我有问题LocalDateTime
反序列化Junit
测试。我有简单的REST API
返回一些DTO
目的。当我呼叫端点时,响应没有问题 - 它是正确的。然后我尝试编写单元测试,得到MvcResult
并使用ObjectMapper
将其转换为我的DTO
目的。但我仍然收到:
com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.time.LocalDateTime` out of START_ARRAY token
at [Source: (String)"{"name":"Test name","firstDate":[2019,3,11,18,34,43,52217600],"secondDate":[2019,3,11,19,34,43,54219000]}"; line: 1, column: 33] (through reference chain: com.mylocaldatetimeexample.MyDto["firstDate"])
我正在尝试与@JsonFormat
并添加compile group: 'com.fasterxml.jackson.datatype', name: 'jackson-datatype-jsr310', version: '2.9.8'
to my build.gradle
但我用Spring Boot 2.1.3.RELEASE
所以它参与其中。我不知道如何解决它。我的简单端点和单元测试如下:
@RestController
@RequestMapping("/api/myexample")
public class MyController {
@GetMapping("{id}")
public ResponseEntity<MyDto> findById(@PathVariable Long id) {
MyDto myDto = new MyDto("Test name", LocalDateTime.now(), LocalDateTime.now().plusHours(1));
return ResponseEntity.ok(myDto);
}
}
MyDto 类
public class MyDto {
private String name;
private LocalDateTime firstDate;
private LocalDateTime secondDate;
// constructors, getters, setters
}
单元测试
public class MyControllerTest {
@Test
public void getMethod() throws Exception {
MyController controller = new MyController();
MockMvc mockMvc = MockMvcBuilders.standaloneSetup(controller).build();
MvcResult mvcResult = mockMvc.perform(MockMvcRequestBuilders.get("/api/myexample/1"))
.andExpect(MockMvcResultMatchers.status().isOk()).andReturn();
String json = mvcResult.getResponse().getContentAsString();
MyDto dto = new ObjectMapper().readValue(json, MyDto.class);
assertEquals("name", dto.getName());
}
}
