jsf运行源代码 (MyEclipse6.5环境)
jsf的简单演示
摘自百度文库 搜 jsf入门 就能找到原文 但愿一直都在.上面有详细解释...
时间匆忙,我先记下我运行起来的jsf...
1 加载相关架包.这里我是通过MyEclipse自带的jsf加载的.
2 修改web.xml文件 最好不要全部覆盖,将web-app里面的部分拷入替换原来内容.
3 facse-config.xml与web.xml在同一路径.内容修改如下:
4 后台的java文件如下:
5 两个jsp文件放在和index.jsp同一目录.
hello.jsp的内容:
goodbye.jsp内容:
全部完成后网址运行地址:

1 加载相关架包.这里我是通过MyEclipse自带的jsf加载的.
2 修改web.xml文件 最好不要全部覆盖,将web-app里面的部分拷入替换原来内容.
<?xml version="1.0" encoding="UTF-8"?> <web-app> <display-name>hello world</display-name> <description>Welcome to JavaServer Faces.</description> <servlet> <servlet-name>Faces Servlet</servlet-name> <servlet-class>javax.faces.webapp.FacesServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>Faces Servlet</servlet-name> <url-pattern>/faces/*</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>faces/hello.jsp</welcome-file> </welcome-file-list> </web-app>
3 facse-config.xml与web.xml在同一路径.内容修改如下:
<?xml version='1.0' encoding='UTF-8'?> <faces-config xmlns="http://java.sun.com/xml/ns/javaee" 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_1_2.xsd" version="1.2"> <managed-bean> <description>The one and only HelloBean.</description> <managed-bean-name>helloBean</managed-bean-name> <managed-bean-class>org.jia.hello.HelloBean</managed-bean-class> <managed-bean-scope>session</managed-bean-scope> </managed-bean> <navigation-rule> <description>Navigation from the hello page.</description> <from-view-id>/hello.jsp</from-view-id> <navigation-case> <from-outcome>success</from-outcome> <to-view-id>/goodbye.jsp</to-view-id> </navigation-case> </navigation-rule> </faces-config>
4 后台的java文件如下:
package org.jia.hello;
import javax.faces.application.Application;
import javax.faces.component.html.HtmlOutputText;
import javax.faces.component.html.HtmlPanelGrid;
import javax.faces.context.FacesContext;
import javax.faces.event.ActionEvent;
import java.util.List;
public class HelloBean {
private int numControls;
private HtmlPanelGrid controlPanel;
public int getNumControls() {
return numControls;
}
public void setNumControls(int numControls) {
this.numControls = numControls;
}
public HtmlPanelGrid getControlPanel() {
return controlPanel;
}
public void setControlPanel(HtmlPanelGrid controlPanel) {
this.controlPanel = controlPanel;
}
public void addControls(ActionEvent actionEvent) {
Application application = FacesContext.getCurrentInstance().getApplication();
List children = controlPanel.getChildren();
System.out.println("children==="+children);
children.clear();
for (int count = 1; count <= numControls; count++) {
HtmlOutputText output = (HtmlOutputText) application.createComponent(HtmlOutputText.COMPONENT_TYPE);
output.setValue(" " + count + " ");
output.setStyle("color: red");
children.add(output);
}
}
public String goodbye() {
return "success";
}
}
5 两个jsp文件放在和index.jsp同一目录.
