spring连接数据库的两种方式

1，将仿问数据库连接的住处放到spring.xml中

<?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"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.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">

//连接mysql数据库

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"

destroy-method="close" >

<property name="driverClassName" value="com.mysql.jdbc.Driver">

</property>

<property name="url" value="jdbc:mysql://192.168.1.3:3306/mlxcdb">

</property>

<property name="username" value="root"></property>

<property name="password" value="mysql"></property>

</bean>

2，将仿问连接数据库连接的相关驱动信息放到jdbc.properties配置文件中

1. <!-- 使用属性文件配置数据源 -->  
2.  <bean id="propertyPlaceholderConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">  
3.     <property name="location" value="jdbc.properties"/>  
4.  </bean>  
5.  <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource" destroy-method="close">  
6.     <property name="driverClassName" value="${jdbc.driverClassName}"/>  
7.     <property name="url" value="${jdbc.url}"/>  
8.     <property name="username" value="${jdbc.username}"/>  
9.     <property name="password" value="${jdbc.password}"/>  
10.  </bean>  

//连接mysql数据库

jdbc.driverClassName=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://192.168.1.3:3306/mlxcdb

jdbc.username=root

jdbc.password=mysql
