log4j 에 proxool 데이터베이스 연결 풀 을 설치 합 니 다.

연결 탱크 는 proxool 을 사용 합 니 다.
1.먼저 보조 클래스 를 작성 합 니 다.

package com.wallimn.util;

import java.net.URL;
import java.sql.Connection;
import java.sql.DriverManager;
import org.logicalcobwebs.proxool.configuration.PropertyConfigurator;

/**

 *   ：V1.0<br/>
 */
public class DbManager {

	private static DbManager manager = new DbManager();

	static{
		URL url = ClassLoader.getSystemResource("proxool.properties");
		try {
			String fileName = url.getPath();
			PropertyConfigurator.configure(fileName);
			System.out.println("      ："+fileName);
		} catch (Exception e) {
			e.printStackTrace();
		}

	}
	public static DbManager getInstance() {
		return manager;
	}

	public Connection getConnection() {
		Connection connection = null;
		try {
			Class.forName("org.logicalcobwebs.proxool.ProxoolDriver");
			connection = DriverManager.getConnection("proxool.proxool-pool");

		} catch (Exception e) {
			e.printStackTrace();
		}
		return connection;
	}
}

2.자신의 정의 1 JDBCappender

package com.wallimn.util;

import java.sql.Connection;
import java.sql.SQLException;
import org.apache.log4j.jdbc.JDBCAppender;

public class JDBCPoolAppender extends JDBCAppender {

    public JDBCPoolAppender() {  
        super();  
    }  
	@Override
	protected Connection getConnection() throws SQLException {
		return DbManager.getInstance().getConnection();
	}

}
