最近好久没有发帖了，有点懒了(*^__^*)

最近刚做完一个 jsf的小例子，麻雀虽小，但是五脏俱全。下面我就把 它贴出来，具体的配置文件可以看 附件


下面我贴的都是配置中的一部分，都是需要注意的地方

1： web。xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.4" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

</context-param>
<context-param>
<param-name>log4jConfigLocation1</param-name>
<param-value>WEB-INF\classes\log4j.properties</param-value>

<!-- spring 监听器 -->

<!-- 配置 jsf -->

</servlet>

<servlet-mapping>
<servlet-name>FacesServlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
</web-app>


2：face-config.xml


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE faces-config PUBLIC "-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN" "http://java.sun.com/dtd/web-facesconfig_1_1.dtd">

<faces-config>

<managed-bean>
<managed-bean-name>addUser</managed-bean-name>
<managed-bean-class>com.rain.ralf.web.addUserBean</managed-bean-class>
<managed-bean-scope>request</managed-bean-scope>
<managed-property>
<property-name>userServiecs</property-name>
<value>#{userServiecs}</value>
</managed-property>
</managed-bean>






<navigation-rule>
<description>add user</description>
<from-view-id>/pages/addUser.jsp</from-view-id>
<navigation-case>
<from-outcome>sucess</from-outcome>
<to-view-id>/pages/Sucess.jsp</to-view-id>
</navigation-case>
</navigation-rule>
</navigation-rule>



<!-- 写在最后 用sprig的变量解析器代替jsf的变量解析器-->
<application>
<variable-resolver>org.springframework.web.jsf.DelegatingVariableResolver</variable-resolver>
</application>




</faces-config>

这里需要注意红色部分的地方，其实jsf本身就使用的ioc的思想，所以通过红色部分你可以直接在代码中直接 使用 service对象 。例如在 com.rain.ralf.web.addUserBean这个backbean中使用业务层的对象


public class addUserBean {

private UserService userServiecs;
public void setUserServiecs(UserService userServices) {
this.userServiecs = userServices;
}

public String addUser() {


try {
userServiecs.insertUserServices(uv);
return "sucess";
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
return null;
}
}

}

这样红色字体的 userServiecs对象就能直接使用了 ，其他的配置文件可以参考附件
