创建MyJsfAction.java
package com.dw.action;
import javax.faces.event.ValueChangeEvent;
public class MyJsfAction {
private String type;
public String getType() {
return type;
}
public void setType(String type) {
this.type = type;
}
// 定义监听值改变的方法
public void selectType(ValueChangeEvent event){
String nameTemp = (String)event.getNewValue();
if("JAVA".equals(nameTemp)){
type = "JAVA";
}else{
type = "C";
}
}
public String gourl(){
return type;
}
