JSF2.0与Spring3集成

2011-11-20 15:26 531 查看

同以前的JSF1.2与Spring2.5集成类似，只是有一些类名和默认配置的变化。

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<servlet>

</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>

</web-app>

Faces-config.xml

<?xml version="1.0" encoding="UTF-8"?>
<faces-config version="2.0" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xi="http://www.w3.org/2001/XInclude" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-facesconfig_2_0.xsd"> 
<application>
<el-resolver>org.springframework.web.jsf.el.SpringBeanFacesELResolver</el-resolver>
</application>
</faces-config>

JSF1.2和1.2以前是加入

<variable-resolver>org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver>

Spring
的配置文件就正常配置就可以了

ApplicationContext.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" xmlns:context="http://www.springframework.org/schema/context"
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-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd"> 
<!-- 自动扫描组件 -->
<context:component-scan base-package="org.gui.jsf20" />
</beans>

服务层组件：

package org.gui.jsf20.service.impl;

import org.gui.jsf20.service.HelloService;
import org.springframework.stereotype.Service;

@Service("helloService")
public class HelloServiceImpl implements HelloService {

public HelloServiceImpl() {
System.out.println("Init helloService bean...");
}

public void sayHello(String words) {
System.out.println("You Say: " + words);
}

}

Backing Bean:

package org.gui.jsf20.form;

import javax.annotation.Resource;

import org.gui.jsf20.service.HelloService;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

@Controller("helloBean") @Scope("session")
public class HelloBean {
private String words;
private String result;

@Resource(name="helloService")
private HelloService helloService;

// Actions
public void doSayWords() {
helloService.sayHello(words);
result = "Are you Say \"" + words + "\"";
}

// Setters & Getters
public String getWords() {
return words;
}

public void setWords(String words) {
this.words = words;
}

public String getResult() {
return result;
}
public void setResult(String result) {
this.result = result;
}
}
