這篇文章主要介紹了logback如何自定義日志存儲的操作，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教

logback自定義日志存儲

1、配置lockback.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration> 
 <property name="LOG_HOME" value="/wzwsq-log" />
 <property name="APP_NAME" value="wzwsq" />
 
 <!-- 控制臺輸出 -->
 <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
  <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
   <!--格式化輸出：%d表示日期，%thread表示線程名，%-5level：級別從左顯示5個字符寬度%msg：日志消息，%n是換行符 -->
   <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %X{address} %-5level %logger{50} - %msg%n</pattern>
  </encoder>
 </appender>
 
 <!-- 按照每天生成日志文件 -->
 <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender">
  <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
   <!--日志文件輸出的文件名 -->
   <FileNamePattern>${LOG_HOME}/${APP_NAME}.log.%d{yyyy-MM-dd}.log</FileNamePattern>
   <!--日志文件保留天數(shù) -->
   <MaxHistory>10</MaxHistory>
  </rollingPolicy>
  <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
   <!--格式化輸出：%d表示日期，%thread表示線程名，%-5level：級別從左顯示5個字符寬度%msg：日志消息，%n是換行符 -->
   <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %X{address} %-5level %logger{50} - %msg%n</pattern>
   <!--<pattern>%-4relative [%thread] %-5level %logger{35} - %msg%n</pattern> -->
  </encoder>
 </appender>
 <!--連接數(shù)據(jù)庫配置 class：日志保存操作類 -->
 <appender name="db_classic_mysql_pool" class="wzwsq.config.LogDBAppender">
  <connectionSource class="ch.qos.logback.core.db.DataSourceConnectionSource">
   <dataSource class="org.apache.commons.dbcp.BasicDataSource">
    <driverClassName>com.mysql.jdbc.Driver</driverClassName>
    <url>jdbc:mysql://localhost:3306/wzwsq?serverTimezone=GMT%2B8&amp;useSSL=false&amp;characterEncoding=utf8</url>
    <username>root</username>
    <password>123456</password>
   </dataSource>
  </connectionSource>
 </appender>
 
 <!-- 日志輸出級別 -->
 <root level="info">
  <appender-ref ref="STDOUT" />
  <appender-ref ref="FILE" />
        <!--添加自定義操作配置-->
  <appender-ref ref="db_classic_mysql_pool" />
 </root>
 
</configuration>

2、配置自定義日志操作類

import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.db.DBAppenderBase;
import com.alibaba.fastjson.JSONObject;

import java.lang.reflect.Method;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.SQLException;
import java.sql.Timestamp;

@Configuration

    protected static final Method GET_GENERATED_KEYS_METHOD;
    //插入sql
    protected String insertSQL;
 
    //自定義存儲字段

     * ip：根據(jù)IP對應城市

     * */
    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() {
        // 將寫好的sql語句賦值給insertSQL
        insertSQL = buildInsertSQL();
        super.start();
    }
 
    // 自己寫新增sql語句
    private static String buildInsertSQL() {
        return "INSERT INTO `operation_log`" +
                "(" +
                "`menu_type`,`record_id`," +
                "`operation_content`,`add_id`," +
                "`add_time`,`ip`," +
                "`city`,`ua`" +
                ")" +

    }
 
    @Override
    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() 日志打印內容
        String message = event.getFormattedMessage();
        // 如果只想存儲自己打印的日志，可以這樣寫日志：
        // logger.info("'MENU_TYPE': '{}','RECORD_ID': '{}','OPERATION_CONTENT': '{}'",XXX,XXX,XXX)
        //判斷當前日志信息是否屬于自定義類型
        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){
            //截取用戶自定義的日志信息
            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();
            //獲取當前使用系統(tǒng)的用戶對象、IP、CITY、UA
            UsersModel usersModel=WebUtils.getUser();//用戶登錄對象
            IpInfo ipInfo=(IpInfo)WebUtils.getSession().getAttribute(Constant.IP_INFO);//用戶登錄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、調用方法

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

注意事項：在logback.xml中appender標簽一定的寫在root標簽之前
