spring和jdbc结合的一个小例子

1.新建一个SpringJdbc的maven项目。
2.引入需要的jar包的依赖

<span style="white-space:pre">		</span><dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>4.8</version>
			<scope>test</scope>
		</dependency>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-core</artifactId>
			<version>4.2.5.RELEASE</version>
		</dependency>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-context</artifactId>
			<version>4.2.5.RELEASE</version>
		</dependency>

		<dependency>
			<groupId>commons-logging</groupId>
			<artifactId>commons-logging</artifactId>
			<version>1.2</version>
		</dependency>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-aop</artifactId>
			<version>4.2.5.RELEASE</version>
		</dependency>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-beans</artifactId>
			<version>4.2.5.RELEASE</version>
		</dependency>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-expression</artifactId>
			<version>4.2.5.RELEASE</version>
		</dependency>

		<dependency>
			<groupId>org.aspectj</groupId>
			<artifactId>aspectjweaver</artifactId>
			<version>1.8.8</version>
		</dependency>

		<dependency>
			<groupId>org.aspectj</groupId>
			<artifactId>aspectjrt</artifactId>
			<version>1.8.8</version>
		</dependency>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-jdbc</artifactId>
			<version>4.2.5.RELEASE</version>
		</dependency>
		
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<version>5.1.38</version>
		</dependency>

3.在src/java/resources下面新建一个jdbcApplication.xml

<?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:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd  
                http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd  
                http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.5.xsd  
                http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">
</beans>

4.新建一个接口，JdbcService（这里就不使用dao层了），里面有个save方法

5.写个实现类，JdbcServiceImpl（这里首先要建好数据库），然后注入JbcTemplate

6.在xml中配置相关资源

①配置dataSource，这里使用的是Spring提供的DriverManagerDataSource

	<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<list>
				<value>classpath:resources.properties</value>
			</list>
		</property>
	</bean>

	<bean id="dataSource"
		class="org.springframework.jdbc.datasource.DriverManagerDataSource">
		<property name="driverClassName" value="${driverClassName}"></property>
		<property name="url" value="${url}"></property>
		<property name="username" value="${username}"></property>
		<property name="password" value="${password}"></property>
	</bean>

这种是使用读取配置文件获取信息的方式，也可以直接写这些参数

resources.properties为

<span style="white-space:pre">	</span>driverClassName:com.mysql.jdbc.Driver
<span style="white-space:pre">	</span>url:jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8
<span style="white-space:pre">	</span>username:root
<span style="white-space:pre">	</span>password:root

②配置jdbcTemplate

<span style="white-space:pre">	</span><bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
		<property name="dataSource" ref="dataSource"></property>
	</bean>

③配置jdbcService

	<bean id="jdbcService" class="com.qiao.springjdbc.JdbcServiceImpl">
		<property name="jdbcTemplate" ref="jdbcTemplate"></property>
	</bean>

7.写测试类

运行后，数据库会多出一天数据

就表示成功了。
