Struts2 JSONObject的使用

一、jar包

使用之前必须引入所须要的jar包,这里包含Struts2和JSONObject各自所必须的

Struts2:

commons-fileupload-1.2.1.jar
commons-io-1.3.2.jar
commons-lang-2.3.jar
commons-logging-1.0.4.jar
freemarker-2.3.13.jar
ognl-2.6.11.jar
struts2-core-2.1.6.jar
xwork-2.1.2.jar

JSONObject:

commons-beanutils-1.7.0.jar
commons-collections-3.2.jar
ezmorph-1.0.3.jar
json-lib-2.1.jar

PS: 本例Struts2版本号为2.1.6,以上全部jar包在struts-2.1.6\lib中都能够找到,

假设以上jar包是东拼西凑的特别是JSONObject,有可能会因jar包兼容性问题而报错。

二、前台代码

<body>

	<form id="myform">

		<table>

			<tr>

				<td>姓名:</td>

				<td> <input type="text" name="name" /> </td>

			</tr>

			<tr>

				<td>性别:</td>

				<td>

					<input type="radio" name="sex" value="1"> 男

					<input type="radio" name="sex" value="0"> 女

				</td>

			</tr>

			<tr>

				<td>年龄:</td>

				<td>

					<select name="age">

						<option value="20">20</option>

						<option value="21">21</option>

						<option value="22">22</option>

					</select>

				</td>

			</tr>

			<tr>

				<td colspan="2">

					<input type="button" id="ajaxBtn" value="提交" />

				</td>

			</tr>

		</table>

	</form>

	<div id="msg"></div>

</body>

<script type="text/javascript">

	$(function() {

		$("#ajaxBtn").click(function() {

			var params = $("#myform").serialize();

			$.ajax( {

				type : "POST",

				dataType: "json",

				url : "RegisterAction.action",

				data : params,

				success : function(msg) {

					if(msg.success == true){

						$("#msg").html("您提交的信息为,姓名: "+msg.name+

						", 性别："+msg.sex+", 年龄："+msg.age);

						alert("success");

					}else{

						alert("error");

					}

				},

				error : function(){

					alert("error");

				}

			});

		})

	})

</script>

三、后台

import java.io.IOException;

import java.io.PrintWriter;

import javax.servlet.http.HttpServletResponse;

import net.sf.json.JSONObject;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionContext;

public class RegisterAction {

	private String name;

	private String sex;

	private String age;

	public String register() {

		ActionContext ac = ActionContext.getContext();

		HttpServletResponse response = (HttpServletResponse) ac.get(ServletActionContext.HTTP_RESPONSE);

		response.setCharacterEncoding("utf-8");

		PrintWriter out;

		try {

			out = response.getWriter();

			JSONObject json=new JSONObject();

			json.put("success", true);

			json.put("name", name);

			json.put("sex", sex==null?"未知":("1".equals(sex)?"男":"女"));

			json.put("age", age);

			out.write(json.toString());

			out.flush();

			out.close();

		} catch (IOException e) {

			e.printStackTrace();

		}

		return null;

	}

	public String getName() {

		return name;

	}

	public void setName(String name) {

		this.name = name;

	}

	public String getSex() {

		return sex;

	}

	public void setSex(String sex) {

		this.sex = sex;

	}

	public String getAge() {

		return age;

	}

	public void setAge(String age) {

		this.age = age;

	}

}

四、Struts配置

<struts>

	<package name="build" extends="struts-default">

		<action name="RegisterAction" method="register" class="com.home.RegisterAction">

		</action>

	</package>

</struts>

例如以下图：

watermark/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvaXRteWhvbWUxOTkw/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast" alt="" />
