Spring Boot和Jersey,无法使ExceptionMapper工作

我正在使用Spring Boot + Spring Security + Jersey。

我一直在尝试做一些事情,使ExceptionMapper发生Unathorized错误,但似乎不起作用。但是,我做过的其他Mapper都能完美地工作。

这是我的代码:

未经授权的例外:

package com.ulises.usersserver.rest.exceptionsmappers;

import com.ulises.usersserver.rest.dto.ErrorDTO;
import com.ulises.usersserver.rest.dto.ErrorDTOBuilder;

import javax.ws.rs.NotAuthorizedException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;

import static com.ulises.usersserver.constants.Constants.REQUEST_ERROR_UNATHORIZED;

public class NotAuthorizedMapper implements ExceptionMapper<NotAuthorizedException> {
    @Override
    public Response toResponse(NotAuthorizedException e) {
        final ErrorDTO errorDTO = ErrorDTOBuilder.builder()
                .message(REQUEST_ERROR_UNATHORIZED)
                .build();
        return Response.status(Response.Status.UNAUTHORIZED)
                .type(MediaType.APPLICATION_JSON_TYPE)
                .entity(errorDTO)
                .build();
    }
}

其他自定义映射器效果最佳:

package com.ulises.usersserver.rest.exceptionsmappers;

import com.ulises.usersserver.rest.dto.ErrorDTO;
import com.ulises.usersserver.rest.dto.ErrorDTOBuilder;
import com.ulises.usersserver.services.exceptions.UserNotFoundException;

import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;

import static com.ulises.usersserver.constants.Constants.REQUEST_ERROR_USER_DOESNT_EXIST;

public class UserNotFoundExceptionMapper implements ExceptionMapper<UserNotFoundException> {
    @Override
    public Response toResponse(UserNotFoundException e) {
        final ErrorDTO errorDTO = ErrorDTOBuilder.builder()
                .message(REQUEST_ERROR_USER_DOESNT_EXIST)
                .build();
        return Response.status(Response.Status.NOT_FOUND).entity(errorDTO).build();
    }
}

它们当然已在 Jersey的配置中注册:

@Bean
public ResourceConfig jerseyConfig() {
    final ResourceConfig resourceConfig = new ResourceConfig();
                      ...
    resourceConfig.register(NotFoundMapper.class);
    resourceConfig.register(NotAuthorizedMapper.class);
                      ...

    return resourceConfig;
}

我似乎无法映射其他异常,例如 InternalServerErrorException (我设法通过 ExceptionMapper<Exception>,对我来说不太正确。

任何人都知道为什么会这样吗?我在这里检查了所有可能的问题,没有一个解决了这个问题。

谢谢。

好的,泽西似乎无法控制Spring Security的异常。

解决此问题的方法(必须大量挖掘)是覆盖AuthenticationEntryPoint中S-Security用于在未经授权的情况下返回401响应的方法。

因此,我创建了以下实现该接口的类:

public class CustomEntryPoint implements AuthenticationEntryPoint {

    @Override
    public void commence(HttpServletRequest request,
                         HttpServletResponse response, AuthenticationException authException) throws IOException {
        JSONObject json = new JSONObject();
        json.put("Message", "You don't have access to view this section. Please, log in with an authorized account.");
        response.addHeader("Content-Type", "application/json");
        response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
        response.getWriter().println(json);
    }
}

然后只需将此配置添加到S-Security即可将此类用作entry point

@Override
protected void configure(HttpSecurity http) throws Exception {
    http.httpBasic().authenticationEntryPoint(new CustomEntryPoint());
         ..... any other config you had .....
}
