最近项目要用到MyBatis+SpringMVC+Spring，所以刚刚试着整合个测试项目，在此记录一下。如有疏漏之处，还请诸位前辈提点一二。
如果对SpringMVC还不太了解的朋友，可以看我之前的日志，这里是连接——http://blog.csdn.net/baimusensen/article/details/16120429
1.导jar包
注：因为能力有限，我这里的jar包有些jar包可能多余，不过都导进来肯定能跑起项目来
2.修改web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>
<servlet-name>spring3mvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!-- 如果不写这个init标签及其内容，那么SpringMVC的相关配置就要写在
与<servlet-name>中的内容一致的xml里 -->
<init-param>
<param-name>contextConfigLocation</param-name>
<!-- 这里是配置文件的路径 -->
<param-value>classpath*:/applicationContext.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>spring3mvc</servlet-name>
<!-- url-pattern里的内容的意思代表：告诉程序什么样格式的url地址才能算是action，
并往action里走。对于我这里写的*.action的话，当我输入类似于findAll.action
这样的url时，才会让程序开始寻找相应的action -->
<url-pattern>*.action</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
3.添加applicationContext.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:p="http://www.springframework.org/schema/p"
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-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
<!-- 引入jdbc配置文件 -->
<context:property-placeholder location="classpath:dataSource.properties" />
<!--创建jdbc数据源 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${driver}" />
<property name="url" value="${url}" />
<property name="username" value="${username}" />
<property name="password" value="${password}" />
</bean>
<!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
<!-- 创建SqlSessionFactory，同时指定数据源 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="configLocation" value="classpath:mybatis-config.xml"></property>
<property name="dataSource" ref="dataSource" />
</bean>
<!-- 扫描com这个包里的所有类，把里面配上相应注解的类全都放在容器中进行管理 -->
<context:component-scan base-package="com"/>
<!-- 添加注解驱动 -->
<mvc:annotation-driven />
<!-- 定义跳转的文件的前后缀 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个
可用的url地址 -->
<property name="prefix" value="/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<!-- Mapper接口所在包名，Spring会自动查找其下的Mapper -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.mapper"/>
</bean>
<bean id="lalaMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
<property name="mapperInterface" value="com.mapper.ILalaMapper"/>
<property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
</bean>
</beans>
4.添加mybatis-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTDConfig 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<!-- mybatis的数据类型和处理器等等...都可以实现接口重写，然后配置 -->
<configuration>
<mappers>
<!--映射文件-->
<mapper resource="testMapper.xml"/>
</mappers>
</configuration>
5.添加配置文件——dataSource.properties
driver=oracle.jdbc.driver.OracleDriver url=jdbc\:oracle\:thin\:@Kewpie-HP\:1521\:KEWPIE username=Kewpie password=qyj890721
6.添加MyBatis映射文件——testMapper.xml
这个xml的名字随便起，只要最后与mybatis-config.xml里的文件名对应上就可以了
<?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.mapper.ILalaMapper"> <select id="selectAllLala" resultMap="LalaMapper"> select * from TEST13X11X19X1 </select> <resultMap type="com.model.Lala" id="LalaMapper" autoMapping="true"> <id property="id" column="t_id"/> <result property="name" column="t_name"/> </resultMap> </mapper>
7.写JavaBean
public class Lala implements Serializable {
private int id;
private String name;
//getter、setter省略
}
8.写接口——ILalaMapper
注：这里这个ILalaMapper就相当于其他地方的UserDao之类的，我这个名字是随便起的
package com.mapper;
import java.util.List;
import com.model.Lala;
public interface ILalaMapper {
List<Lala> selectAllLala();
}
9.写service接口及其实现类
service接口
package com.service;
import java.util.List;
import com.model.Lala;
public interface ITestService {
List<Lala> findAll();
}
实现类
package com.service.impl;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Service;
import com.mapper.ILalaMapper;
import com.model.Lala;
import com.service.ITestService;
@Service("testService")
public class TestServiceImpl implements ITestService {
@Resource
private ILalaMapper lalaMapper;
public List<Lala> findAll() {
return this.lalaMapper.selectAllLala();
}
}
10.写Controller层
package com.controller;
import java.util.List;
import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.model.Lala;
import com.service.ITestService;
@Controller
@RequestMapping("testBase")
public class TestController {
@Resource
private ITestService testService;
@RequestMapping("testA")
public String test(){
System.out.println("进Action了");
List<Lala> list=this.testService.findAll();
for(Lala l:list){
System.out.println("id->"+l.getId()+",name->"+l.getName());
}
return "success";
}
}
都写好之后，启动tomcat，在地址栏中输入地址——http://localhost:8080/myeclipse_mybatis_springmvc_test/testBase/testA.action
结果在控制台输入的内容如下
至此，MyBatis+SpringMVC+Spring最简单的整合项目完成
