dwr+Spring的容易配置应用

dwr+Spring的简单配置应用
一、首先把下载的dwr和spring，proxool用到的包放到工程的/WEB-INF/lib目录下
二、
1.web.xml配置
注意servlet和其他的放在一起，servlet-mapping放在一起。

<servlet>
 <servlet-name>dwr-invoker</servlet-name>
 <servlet-class>
  org.directwebremoting.servlet.DwrServlet
 </servlet-class>
 <init-param>
  <param-name>initApplicationScopeCreatorsAtStartup</param-name>
  <param-value>true</param-value>
 </init-param>
 <init-param>
 	<param-name>crossDomainSessionSecurity</param-name>
 	<param-value>false</param-value>
 </init-param>
 <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
 <servlet-name>dwr-invoker</servlet-name>
 <url-pattern>/dwr/*</url-pattern>
</servlet-mapping>

2.proxool.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<proxool-config>
	<proxool>
		<alias>testdb</alias>
		<driver-url>
			jdbc:oracle:thin@IP:1521:test
		</driver-url>
		<driver-class>oracle.jdbc.driver.OracleDriver</driver-class>
		<driver-porperties>
			<property name="user" value="test" />
			<property name="password" value="test" />
		</driver-properties>
		<maximum-connection-lifetime>14400000</maximum-connection-lifetime>
		<maximum-active-time>600000</maximum-active-time>
		<minimum-connection-count>5</minimum-connection-count>
		<maximum-connection-count>200</maximum-connection-count>
		<houser-keeping-sleep-time>900000</house-keeping-sleep-time>
		<house-keeping-test-sql>
			SELECT CURRENT_DATE FORM DUAL
		</house-keeping-test-sql>
		<trace>true</trace>
	</proxool>
</proxool-config>

3.applicationContext-jdbc.xml的配置

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING/DTD BEAN//EN"
		"http://www/springframework.org/dtd/spring-beans.dtd">
<beans>
	<bean id="dataSource"
			class="org.springframework.jdbc.datasource.DriverManageDataSource">
			<property name="driverClassName">
				<value>org.logicalcobwebs.proxool.ProxoolDriver</value>
			</property>
			<property name="url">
				<value>proxool.tesddb</value>
<!--和proxool.xml中的<alias>中间的名一致-->
			</property>
	</bean>
	<bean id="transactionManager"
			class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
			<property name="dataSource" ref="dataSource" />
	</bean>
	<bean id="dwrTestService" class="service接口全路径">
		<property name="transactionManager" ref="transactionManager" />
		<property name="dataSource" ref="dataSource" />
	</bean>
</beans>

4.dwr.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN"
		"http://getahead.org/dwr/dwr2.0.dtd">
<dwr>
	<allow>
		<create creator="spring" javascript="dwr_test_service">
			<param name="beanName" value="dwrTestService" /><！--value值和上面service接口配置中的id名相同-->
		</create>
		<!-- 
			如果用到form或者domain需要写下面的
		-->
		<!--
			<convert match="包名到完整的类名" converter="bean" />
		-->
	</allow>
</dwr>

5.jsp页面

//引用dwr的js
<script type="text/javascript" src="/dwr/engine.js"></script>
<script type="text/javascript" src="/dwr/util.js"></script>
<script type="text/javascript" src="/dwr/interface/dwr_test_service.js"></script>
<script type="text/javascript">
function test() {
  dwr_test_service.testMethod(callBack);
}
// 回调函数
function callBack(){
}
</script>
