Spring整合JUnit

1. 安装spring-test和junit依赖，其中junit依赖的版本不低于4.12

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>5.3.4</version>
</dependency>
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>test</scope>
</dependency>

2. 给测试类增加注解

• @RunWith(SpringJUnit4ClassRunner.class) 修改JUnit的main方法
• @ContextConfiguration() 通过locations属性指定XML配置文件或通过classess属性指定配置类

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {SpringConfig.class})
public class RoleServiceTest {
    @Autowired
    private RoleService roleService;
}

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:Beans.xml"})
public class RoleServiceTest {
    @Autowired
    private RoleService roleService;
}
