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);
    }
}
