hibernate c3p0配置

要使用c3p0,首先在hibernate中选择required的jar和optional的c3p0目录的jar包，再加上mysql的驱动。

  



  
	
    
    
     com.mysql.jdbc.Driver
     
    
     jdbc:mysql://localhost:3306/simpledb
     
    
     root
     
    
     system
     
    
     20
     
    
     5
     
    
     5000
     
    
     100
     
    
     3000
     
    
     2
     
    
     true
     
    
     org.hibernate.dialect.MySQLDialect
     
    
     create
     
     
   

  

准备映射的类。

package com.lin.domain;

public class News {
	private int id;
	private String title;
	private String content;

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}

	public String getTitle() {
		return title;
	}

	public void setTitle(String title) {
		this.title = title;
	}

	public String getContent() {
		return content;
	}

	public void setContent(String content) {
		this.content = content;
	}

}

映射文件：News.hbm,xml

System.out.println("starting ............");
Configuration conf = new Configuration().configure();
SessionFactory factory = conf.buildSessionFactory();
Session session = factory.openSession();
Transaction tx = session.beginTransaction();
News n = new News();
n.setId(1);
n.setTitle("wanku");
n.setContent("this is wanku project!!!");
session.save(n);
tx.commit();
session.close();
factory.close();
System.out.println("ending................");
