关于spring mvc+mybatis+junit单元测试

这次测试的目的是直接在单元测试中测试Controller的类。

在单元测试的时候一定要保证spring部分和mybatis部分的代码编写全部正确，即便是没有用到的一些bean和一些mybatis的增删改查。junit会扫描全部的内容，遇到扫描错误的就会报出。

先看applicationContext文件

<?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:mvc="http://www.springframework.org/schema/mvc"xmlns:p="http://www.springframework.org/schema/p" xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsdhttp://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsdhttp://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd"><import resource="classpath:spring/service.xml"/><!-- <context:annotation-config /> --><!-- <context:component-scan base-package="com.ewell.home" use-default-filters="false"><context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/><context:include-filter type="annotation" expression="org.springframework.web.bind.annotation.ControllerAdvice"/></context:component-scan>--><mvc:annotation-driven><mvc:message-converters register-defaults="true"><bean class="org.springframework.flex.http.AmfHttpMessageConverter"/></mvc:message-converters></mvc:annotation-driven> <!-- 使用annotation 自动注册bean, 并保证@Required、@Autowired的属性被注入 --><context:component-scan base-package="com.ewell"><context:exclude-filter type="annotation"expression="org.springframework.stereotype.Controller" /><context:exclude-filter type="annotation"expression="org.springframework.web.bind.annotation.ControllerAdvice" /></context:component-scan><bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"><property name="location" ><value>classpath:datasource.properties</value></property></bean><!-- SqlServer数据源配置 --><bean id="dataSource" class="org.apache.ibatis.datasource.unpooled.UnpooledDataSource"><property name="driver" value="${jdbc-2.proxool.driver-class}" /><property name="url" value="${jdbc-2.proxool.driver-url}" /><property name="username" value="${jdbc-2.user}" /><property name="password" value="${jdbc-2.password}" /></bean><!-- SqlServer配置 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource" /><property name="configLocation" value="classpath:mybatis/mybatis-sqlserver.xml" /><property name="mapperLocations" value="classpath*:com/ewell/home/mapper/*.xml"/></bean><bean id="myBatisDAO" class="com.ewell.isd.mybatis.dao.MyBatisDAO"><property name="sqlSessionFactory" ref="sqlSessionFactory" /></bean><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource" /></bean><bean id="nameMatch" class="org.springframework.transaction.interceptor.NameMatchTransactionAttributeSource"><property name="properties"><props><prop key="*">PROPAGATION_REQUIRED</prop></props></property></bean><bean id="methodCallLogInterceptor" class="com.ewell.isd.spring.interceptor.MethodCallLogInterceptor" /><bean id="transactionInterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor"><property name="transactionManager"><ref local="transactionManager" /></property><property name="transactionAttributeSource"><ref local="nameMatch"/></property></bean><bean id="autoProxyCreator" class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator"><property name="beanNames"><list><value>*Service</value></list></property><property name="interceptorNames"><list><idref local="transactionInterceptor"/> <!-- <idref local="transactionInterceptor_sqlServerL"/> --></list></property></bean><!-- Nothing real usage --><bean id="SpringContextUtil" class="com.ewell.zonghe.configration.SpringContextUtil "/></beans>

mybatis-sqlserver.xml文件

Controller部分：TestController.java

package com.ewell.home.controller;import java.util.HashMap;import java.util.Map;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 com.ewell.home.service.UserService;import com.ewell.home.vo.User;@Controller@RequestMapping("/TestController")public class TestController {@Autowiredprivate UserService userService;@RequestMapping("/getUser")@ResponseBodypublic String getUser(String id){String massage = "";Map<String,Object> map = new HashMap<String,Object>();User user = null;user = userService.getUser(Integer.parseInt(id));if(null == user){massage = "error";}else{massage = "success";}return massage;}}

ServiceImpl文件

package com.ewell.home.service.impl;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;import com.ewell.home.service.UserService;import com.ewell.home.vo.User;import com.ewell.isd.mybatis.dao.MyBatisDAO;@Servicepublic class UserServiceImpl implements UserService{@Autowiredprivate MyBatisDAO myBatisDAO;@Overridepublic User getUser(Integer id) {// TODO Auto-generated method stubreturn (User)myBatisDAO.findForObject("getUser",id);}}

单元测试部分

基类BaseSpringTestCase

package com.ewell;import org.junit.runner.RunWith;import org.springframework.test.context.ContextConfiguration;import org.springframework.transaction.annotation.Transactional;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations={"classpath:applicationContext.xml"})// 添加注释@Transactional 回滚对数据库操作  @Transactionalpublic class BaseSpringTestCase {}

测试类：TestUser

package com.ewell;import static org.junit.Assert.assertEquals;import java.sql.SQLException;import org.junit.Before;import org.junit.Test;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.mock.web.MockHttpServletRequest;import org.springframework.mock.web.MockHttpServletResponse;import com.ewell.home.controller.TestController;import com.ewell.home.service.UserService;import com.ewell.home.vo.User;public class TestUser extends BaseSpringTestCase{private MockHttpServletRequest request;private MockHttpServletResponse response;private UserService userService;@Autowiredprivate TestController testController ;    @Before    public void before(){                                                                   /*        ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"classpath:applicationContext.xml"                ,"classpath:mybatis/mybatis-sqlserver.xml"});*/        request = new MockHttpServletRequest();            request.setCharacterEncoding("UTF-8");            response = new MockHttpServletResponse();    }         @Test    public void addUser(){        User user = new User();String id= "23" ;assertEquals("loginok",testController.getUser(id)) ;    }}
