Question

我有一个spring项目，其中在控制器中具有以下API隐含内容：

   public ResponseEntity<Boolean> testApi(
                @ApiParam @RequestParam(value = "xxx", required = false) String name) {
            boolean abc = false;  // or true
            return new ResponseEntity<>(abc, HttpStatus.OK);
    }

通过邮递员调用时，API返回的结果很好。但是，在单元测试中，我将其称为：

MappingJackson2HttpMessageConverter converter = new 
MappingJackson2HttpMessageConverter();
converter.setSupportedMediaTypes(Arrays.asList(MediaType.TEXT_PLAIN, MediaType.APPLICATION_JSON);
restTemplate.getRestTemplate().getMessageConverters().add(0, converter);
ResponseEntity<Boolean> xyz = restTemplate.getForEntity(url, Boolean.class);

我收到以下错误：

org.springframework.web.client.RestClientException: Error while extracting response for type [class java.lang.Boolean] and content type [application/json;charset=UTF-8]; nested exception is org.springframework.http.converter.HttpMessageNotReadableException: JSON parse error: Cannot deserialize instance of `java.lang.Boolean` out of START_OBJECT token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.lang.Boolean` out of START_OBJECT token

注意-我的restTemplate是org.springframework.boot.test.web.client.TestRestTemplate;

并自动连线为：

@Autowired
private TestRestTemplate restTemplate;

仅当调用API返回布尔值时，我才看到此问题。对于其他返回对象的API，效果很好

调用API返回布尔型ResponseEntity时出错
