spring的配置文件怎么写

Answer 1

标准的Spring配置文件编写：

<?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-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"
default-autowire="byName" default-lazy-init="true">

<!-- 配置数据源 -->
<bean id="dataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName">
<value>com.mysql.jdbc.Driver</value>
</property>
<property name="url">
<value>
jdbc:mysql://localhost/ssh?characterEncoding=utf-8
</value>
</property>
<property name="username">
<value>root</value>
</property>
<property name="password">
<value>123</value>
</property>
</bean>

<!--配置SessionFactory -->
<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="mappingResources">
<list>
<value>com/ssh/pojo/User.hbm.xml</value>
</list>
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>

<!-- 事务管理 -->
<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>

<!-- hibernateTemplate -->
<bean id="hibernateTemplate"
class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory">
<ref bean="sessionFactory" />
</property>
</bean>

<!-- 配置数据持久层 -->
<bean id="userDao"
class="com.ssh.dao.impl.UserDaoImpl">
<property name="hibernateTemplate" ref="hibernateTemplate"></property>
</bean>

<!-- 配置业务逻辑层 -->
<bean id="userService"
class="com.ssh.service.impl.UserServiceImpl">
<property name="userDao" ref="userDao"></property>
</bean>

<!-- 配置控制层 -->
<bean id="UserAction"
class="com.ssh.action.UserAction" scope="prototype">
<property name="userService" ref="userService"></property>
</bean>
<!-- 配置pojo -->
<bean id="User" class="com.ssh.pojo.User" scope="prototype"/>
</beans>

<?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-2.0.xsd">

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
<property name="url" value="jdbc:mysql://localhost:3306/yonghu"></property>
<property name="username" value="root"></property>
<property name="password" value="root"></property>
<property name="maxActive" value="100"></property>
<property name="maxIdle" value="30"></property>
<property name="maxWait" value="500"></property>
<property name="defaultAutoCommit" value="true"></property>
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
<property name="mappingResources">
<list>
<value>beans/Users.hbm.xml</value>
</list>
</property>
</bean>
<bean id="userDao" class="DAOImpl.userDaoImpl">
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>
<bean id="userService" class="ServiceImpl.userServiceImpl">
<property name="userDao" ref="userDao"></property>
<property name="sessionFactory">
<ref bean="sessionFactory"/>
</property>
</bean>
<bean id="saveUser" class="actions.saveUser">
<property name="userService" ref="userService"></property>
</bean>
</beans>

就是action层调用service层 service层调用dao层 dao层调用sessionFactory sessionFactory调用datasource
