Springboot统一异常处理并保存到数据库

/**
     * 所有异常报错
     * @param
     * @return
     * @throws Exception
     */
    @ExceptionHandler(value = Exception.class)
    @ResponseBody
    public Result allExceptionHandler(HttpServletRequest request,
                                      Exception ex) {
        String path = request.getServletPath();
        ErrorLogsUtil.error(ex,path);
        log.error("Exception:"+ ex.getMessage());
        return ResultUtils.error("操作失败");
    }

将异常 和 请求的路径作为参数传递

目前这里的数据库连接是写死的

package cn.com.connext.authority.utils;
import cn.com.connext.authority.config.DruidProperties;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.SQLException;

public class ErrorLogsUtil {
    /**
     * @param: [e]
     * @return  void
     * @Description  打印错误日志并保存到数据库
     */
    public static void error(Exception e,String path) {
        StackTraceElement stackTraceElement= e.getStackTrace()[0];
        Connection con = null;
        try {
            Class.forName("com.mysql.jdbc.Driver");
            con = (Connection) DriverManager.getConnection("jdbc:mysql://localhost:3306/demo-boot?useSSL=false&characterEncoding=utf8", "root", "root");
        } catch (SQLException e1) {
            e1.printStackTrace();
        } catch (ClassNotFoundException e1) {
            e1.printStackTrace();
        }
        PreparedStatement ps = null;
        String sql = "INSERT INTO error_logs VALUES (UUID(), NOW(), ?,?)";
        try {
            ps = con.prepareStatement(sql);
            //打印日志，错在第几行
            String errorInfo = e.toString()+",errorMassage:"+stackTraceElement+","+"errorLine:"+stackTraceElement.getLineNumber();
            ps.setString(1, errorInfo);
            ps.setString(2,path);
            ps.execute();
        } catch (SQLException e1) {
            e1.printStackTrace();
        } finally {
            try {
                if(ps != null) {
                    ps.close();
                }
                if(con != null) {
                    con.close();
                }
            } catch (SQLException e1) {
                e1.printStackTrace();
            }

        }
    }

}

SQL

DROP TABLE IF EXISTS `error_logs`;

CREATE TABLE `error_logs` (
  `id` varchar(36) NOT NULL,
  `create_time` datetime DEFAULT NULL,
  `msg` varchar(500) DEFAULT NULL,
  `path` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

数据库配置用public static 会报错
