自从进入一家游戏公司以后,就抛弃了eclipse转战于idea,刚开始一直很不习惯,但是用了一周以后,在打开eclipse的时候,有一种想卸载掉的冲动,好吧,我是觉得idea比eclipse好用,关于它们的战争我们就不讨论了,下面介绍一下idea中怎么搭建ssm基于maven的整合框架吧。
作为一个优秀的框架,spring一直横穿整合javaee的世界,在学习javaweb的时候,由原来的servlet学习到spring框架,整个过程的时间大概也有2年了吧,在学校的时候,一直使用ssh(Struts2)这个框架。后来接触springmvc,springboot等,我还是喜欢spring的产品的。尽管它有那么点难懂,
在idea中首先我们建立一个maven项目
如图next->写上项目名
继续下一步
这个地方一定要添加一个 archetypeversion=release
创建完项目后创建对应的文件夹
源码路径,资源路径,webapp路径等如图所示
创建完相应 的文件夹后然后点击右上角
打开之后选择 modules添加spring,web等
然后在添加war包,将项目打包成war。
到此,有关界面上的操作就是这样了,然后来看整合文件了。
首先我们在resources文件加下创建一个spring子文件夹用于添加配置 如图所示
在这里首先把jar引进来,由于项目是通过maven管理的,所以只要添加pom文件就可以了。
pom.xml

然后再是添加spring配置文件
正如上图所示:第一个文件
applicationContext.xml

通过这种方式命名的话可以统一进行管理和进入到web.xml中。
jdbc配置文件
jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://127.0.0.1:3306/twjitm?useUnicode=true&characterEncoding=utf-8 jdbc.username=root jdbc.password=123456 #最大连接数 c3p0.maxPoolSize=30000 #最小连接数 c3p0.minPoolSize=10 #关闭连接后不自动commit c3p0.autoCommitOnClose=false #获取连接超时时间 c3p0.checkoutTimeout=10000 #当获取连接失败重试次数 c3p0.acquireRetryAttempts=2
redis.properties
redis.host=127.0.0.1 redis.port=6379 redis.pass=xx redis.maxIdle=300 redis.testOnBorrow=true
最后就是关于web.xml的配置了,如下所示
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <welcome-file-list> <welcome-file>jsp/index.jsp</welcome-file> </welcome-file-list> <servlet> <servlet-name>SpringMVC</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext*.xml</param-value> <!-- <param-value>classpath:bean/applicationContext.xml</param-value>--> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported> </servlet> <servlet-mapping> <servlet-name>SpringMVC</servlet-name> <url-pattern>*.do</url-pattern> </servlet-mapping> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext*.xml</param-value> </context-param> <!-- 编码过滤器 --> <filter> <filter-name>encodingFilter</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> </filter> <filter-mapping> <filter-name>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- spring监听器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止spring内存溢出监听器,比如quartz --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <session-config> <session-timeout>30</session-timeout> </session-config> </web-app>
到这整合搭建到是完成了,我们编写一个测试类进行测试
在数据库中执行sql脚本:
CREATE TABLE `user` ( `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '用户ID', `email` varchar(255) NOT NULL COMMENT '用户邮箱', `password` varchar(255) NOT NULL COMMENT '用户密码', `username` varchar(255) NOT NULL COMMENT '用户昵称', `role` varchar(255) NOT NULL COMMENT '用户身份', `status` int(1) NOT NULL COMMENT '用户状态', `regTime` datetime NOT NULL COMMENT '注册时间', `regIp` varchar(255) NOT NULL COMMENT '注册IP', PRIMARY KEY (`id`), UNIQUE KEY `email` (`email`) USING BTREE ) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8; INSERT INTO `user` VALUES ('1', 'xxx', 'xxxxx', 'xxxxx', 'root', '0', '2017-03-28 09:40:31', '127.0.0.1'); SET FOREIGN_KEY_CHECKS=1;
获得一张表,然后编写mapper映射文件
user.xml
<?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"> <!-- 设置为IUserDao接口方法提供sql语句配置 --> <mapper namespace="com.twjitm.user.dao.IUserDao"> <resultMap id="userList" type="com.twjitm.user.entity.User"> <id column="id" property="id" ></id> <id column="email" property="email" ></id> <id column="password" property="password" ></id> <id column="username" property="username" ></id> <id column="role" property="role" ></id> <id column="status" property="status" ></id> <id column="regTime" property="regTime" ></id> <id column="regIp" property="regIp" ></id> </resultMap> <select id="getAllUser" resultMap="userList"> SELECT * FROM user </select> </mapper>
再dao中创建一个方法,如代码所示
package com.twjitm.user.dao; import com.twjitm.user.entity.User; import org.springframework.stereotype.Repository; import java.util.List; /** * Created by Administrator on 2017/8/26. */ @Repository public interface IUserDao { public List<User> getAllUser(); }
注意这个地方和ssh不一样的是,dao中只有接口的定义,没有实现。在接口上添加repository注解。
然后添加service层,如代码所示
package com.twjitm.user.service; import com.twjitm.user.entity.User; import java.util.List; /** * Created by twjitm on 2017/8/26. */ public interface IUserService { public List<User> getUser(); }
实现类
package com.twjitm.user.service.Impl; import com.twjitm.user.dao.IUserDao; import com.twjitm.user.entity.User; import com.twjitm.user.service.IUserService; import org.springframework.stereotype.Service; import javax.annotation.Resource; import java.util.List; /** * Created by Administrator on 2017/8/26. */ @Service("userService") public class UserServiceImpl implements IUserService{ @Resource private IUserDao userDao; public List<User> getUser() { return userDao.getAllUser(); } }
然后写一个controller了,如图所示
UserController.java
package com.twjitm.user.controller; import com.twjitm.user.service.IUserService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import javax.annotation.Resource; import java.util.List; /** * Created by Administrator on 2017/8/26. */ @Controller @RequestMapping("/user") public class UserController { @Autowired public IUserService userService; @RequestMapping("info") @ResponseBody public List userInfor(){ System.out.println("----------------------------------------------"); System.out.println( userService.getUser().size()); return userService.getUser(); } }
最后就是发布项目了添加tomcat,点击右上角的小图标
然后点击+ 找到local
然后进行配置,把打好的war包添加到tomcat中
然后运行tomcat,若是看到successful等字样就是运行成功了,
然后在浏览器中运行简单的环境搭建就是这样,各位研究吧
