前言：
　　该代码适用于与spring框架整合的项目
　　代码：
　　dao层的junit测试父类
　　junitDaoBase.java
package cn.firstflag.crm.dao;
import javax.annotation.Resource;
import javax.sql.DataSource;
import org.apache.log4j.Logger;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractTransactionalJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import cn.firstflag.crm.controller.BaseController;
/**
* @Description junit DAO层父类
* @Author zhanmin.zheng
* @CreateDate 2016/01/1
* @ModifyDate
* @Version 1.0
*/
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:root-context.xml"，"classpath:mvc-context.xml"})//spring配置文件全部加入
public class JUnitDaoBase extends AbstractTransactionalJUnit4SpringContextTests {
protected Logger log = Logger.getLogger(BaseController.class);//log4j
@Override
@Resource(name = "dataSource")
public void setDataSource(DataSource dataSource) {
super.setDataSource(dataSource);
}
}
　　service层的junit测试父类
　　junitServiceBase.java
package cn.firstflag.crm.service;
import org.apache.log4j.Logger;
import org.junit.Before;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import cn.firstflag.crm.controller.BaseController;
/*
* @ClassName Service测试类父类
* @Author zhanmin.zheng
* @CreateDate 2016/02/16
* @Version 1.0
*/
public class JunitServiceBase {
protected Logger log = Logger.getLogger(BaseController.class);//log4j
protected ApplicationContext context;//应用上下文
public JunitServiceBase() {
context = new ClassPathXmlApplicationContext(new String[]{
"classpath:root-context.xml"，"classpath:mvc-context.xml"});
}
}
　　controller层的junit测试父类
　　需要在spring配置中注入两个bean
<bean
class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/>
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
