Junit测试maven+ssm项目的过程及出现的错误总结

junit进行单元测试通常有两种：

package com.puhua.test;

import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;

import com.puhua.model.Users;
import com.puhua.service.UsersService;

public class TestUsersMapper extends AbstractJUnit4SpringContextTests{

private UsersService usersService;

@SuppressWarnings("resource")
@Before
public void before(){

ApplicationContext context = new ClassPathXmlApplicationContext(new String []{"classpath*/spring-mybatis.xml","classpath*:/spring-mvc.xml"});
System.out.println("_________________________");
usersService = (UsersService) context.getBean("usersServiceImpl");
}

@Test
public void testSelectByPrimaryKey(){
Long id = new Long(1);
Users user = usersService.selectByPrimaryKey(id);
System.out.println(user);
}
}

package com.puhua.test;

import javax.annotation.Resource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.web.WebAppConfiguration;

import com.puhua.model.Users;
import com.puhua.service.UsersService;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath*:/spring-mybatis.xml","classpath*:/spring-mvc.xml"})
@WebAppConfiguration
public class SpringTest extends AbstractJUnit4SpringContextTests {

@Resource
private UsersService usersService;

@Test
public void testSelectByPrimaryKey(){
Long id = new Long(1);
Users user = usersService.selectByPrimaryKey(id);
System.out.println(user.getUserName());
}
}

下面重点讲通过spring注解方式进行junit测试出现的问题及解决方法：

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "classpath*:/spring-mybatis.xml","classpath*:/spring-mvc.xml"})
@WebAppConfiguration

@ContextConfiguration(locations = { "classpath*:/spring-*.xml"})
