Question

我是Struts的新手。我遇到了问题。我试图将JSP表单值填充到Action类中，但我没有在Action类中获取值。谁能告诉我什么是问题？这是我的JSP。

addEmployee.jsp

<a:form action="addEmployee">
<a:textfield name="eId" size="20" label="EmployeeID"/>
<a:textfield name="eName" size="20" label="EmployeeName"/>
<a:textfield name="eCity" size="20" label="EmployeeCity"/>
<a:submit value="ADD EMPLOYEE" ></a:submit>
</a:form>

我的动作类 - AddEmployeeAction.java

package com.action;

import com.opensymphony.xwork2.ActionSupport;

public class AddEmployeeAction extends ActionSupport{
/**
 * 
 */
private static final long serialVersionUID = 1L;
int eId;
String eName;
String eCity;


public AddEmployeeAction(){
}

@Override
public String execute() throws Exception{
    System.out.println("*******Execute*******"+eId+eName+eCity);
    return "success";

}
public int geteId() {
    return eId;
}

public void seteId(int eId) {
    this.eId = eId;
}

public String geteName() {
    return eName;
}

public void seteName(String eName) {
    this.eName = eName;
}

public String geteCity() {
    return eCity;
}

public void seteCity(String eCity) {
    this.eCity = eCity;
}

}

我的配置文件 - struts.xml

<struts>

<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />


<package name="default" extends="struts-default" namespace="/">
    <action name="addEmployee" class="com.action.AddEmployeeAction">
        <result name="success">/response.jsp</result>
        <result name="input">/addEmployee.jsp</result>
    </action>
 </package>
</struts>

你的getter和setter命名不正确;他们应该遵循JavaBean命名约定：

public String getEName() {
    return eName;
}

public void setEName(String eName) {
    this.eName = eName;
}

就个人而言，我要么：

更好地命名，例如empName，employeeName或
公开员工并在表单中使用employee.name等，或
使用ModelDriven<Employee>

不相关，但标签应该是人类可读的，例如“员工姓名”，而不是像骆驼一样的Java-esque字符串。
