1、导包

2、配置c3p0-config.xml

     
       
          
       
        com.mysql.jdbc.Driver
           
       
        jdbc:mysql:///表名?useSSL=true
           
       
        用户名
           
       
        密码
           
       
        5
           
       
        20
         
         
           
       
        com.mysql.jdbc.Driver
           
       
        jdbc:mysql:///表名?useSSL=true
           
       
        用户名
           
       
        密码
         
        
     

3、创建C3P0Utils类

package C3P0Utils;import java.sql.Connection;import java.sql.SQLException;import javax.sql.DataSource;import com.mchange.v2.c3p0.ComboPooledDataSource;public class C3P0Utils {    private static ComboPooledDataSource dataSource = new ComboPooledDataSource();    public static DataSource getDataSource() {        return dataSource;    }    public static Connection getConnection() {        try {            return dataSource.getConnection();        } catch (SQLException e) {            throw new RuntimeException(e);        }    }}
