springmvc配置文件：

<!-- 定义全局异常处理，只有一个全局异常处理器起作用 -->

    <bean id="exceptionResolver" class="net.nblh.utils.common.OverallExceptionResolver"></bean>

OverallExceptionResolver：

package net.nblh.utils.common;

import org.apache.log4j.Logger;

import org.springframework.web.bind.annotation.ControllerAdvice;

import org.springframework.web.bind.annotation.ExceptionHandler;

/**

@ControllerAdvice//Controller增强类

public class OverallExceptionResolver {

    private static final Logger logger = Logger.getLogger(OverallExceptionResolver.class);

    /**

     * 处理所有不可知的异常

     * @param e

     */

    @ExceptionHandler(Exception.class)

    public static void handlerException(Exception e) {

        String stackTrace = e.getStackTrace().length>0?e.getStackTrace()[0].toString():"";

        String errorMsg = "系统未捕获的异常handlerException：error:"+e.toString()+"\n"+"stackTrace:"+stackTrace;

        System.out.println(errorMsg);

        logger.error(errorMsg);

    }
