dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.3.12.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>4.3.12.RELEASE</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.38</version> </dependency> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.2</version> </dependency>

编写目标类：

import org.springframework.jdbc.core.JdbcTemplate;

public class UserDao {
    private JdbcTemplate jdbcTemplate;
    public void setJdbcTemplate(JdbcTemplate jdbcTemplate) {
        this.jdbcTemplate = jdbcTemplate;
    }

    public void insert(){
        String sql="insert into user (name,deptid) values (?,?)";
        jdbcTemplate.update(sql, new Object[]{"caoyc",3});
    }
}

配置xml配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
         <property name="user" value="root"></property>
        <property name="password" value="123456"></property>
         <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
         <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test"></property>
     </bean>
     <!--配置jdbcTemplate对象，并为类中的dataSource属性注入值 -->
     <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
         <property name="dataSource" ref="dataSource"></property>
     </bean>
     <!--配置userDao对象，并为类中的属性注入值 -->
     <bean id="userDao" class="com.jdbcTemplate.UserDao">
         <property name="jdbcTemplate" ref="jdbcTemplate"/>
     </bean>
</beans>

编写测试代码：

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {
    public static void main(String[] args) {
        ApplicationContext context=new ClassPathXmlApplicationContext("bean5.xml");
        UserDao userDao= (UserDao) context.getBean("userDao");
        userDao.insert();
    }
}

运行结果：数据正常入库。
