spring事物源码分析篇二：测试实例的编写

创建数据库表

CREATE TABLE `test_user` (

  `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,

  `testName` varchar(20) DEFAULT NULL,

  `age` bigint(20) DEFAULT NULL,

  `sex` varchar(20) DEFAULT NULL,

  PRIMARY KEY (`id`)

) ENGINE=InnoDB AUTO_INCREMENT=12 DEFAULT CHARSET=utf8 COMMENT='测试用户表';

创建实体：

package com.spring.jdbc.model;

public class User {
    
    private int id;
    
    
    private String testName;
    
    
    private String sex;
    
    private int age;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }


    public String getTestName() {
        return testName;
    }

    public void setTestName(String testName) {
        this.testName = testName;
    }

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

}

创建Mapper类：

package com.spring.jdbc.mapper;

import java.sql.ResultSet;
import java.sql.SQLException;

import org.springframework.jdbc.core.RowMapper;

import com.spring.jdbc.model.User;


public class UserRowMapper implements RowMapper {

    @Override
    public Object mapRow(ResultSet rs, int rowNum) throws SQLException {
        User person = new User();
        person.setId(rs.getInt("id"));
        person.setAge(rs.getInt("age"));
        person.setTestName(rs.getString("testName"));
        person.setSex(rs.getString("sex"));
        
        return person;
    }

}

创建service接口：

package com.spring.jdbc.service;

import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;

import com.spring.jdbc.model.User;

@Transactional(propagation = Propagation.REQUIRED)
public interface UserService {

    public void save(User user) throws Exception;
    
}

创建service接口实现类：

package com.spring.jdbc.service.impl;

import javax.sql.DataSource;

import org.springframework.jdbc.core.JdbcTemplate;

import com.spring.jdbc.model.User;
import com.spring.jdbc.service.UserService;

public class UserServiceImpl implements UserService {
    private JdbcTemplate  template;
    
    public void setDataSource(DataSource dataSource){
        this.template = new JdbcTemplate(dataSource);
        
    }
    
    @Override
    public void save(User user) throws Exception {
        
        template.update("insert into test_user(testName,age,sex) values(?,?,?)",
                new Object[]{user.getTestName(),user.getAge(),user.getSex()},new int[]{java.sql.Types.VARCHAR,java.sql.Types.INTEGER,java.sql.Types.VARCHAR}
                );
        
        throw new Exception();

    }

}

编写配置文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd
    http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd">

    <!-- http://www.cnblogs.com/adolfmc/archive/2013/01/22/2872298.html -->
    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver" />
        <property name="url" value="jdbc:mysql://localhost:3306/spring"/>
        <property name="username" value="root" />
        <property name="password" value="root" />
        <property name="initialSize" value="1" />
        <property name="minIdle" value="1" />
        <property name="maxActive" value="300" />
        <property name="maxIdle" value="2" />
    </bean>


    <bean id="userService" class="com.spring.jdbc.service.impl.UserServiceImpl">
        <property name="dataSource" ref="dataSource" />
        
    </bean>


    <!-- 事务管理器 -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager" >
        <property name="dataSource" ref="dataSource" />
    </bean>

    <!-- 开启事务注解驱动 -->
    <tx:annotation-driven transaction-manager="transactionManager" />
    
    
</beans>

编写测试类：

package com.spring.jdbc;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.spring.jdbc.model.User;
import com.spring.jdbc.service.UserService;

public class SpringJdbcTest {

    public static void main(String[] args) throws Exception {
        ClassPathXmlApplicationContext applicationContext = new ClassPathXmlApplicationContext("spring-jdbc.xml");//BeanDefination的解析注册，代理对象的生成        
        UserService  userService =   (UserService)applicationContext.getBean("userService");
        User user = new User();
        user.setAge(24);
        user.setTestName("测试");
        user.setSex("man");
        userService.save(user);
    
    }

}

运行结果：
