}
}
4.类型转换配置文件UserAction-conversion.properties
user=com.WildCat.converter.UserConverter
5.类型转换器
package com.WildCat.converter;
import java.util.Map;
import java.util.StringTokenizer;
import com.WildCat.bean.User;
import ognl.DefaultTypeConverter;
public class UserConverter extends DefaultTypeConverter {
@Override
public Object convertValue(Map context, Object value, Class toType) {
if (User.class==toType)//从页面向后台转换
{
String[] str=(String[])value;
String firstValue=str[0];
StringTokenizer st=new StringTokenizer(firstValue,":");
String username=st.nextToken();
String password=st.nextToken();
User user=new User();
user.setUsername(username);
user.setPassword(password);
return user;
}
else if (String.class==toType)//从后台对象向前台转换
{
User user=(User)value;
String username=user.getUsername();
String password=user.getPassword();
String userInfo="UserName: "+username+" PassWord: "+password;
return userInfo;
}
return null;
}
}6.Action
package Struts2.WildCat.com;
import com.WildCat.bean.User;
import com.opensymphony.xwork2.ActionSupport;
public class UserAction extends ActionSupport {
private User user;
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
@Override
public String execute() throws Exception {
System.out.println("UserName: "+user.getUsername());
System.out.println("PassWord: "+user.getPassword());
return SUCCESS;
}
}
