URL字符串来传递参数

在jsf中使用URL字符串来传递参数,简单例子代码如下

假设url如下:

http://localhost:8080/test/urlTest.faces?id=123

urlTest.jsp

<%@ page language="java" pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
<%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
<body>
<f:view>

  This is my url Test page. <br>
   
   <h:outputText value="#{param['id']}" />
   <br>

<h:outputText value="#{urlTest.id}"/>
</f:view>
</body>
</html>

==================================================================

UrlTest.java

import javax.faces.context.FacesContext;

public class UrlTest {
private String id = "";

public String getId() {

   FacesContext fc = FacesContext.getCurrentInstance();
   id = (String) fc.getExternalContext().getRequestParameterMap().get("id");
   System.out.println("---------------"+id);
  return id;
}

public void setId(String id) {
this.id = id;
}

}

==================================================================
faces-config.xml

<managed-bean>
  <description>url test Bean</description>
  <managed-bean-name>urlTest</managed-bean-name>
  <managed-bean-class>test.UrlTest</managed-bean-class>
  <managed-bean-scope>request</managed-bean-scope>
</managed-bean>

ok 到这里就差不多了,输入http://localhost:8080/test/urlTest.faces?id=123测试吧!~
