原始类型和包装类型

//首先创建两个实体类 user 和 address user中包含address

package cn.jbit.bean;public class User { //用户类    private String name; //姓名    private int age;     //年龄    private Address address;//住址    public Address getAddress() {        return address;    }    public void setAddress(Address address) {        this.address = address;    }    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;    }}
package cn.jbit.bean;public class Address { // 家庭地址    private String country; // 国家    private String city; // 城市    private String street; // 街道    public String getCountry() {        return country;    }    public void setCountry(String country) {        this.country = country;    }    public String getCity() {        return city;    }    public void setCity(String city) {        this.city = city;    }    public String getStreet() {        return street;    }    public void setStreet(String street) {        this.street = street;    }}

　　2.创建出一个action先创建出两个成员变量 然后在核心方法中实例化成员变量。

package cn.jbit.action;import com.opensymphony.xwork2.ActionSupport;import cn.jbit.bean.*;public class ShowOriginalAndJavaBeanAction extends ActionSupport {    private User user;    private String message;    public String execute(){        setUser(new User());        getUser().setName("jbit");        getUser().setAge(23);        Address address=new Address();        address.setCountry("中国");        address.setCity("北京");        address.setStreet("长安街");        getUser().setAddress(address);        setMessage("展示原始类型和JavaBean");        return SUCCESS;    }    public User getUser() {        return user;    }    public void setUser(User user) {        this.user = user;    }    public String getMessage() {        return message;    }    public void setMessage(String message) {        this.message = message;    }}

　　核心配置：struts.xml

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN""http://struts.apache.org/dtds/struts-2.0.dtd"><struts><!-- <constant name="struts.custom.i18n.resources" value="http://www.mamicode.com/message"/>	--><package name="default" extends="struts-default">	<action name="showOriginalAndJavaBeanAction" class="cn.jbit.action.ShowOriginalAndJavaBeanAction"><result>result.jsp</result></action></package></struts>

　　index.jsp

<body>       信息：<s:property value="http://www.mamicode.com/message" default="展示数据" /><br/>       姓名：<s:property value="http://www.mamicode.com/user.name" /><br/>       年龄：<s:property value="http://www.mamicode.com/user.age"  /><br/>      国家：<s:property value="http://www.mamicode.com/user.address.country" />  </body>

　　在搜索栏输入localhost:8080/Struts2_OGNL/showOriginalAndJavaBeanAction访问
