引入Web模块
当前pom.xml中
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
- spring-boot-starter:核心模块,包括自动配置支持,日志和
- spring-boot-starter-test:测试模块,包括JUnit,Hamcrest,Mockito
- spring-boot-starter-web:web模块
编写HelloWorld服务
创建HellController类
启动主程序,打开浏览器访问http://localhost:8080/hello,可以看到页面输出Hello World
编写单元测试用例
@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = MockServletContext.class)
@WebAppConfiguration
public class DemotestApplicationTests {
private MockMvc mvc;
@Before
public void setUp() throws Exception {
mvc = MockMvcBuilders.standaloneSetup(new HelloConteroller()).build();
}
@Test
public void getHello() throws Exception {
mvc.perform(MockMvcRequestBuilders.get("/hello")
.accept(MediaType.APPLICATION_JSON))
.andExpect(status().isOk())
.andExpect(content().string(equalTo("Hello World")));
}
}
使用MockServletContext来创建一个空的WebApplicationContext,这样我们创建的HellController就可以在@Before函数中创建并传递到MockMvcBuilders.standaloneSetup函数中。
注意引入下面的内容,让status、context、equalTo函数可用
import static org.hamcrest.Matchers.equalTo;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.content;
import static org.springframework.test.web.servlet.result.MockMvcResultMatchers.status;
