java-ExceptionHandler全局异常处理

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;

/**
 * @author lijd

 */
@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);
    }
