跟我一起学extjs5(29--加入模块和菜单定义[2建立java bean])

对上一节中加入的4个模块在java中建立相应的bean文件。

以上表建立好以后，需要建立java bean文件。在建立之前需要加入几个支持类。
先在com.jfok.server.common中建立包annotation，再在下面加入二个类库，这二个是自定义的注释类。分别用来注释每一个模块的信息和模块中每一字段的信息。

package com.jfok.server.common.annotation;

import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;

/**
 * 用来注释模块
 * 
 * @author jiangfeng
 */
@Retention(RetentionPolicy.RUNTIME)
public @interface TableDefine {

	// 此表的id号,为一个4位数字
	int id();

	// 模块名称
	String title();

	// 模块简称
	String shortname() default "";

	// 模块分组名称
	String group();

	// 模块的主键是否可以是分级的，如果是可以分级的，可定义为"2,2,2",表示有三级，每级代码长为2位，
	// 比如会计科目可以这样来定义
	// 10
	// 1001
	// 100101
	// 100102
	// 100102
	// 1002
	// ......
	String codeLevel() default "";

	// 模块是否有附件
	boolean attachment() default false;

}

package com.jfok.server.common.annotation;

import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;

/**
 * 用来注释模块中的每个字段
 * 
 * @author jiangfeng
 * 
 */
@Retention(RetentionPolicy.RUNTIME)
public @interface FieldDefine {

	String title();

	int number() default 0;

	String remark() default "";

	boolean nameField() default false;

	boolean hidden() default false;

	String fieldGroup() default "默认组";

}

在com.jfok.server.hibernate中建立包system,把系统用到的bean文件都放在这个目录下。先建立一个接口文件：

package com.jfok.server.hibernate.system;

/**
 * 有此接口的类，都是系统模块的控制类
 * 
 * @author jfok
 * 
 */
public interface _IModuleControlInterface {

}

再建立_ModuleGroup.java

package com.jfok.server.hibernate.system;

import java.io.Serializable;

import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;

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

/**
 * 模块分组类，每一个模块都有一个大类分组
 * 
 * @author jfok 2012.11.7
 */
@SuppressWarnings("serial")
@Entity
@org.hibernate.annotations.Entity(dynamicUpdate = true)
@TableDefine(group = "系统模块", id = 9901, title = "模块分组")
public class _ModuleGroup implements _IModuleControlInterface, Serializable {

	public static final String TITLE = "tf_title";

	@Id
	@FieldDefine(title = "模块分组序号", number = 10)
	@Column(nullable = false, length = 10)
	private String tf_moduleGroupId;

	@FieldDefine(title = "模块分组名称", nameField = true, number = 20)
	@Column(nullable = false, length = 50)
	private String tf_title;

	@FieldDefine(title = "描述", number = 30)
	private String tf_description;

	@FieldDefine(title = "图标地址", number = 40)
	private String tf_iconURL;

	@FieldDefine(title = "备注", number = 50)
	private String tf_remark;

	public _ModuleGroup() {

	}
  // setter and getter
}

上面这个类中，就用自定义的注释类来进行了注释，一个是注释在类名上，一个是注释在各个字段上。这二个类注释的功能是以后在增加一个模块的时候，会自动把这些注释的信息自动的加到保存的模块和模块字段的表中。

再加入_Module.java

package com.jfok.server.hibernate.system;

到现在为止，我们建立好了数据表以及java bean文件，下面可以开发前后台进行协同工作的内容了。
各个文件的目录结构：
