使用Junit测试时，如果项目用Spring框架的话，配置文件载入什么的很麻烦，而且和数据库的连接经常出错，可以使用spring的注解配置，简化代码，让测试结果更有效。

## 环境 ##

IDE：idea  
JDK：1.8  
Junit：4.9  
Spring：4.26

## maven配置 ##

### spring测试相关的 ###

### Junit ###

        <version>4.9</version>
    </dependency>

## 测试代码 ##

import com.smart.domain.User;
    import org.junit.Test;
    import org.junit.runner.RunWith;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.test.context.ContextConfiguration;
    import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
    import org.springframework.transaction.annotation.Transactional;
    
    import static org.junit.Assert.assertEquals;
    
    @Transactional
    @RunWith(SpringJUnit4ClassRunner.class)//表示整合JUnit4进行测试
    @ContextConfiguration({
       "classpath:/xxx-context.xml"})  // 启动Spring容器
    public class UserServiceTest { 
        private UserService userService;
    
        @Test
        @Transactional
        public void getUserByUserName() {
            User test = new User();
            test.setUserName("admin");
            test.setPassword("123456");
            User user = userService.getByNameAndPassword(test);
            assertEquals("admin", user.getUserName());
    
            userService.loginSuccess(user);
        }
    
        @Autowired
        public void setUserService(UserService userService) {
            this.userService = userService;
        }
    }
