java.lang.IllegalArgumentException: java.text.ParseException: Конец заголовка

Question

Я столкнулся с IllegalArgumentException при отправке почтового запроса на спокойный веб-сервис. Если я прокомментирую метод для почтового запроса (getEmplByPostReqParam()), тогда код отлично подходит для получения запроса, но с getEmplByPostReqParam(), все запросы бросков IllegalArgumentException.

Помогите нам решить проблему.

код услуги

Web:

@Path("/employee") 
public class EmployeeInfoService { 

    // This method is called if TEXT_PLAIN is request 
    @GET 
    @Path("/get/{id}") 
    @Produces(MediaType.APPLICATION_ATOM_XML) 
    public Employee getEmplById(@PathParam("id") String id) { 
     System.out.println("sayPlainTextHello"); 
     EmployeeDAO dbHandler = new EmployeeDAOImpl(); 
     Employee fetchedEmployee = dbHandler.findEmployee(Integer.parseInt(id)); 
     return fetchedEmployee; 
    } 

    @GET 
    @Path("/get") 
    @Produces(MediaType.APPLICATION_ATOM_XML) 
    public Employee getEmplByGetReqParam(@QueryParam("param1") String id) { 
     System.out.println("getEmplByGetReqParam"); 
     EmployeeDAO dbHandler = new EmployeeDAOImpl(); 
     Employee fetchedEmployee = dbHandler.findEmployee(Integer.parseInt(id)); 
     return fetchedEmployee; 
    } 

    @POST 
    @Path("/get") 
    @Produces("MediaType.TEXT_PLAIN") 
    public String getEmplByPostReqParam(@FormParam("param1") String id) { 
     System.out.println("getEmplByPostReqParam"); 
     EmployeeDAO dbHandler = new EmployeeDAOImpl(); 
     Employee fetchedEmployee = dbHandler.findEmployee(Integer.parseInt(id)); 
     return fetchedEmployee.toString(); 
    }

Я использовал два клиента для тестирования службы: клиент 1. Google Chrome в Advance Rest

url - http://myhost:14443/de.vogella.jersey.first/rest/employee/get 
payload - [param1: 1] 
method type - [post] 

1. ядро ​​Java код

   String url = "http://myhost:14443/de.vogella.jersey.first/rest/employee/get";

Answer 1

Я решил проблему, изменив getEmplByPostReqParam() следующим образом:

@POST 
@Path("/get") 
public Response getEmplByPostReqParam(@FormParam("param1") String id) { 
    System.out.println("getEmplByPostReqParam"); 
    EmployeeDAO dbHandler = new EmployeeDAOImpl(); 
    Employee fetchedEmployee = dbHandler.findEmployee(Integer.parseInt(id)); 
    ResponseBuilder rb = new ResponseBuilderImpl(); 
    rb.type(MediaType.APPLICATION_ATOM_XML); 
    rb.entity(fetchedEmployee); 
    return rb.build(); 
} 

Это работает хорошо для меня, если их какой-то лучший подход или их что-то не так с этим подход, пожалуйста, напишите комментарий.

Answer 2

Если вы заметили, что ваш комментарий аннотации (@Produces) передается в двойных кавычках. удалить двойные кавычки, и он должен работать

@Produces ("MediaType.TEXT_PLAIN")

должен выглядеть ниже

@Produces (MediaType.TEXT_PLAIN)
