系统错误日志实现_JAVA

错误日志实现比较简单，主要利用@ControllerAdvice这个注解。

下面代码中，如果项目中并没有使用dubbo可以改下返回语句，另外我还自定义了一个BusinessException异常类，可以根据自己项目中的情况选择保留或者去除。

import cc.lood.plugingroup.gate.common.util.code.DubboCodeUtils;
    import com.alibaba.fastjson.JSONObject;
    import org.apache.commons.lang.StringUtils;
    import org.apache.commons.lang.exception.ExceptionUtils;
    import org.apache.log4j.Logger;
    import org.springframework.web.bind.annotation.ControllerAdvice;
    import org.springframework.web.bind.annotation.ExceptionHandler;
    import org.springframework.web.bind.annotation.ResponseBody;
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import java.util.Map;
    
    
    @ControllerAdvice
    public class GlobalExceptionHandler {
    
        private static final Logger logger = org.apache.log4j.Logger.getLogger(GlobalExceptionHandler.class);
    
        /**
         * 处理所有不可知的异常
         *
         * @param
         * @return
         */
        @ExceptionHandler(Exception.class)
        @ResponseBody
        private String handleException(Exception e, HttpServletRequest request, HttpServletResponse response) {
    
            Map dataMap = request.getParameterMap();
            for (Object key : dataMap.keySet()) {
                String[] dataString = (String[]) dataMap.get(key);
                logger.error("执行记录错误日志操作:"+String.format("{%s}","Param:" + key + " = " + StringUtils.join(dataString, ",")));
            }
            request.setAttribute("flag",false);
            logger.error(ExceptionUtils.getFullStackTrace(e));
            return DubboCodeUtils.to(response, "11111", e);
    
        }
    
        /**
         * 处理所有业务的异常
         *
         * @param e
         * @return
         */
        @ExceptionHandler(BusinessException.class)
        @ResponseBody
        private String handleException(HttpServletRequest request, HttpServletResponse response,BusinessException e) {
            logger.error(e.getMessage(), e);
            return DubboCodeUtils.to(response, "11111", e);
        }
    }
