RestEASY + Jboss 7.x -当Accept与@Produces值不匹配时，你能默认使用first @Path吗？

import javax.ws.rs.ext.ExceptionMapper;

@Provider
public class NotAcceptableExceptionMapper implements ExceptionMapper<NotAcceptableException> {

    @Override
    public Response toResponse(NotAcceptableException exception) {
        if (!exception.getAcceptableMediaTypes().isEmpty()) {
            // 获取第一个@Path对应的资源
            String firstPath = exception.getAcceptableMediaTypes().get(0).toString();
            // 构建响应
            return Response.status(Response.Status.OK)
                    .entity("Using first @Path: " + firstPath)
                    .type(MediaType.TEXT_PLAIN)
                    .build();
        }
        return Response.status(Response.Status.NOT_ACCEPTABLE).build();
    }
}
