模块“市”的设计与加入

        现在重复加入“省”模块的过程，来加入市的模块。

1、建立数据表City

CREATE TABLE [dbo].[City](
	[tf_cityId] [nvarchar](4) COLLATE Chinese_PRC_CI_AS NOT NULL,
	[tf_provinceId] [nvarchar](2) COLLATE Chinese_PRC_CI_AS NOT NULL,
	[tf_name] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NOT NULL,
	[tf_postNumber] [nvarchar](6) COLLATE Chinese_PRC_CI_AS NULL,
	[tf_telHead] [nvarchar](50) COLLATE Chinese_PRC_CI_AS NULL,
	[tf_money] [money] NOT NULL CONSTRAINT [DF_City_tf_money]  DEFAULT ((0)),
	[tf_remark] [nvarchar](max) COLLATE Chinese_PRC_CI_AS NULL,
 CONSTRAINT [PK_City] PRIMARY KEY CLUSTERED 
(
	[tf_cityId] ASC
)WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

ALTER TABLE [dbo].[City]  WITH CHECK ADD  CONSTRAINT [FK_City_Province] FOREIGN KEY([tf_provinceId])
REFERENCES [dbo].[Province] ([tf_provinceId])
ON UPDATE CASCADE

*对市名称建立唯一索引
CREATE UNIQUE NONCLUSTERED INDEX [IX_City] ON [dbo].[City] 
(
	[tf_name] ASC
)WITH (SORT_IN_TEMPDB = OFF, DROP_EXISTING = OFF, IGNORE_DUP_KEY = OFF, ONLINE = OFF) ON [PRIMARY]

2、建立hibernate Bean: City.java 

package com.jfok.server.hibernate.sales;

import java.io.Serializable;

import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;

import org.codehaus.jackson.map.annotate.JsonSerialize;

import com.jfok.server.common.annotation.FieldDefine;
import com.jfok.server.common.annotation.TableDefine;

@Entity
@SuppressWarnings("serial")
@JsonSerialize(include = JsonSerialize.Inclusion.NON_EMPTY)
@org.hibernate.annotations.Entity(dynamicUpdate = true)
@TableDefine(group = "编码设置", id = 7012, title = "市")
public class City implements Serializable {

	@Id
	@FieldDefine(title = "编码", number = 10, fieldGroup = "基本信息")
	@Column(nullable = false, length = 4)
	// 所有的数据表字段，全部用tf_开头，只是为了好分别表字段还是普通bean字段而己
	private String tf_cityId;

	// manyToOne 定义了此模块的一个父模块。不用在Province定义oneToMany了,这里的父子关系是双向的。
	@ManyToOne(cascade = CascadeType.REFRESH, fetch = FetchType.EAGER)
	@JoinColumn(name = "tf_provinceId", nullable = false)
	@FieldDefine(title = "省份", number = 20, fieldGroup = "基本信息")
	private Province tf_Province;

	@FieldDefine(title = "名称", number = 30, nameField = true, fieldGroup = "基本信息")
	@Column(nullable = false, length = 50, unique = true)
	private String tf_name;

	@FieldDefine(title = "邮政编码", number = 40, fieldGroup = "附加信息")
	@Column(length = 6)
	private String tf_postNumber;

	@FieldDefine(title = "电话区号", number = 50, fieldGroup = "附加信息")
	@Column(length = 6)
	private String tf_telHead;

	// 此字段无实际意义，只是为了某些功能的展示所用
	@FieldDefine(title = "金额属性", number = 70, fieldGroup = "附加信息")
	private Double tf_money = 0.0;

	@FieldDefine(title = "备注", number = 190, fieldGroup = "附加信息")
	private String tf_remark;

	public City() {

	}
 //setter and getter

3?在配置文件hibernate.cfg.xml中加入

		<mapping class="com.jfok.server.hibernate.sales.City" />

        至此编码阶段就完成了，下面要做的就是将模块导入系统，然后进行配置了。

4?导入模块“市”。进入“模块管理”，按导入模块按钮。

确定后，将会导入City模块，模块字段，生成缺省的grid和form。

下面看一下导入的City的字段。

现在展示一下省份这个manyToOne字段的属性。

5、给City模块加入角色操作权限；

6、将City模块加入到菜单。

上二个步骤参见前面模块“省”操作。

至此一个新的模块City加入成功。
