Spring Boot、全局异常处理和测试

Question

使用Spring Boot有几种方法可以解决这个问题。并且我选择将@ControllerAdvice与@ExceptionHandler方法一起使用。

@ControllerAdvice
public class GlobalExceptionHandler {

@ExceptionHandler(EntityNotFoundException.class)
public ResponseEntity<ErrorDetails> handleNotFound(EntityNotFoundException exception, HttpServletRequest webRequest) {
    ErrorDetails errorDetails = new ErrorDetails(
            new Date(),
            HttpStatus.NOT_FOUND,
            exception,
            webRequest.getServletPath());

    return new ResponseEntity<>(errorDetails, HttpStatus.NOT_FOUND);
 }
}

因此，当抛出异常时，新的处理程序会捕获异常并返回一个包含消息的漂亮的json，如：

{
"timestamp": "2018-06-10T08:10:32.388+0000",
"status": 404,
"error": "Not Found",
"exception": "EntityNotFoundException",
"message": "Unknown employee name: test_name",
"path": "/assignments"
}

实施-没那么难。最难的部分是测试。

@Test
public void shouldShow404() throws Exception {
    mockMvc.perform(post("/assignments")
            .contentType(APPLICATION_JSON_UTF8_VALUE)
            .content(new ClassPathResource("rest/assign-desk.json").getInputStream().readAllBytes()))
            .andExpect(status().isNotFound());
}

欢迎有任何想法。谢谢你！

找到答案了。

它可能涉及的人：

设置apon类：

@RunWith(SpringRunner.class)
@SpringBootTest
@AutoConfigureMockMvc
public class GlobalExceptionHandlerTest{
//
}

@Test
public void catchesExceptionWhenEntityNotFoundWithSpecificResponse() throws Exception {

    mockMvc.perform(post("/assignments")
            .contentType(MediaType.APPLICATION_JSON_UTF8)
            .content(new ClassPathResource("rest/assign-desk.json").getInputStream().readAllBytes()))
            .andExpect(status().isNotFound())
            .andExpect(jsonPath("status").value(404))
            .andExpect(jsonPath("exception").value("EntityNotFoundException"))
            .andExpect(jsonPath("message").value("Unknown employee name: abc"));
}
