在WebWork中开启Spring支持是非常简单的,把最新版本的Spring的jar攑ֈ你的classpath?然后在webwork.properties里面讄如下选项:
webwork.objectFactory = spring (tng)
此时使用的类? com.opensymphony.webwork.spring.WebWorkSpringObjectFactory,也可以指定ؓ(f)其他SpringObjectFactory.
~省Spring的装配策略是 by name,可以修改webwork.properties改ؓ(f)其他方式,例如type,name,auto{这时所有对象都首先来用Spring来创?如果Spring没有创徏q些对象,WebWork?x)自己创些对? 然后,你需要在web.xml里面讄Spring的listener:
(tng) <listener>
(tng) (tng) (tng) (tng) (tng) <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
(tng) </listener> (tng)
Spring配置CZ
(tng)q时,你可以添加一个标准的Spring配置文g:WEB-INF/applicationContext.xml,举例如下:
<?xml version="1.0" encoding="UTF-8"?>
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "
http://www.springframework.org/dtd/spring-beans.dtd
">
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) <beans default-autowire="autodetect">
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) <bean id="personManager" class="com.acme.PersonManager"/>
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) ...
(tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) (tng) </beans>
使用Spring初始化Action
一般来?你在xwork.xml里面为每个Action指定c?当用SpringObjectFactory的时?如果按照上面的方法配|了(jin)), q意味着WebWork?x)首先请求Spring创徏q个Actionq按照缺省的自动装配{略讑֮依赖的属?SpringObjectFactoryq(sh)(x)调用所有bean的处理器来处理事?安全{方面的代理机制.不需要特D的讄Spring可以自动确?对大多数的应?q会(x)配置你的Action所需的服务和依赖,来达C的所有要?
(tng)我们强烈推荐你找CU声明的Ҏ(gu)来让spring知道该ؓ(f)你的Action提供什?q包括把你的Action里的属性命名ؓ(f)在Spring配子文g里定义的Bean的名字一?q样可以实现Z名字的自动装?q可以用JDK5的标注来声明事务和安全层需?如果你能扑ֈҎ(gu)让Spring知道你的Action需要什么而且不需要在applicationContext.xml里面q行外部配置的话,你就不需要在2个地方维护配|了(jin).
(tng)
然?有时你可能想要Spring来完全管理Bean.q是有实际意义的,例如,你如果想对你的Bean使用AOP或者Spring的相x(chng)?例如Acegi.Z(jin)辑ֈq个目的,你仅仅要做的是在xwork.xml里移除你的WebWork Action的类的属?然后在applicationContext.xml里面配置q个Bean.
(tng)
(tng)你的xwork.xml文g里面的action应该q样定义:
<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN" "
http://www.opensymphony.com/xwork/xwork-1.1.dtd
">
<xwork>
(tng) <include file="webwork-default.xml"/>
(tng) <package name="default" extends="webwork-default">
(tng) (tng) (tng) <action name="foo" class="foo">
(tng) (tng) (tng) (tng) (tng) <result>foo.ftl</result>
(tng) (tng) (tng) </action>
(tng) </package>
(tng) <package name="secure" namespace="/secure" extends="default">
(tng) (tng) (tng) <action name="bar" class="bar">
(tng) (tng) (tng) (tng) (tng) <result>bar.ftl</result>
(tng) (tng) (tng) </action>
(tng) </package>
</xwork>
Where you have a Spring bean defined in your applicationContext.xml named "bar". Note that the com.acme.Foo action did not need to be changed, because it can be autowired.
(你需要在你的applicationContext.xml里定义一个名字ؓ(f)"bar"的bean. 注意 com.acme.Foo不需要被改变,因ؓ(f)它是自动装配?)
(tng)C:q个不是必须?仅仅当你需要用Spring的拦截器或者IoC来修饰Action以便覆盖Webwork的缺省行为时,q才是必要的.要记住一?WebWork的Springl合?x)执行标准的IoC,使用你指定的自动装配{略,即你没有明第在Spring中映每个Action.所以通常你不需要做q个,但是知道怎么做对你是有好处的,如果你需要的?
