数据连接池——BoneCP

最后讲的是BoneCP，到目前为止老一代的四种连接池(c3p0,DBCP,proxool,BoneCP)就到这里了

把我这几篇博客都看了的小伙伴或许会发现，这四种连接池的配置极其的相似，套路完全一样，总的来说连接池的操作还是比较简单的，下面我把BoneCP说一下

BoneCP网上的资料真的是少之又少，毕竟这个很少使用

1.导入jar包，BoneCP要的jar包比较的多

bonecp-provider-0.7.1.jar guava-r07.jar log4j-1.2.17.jar slf4j.api-1.6.1.jar slf4j-log4j12-1.6.1.jar

2.配置BoneCP文件，bonecp-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<bean id="mainDataSource" class="com.jolbox.bonecp.BoneCPDataSource" destroy-method="close">
   <property name="driverClass" value="com.mysql.jdbc.Driver" />
   <property name="jdbcUrl" value="jdbc:mysql://127.0.0.1/usta" />
   <property name="username" value="root"/>
   <property name="password" value="root"/>
   <property name="idleConnectionTestPeriod" value="60"/>
   <property name="idleMaxAge" value="240"/>
   <property name="maxConnectionsPerPartition" value="30"/>
   <property name="minConnectionsPerPartition" value="10"/>
   <property name="partitionCount" value="3"/>
   <property name="acquireIncrement" value="5"/>
   <property name="statementsCacheSize" value="100"/>
   <property name="releaseHelperThreads" value="3"/>
</bean>

3.写一个BoneCP工具类

package com.xx.train.bdqn.jdbc.utils;
//BoneCP工具类
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;


public class BONECPUtils {
	public static Connection getConnection() {
		Connection con = null;
		try {
			Class.forName("com.jolbox.bonecp.BoneCPDataSource");
			con = DriverManager.getConnection("jdbc:mysql://localhost:3306/usta", "root", "root");
		} catch (ClassNotFoundException e) {
			e.printStackTrace();
		} catch (SQLException e) {
			e.printStackTrace();
		}
		return con;
	}
}

4.写一个测试类

package com.xx.train.bdqn.jdbc.utils;

import java.sql.Connection;
import java.sql.PreparedStatement;

public class AddBONECP {
	public void addUser() throws Exception {
		Connection con = null;
		PreparedStatement pstmt = null;
		
		con = BONECPUtils.getConnection();
		String sql = "insert into user value(null,?,?)";
		pstmt = con.prepareStatement(sql);
		pstmt.setString(1, "superman");
		pstmt.setString(2, "bathman");
		int n = pstmt.executeUpdate();
		if(n>0) {
			System.out.println("更新成功");
		}else {
			System.out.println("添加失败");
		}
	}
}

5.调用测试类

package com.xx.train.bdqn.jdbc.test;

import com.xx.train.bdqn.jdbc.utils.AddBONECP;

public class TestBONECP {
	public static void main(String[] args) throws Exception {
		AddBONECP a = new AddBONECP();
		a.addUser();
	}
}
