Spring+SringMVC+Mybatis整合（idea版本，Maven管理项目）
前言：最近刚把SSM框架过了一遍，为了防止忘记配置，特意记录一下SSM整合的过程
搭建环境以及版本介绍
本人采用的是idea2017，Maven3.6.1，Spring 5.1.6.RELEASE，Mybatis 3.5.0
创建JavaWeb项目
创建后的目录结构如下
引入依赖
pom.xml文件如下，有点多，但是里面的东西确实比较好用，推荐使用

配置文件
这里我使用mybatis-generator这个插件来生成*Mapper.xml文件，对于一般的CURD基本上是都包括了，强烈推荐
generatorConfig.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
<!--你的数据库驱动位置-->
<classPathEntry
location="D:/Maven/localRepository/mysql/mysql-connector-java/8.0.15/mysql-connector-java-8.0.15.jar"/>
<context id="mysqlgenerator" targetRuntime="MyBatis3">
<!--不生成注释-->
<commentGenerator>
<property name="suppressAllComments" value="true"/>
</commentGenerator>
<!-- 配置数据库连接 -->
<jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/mybatis?serverTimezone=GMT"
userId="root"
password="你的密码"/>
<!-- 指定javaBean生成的位置 -->
<javaModelGenerator targetPackage="cn.kt.domain" targetProject="src/main/java">
<!-- 在targetPackage的基础上，根据数据库的schema再生成一层package，最终生成的类放在这个package下，默认为false -->
<property name="enableSubPackages" value="true"/>
<!-- 设置是否在getter方法中，对String类型字段调用trim()方法 -->
<property name="trimStrings" value="true"/>
</javaModelGenerator>
<!--指定sql映射文件生成的位置 -->
<sqlMapGenerator targetPackage="cn.kt.mapper" targetProject="src/main/resources">
<property name="enableSubPackages" value="true"/>
</sqlMapGenerator>
<!-- 指定dao接口生成的位置，mapper接口 -->
<javaClientGenerator type="XMLMAPPER" targetPackage="cn.kt.mapper" targetProject="src/main/java">
<property name="enableSubPackages" value="true"/>
</javaClientGenerator>
<!-- table表生成对应的DoaminObject -->
<table tableName="student" domainObjectName="Student"/>
</context>
</generatorConfiguration>
复制代码
配置完成后 启动插件：打开maven->Plugins->mybatis-generator,直接运行就可以里
applicationContext-mybatis.xml 直接将扫描mapper.xml的任务交给spring，便不在这里配置 成功后生成四个文件
特别说明StudentExample这个类是为了实现QBC（query by criteria）查询
db.properties 数据库相关的属性配置，记得在url后添加serverTimezone的设置
driver=com.mysql.cj.jdbc.Driver url=jdbc:mysql://localhost:3306/mybatis?serverTimezone=GMT%2B8&useSSL=false name=root password=你的密码 maxActive=100 maxIdle=50 initialSize=20 timeBetweenEvictionRunsMillis=60000 minEvictableIdleTimeMillis=300000 复制代码

ehcacahe.xml 如果没有在mybatis配置文件中启用ehcache可以不用配置
<?xml version="1.0" encoding="UTF-8"?>
<ehcache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://ehcache.org/ehcache.xsd">

eternal="false"
overflowToDisk="true"
timeToIdleSeconds="120"
timeToLiveSeconds="120"
diskExpiryThreadIntervalSeconds="120"
memoryStoreEvictionPolicy="LRU">
</defaultCache>
</ehcache>
复制代码
log4j.properties,同样如果没有启用也不用配置
### 设置### log4j.rootLogger = ERROR ,stdout log4j.logger.cn.kt.mapper=TRACE log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n 复制代码
至此，SSM的配置文件就算写完了
最后记得把maven引入的依赖倒入war包，不然运行起来会报ClassNotFound的bug
测试
编写一个controller
@Controller
public class MyController {
@Autowired
private MyService myService;
@RequestMapping("/test")
public ModelAndView controller(){
myService.service();
ModelAndView modelAndView=new ModelAndView();
modelAndView.setViewName("hello");
return modelAndView;
}
}
复制代码
一个service
@Service
public class MyService {
@Autowired
StudentMapper studentMapper;
public void service(){
StudentExample studentExample=new StudentExample();
StudentExample.Criteria criteria1 = studentExample.createCriteria();
criteria1.andAgeBetween(1,10);
List<Student> list=studentMapper.selectByExample(studentExample);
System.out.println(list);
}
}
复制代码
在地址栏输入相应的路径， http://localhost:8080/项目名/test service层成功查询到了数据，在控制台输出
浏览器也成功跳转至相应的页面
