ongl(示例3-6 多值类型的数据处理)
使用ognl 实现多值处理，处理的值比较多，如数组，集合等类型的数据
//实体类省略
//创建action，其中包括两个成员变量 分别是两个double,string类型的数组
package cn.jbit.action;import com.opensymphony.xwork2.ActionSupport;public class ArraysDataTransferAction extends ActionSupport { private String[] hobbies; private Double[] numbers=new Double[3]; public String execute(){ System.out.println("hobbies的长度是"+hobbies.length); for(int i=0;i<hobbies.length;i++){ System.out.println("hobbies数组中第"+i+"个元素是："+hobbies[i]); } System.out.println("numbers的长度是"+numbers.length); for(int i=0;i<numbers.length;i++){ System.out.println("numbers数组中第"+i+"个元素是："+numbers[i]); } return SUCCESS; } public String[] getHobbies() { return hobbies; } public void setHobbies(String[] hobbies) { this.hobbies = hobbies; } public Double[] getNumbers() { return numbers; } public void setNumbers(Double[] numbers) { this.numbers = numbers; }}
//再次创建另外一个action,ListDataTransferAction
package cn.jbit.action;import com.opensymphony.xwork2.ActionSupport;import cn.jbit.bean.*;import java.util.*;public class ListDataTransferAction extends ActionSupport { private List<String> hobbies; private List<Double> numbers; private List<User> users; public String execute(){ System.out.println("hobbies的长度是"+hobbies.size()); for(int i=0;i<hobbies.size();i++){ System.out.println("hobbies数组中第"+i+"个元素是："+hobbies.get(i)); } System.out.println("numbers的长度是"+numbers.size()); for(int i=0;i<numbers.size();i++){ System.out.println("numbers数组中第"+i+"个元素是："+numbers.get(i)); } System.out.println("users的长度是"+users.size()); for(int i=0;i<users.size();i++){ System.out.println("users数组中第"+i+"个元素是："+users.get(i).getName()); } return SUCCESS; } public List<String> getHobbies() { return hobbies; } public void setHobbies(List<String> hobbies) { this.hobbies = hobbies; } public List<Double> getNumbers() { return numbers; } public void setNumbers(List<Double> numbers) { this.numbers = numbers; } public List<User> getUsers() { return users; } public void setUsers(List<User> users) { this.users = users; }}
package cn.jbit.action;import com.opensymphony.xwork2.ActionSupport;import cn.jbit.bean.*;import java.util.*;public class ListDataTransferAction extends ActionSupport { private List<String> hobbies; private List<Double> numbers; private List<User> users; public String execute(){ System.out.println("hobbies的长度是"+hobbies.size()); for(int i=0;i<hobbies.size();i++){ System.out.println("hobbies数组中第"+i+"个元素是："+hobbies.get(i)); } System.out.println("numbers的长度是"+numbers.size()); for(int i=0;i<numbers.size();i++){ System.out.println("numbers数组中第"+i+"个元素是："+numbers.get(i)); } System.out.println("users的长度是"+users.size()); for(int i=0;i<users.size();i++){ System.out.println("users数组中第"+i+"个元素是："+users.get(i).getName()); } return SUCCESS; } public List<String> getHobbies() { return hobbies; } public void setHobbies(List<String> hobbies) { this.hobbies = hobbies; } public List<Double> getNumbers() { return numbers; } public void setNumbers(List<Double> numbers) { this.numbers = numbers; } public List<User> getUsers() { return users; } public void setUsers(List<User> users) { this.users = users; }}

首先需要做的是接受数据，创建出表单数据；
array_input.jsp和list_input.jsp

之后分别访问http://localhost:8080/Struts2_OGNL/ArraysDataTransfer和http://localhost:8080/Struts2_OGNL/listDataTransfer
