests { }
9.2、com.luo.service添加UserServiceTest.java:
package com.luo.service; import org.junit.Test; import org.springframework.beans.factory.annotation.Autowired; import com.luo.baseTest.SpringTestCase; import com.luo.domain.User; public class UserServiceTest extends SpringTestCase { @Autowired private UserService userService; @Test public void selectUserByIdTest(){ User user = userService.selectUserById(1); System.out.println(user.getUserName() + ":" + user.getUserPassword()); } }
9.3、运行单元测试,UserServiceTest右键Run As –>Junit Test,运行结果:
下面加入springmvc,并转换maven工程为web项目
如果上面webapp为空的,说明这个项目还不是web项目:
接下来打开如下页面。将红框里面的勾去掉,确定(OK):
然后重新打开刚刚那个页面,把Dynamic web Module勾上,就会看到红框的内容,点击:
然后配置如下:
那么webapp下就会生成这些东西:
11.1、pom.xml文件添加依赖,修改后配置如下:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.luo</groupId> <artifactId>first_maven_project</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <properties> <!-- spring版本号 --> <spring.version>3.2.8.RELEASE</spring.version> <!-- junit版本号 --> <junit.version>4.10</junit.version> <!-- mybatis版本号 --> <mybatis.version>3.2.1</mybatis.version> </properties> <dependencies> <!-- 添加Spring依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <!--单元测试依赖 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>${junit.version}</version> <scope>test</scope> </dependency> <!--spring单元测试依赖 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> <!--mybatis依赖 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <!-- mybatis/spring包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.0</version> </dependency> <!-- mysql驱动包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.29</version> </dependency> <!-- javaee-api包 注意和项目使用的JDK版本对应 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency> <!-- javaee-web-api包 注意和项目使用的JDK版本对应 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-web-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency> </dependencies> </project>
其实也就增加了下面两个
<!-- javaee-api包 注意和项目使用的JDK版本对应 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency> <!-- javaee-web-api包 注意和项目使用的JDK版本对应 --> <dependency> <groupId>javax</groupId> <artifactId>javaee-web-api</artifactId> <version>6.0</version> <scope>provided</scope> </dependency>
11.2、在src/main/resource中添加springmvc文件夹,然后添加文件spring-mvc.xml,内容如下:
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd"> <mvc:annotation-driven /> <!-- 扫描controller(controller层注入) --> <context:component-scan base-package="com.luo.controller"/> <!-- 对模型视图添加前后缀 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/view/" p:suffix=".jsp"/> </beans>
11.3、配置web.xml
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5"> <display-name>Archetype Created Web Application</display-name> <!-- 起始欢迎界面 --> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 读取spring配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:application.xml</param-value> </context-param> <!-- 设计路径变量值 --> <context-param> <param-name>webAppRootKey</param-name> <param-value>springmvc.root</param-value> </context-param> <!-- Spring字符集过滤器 --> <filter> <filter-name>SpringEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <filter-mapping> <filter-name>SpringEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- springMVC核心配置 --> <servlet> <servlet-name>dispatcherServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <!--spingMVC的配置路径 --> <param-value>classpath:springmvc/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <!-- 拦截设置 --> <servlet-mapping> <servlet-name>dispatcherServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 错误跳转页面 --> <error-page> <!-- 路径不正确 --> <error-code>404</error-code> <location>/WEB-INF/errorpage/404.jsp</location> </error-page> <error-page> <!-- 没有访问权限,访问被禁止 --> <error-code>405</error-code> <location>/WEB-INF/errorpage/405.jsp</location> </error-page> <error-page> <!-- 内部错误 --> <error-code>500</error-code> <location>/WEB-INF/errorpage/500.jsp</location> </error-page> </web-app>
11.4、添加index.jsp,在src/main/webapp/WEB-INF下新建一个文件夹view,添加一个index.jsp,内容如下:
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <html> <body> <h2>Hello World!</h2> 用户名: ${user.userName}<br> 密码:${user.userPassword}<br> </body> </html>
11.5、写controller
在src/main/java下新建一个包com.luo.controller.然后新建一个类UserController.java,其内容如下
package com.luo.controller; import javax.annotation.Resource; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; import com.luo.domain.User; import com.luo.service.UserService; @Controller public class UserController { @Resource private UserService userService; @RequestMapping("/") public ModelAndView getIndex(){ ModelAndView mav = new ModelAndView("index"); User user = userService.selectUserById(1); mav.addObject("user", user); return mav; } }
11.6 运行!!!!完成!

之前有个兄弟按照我的配置,但是发现pom.xml文件报如下错误:
Cannot detect Web Project version. Please specify version of Web Project through <version> configuration property of war plugin. E.g.: <plugin> <artifactId>maven-war-plugin</artifactId> <configuration> <version>3.0<ersion> </configuration> </plugin>
解决方案是,如下的三个地方jdk版本需要保持一致:
1、项目右键->属性->Java Compiler:
2、项目右键->属性->Project Facets:
3、如果pom.xml配置了如下的插件的话:
<build> <plugins> <plugin> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.7</source> <target>1.7</target> </configuration> </plugin> <plugin> <artifactId>maven-war-plugin</artifactId> <version>2.4</version> <configuration> <version>3.0</version> </configuration> </plugin> </plugins> <finalName>webserver</finalName> </build>
这里也要跟上面两个保持一致:
