jersey2 和 jboss 7.11 未调用 ExceptionMapper

Question

我的 jaxrs 项目中有一个异常映射器来捕获所有 NotFoundException 并格式化响应。在 Tomcat 中运行时，抛出异常时会调用异常映射器。我现在不得不转移到 JBoss，一切正常，除了不再调用异常映射器。

异常映射器

import javax.ws.rs.NotFoundException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.Response;
import javax.ws.rs.ext.ExceptionMapper;
import javax.ws.rs.ext.Provider;

import com.openet.modules.config.server.rest.response.ErrorInfo;
import com.openet.modules.config.server.rest.response.ErrorResponse;

@Provider
public class NotFoundExceptionMapper implements  ExceptionMapper<NotFoundException> {
    public Response toResponse(NotFoundException ex) {
        ex.printStackTrace();
        return Response
            .status(ex.getResponse().getStatus())
            .entity(new ErrorResponse(new ErrorInfo(ex)))
            .type(MediaType.APPLICATION_JSON)
            .build();
    }
}

从 jersey 的 2.7 版移至 2.24 版，现在调用异常映射器。
