Junit测试中LocalDateTime反序列化的问题
我LocalDateTime
在Junit
测试中反序列化有问题。我有简单的REST API
返回一些DTO
对象。当我呼叫端点时,响应没有问题-
是正确的。然后,我尝试编写单元测试,获取MvcResult
并将其ObjectMapper
转换为我的DTO
对象。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@JsonFormat
并添加compile group: 'com.fasterxml.jackson.datatype', name:
'jackson-datatype-jsr310', version:
'2.9.8'到我的应用程序中,build.gradle
但是我使用了Spring Boot
2.1.3.RELEASE它,因此它参与其中。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());
}
}
回答:
您ObjectMapper
在测试中创建新的:
MyDto dto = new ObjectMapper().readValue(json, MyDto.class);
尝试ObjectMapper
从Spring
上下文注入或手动注册模块:
mapper.registerModule(new JavaTimeModule());
