Question

我有一个自定义ExceptionMapper，可以捕获我的自定义RuntimeException。问题是，当我抛出自定义ExceptionMapper时，Exception不会被调用。

我已在@Provider课程中设置ExceptionMapper，并在web.xml注册为：{/ p>

<context-param>
    <param-name>resteasy.providers</param-name>
    <param-value>com.package.myMapper</param-value>
</context-param>

我的映射器是：

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

@Provider
public class ResponseExceptionMapper implements ExceptionMapper<ResponseException>{

    @Override
    public Response toResponse(ResponseException arg0) {
        // TODO Auto-generated method stub
        System.out.println("in my mapper");
        return Response.status(513).entity(arg0.getMessage()).build();  
    }

}

我的例外：

    public class ResponseException extends RuntimeException {

    public ResponseException() {
        super();
    }

    public ResponseException(String msg) {
        super(msg);
    }

    public ResponseException(String msg, Exception e) {
        super(msg, e);
    }
}

我做错了什么？...

尝试让您的ResponseException扩展Exception而不是RuntimeException。似乎resteasy和jboss正在捕捉你的异常，而不是你的提供者，我有完全相同的问题，它解决了扩展Exception：


    public class ResponseException extends Exception {

        public ResponseException() {
            super();
        }


        public ResponseException(String msg) {
            super(msg);
        }

        public ResponseException(String msg, Exception e) {
            super(msg, e);
        }
    }

以及异常映射器的示例：


    import org.apache.log4j.Logger;

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

    @Provider
    public class BadRequestExceptionMapper implements ExceptionMapper {

        private static final Logger log = Logger.getLogger(BadRequestExceptionMapper.class);

        @Override
        public Response toResponse(BadRequestException e) {

            log.info("Bad request: " + e.getMessage());

            return Response.status(Response.Status.BAD_REQUEST).entity(e.getMessage()).build();
        }
    }

ExceptionMapper不处理我的异常。 JBOSS
