2.java文件

Java 代码

}

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;

}
void onActionFromDelete(long userId){
    userDao.delete(userDao.findById(userId));
}  
public List<User> getUsers() { return userDao.findAll(); }

}

3.properties文件

Java 代码

#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

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

Java 代码

@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;

}

@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。

Java 代码

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 getAnnotation(Class arg0) {
return null ;
}

}

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;
}
