Spring集成Junit代码实现 ①导入spring集成Junit的坐标 <!--此处需要注意的是，spring5 及以上版本要求 junit 的版本必须是 4.12 及以上-->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-test</artifactId>
<version>5.0.2.RELEASE</version>
</dependency>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.12</version>
<scope>test</scope>
</dependency>②使用@Runwith注解替换原来的运行期 @RunWith(SpringJUnit4ClassRunner.class)
public class SpringJunitTest {
}③使用@ContextConfiguration指定配置文件或配置类 @RunWith(SpringJUnit4ClassRunner.class)
//加载spring核心配置文件
//@ContextConfiguration(value = {"classpath:applicationContext.xml"})
//加载spring核心配置类
@ContextConfiguration(classes = {SpringConfiguration.class})
public class SpringJunitTest {
}④使用@Autowired注入需要测试的对象 @RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {SpringConfiguration.class})
public class SpringJunitTest {
@Autowired
private UserService userService;
}⑤创建测试方法进行测试 @RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {SpringConfiguration.class})•public class SpringJunitTest {
@Autowired
private UserService userService;
@Test
public void testUserService(){
userService.save();
}
}
