JSF+Spring整合原理？

Question

JSF+Spring整合是什么原理？Struts集合Spring有三种方法，JSF呢？

Answer 1

Spring 包括两方面 IOC和AOP，
IOC用的比较多，达到用配置文件控制对象生成，
目的是达到在不修改代码的情况下，就可以进行功能扩展。AOP 面向方面编程， 控制调用方法前后执行，对数据库访问时候的事务处理可以用。

去搜索一下, JSF提供了一些扩展接口VaiableResoler, 把ManageBean指到Spring的bean<faces-config> <!--
<lifecycle>
<phase-listener>
   xxx.xxx.xxx.PhaseListener
</phase-listener>
</lifecycle> 
 --> <application>
<variable-resolver>
org.springframework.web.jsf.DelegatingVariableResolver
</variable-resolver>
<action-listener>xxx.xx.x.ControlActionListener</action-listener>
</application> <managed-bean>
        <managed-bean-name>reportMetadata</managed-bean-name>
        <managed-bean-class>xxxx..PresentReportMetadata</managed-bean-class>
        <managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>reportMetaDataBO</property-name>
<value>#{reportMetadataBO}</value>
</managed-property>
<managed-property>
<property-name>productDao</property-name>
<value>#{productDao}</value>
</managed-property>
<managed-property>
<property-name>rrdDao</property-name>
<value>#{rrdDao}</value>
</managed-property>
<managed-property>
<property-name>languageDao</property-name>
<value>#{languageDao}</value>
</managed-property>
<managed-property>
<property-name>converter</property-name>
<value>#{j2JSConverter}</value>
</managed-property>
<managed-property>
<property-name>servicesManager</property-name>
<value>#{servicesManager}</value>
</managed-property>
    </managed-bean>

Answer 3

JSF与Struts不一样.
JSF里面自带有依赖注入功能.
要与Spring整合,只需引用Spring配置文件里面的beanid名字就行了.
不过在JSF配置文件里面引用spring实例的格式不是${} 而是#{},
然后在JSF配置文件里面还要配置:
<application>
<message-bundle>messages-override</message-bundle>
<variable-resolver>
org.springframework.web.jsf.DelegatingVariableResolver
</variable-resolver>
</application>
举个例子:Spring配置文件application.xml
<?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="continent" class="cn.hana.pojos.Continent"></bean>
    <bean id="country" class="cn.hana.pojos.Country"></bean>
  <bean id="city" class="cn.hana.pojos.City"></bean>
  <bean id="company" class="cn.hana.pojos.Company"></bean>
  <bean id="line" class="cn.hana.pojos.Lines"></bean>
  <bean id="service" class="cn.hana.pojos.Service"></bean>
  <bean id="port" class="cn.hana.pojos.Port"></bean>
 
  <bean id="vayage" class="cn.hana.pojos.Voyage"></bean>
  <bean id="vayageschedule" class="cn.hana.pojos.Voyageschedule"></bean>
  <bean id="vessel" class="cn.hana.pojos.Vessel"></bean>
</beans>JSF配置文件中的:
<?xml version='1.0' encoding='UTF-8'?>
