My REST service includes a method that uses POST and consumes application/json. The argument of the method is another class that describes the fields required in the JSON input. Is there a way to configure Jackson to validate the input JSON before it enters the method?
@PUT
@Consumes("application/json")
public UserDataResourceObject login(UserResourceObject userResourceObject)
{
Query query = getEm().createNamedQuery("User.authorize");
if (userResourceObject == null)
{
throw new WebApplicationException(Response.Status.BAD_REQUEST);
}
query.setParameter("username", userResourceObject.getUsername());
query.setParameter("password", Utility.getMD5Value(userResourceObject.getPassword()));
Exception e = null;
try
.................
The UserResourceObject defines this structure:
{
"username" : "admin",
"password" : "123456"
}
If I modify the structure of the above JSON, I want Jackson to throw an exception, like 400 (Bad Request). How can I achieve this?
