@POST
@Path("/login")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response login(Member member) {
    Response.ResponseBuilder builder = null;
    try {
        LogMsg.info("Login User " + member.getUsername() + " Password : "+ member.getPassword());
        member.setPassword(member.getPassword());
        repository.validateLogin(member);
         builder = Response.ok();
    } catch (ConstraintViolationException ce) {
        ErrorMessages errorMessage = new ErrorMessages(ce.getMessage(), 409, "username is wrong");  
        LogMsg.error("ConstraintViolationException  " + ce.getMessage());
        builder = Response.status(409)
                        .entity(errorMessage);  
    } catch (ValidationException e) {
        Map<String, String> responseObj = new HashMap<String, String>();
        responseObj.put("username", "Invalid Username");
        ErrorMessages errorMessage = new ErrorMessages(e.getMessage(), 404, "password is wrong");   
        LogMsg.error("ValidationException  " + e.getMessage());
        builder = Response.status(404)
                        .entity(errorMessage);                          
    } catch (Exception e) {
        Map<String, String> responseObj = new HashMap<String, String>();
        responseObj.put("error", e.getMessage());
        LogMsg.error(e.getMessage());
        builder = Response.status(Response.Status.BAD_REQUEST).entity(
                responseObj);
    }
    return builder.build();
}

注意：如果用户名和密码正确，我将200k发送给客户端。 1）如果用户名和密码错误，我们提出异常代码我需要发送给客户端的异常。任何身体都可以帮助我。

谢谢，马丹

是您可以使用例外代码发送响应。你的代码是好的只是你必须从catch块返回响应。我试图修改你的代码。

@POST
@Path("/login")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public Response login(Member member) {
    Response.ResponseBuilder builder = null;
    try {
        LogMsg.info("Login User " + member.getUsername() + " Password : "+ member.getPassword());
        member.setPassword(member.getPassword());
        repository.validateLogin(member);
         builder = Response.ok();
    } catch (ConstraintViolationException ce) {
        ErrorMessages errorMessage = new ErrorMessages(ce.getMessage(), 409, "username is wrong");  
        LogMsg.error("ConstraintViolationException  " + ce.getMessage());

        return Response.status(409).entity(errorMessage).type(MediaType.APPLICATION_JSON).build();                      
    } catch (ValidationException e) {
        Map<String, String> responseObj = new HashMap<String, String>();
        responseObj.put("username", "Invalid Username");
        ErrorMessages errorMessage = new ErrorMessages(e.getMessage(), 404, "password is wrong");   
        LogMsg.error("ValidationException  " + e.getMessage());

        return Response.status(404).entity(errorMessage).type(MediaType.APPLICATION_JSON).build();                                              
    } catch (Exception e) {
        Map<String, String> responseObj = new HashMap<String, String>();
        responseObj.put("error", e.getMessage());
        LogMsg.error(e.getMessage());

        return Response.status(400).entity(errorMessage).type(MediaType.APPLICATION_JSON).build();                                              
    }
    return builder.build();
}

处理Rest API中的异常并使用JAX-RS向客户端发送代码？
