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;
import java.io.Serializable;
import javax.persistence.CascadeType;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.FetchType;

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;
/**

*
*/

再修改 hibernate.cfg.xml,把上面4个class加入到配置文件中。
<?xml version="1.0" encoding="UTF-8"?>

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：
