客户端异常使用泽西岛 2.13 时的异常

2022-09-03 16:20:15

我在我的 Web 应用程序中使用 Jersey 2.13 来检索异步数据。在某些情况下,请求需要一些时间(即在执行复杂报告时)才能将其响应返回到客户端。

当客户端不等待异步响应(离开页面、关闭浏览器等)时,将引发 ClientAbortException。此行为符合预期,但它会用堆栈跟踪淹没我的日志文件,因为在响应返回之前取消的每个异步请求都会打印堆栈跟踪。

堆栈跟踪如下所示:

我还使用泽西岛异常映射器来映射几个异常,但这两者都不适用于

org.glassfish.jersey.server.internal.process.MappableException

也不适合

org.apache.catalina.connector.ClientAbortException

有没有办法捕获此异常并阻止打印整个堆栈跟踪?

我通过添加一个低优先级来解决此问题,该优先级检测并忽略编写响应时引发的异常。如果你在 Tomcat 上运行并且不介意对 Tomcat 类的依赖,你可以使用相当调用 ,这将消除对两个嵌套类的需求(以及对 的依赖关系,这也可以通过自定义子类轻松避免)。WriterInterceptororg.apache.catalina.connector.ClientAbortExceptionsetOutputStreamorg.apache.commons.io.output.ProxyOutputStreamOutputStream

import java.io.IOException;
import java.io.OutputStream;

import javax.annotation.Priority;
import javax.ws.rs.ext.Provider;
import javax.ws.rs.ext.WriterInterceptor;
import javax.ws.rs.ext.WriterInterceptorContext;

import org.apache.commons.io.output.ProxyOutputStream;

/**
 * Ignore exceptions when writing a response, which almost always means the
 * client disconnected before reading the full response.
 */
@Provider
@Priority(1)
public class ClientAbortExceptionWriterInterceptor implements WriterInterceptor {
    @Override
    public void aroundWriteTo(WriterInterceptorContext context) throws IOException {
        context.setOutputStream(new ClientAbortExceptionOutputStream(context.getOutputStream()));
        try {
            context.proceed();
        } catch (Throwable t) {
            for (Throwable cause = t; cause != null; cause = cause.getCause()) {
                if (cause instanceof ClientAbortException) {
                    return;
                }
            }
            throw t;
        }
    }

    private static class ClientAbortExceptionOutputStream extends ProxyOutputStream {
        public ClientAbortExceptionOutputStream(OutputStream out) {
            super(out);
        }

        @Override
        protected void handleIOException(IOException e) throws IOException {
            throw new ClientAbortException(e);
        }
    }

    @SuppressWarnings("serial")
    private static class ClientAbortException extends IOException {
        public ClientAbortException(IOException e) {
            super(e);
        }
    }
}

答案 2

我也遇到过这种情况,终于找到了“解决”这个问题的指南。

https://tutorial-academy.com/jersey-workaround-clientabortexception-ioexception/

有两个选项,第一个是当前接受的答案。另一种首选方法是添加一个 WriterInterceptor 来删除 ClientAbortException。我个人的转折是WARN记录此事件。

如果无法访问URL,我在这里添加我的实现。不要忘记在您的泽西岛上下文中注册它。

import org.apache.catalina.connector.ClientAbortException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.annotation.Priority;
import javax.ws.rs.ext.Provider;
import javax.ws.rs.ext.WriterInterceptor;
import javax.ws.rs.ext.WriterInterceptorContext;
import java.io.IOException;


@Provider
@Priority(1)
public class ClientAbortExceptionWriterInterceptor implements WriterInterceptor {
private static final Logger logger = LoggerFactory.getLogger(ClientAbortExceptionWriterInterceptor.class);

@Override
public void aroundWriteTo(WriterInterceptorContext context) throws IOException {
    try {
        context.proceed();
    } catch (Throwable t) {
        for (Throwable cause = t; cause != null; cause = cause.getCause()) {
            if (cause instanceof ClientAbortException) {
                logger.warn("Client aborted request.", cause);
                return;
            }
        }
        throw t;
    }
}

}
