Spring 整合Junit单元测试

      Spring自带测试模块，是基于Junit基础上的。

添加junit和spring-test依赖，POM.xml。

<dependencies>
    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.12</version>
    </dependency> 
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <version>5.2.0.RELEASE</version>
    </dependency>
</dependencies>

纯注解方式整合junit单元测试框架测试类

@RunWith(value=SpringJUnit4ClassRunner.class)   //加载spring自有测试类

@ContextConfiguration(classes={SpringConfig.class})  //加载配置类

@ContextConfiguration(locations={"classpath:applicationContext.xml"})  //加载配置xml文件

@Autowired和@Qulifier依赖注入

//加载spring自有测试类
@RunWith(SpringJUnit4ClassRunner.class)
//加载Spring配置类或Spring配置文件
//@ContextConfiguration(classes={SpringConfig.class})
@ContextConfiguration(locations = {"classpath:applicationContext.xml"})
public class AnnotationTest {
    //依赖注入
    @Autowired
    @Qualifier("accountService")
    private AccountService accountService;

    @Test
    pulbic void test(){
        List<Account> accountList = accountService.queryAccountList();
        accountList.forEach(System.out::println);
    }
}
