MockMvc测试controller

1.情景
Spring的MockMvc框架模拟了SpringMvc的很多功能，几乎和运行在servlet容器里的应用程序。通过这么一套和springmvc的模拟环境来测试controller更加符合真实测试情况。

2.实际操作
先在pom.xml里导入对应的测试jar包

            org.springframework.boot
            spring-boot-starter-test
        

然后对应类的实现

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
@WebAppConfiguration
public class MockMvcTest {
    private MockMvc mvc;
    @Autowired
    private WebApplicationContext context;

    @Before
    public void setupMockMvc() throws Exception {
        mvc = MockMvcBuilders.webAppContextSetup(context).build();
    }

    @Test
    public void testHelloWorld() throws Exception {
        System.out.println(MockMvcResultMatchers.content().toString());
        mvc.perform(MockMvcRequestBuilders.get("/api/helloWorld"))
                .contentType(MediaType.APPLICATION_FORM_URLENCODED)  //数据的格式
　　　　　　　　  .param("pcode","root")
                .andExpect(MockMvcResultMatchers.status().isOk());
    }

    @Test
    public void testSaveUserIndex() throws Exception {
        HbdbUserIndex hbdbUserIndex = new HbdbUserIndex();

        ObjectMapper objectMapper = new ObjectMapper();
        ObjectWriter objectWriter = objectMapper.writer().withDefaultPrettyPrinter();
        String requestJson = objectWriter.writeValueAsString(hbdbUserIndex);
        mvc.perform(MockMvcRequestBuilders.post("/api/userIndex").contentType(MediaType.APPLICATION_JSON).content(requestJson))
            .andExpect(MockMvcResultMatchers.status().isOk());
    }

}

get方法传参和post传参方式如上。
