aop配置异常日志管理

项目使用的log4g输出到文件,打印日志的时候java抛出异常未被捕获,没有进行logger.error()输出,当生产环境出现异常时不方便查找.

xml配置:

	<!-- 声明方面组件 -->
	<bean id="ExceptionLog" class="com.bofu.common.util.ExceptionLog"/>

	<!-- 配置AOP处理异常 -->
	<aop:config>
		<aop:pointcut expression="(execution (* com.bofu.bkp.service..*.*(..)))" id="pc"/>
		<aop:aspect ref="ExceptionLog">
			<aop:after-throwing method="afterException" pointcut-ref="pc" throwing="e"/>
		</aop:aspect>
	</aop:config>

ExceptionLog.java类

public class ExceptionLog {
    
    private static Logger logger = Logger.getLogger(DimensionValueServiceImpl.class);

    /**
     * 描述:程序抛出异常记录异常日志
     * @author wangn
     * @date  2020/4/1-10:02
     * @param
     * @return void
     */
    
    public void afterException(JoinPoint joinPoint, Exception e) {
        // 记录error日志
        String className = joinPoint.getTarget().getClass().getName();
        String methodName = joinPoint.getSignature().getName();

        StringBuffer message = new StringBuffer();
        StackTraceElement [] exceptionStack=e.getStackTrace();
        message.append(e.toString());
        for(StackTraceElement ste : exceptionStack) {
            message.append("\n\tat " + ste); 
        }
        logger.error("----->异常:" + e.getMessage());
        logger.error("----->异常所在类：" + className);
        logger.error("----->异常所在方法：" + methodName);
        logger.error("----->异常详细信息："+ message);

    }
}

接口自定义了一个异常信息,看打印日志

[INFO ] [10:39:21] com.bofu.bkp.exception.handler.ExceptionHandler - / by zero

log4g将会记录在error里面.再在log4g中配置输出到文件即可.记录一下方便以后遇到问题查看
