那个JDBCUtil里面都不知道写什么,在UserDaoImpl里面调用的时候QueryRunner queryRunner = new QueryRunner(JDBCUtil.getDataSource());的getDataSource就报错了。
JDBCUtil源码
package com.imooc.utils;
import java.beans.PropertyVetoException;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import com.mchange.v2.c3p0.ComboPooledDataSource;
import com.mchange.v2.c3p0.DataSources;
public class JDBCUtils {
private static String url = "jdbc:mysql://localhost:3306/regist_web";
private static String user = "root";
private static String passwd = "20142266";
private static String driver = "com.mysql.jdbc.Driver";
public static ComboPooledDataSource getDataSource() throws Exception{
ComboPooledDataSource cpds = new ComboPooledDataSource();
cpds.setDriverClass( driver);
cpds.setJdbcUrl( url );
cpds.setUser(user);
cpds.setPassword(passwd);
cpds.setMinPoolSize(5);
cpds.setAcquireIncrement(5);
cpds.setMaxPoolSize(30);
cpds.setMaxIdleTime(60);
return cpds;
}
}
谢谢你给我了这个,但是我不明白这里面写的什么意思。刚学呢
