ongl(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>

<package name="default" extends="struts-default">
<action name="showOriginalAndJavaBeanAction" class="cn.jbit.action.ShowOriginalAndJavaBeanAction">
<result>result.jsp</result>
</action>
</package>
</struts>

result.jsp

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

在搜索栏输入http://localhost:8080/Struts2_OGNL/showOriginalAndJavaBeanAction即可访问。
