Here I am trying into integrating Struts 2 with JSON ,jQuery and ajax It is calling to the action class but i am not getting json response. I have added all json plugin and json-defult in struts-xml

Ajax function 

function callajax() {
    alert(1);
    $.getJSON('edituser.action', function(data) {
        alert(data);
    });
}

Action class.

package com.hyva.accounts.master.useraccountsetup;

import com.opensymphony.xwork2.ActionSupport;

/**
 *
 * @author ranjeeth.g
 */
public class MasterUserSetUpActionEdit extends ActionSupport {

    private String username = "ranjith";
    private String password = "1234";
    private String fullname = "Ranjith";
    private String emailaddress = "Ranjith";
    private String telephone = "8762232246";

    @Override
    public String execute() {
//        System.out.println("session = " + session.isOpen());
        return "success";
    }

    public String getUsername() {
        return username;
    }

    public void setUsername(String username) {
        this.username = username;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getFullname() {
        return fullname;
    }

    public void setFullname(String fullname) {
        this.fullname = fullname;
    }

    public String getEmailaddress() {
        return emailaddress;
    }

    public void setEmailaddress(String emailaddress) {
        this.emailaddress = emailaddress;
    }

    public String getTelephone() {
        return telephone;
    }

    public void setTelephone(String telephone) {
        this.telephone = telephone;
    }
}

Struts-xml

            <result type="json"></result>
   </action>

1) 根据您的 struts2 版本从此处包含 json

2）您的包裹应扩展json-default如下

<package name="example1" extends="struts-default, json-default">
<action name="edituser" class="com.hyva.accounts.master.useraccountsetup.MasterUserSetUpActionEdit">
            <result type="json"></result>
   </action>
</package>

3）检查您的操作以获取 json 结果，例如地址 bas 中的操作名称 http://localhost:8080/edituser

它将显示对浏览器的 json 响应。

包括 Apache 的commons-lang-2.x.jar.

然后，由于 2.1.8 发生了重大变化，请注意，将 2.1.6 与 2.1.8 混合在一起是非常非常糟糕的。

对所有的 struts 库使用相同的版本。Struts-core、Struts-json、其他（如果有的话）（struts-spring-plugin、struts-config-browser-plugin、struts-junit-plugin 等）。除了 struts-jquery-plugin、frremarker 和 ognl（必须根据Struts 依赖项页面中指定的正确版本选择 btw ）。

然后，由于安全问题（和其他原因），尝试升级到最新版本（2.3.16.3）是根本。如果你要那样做，那么包括 Apachecommons-lang-2.x.jar和 Apache 的commons-lang3-3.x.jar（如果只有后者还不够，因为遗留代码）。由于它们在不同的包装中，因此它们可以共存。
