Tapestry 5.3.8 + Spring 4.0.5 小例子（二）

上篇 把项目（Crud）整体搭建完成，本章继续写项目的实现。

1、创建数据库表People：

create table PEOPLE
(
  ID       NUMBER primary key,
  NAME     NVARCHAR2(10),
  AGE      NUMBER,
  BIRTHDAY DATE,
  GENDER   NVARCHAR2(10),
  HOBBY    NVARCHAR2(30)
)

2、创建实体类：

/**
 * @package ：example.crud.entity<br>
 * @author ：wanglongjie<br>
 * @createDate ：2015年8月17日上午9:26:32<br>
 */
package example.crud.entity;

import java.util.Date;

import org.apache.tapestry5.beaneditor.NonVisual;

/**
 * @package ：example.crud.entity<br>
 * @file ：People.java<br>
 * @describe ：用户 实体类<br>
 * @author ：wanglongjie<br>
 * @createDate ：2015年8月17日上午9:26:32<br>
 * @updater ：<br>
 * @updateDate ：<br>
 * @updateContent ：<br>
 */
public class People {
	/**
	 * 
	 */
	public People() {
		// TODO Auto-generated constructor stub
		birthday = new Date();
	}

	/**
	 * ID 好
	 */
	@NonVisual
	private int id;
	/**
	 * 姓名
	 */
	private String name;
	/**
	 * 年龄
	 */
	private int age;
	/**
	 * 生日
	 */
	private Date birthday;
	/**
	 * 性别
	 */
	private Gender gender;
	/**
	 * 兴趣爱好
	 */
	private String hobby;

	public int getId() {
		return id;
	}

	public void setId(int id) {
		this.id = id;
	}
        
        // 其他属性的set，get方法
        // ......

	@Override
	public String toString() {
		return "People [id=" + id + ", name=" + name + ", age=" + age
				+ ", birthday=" + birthday + ", gender=" + gender + ", hobby="
				+ hobby + "]";
	}

}

创建 枚举类型代表性别：

package example.crud.entity;

public enum Gender {
	男, 女;
}

创建 查询帮助实体：

/**
 * @package ：example.register.entity<br>
 * @author ：wanglongjie<br>
 * @createDate ：2015年8月18日下午1:43:01<br>
 */
package example.crud.entity;

/**
 * @package ：example.register.entity<br>
 * @file ：QueryPeople.java<br>
 * @describe ：查询实体<br>
 * @author ：wanglongjie<br>
 * @createDate ：2015年8月18日下午1:43:01<br>
 * @updater ：<br>
 * @updateDate ：<br>
 * @updateContent ：<br>
 */
public class QueryPeople {
	private String flag;
	private Gender gender;
	private int minAge = 0;
	private int maxAge = 100;
	private String name;
	private String hobby;
	private String minBirthday;
	private String maxBirthday;

	public QueryPeople() {
		// TODO Auto-generated constructor stub
		minAge = 0;
		maxAge = 100;
		flag = "";
	}

	public Gender getGender() {
		return gender;
	}

	public void setGender(Gender gender) {
		this.gender = gender;
	}

	// 其他属性的set，get方法
        // ......

	@Override
	public String toString() {
		return "QueryPeople [flag=" + flag + ", gender=" + gender + ", minAge="
				+ minAge + ", maxAge=" + maxAge + ", name=" + name + ", hobby="
				+ hobby + ", minBirthday=" + minBirthday + ", maxBirthday="
				+ maxBirthday + "]";
	}

}

3、创建接口，及完成接口实现类：

/**
 * @package ：example.crud.dao<br>
 * @author ：wanglongjie<br>
 * @createDate ：2015年8月17日上午9:26:19<br>
 */
package example.crud.dao;

import java.util.List;
import java.util.Map;

import example.crud.entity.People;

/**
 * @package ：example.crud.dao<br>
 * @file ：PeopleDao.java<br>
 * @describe ：用户Dao接口<br>
 * @author ：wanglongjie<br>
 * @createDate ：2015年8月17日上午9:26:19<br>
 * @updater ：<br>
 * @updateDate ：<br>
 * @updateContent ：<br>
 */
public interface PeopleDao {
	/**
	 * 
	 * @method ：save<br>
	 * @describe ：保存用户<br>
	 * @author ：wanglongjie<br>
	 * @createDate ：2015年8月17日上午9:30:14 <br>
	 * @param people
	 * @return boolean
	 */
	boolean save(People people);

	/**
	 * 
	 * @method ：delete<br>
	 * @describe ：删除用户<br>
	 * @author ：wanglongjie<br>
	 * @createDate ：2015年8月17日上午9:30:23 <br>
	 * @param people
	 * @return boolean
	 */
	boolean delete(People people);

	/**
	 * 
	 * @method ：delete<br>
	 * @describe ：根据ID删除用户<br>
	 * @author ：wanglongjie<br>
	 * @createDate ：2015年8月17日上午9:30:33 <br>
	 * @param id
	 * @return boolean
	 */
	boolean delete(long id);

	/**
	 * 
	 * @method ：update<br>
	 * @describe ：更新用户<br>
	 * @author ：wanglongjie<br>
	 * @createDate ：2015年8月17日上午9:30:47 <br>
	 * @param people
	 * @return boolean
	 */
	boolean update(People people);

	/**
	 * 
	 * @method ：findById<br>
	 * @describe ：根据ID查找用户<br>
	 * @author ：wanglongjie<br>
	 * @createDate ：2015年8月17日上午9:30:57 <br>
	 * @param id

	 */
	People findById(long id);

	/**
	 * 
	 * @method ：findAll<br>
	 * @describe ：查找所有用户<br>
	 * @author ：wanglongjie<br>
	 * @createDate ：2015年8月17日上午9:31:24 <br>
	 * @return List<People>
	 */
	List<People> findAll();

	/**
	 * 
	 * @method ：findByCondition<br>
	 * @describe ：根据条件查找用户<br>
	 * @author ：wanglongjie<br>
	 * @createDate ：2015年8月17日上午9:31:40 <br>
	 * @param condition
	 * @return List<People>
	 */
	List<People> findByCondition(Map<String, Object> condition);

	/**
	 * 
	 * @method ：findAllNames<br>

4、将接口配置到Spring的Ioc容器，上篇的spring-service.xml已配置，也可采用Tapestry5专门配置服务的办法。

5、创建页面类，及页面模板：

至此，页面类与页面模板已创建完毕。代码中看到的两个页面类都继承了Base.java，是因为两个页面类都需要的东西，提取出来，生成一个基础类，该类必须放在pages包下的base包里面。

/**
 * @package ：example.crud.pages.base<br>
 * @author ：wanglongjie<br>
 * @createDate ：2015年8月18日下午4:44:46<br>
 */
package example.crud.pages.base;

import org.apache.tapestry5.SelectModel;
import org.apache.tapestry5.annotations.Import;
import org.apache.tapestry5.ioc.Messages;
import org.apache.tapestry5.ioc.annotations.Inject;
import org.apache.tapestry5.util.EnumSelectModel;

import example.crud.entity.Gender;

/**

 * @createDate ：2015年8月18日下午4:44:46<br>
 * @updater ：<br>
 * @updateDate ：<br>
 * @updateContent ：<br>
 */
@Import(library = "context:js/My97DatePicker/WdatePicker.js")
public class Base {
	@Inject
	private Messages messages;

	public SelectModel getGenders() {
		return new EnumSelectModel(Gender.class, messages);
	}

	public Gender getMale() {
		return Gender.男;
	}

	public Gender getFemale() {
		return Gender.女;
	}
}

整个代码已贴完了！部署到Tomcat下，浏览器打开“http://localhost:8888/Crud/Start”，即可看到页面
