tapestry5.0之Grid
1.tml文件<t:layoutxmlns: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
@Injectprivate BeanModelSource beanModelSource; @Injectprivate 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;}}
