1.2 编写dao

package com.spring.domain;

public class Account {
    private String name;

    private Double money;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Double getMoney() {
        return money;
    }

    public void setMoney(Double money) {
        this.money = money;
    }

    @Override
    public String toString() {
        return "Account{" +
                "name='" + name + '\'' +
                ", money=" + money +
                '}';
    }
}

 

1.3 编写测试类

package com.spring.test;

import com.mchange.v2.c3p0.ComboPooledDataSource;
import org.junit.Test;
import org.springframework.jdbc.core.JdbcTemplate;


import java.beans.PropertyVetoException;

public class JdbcTemplateTest {

    @Test
    public void test() throws PropertyVetoException {
        ComboPooledDataSource comboPooledDataSource = new ComboPooledDataSource();
        comboPooledDataSource.setDriverClass("com.mysql.jdbc.Driver");
        comboPooledDataSource.setJdbcUrl("jdbc:mysql://localhost:3306/test?serverTimezone=UTC&characterEncoding=UTF-8");
        comboPooledDataSource.setUser("root");
        comboPooledDataSource.setPassword("root");
        JdbcTemplate jdbcTemplate = new JdbcTemplate();
        jdbcTemplate.setDataSource(comboPooledDataSource);
        int leon = jdbcTemplate.update("insert into account values(?,?)", "leon", 39);
        System.out.println(leon);

    }
}
