无法将字符串 @RequestParam 转换为 javasql.Timestamp

Question

I have a unit test that checks a get request that have a TimeStamp parameter.

The UT mocks a request with the current TimeStemp to String.

Timestamp myTimeStamp = new Timestamp(Calendar.getInstance().getTimeInMillis());

MockHttpServletRequestBuilder request =get(REST_PATH).param("horarioFim", mytimeStamp.toString());

In my controller I have

    @RequestMapping(method = GET)
    public Iterable<AuditVersionModel> search(@RequestParam(required = false) Timestamp horarioFim)

TimeStamp is imported from java.sql.TimeStamp

The test fails and I have this information.

MockHttpServletResponse:
           Status = 500
    Error message = null
          Headers = {Content-Type=[application/json;charset=UTF-8]}
     Content type = application/json;charset=UTF-8
             Body = {"timestamp":"2020-05-07T23:58:48.298+0000","status":999,"error":"None","message":"Failed to convert value of type 'java.lang.String' to required type 'java.sql.Timestamp'; nested exception is org.springframework.core.convert.ConversionFailedException: Failed to convert from type [java.lang.String] to type [@org.springframework.web.bind.annotation.RequestParam @org.springframework.format.annotation.DateTimeFormat java.sql.Timestamp] for value '2020-05-07 20:58:48.201'; nested exception is java.lang.IllegalArgumentException: Invalid format: \"2020-05-07 20:58:48.201\" is malformed at \" 20:58:48.201\""}
    Forwarded URL = null
   Redirected URL = null
          Cookies = []

I tried to use @DateTimeFormat(iso = DateTimeFormat.ISO.DATE_TIME) and other variations without success, it is always the same error.

OBS1:This project is a migration from Spring Boot 1.5 to 2.0, the code is simplified. OBS2: This is a legacy system, the test is the only way to validate the request at the moment.

Answer 1

Assuming the deserialization framework you are using is expecting the date format to be in ISO format, the date passed in is not in ISO format. I tried passing in "2020-05-07T23:58:48.298+0000" to OffsetDateTime.parse() API and it threw an exception.
