XML
1、引入dom4j-2.0.0.jar
2、引入jquery-1.8.2.js
3、新建common.js
getInfo = function(){ $.post("getXmlAction.action",{name:$('#name').val()},function(ret,status){ if("success" == status) var id = $(ret).find("id").text(); var age = $(ret).find("age").text(); var address = $(ret).find("address").text(); var name = $(ret).find("name").text(); var html = "<table>" + "<tr>" + "<th>" +id+age+address+name "</th>"+ "</tr>" + "</table>" $('body table:eq(0)').remove(); $('#xmlbody').append(html); }); }
getJson = function(){
$.post("getJsonAction.action",{name:$('#name').val()},function(ret,status){
if("success" == status){
}
});
}
4、新建xmlTest.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <script type="text/javascript" src="js/jquery-1.8.2.js"></script> <script type="text/javascript" src="scripts/common.js"></script> </head> <body id="xmlbody"> <select id="name"> <option value="james" selected="selected">james</option> <option value="currey">currey</option> </select> <input type="button" value="getInfo" onclick="getInfo();"/> </body> </html>
5、修改struts.xml文件
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts> <package name="testSSH" extends="struts-default"> <action name="getXmlAction" class="com.test.action.xml.GetXmlAction"> </action> </package> </struts>
6、新建GetXmlAction.java
package com.test.action.xml; import java.io.PrintWriter; import javax.servlet.http.HttpServletResponse; import org.apache.struts2.ServletActionContext; import org.dom4j.*; import org.dom4j.io.*; import com.opensymphony.xwork2.ActionSupport; public class GetXmlAction extends ActionSupport { private static final long serialVersionUID = 1L; private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } @Override public String execute() throws Exception { person person1 = new person(); person1.setAge(11); person1.setName("james"); person1.setId(1); person1.setAddress("beijing"); person person2 = new person(); person2.setId(2); person2.setAddress("shanghai"); person2.setAge(12); person2.setName("currey"); //创建 xml 对象 Document document = DocumentHelper.createDocument(); //创建根元素 Element rootElement = document.addElement("users"); Element userElement = rootElement.addElement("user"); Element idElement = userElement.addElement("Id"); Element ageElement = userElement.addElement("age"); Element addressElement = userElement.addElement("address"); Element nameElement = userElement.addElement("name"); if("james".equals(this.name)){ idElement.setText(person1.getId()+""); ageElement.setText(person1.getAge()+""); addressElement.setText(person1.getAddress()); nameElement.setText(person1.getName()); }else{ idElement.setText(person2.getId()+""); ageElement.setText(person2.getAge()+""); addressElement.setText(person2.getAddress()); nameElement.setText(person2.getName()); } HttpServletResponse response = ServletActionContext.getResponse(); //设置返回类型 response.setContentType("text/xml; charset=UTF-8 "); //清除浏览器缓存 response.setHeader("Cache-Control", "no-cache"); //定义输出流 PrintWriter out = response.getWriter(); //定义格式 OutputFormat format = OutputFormat.createPrettyPrint(); format.setEncoding("utf-8"); //定义XMLWriter 对象，将document 对象，输出到客户端 XMLWriter writer = new XMLWriter(out,format); writer.write(document); out.flush(); out.close(); return null; } }
JSON
1、引入struts2-json-plugin.jar、json-lib.jar包
2、配置struts.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"> <struts>
// 继承自json-default 而json-default继承自 struts-default <package name="testSSH" extends="json-default"> //异步请求不定义返回值 <action name="getXmlAction" class="com.test.action.xml.GetXmlAction"></action>
//异步请求返回值为SUCCESS，定义类型为json 即可,客户端到服务端序列化的过程交由core 处理 <action name="getJsonAction" class="com.test.action.json.GetJsonAction"> <result name="success" type="json">
//排除 属性 name MyAge【指向别名】 <param name="excludeProperties">name,MyAge</param>
// 只解析root <param name="root">person</param> </result> </action> </package> </struts>
3、定义GetJsonAction.java
package com.test.action.json; import org.apache.struts2.json.annotations.JSON; import java.util.*; import com.opensymphony.xwork2.ActionSupport; import com.test.action.json.person; public class GetJsonAction extends ActionSupport { private static final long serialVersionUID = 1L; //客户端传入的名称 private String name; private int age; private String address; private int id; private Date date; private person person = new person(); public person getPerson() { return person; } public void setPerson(person person) { this.person = person; } @JSON(format = "yyyy-MM-dd") public Date getDate() { return date; } public void setDate(Date date) { this.date = date; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } @JSON(name = "MyAddress") public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } @JSON(serialize=false) public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } //将Action 的成员变量序列化成json对象 @Override public String execute() throws Exception { person person1 = new person(); person1.setAge(11); person1.setName("james"); person1.setId(1); person1.setAddress("beijing"); person1.setDate(new Date()); person person2 = new person(); person2.setId(2); person2.setAddress("shanghai"); person2.setAge(12); person2.setName("currey"); person2.setDate(new Date()); if("james".equals(this.name)){ this.id = person1.getId(); this.age = person1.getAge(); this.address = person1.getAddress(); this.date = person1.getDate(); }else{ this.id = person2.getId(); this.age = person2.getAge(); this.address = person2.getAddress(); this.date = person2.getDate(); } return SUCCESS; } }
4、定义person属性类
package com.test.action.json; import java.util.*; public class person { private int id; private String name; private int age; private String address; private Date date; public Date getDate() { return date; } public void setDate(Date date) { this.date = date; } public int getId() { return id; } public void setId(int id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } }
5、引入jsonText.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <script type="text/javascript" src="js/jquery-1.8.2.js"></script> <script type="text/javascript" src="scripts/common.js"></script> </head> <body id="xmlbody"> <select id="name"> <option value="james" selected="selected">james</option> <option value="currey">currey</option> </select> <input type="button" value="getInfo" onclick="getJson();"/> </body> </html>
