用java端，通过log4j 把日志写入scribe 日志系统

用java端，通过log4j 把日志写入scribe 日志系统。

 

 

一、生成scribe客户端

• 生成 java客户端api

   A. 修改配置文件scribe.thrift
      cd /usr/local/scribeInstall/scribe/if
      vi scribe.thrift
      修改scribe.thrift文件: 把 include "fb303/if/fb303.thrift" 改成
      include "[thrift解压路径]/thrift-0.5.0/contrib/fb303/if/fb303.thrift"
   B. 生成 java客户端api     
      运行命令 thrift --gen java scribe.thrift
      运行后会生成一个‘gen-java’的文件夹.里面会有3个java类，封装了所有java客户端发送log所需要的api。

 

 

• 生成客户端代码所需要的jar包

   A. 如果之前没设置ANT_HOME 和 PATH 请先设置这两个环境变量
      export ANT_HOME=/usr/local/apache-ant-1.8.0
      export PATH=$PATH:$ANT_HOME/bin
   B. 生成libthrift.jar
      cd /usr/local/scribeInstall/thrift-0.2.0/lib/java
      ant 
      (如果没有错误在本文夹夹下会生成libthrift.jar)
   C. 生成libfb303.jar

 

 cd /usr/local/scribeInstall/thrift-0.2.0/contrib/fb303/java

ant

ant 执行成功后 libfb303.jar 会出现在/usr/local/scribeInstall/contrib/fb303/java/build/lib下

 

 

二、创建项目，运行测试 

• 创建项目

     A.在eclipse 创建普通java项目

     B.在项目中导入以下jar

     

    C.在项目中添加gen-java 文件夹里的三个java类。

•    编写项目

    编写log4j 的scribe appender 

    AsyncScribeAppender.java:

    

package com.logtest;

import org.apache.log4j.AsyncAppender;
/**
 * log4j 的scribe appender
 * 用ScribeAppender 类连接scribe服务器，并把日志写如scribe
 * @author ninja
 */
public class AsyncScribeAppender extends AsyncAppender {

    private String hostname;
    private String scribeHost;
    private int scribePort;
    private String scribeCategory;
    private String encoading;

    public String getHostname() {
        return hostname;
    }

    public void setHostname(String hostname) {
        this.hostname = hostname;
    }

    public String getScribeHost() {
        return scribeHost;
    }

    public void setScribeHost(String scribeHost) {
        this.scribeHost = scribeHost;
    }

    public int getScribePort() {
        return scribePort;
    }

    public void setScribePort(int scribePort) {
        this.scribePort = scribePort;
    }

    public String getScribeCategory() {
        return scribeCategory;
    }

    public void setScribeCategory(String scribeCategory) {
        this.scribeCategory = scribeCategory;
    }

    public String getEncoading() {
        return encoading;
    }

    public void setEncoading(String encoading) {
        this.encoading = encoading;
    }

    @Override
    public void activateOptions() {
        super.activateOptions();
        synchronized (this) {
            ScribeAppender scribeAppender = new ScribeAppender();
            scribeAppender.setLayout(getLayout());
            scribeAppender.setHostname(getHostname());
            scribeAppender.setScribeHost(getScribeHost());
            scribeAppender.setScribePort(getScribePort());
            scribeAppender.setScribeCategory(getScribeCategory());
            scribeAppender.setEncoding(getEncoading());
            scribeAppender.activateOptions();
            addAppender(scribeAppender);
        }
    }

    @Override
    public boolean requiresLayout() {
        return true;
    }

}
