Springboot项目：使用MockMvc测试get和post接口（含单个和多个请求参数场景）

一、引入MockMvc依赖

使用MockMvc，必须要引入依赖

复制代码

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

二、具体演示

1、GET请求（单个参数）

测试类代码

复制代码

@ExtendWith(MockitoExtension.class)
class AppControllerTest {

    private MockMvc mockMvc;

    @Mock
    private IDB2PatrolResultService idb2PatrolResultService;
    @InjectMocks
    private DB2PatrolResultController db2PatrolResultController;

    @BeforeEach
    void setUp() {
        this.mockMvc = MockMvcBuilders.standaloneSetup(db2PatrolResultController).build();
    }

    @Test
    void testGet() throws Exception {
        this.mockMvc.perform(MockMvcRequestBuilders.get("/dbm/patrolResult/trigger/{itemCode}","121"))
            .andExpect(status().isOk())
            .andDo(MockMvcResultHandlers.print())
            .andReturn();
    }
}

controller类代码

复制代码

	@GetMapping("/trigger/{itemCode}")
    public R<Void> execSchedule(@PathVariable("itemCode") String itemCode) {
        return patrolResultService.execSchedule(itemCode);
    }

2、GET请求（多个参数）

测试类代码：

复制代码

@ExtendWith(MockitoExtension.class)
class AppControllerTest {

    private MockMvc mockMvc;

    @Mock
    private IDB2PatrolResultService idb2PatrolResultService;
    @InjectMocks
    private DB2PatrolResultController db2PatrolResultController;

    @BeforeEach
    void setUp() {
        this.mockMvc = MockMvcBuilders.standaloneSetup(db2PatrolResultController).build();
    }

    @Test
    void testPatrolResult() throws Exception {
        PatrolQueryConfig patrolQueryConfig = new PatrolQueryConfig();
        patrolQueryConfig.setItemLevel("0");
        patrolQueryConfig.setStatusType("0");
        String jsonStr = JSONUtil.toJsonStr(patrolQueryConfig);
        this.mockMvc.perform(MockMvcRequestBuilders.get("/dbm/patrolResult/list")
                .param("itemLevel","1")
                .param("statusType","2"))
            .andExpect(status().isOk())
            .andDo(MockMvcResultHandlers.print())
            .andReturn();
    }
}

controller类代码

复制代码

	@GetMapping("/list")
    public TableDataInfo<PatrolResult> getRunStatsDataAggs(PatrolQueryConfig patrolQueryConfig) {
        List<PatrolResult> patrolResults = patrolResultService.getPatrolHisResultAggs(patrolQueryConfig);
        return TableDataInfo.build(patrolResults);
    }

3、POST请求（多个参数）

测试类代码

复制代码

@ExtendWith(MockitoExtension.class)
class AppControllerTest {

    private MockMvc mockMvc;

    @Mock
    private IDB2PatrolResultService idb2PatrolResultService;
    @InjectMocks
    private DB2PatrolResultController db2PatrolResultController;

    @BeforeEach
    void setUp() {
        this.mockMvc = MockMvcBuilders.standaloneSetup(db2PatrolResultController).build();
    }

    @Test
    void testPost() throws Exception {
        PatrolQueryConfig patrolQueryConfig = new PatrolQueryConfig();
        patrolQueryConfig.setItemLevel("0");
        patrolQueryConfig.setStatusType("0");
        String jsonStr = JSONUtil.toJsonStr(patrolQueryConfig);
        this.mockMvc.perform(MockMvcRequestBuilders.post("/dbm/patrolResult/list")
                .contentType(MediaType.APPLICATION_JSON_VALUE)
                .content(jsonStr)
                .header(HttpHeaders.ACCEPT,"application/json"))
            .andExpect(status().isOk())
            .andDo(MockMvcResultHandlers.print())
            .andReturn();
    }
}

controller类代码

复制代码

	@PostMapping("/list")
    public TableDataInfo<PatrolResult> getRunStatsDataAggs(@RequestBody PatrolQueryConfig patrolQueryConfig) {
        List<PatrolResult> patrolResults = patrolResultService.getPatrolHisResultAggs(patrolQueryConfig);
        return TableDataInfo.build(patrolResults);
    }

三、总结

使用MockMvc可以做到controller层的测试。
在初始化mockMvc的时候:
（1）如果想测试单个controller
mockMvc = MockMvcBuilders.standaloneSetup(mockMvcController).build();
（2）如果想测试所有controller
mockMvc = MockMvcBuilders.webAppContextSetup(context).build();
