我试着测试一个控制器的方法并得到正确的异常。它仅对constraintviolationexception(javax.validation)失败,而对其他测试(如missingservletrequestparameterexception或methodargumenttypemismatchexception)失败,测试按预期工作。
下面是我的代码的一部分,在控制器(@validated)中,在方法中添加这些注解。还有控制器建议和测试。postman,当我输入错误的参数时,返回正确的响应:{“value”:500,“name”:“constraintviolationexception”,“message”:“the param1 is wrong”},但是由于某种奇怪的原因,junit要求200而不是500。
控制器
@ResponseBody
public Board method(@Min(value = 0) @Max(value = 5) @RequestParam(value = "param1", required = true) int param1,
@Min(value = 0) @Max(value = 1) @RequestParam(value = "param2", required = true) int param3){
return service.meth(param1, param2);
}
控制器建议
@ExceptionHandler(value = ConstraintViolationException.class)
public ErrorResponse handleInternalServerErrors(HttpServletRequest request, Exception ex) {
String message = "";
if(ex instanceof ConstraintViolationException) {
Map<String, Collection<String>> errors = new LinkedHashMap<>();
final String[] queryParam = {""};
((ConstraintViolationException) ex).getConstraintViolations().forEach(constraintViolation -> {
String queryParamPath = constraintViolation.getPropertyPath().toString();
queryParam[0] = queryParamPath.contains(".") ?
queryParamPath.substring(queryParamPath.indexOf(".") + 1) :
queryParamPath;
});
message = "The " + queryParam[0] + " is wrong";
}
return new ErrorResponse(
HttpStatus.INTERNAL_SERVER_ERROR.value(),
ex.getClass().getSimpleName(),
message);
}
测试
@Test
void TryToGetException() throws Exception {
given(service.meth(1231,1231)).willReturn(new CustObj());
MockHttpServletResponse response = mvc.perform(get("/endpoint")
.param("param1", "1231")
.param("param2", "1231")
).andReturn().getResponse();
assertEquals(response.getStatus(), HttpStatus.INTERNAL_SERVER_ERROR.value());
}
预期:200实际:500
为了在测试中获得异常,我应该更改什么?
提前谢谢!

通过使用
webAppContextSetup
,问题解决了。它考虑了@min,@max(在我的例子中,genarally是@valid注解),所以我可以有一个例外来测试它!
