dwr学习笔记（和Hibernate、Spring等框架整合）一

 最近因为要学习dwr，我呢有个习惯，就是在学习即将结束的时候写点笔记，以便将来用的时候快速查阅！现将笔记整理如下：

我们做关联表的增加、删除、修改。

班级表(myclass)：id、name

学生表(student)：id、name、age、sex、birthday、class_id

一、与Hbiernate、Spring框架集成。

二、加入dwr插件。

 

1、新建工程demo

2、Add a new source folder。名字是conf。里面主要存放一下Hibernate和Sping配置文件。

3、在conf下新建applicationContext.xml、demo-service.xml、jdbc.properties、log4j.properties。四个文件。

其作用分别如下：

      3.1-->applicationContext.xml文件，既是Hbiernate的配置文件也是Spring的配置文件。

<?xml version="1.0" encoding="utf-8"?>
<beans default-autowire="byType"
	xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="

		http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
		http://www.springframework.org/schema/tx 
		http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

	<bean id="propertyConfigurer" 	class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="locations">
			<list>
				<value>classpath:jdbc.properties</value>
			</list>
		</property>
	</bean>
	<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
		<property name="driverClassName">
			<value>${jdbc.driverClassName}</value>
		</property>
		<property name="url">

		</property>
		<property name="username">
			<value>${jdbc.username}</value>
		</property>
		<property name="password">

		</property>
	</bean>

	<bean id="transactionManager"
		class="org.springframework.orm.hibernate3.HibernateTransactionManager">
		<property name="sessionFactory" ref="sessionFactory" />
	</bean>

	<bean id="jdbcTemplate"
		class="org.springframework.jdbc.core.JdbcTemplate">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
	</bean>

	<bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
		<property name="dataSource">
			<ref bean="dataSource" />
		</property>
		<property name="hibernateProperties">
			<props>
				<prop key="hibernate.dialect">
					org.hibernate.dialect.MySQLInnoDBDialect
				</prop><!--<prop key="hibernate.dialect">org.hibernate.dialect.Oracle9Dialect</prop>-->
				<prop key="hibernate.cache.use_query_cache">false</prop>
				<prop key="hibernate.show_sql">true</prop>
			</props>
		</property>
		<property name="mappingDirectoryLocations">
			<list>
				<value>
					classpath:/com/inspur/mydemo/domain/hbm/mysql
				</value>
			</list>
		</property>
	</bean>
</beans>

 

      （注意事项：1、beans里的标签库不能少。2、配置数据库表和java中的bean对象配置文件hbm的路径不能错）

      3.2-->demo-service.xml，这个主要是Sping的配置文件配置。

<?xml version="1.0" encoding="utf-8"?>
<beans default-autowire="byType"
	xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	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-2.0.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd">

	<import resource="applicationContext.xml" />

	<!-- service -->
	<bean id="classService"
		class="com.inspur.mydemo.service.impl.ClassServiceImpl"
		autowire="byType">
	</bean>
	<bean id="StudentService"
		class="com.inspur.mydemo.service.impl.StudentServiceImpl"
		autowire="byType">
	</bean>
	<!-- dwr -->
	<bean id="mydemoDwr" class="com.inspur.mydemo.dwr.MydemoDwr"
		autowire="byType">
	</bean>

</beans>

 

      3.3-->jdbc.properties，配置的是数据库链接。

# mysql-----------------
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/test?useUnicode=true&characterEncoding=GBK
jdbc.username=root
jdbc.password=root

 

      3.4-->log4j.properties，配置的是日志系统。

 

### set log levels - for more verbose logging change 'info' to 'debug' ##
log4j.rootLogger=info,stdout,A2

### direct log messages to stdout ###
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
