我是 struts 2 的新手,我正在做的是在 struts 2 中创建一个表单并在其他页面上显示输入的值。但是当我在 step1.jsp 页面上提交值时,它没有显示在 profileuplaoded.jsp
这是我在其上输入值 step1.jsp 的 jsp 页面
<%@ taglib uri="/struts-tags" prefix="s" %>
<h2>User Profile upload form</h2>
<s:form action="upload" method="post">
<s:textfield name="fname" label="First Name"></s:textfield>
<s:textfield name="lname" label="Last Name"></s:textfield>
<!-- <s:radio name="mstatus" label="Martial Status" list="{'Single','Married'}">
</s:radio><s:radio name="gender" label="Gender" list="{'male','female'}"></s:radio>-->
<s:submit value="upload profile" align="center"></s:submit>
</s:form>
这是我的另一个 jsp,我想在其上显示输入的值 profileuploaded.jsp
<%@ taglib uri="/struts-tags" prefix="p" %>
<h2>Profile uploaded sucessfully</h2>
First Name:<p:property value="fname"/><br/>
Last Name:<p:property value="lname"/><br/>
Martial status:<p:property value="mstatus"/><br/>
Gender:<p:property value="gender"/><br/>
这是我的java文件uploadprofile.java
package com.javapoint;
import com.opensymphony.xwork2.ActionSupport;
public class UploadProfile extends ActionSupport {
/**
*
*/
private static final long serialVersionUID = 1L;
private String fname;
private String lname;
//private String mstatus;
//private String gender;
public String getfname() {
System.out.println("inside getfname");
return fname;
}
public void setfname(String fname) {
System.out.println("inside getfname");
System.out.println("the firstname set is "+fname);
this.fname = fname;
}
public String getlname() {
return lname;
}
public void setlname(String lname) {
this.lname = "lname";
System.out.println("the lastname set is "+ lname);
}
/*public String getMstatus() {
return mstatus;
}
public void setMstatus(String mstatus) {
this.mstatus = mstatus;
}
public String getGender() {
return gender;
}
public void setGender(String gender) {
this.gender = gender;
}*/
public String execute()throws Exception{
System.out.println("inside execute");
if(fname!=null){
return "profileuploaded";
}else{
return "error";
}
}
}
这是我的 struts.xml
