Spring-JdbcTemplate(注入到spring容器)-02

1.导入spring-jdbc和spring-tx坐标

 <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.13</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-test</artifactId>
      <version>5.0.5.RELEASE</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context</artifactId>
      <version>5.0.5.RELEASE</version>
    </dependency>
    <dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <version>8.0.19</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
      <version>5.0.9.RELEASE</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-tx</artifactId>
      <version>5.0.9.RELEASE</version>
    </dependency>
    <dependency>
      <groupId>com.mchange</groupId>
      <artifactId>c3p0</artifactId>
      <version>0.9.5.2</version>
    </dependency>

2.创建数据库表和实体类

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;
    }
}

3.创建数据库表

4.配置jdbc.properties资源文件

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?serverTimezone=UTC
jdbc.username=root
jdbc.password=hao20001010

5.将数据源和模板交给到spring管理

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context  http://www.springframework.org/schema/context/spring-context.xsd">
<!--加载资源文件-->
    <context:property-placeholder location="jdbc.properties"/>
<!--    配置数据域对象-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"/>
        <property name="jdbcUrl" value="${jdbc.url}"/>
        <property name="user" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
<!--    Jdbc模板对象-->
    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource" ref="dataSource"/>
    </bean>
</beans>

6.测试

 @Test
    //测试spring产生的jdbcTemplate对象
    public void test2(){
        ApplicationContext app=new ClassPathXmlApplicationContext("applicationContext.xml");
        JdbcTemplate jdbcTemplate = app.getBean(JdbcTemplate.class);
        int row=jdbcTemplate.update("insert into account values(?,?)","tom",2000);
        System.out.println(row);
    }

结果：1
