如何捕捉并忽略org.apache.catalina.connector.ClientAbortException

我想捕捉并忽略下面的tomcat ClientAbortException。因为我的程序没有必要对此加以关注。如何捕捉并忽略org.apache.catalina.connector.ClientAbortException

任何想法如何以及在哪里可以捕获此异常？下面是例外：

，因为你可能不希望依赖于卡特琳娜，可以忽略这样的例外（我假设ClientAbortException是原因）：

String simpleName = e.getCause().getClass().getSimpleName(); 
if (simpleName.equals("ClientAbortException")) { 
    // ignore 
} else { 
    // do whatever you do 
}

ClientAbortException延伸IOException。你可以试试下面的代码捕获异常：

try { 
    // codes 
    out.write("xyz"); // throws IOException 
} catch (org.apache.catalina.connector.ClientAbortException ca) { 
    System.out.println("ClientAbortException caught"); 
} catch (IOException ioe) { 
    System.out.println("i/o exception raised. abrorting."); 
}

但我的问题更像是我应该在代码中捕获这个异常？我需要在哪个课程中添加此catch块？ – user3007165

因为你需要发布你的代码，并尝试调试你的代码，以便你可以确切地知道你在哪一点得到异常，然后尝试把代码放在try catch中。 –

在春季4，你会把它放在一个带有@ControllerAdvice注解的类中。诀窍是只抑制ClientAbortException同时允许所有其他IOException被视为错误处理或注销，不会对你的容器API引入编译/运行依赖：

import java.io.IOException; 
import java.util.logging.Level; 
import java.util.logging.Logger; 

//import org.apache.catalina.connector.ClientAbortException; // We don't want this dependency. 
import org.springframework.web.bind.annotation.ControllerAdvice; 
import org.springframework.web.bind.annotation.ExceptionHandler; 
import org.springframework.web.servlet.NoHandlerFoundException; 

@ControllerAdvice 
public final class ErrorController 
{ 
    @ExceptionHandler(NoHandlerFoundException.class) 
    public String handleNoHandlerFoundException(final NoHandlerFoundException ex) 
    { 
     return "notFoundPage"; 
    } 

    @ExceptionHandler(IOException.class) 
    public String handleAbortedConnection(final IOException ex) 
    { 
     // avoids compile/runtime dependency by using class name 
     if (ex.getClass().getName().equals("org.apache.catalina.connector.ClientAbortException")) 
     { 
      return null; 
     } 

     // log and return error page for any other IOExceptions 
     if (LOGGER.isLoggable(Level.WARNING)) 
     { 
      LOGGER.log(Level.WARNING, "IO Error", ex); 
     } 

     return "errorPage"; 
    } 

    @ExceptionHandler(Exception.class) 
    public String handleException(final Exception ex) 
    { 
     if (LOGGER.isLoggable(Level.SEVERE)) 
     { 
      LOGGER.log(Level.SEVERE, "Server Error", ex); 
     } 
     return "errorPage"; 
    } 
}

感谢这个答案提供缺少的部分，我们return null for the view name to avoid throwing a SocketException on the closed OutputStream。
