一种方法是使用org.springframework.validation.Validator。您可以使用

@PostMapping("/abc")
public Test test((@Validated(YourValidator.class) 
     @RequestBody YourPojo pojo)) {
        return test;
   }

现在，您可以编写自己的验证

public class YourValidator implements org.springframework.validation.Validator {

        @Override
        public void validate(Object target, Errors errors) {
            YourPojo pojo = (YourPojo) target;
             boolean validJson =false;

    try {
           final ObjectMapper mapper = new ObjectMapper(); //jackson library
       String jsonInString = pojo.getJsonField() ;
   mapper.readTree(jsonInString);
           validJson= true;
        } catch (IOException e) {
           validJson= false;
        }

            errors.rejectValue("jsonField", "notValid");

         }
    }
