Spring JdbcTemplate开发

 

 

JdbcTemplate开发步骤

①导入spring-jdbc和spring-tx坐标

在pom.xml中

 <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>5.0.5.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-tx</artifactId>
            <version>5.0.5.RELEASE</version>
        </dependency>

 

 

②创建数据库表和实体

package com.wjb.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 +
                '}';
    }
}

 

③创建JdbcTemplate对象，执行数据库操作

package com.wjb.test;

import com.mchange.v2.c3p0.ComboPooledDataSource;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jdbc.core.JdbcTemplate;

import java.beans.PropertyVetoException;

public class JdbcTemplateTest {

    @Test //spring产生jdbcTemplate对象
    public void test2() throws PropertyVetoException {
        ApplicationContext app = new ClassPathXmlApplicationContext("applicationContext.xml");
        JdbcTemplate jdbcTemplate = app.getBean(JdbcTemplate.class);
        jdbcTemplate.update("insert into account values (?,?) ", "zhangsan", 10000);
    }


    //测试jdbc模板开发步骤
    @Test
    public void test1() throws PropertyVetoException {
        //创建数据源对象
        ComboPooledDataSource dataSource = new ComboPooledDataSource();
        dataSource.setDriverClass("com.mysql.cj.jdbc.Driver");
        dataSource.setJdbcUrl("jdbc:mysql://localhost:3306/mybatis");
        dataSource.setUser("root");
        dataSource.setPassword("1767737316.");
        JdbcTemplate jdbcTemplate = new JdbcTemplate();
        jdbcTemplate.setDataSource(dataSource);

        //执行操作
        int row = jdbcTemplate.update("insert into account values (?,?) ", "tom", 5000);
        System.out.println(row);
    }
}
