logback自定义日志存储

1、配置lockback.xml

 
 
 
 
 
 
  
   
   %d{yyyy-MM-dd HH:mm:ss.SSS} %X{address} %-5level %logger{50} - %msg%n
  
 
 
 
 
  
   
   ${LOG_HOME}/${APP_NAME}.log.%d{yyyy-MM-dd}.log
   
   10
  
  
   
   %d{yyyy-MM-dd HH:mm:ss.SSS} %X{address} %-5level %logger{50} - %msg%n
   
  
 
 
 
  
   
    com.mysql.jdbc.Driver
    jdbc:mysql://localhost:3306/wzwsq?serverTimezone=GMT%2B8&useSSL=false&characterEncoding=utf8
    root
    123456
   
  
 
 
 
 
  
  
        
  
 
 

2、配置自定义日志操作类

import org.springframework.context.annotation.Configuration;
 
import java.lang.reflect.Method;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.sql.Timestamp;

@Configuration

    //自定义存储字段

    static final int MENU_TYPE = 1;
    static final int RECORD_ID = 2;
    static final int OPERATION_CONTENT = 3;
    static final int ADD_ID = 4;
    static final int ADD_TIME = 5;
    static final int IP = 6;
    static final int CITY = 7;
    static final int UA = 8;  
    static final StackTraceElement EMPTY_CALLER_DATA = CallerData.naInstance(); 
    static {
        // PreparedStatement.getGeneratedKeys() method was added in JDK 1.4
        Method getGeneratedKeysMethod;
        try {
            // the
            getGeneratedKeysMethod = PreparedStatement.class.getMethod("getGeneratedKeys", (Class[]) null);
        } catch (Exception ex) {
            getGeneratedKeysMethod = null;
        }
        GET_GENERATED_KEYS_METHOD = getGeneratedKeysMethod;
    }
 
    @Override
    public void start() {
        // 将写好的sql语句赋值给insertSQL
        insertSQL = buildInsertSQL();
        super.start();
    }
 
    // 自己写新增sql语句
    private static String buildInsertSQL() {
        return "INSERT INTO `operation_log`" +
                "(" +
                "`menu_type`,`record_id`," +
                "`operation_content`,`add_id`," +
                "`add_time`,`ip`," +
                "`city`,`ua`" +
                ")" +
                "VALUES (?,?,?,?,?,?,?,?)";
    }

    protected Method getGeneratedKeysMethod() {
        return GET_GENERATED_KEYS_METHOD;
    }
 
    @Override
    protected String getInsertSQL() {
        return insertSQL;
    }
 
    /**
     * 主要修改的方法
     *
     * @param stmt
     * @param event
     * @throws SQLException
     */
    private void bindLoggingEventWithInsertStatement(PreparedStatement stmt, ILoggingEvent event) throws SQLException {
        // event.getFormattedMessage() 日志打印内容
        String message = event.getFormattedMessage();
        // 如果只想存储自己打印的日志，可以这样写日志：
        // logger.info("'MENU_TYPE': '{}','RECORD_ID': '{}','OPERATION_CONTENT': '{}'",XXX,XXX,XXX)
        //判断当前日志信息是否属于自定义类型
        int MENU_TYPE_FLAG=message.indexOf("MENU_TYPE");
        int RECORD_ID_FLAG=message.indexOf("RECORD_ID");
        int OPERATION_CONTENT_FLAG=message.indexOf("OPERATION_CONTENT");
        if(MENU_TYPE_FLAG>0&&RECORD_ID_FLAG>0&&OPERATION_CONTENT_FLAG>0){
            //截取用户自定义的日志信息
            JSONObject jsonObject =JSONObject.parseObject(message);
            String menuType=jsonObject.get("MENU_TYPE").toString();
            String recordId=jsonObject.get("RECORD_ID").toString();
            String operationContent=jsonObject.get("OPERATION_CONTENT").toString();
            //获取当前使用系统的用户对象、IP、CITY、UA
            UsersModel usersModel=WebUtils.getUser();//用户登录对象
            IpInfo ipInfo=(IpInfo)WebUtils.getSession().getAttribute(Constant.IP_INFO);//用户登录IP信息
            String ip=ipInfo.getIp();
            String city=ipInfo.getCity();
            String ua=ipInfo.getUa();
 
            stmt.setString(MENU_TYPE, menuType);
            stmt.setString(RECORD_ID, recordId);
            stmt.setString(OPERATION_CONTENT, operationContent);
            stmt.setString(ADD_ID,usersModel.getId().toString());
            stmt.setTimestamp(ADD_TIME, new Timestamp(event.getTimeStamp()));
            stmt.setString(IP, ip);
            stmt.setString(CITY,city==null?"":city.toString());
            stmt.setString(UA, ua==null?"":ua.toString());
        }
    }
 
    @Override
    protected void subAppend(ILoggingEvent eventObject, Connection connection, PreparedStatement statement) throws Throwable {
        bindLoggingEventWithInsertStatement(statement, eventObject);
        // This is expensive... should we do it every time?
        int updateCount = statement.executeUpdate();
        if (updateCount != 1) {
            addWarn("Failed to insert loggingEvent");
        }
    }
 
    @Override
    protected void secondarySubAppend(ILoggingEvent eventObject, Connection connection, long eventId) throws Throwable {
    }
}

3、调用方法

private static Logger logger = LoggerFactory.getLogger(UsersController.class);
logger.info("'MENU_TYPE': '{}','RECORD_ID': '{}','OPERATION_CONTENT': '{}'",XXX,XXX,XXX);

注意事项：在logback.xml中appender标签一定的写在root标签之前

使用logback进行系统日志记录
