tapestry5.0之Grid

1.tml文件

<t:layout  xmlns:t="http://tapestry.apache.org/schema/tapestry_5_0_0.xsd">   
    <t:beaneditform t:id="user" submitlabel="Create User" object="user"/>
    
    <h1>List Users</h1>
        <t:grid source="users" row="user" rowsPerPage="5" pagerPosition="bottom" empty="nodata"
         t:rowClass="literal:evenodd" add="operation">
            <t:parameter name="userNameCell">
                <t:pagelink page="user/edit" context="user.id">${user.userName}</t:pagelink>
            </t:parameter>
			<t:parameter name="operationCell">
                <t:actionlink t:id="delete" context="user.id">Delete</t:actionlink>
            </t:parameter>
        </t:grid>
</t:layout>   

2.java文件

package com.logcd.tapestry5.myapp.pages.user;

import java.util.List;

import org.apache.tapestry5.annotations.IncludeStylesheet;
import org.apache.tapestry5.ioc.annotations.Inject;

import com.logcd.myapp.dao.UserDao;
import com.logcd.myapp.models.User;

@SuppressWarnings("unchecked")
@IncludeStylesheet("classpath:com/logcd/tapestry5/myapp/pages/user/CreateUser.css")
public class CreateUser {

    private User user;
	
	@Inject
    private UserDao userDao;

	public CreateUser(){}
	
	public void setUser(User user) {
		this.user = user;
	}

	public User getUser() {
		return user;
	}

	Object onSuccess() {
		user.setPhones(null);
		userDao.save(user);
        return CreateUser.class;
    }
	
    void onActionFromDelete(long userId){
    	userDao.delete(userDao.findById(userId));
	}  
   
	public List<User> getUsers() { return userDao.findAll(); }
}

3.properties文件

#定义表头文本
operation-label=操作
userName-label=用户名称
emailAddress-label=电子邮箱
birthday-label=出生日期
role-label=角色

也可以在java文件中定义表头

	@Inject  
	private BeanModelSource beanModelSource;   
	
	@Inject  
	private ComponentResources componentSources; 
	 
	@Inject   
	private Messages _messages; 

	private BeanModel userBeanModel;
	public BeanModel getUserBeanModel(){
		return buildUserBeanModel(beanModelSource,componentSources);
	}

	public BeanModel buildUserBeanModel(BeanModelSource beanModelSource, ComponentResources componentSources){
		if(userBeanModel == null){
			userBeanModel = beanModelSource.createEditModel(User.class,_messages); 
			userBeanModel.get("userName").label("用户名");
			userBeanModel.get("emailAddress").label("电子邮箱");
			userBeanModel.get("birthday").label("出生日期");
			userBeanModel.get("role").label("角色");
			userBeanModel.add("operation",new LogcdPropertyConduit()).label("操作");
		}
		return userBeanModel;
	}

同时给grid标签加上model="userBeanModel"就可以了。

public class LogcdPropertyConduit implements PropertyConduit{

	public Object get(Object arg0) {
		return "";
	}

	@SuppressWarnings("unchecked")
	public Class getPropertyType() {
		return String.class;
	}

	public void set(Object arg0, Object arg1) {
		
	}

	public <T extends Annotation> T getAnnotation(Class<T> arg0) {
		return null;
	}

}
