跟我一起學extjs5(29--加入模塊和菜單定義[2建立java bean])
對上一節中加入的4個模塊在java中建立相應的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幾個支持類。
先在com.jfok.server.common中建立包annotation，再在下面加入二個類庫，這二個是自定義的注釋類。分別用來注釋每一個模塊的信息和模塊中每一字段的信息。
package com.jfok.server.common.annotation;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
/**
* 用來注釋模塊
*
* @author jiangfeng
*/
@Retention(RetentionPolicy.RUNTIME)
public @interface TableDefine {
// 此表的id號,為一個4位數字
int id();
// 模塊名稱
String title();
// 模塊簡稱
String shortname() default "";
// 模塊分組名稱
String group();
// 模塊的主鍵是否可以是分級的，如果是可以分級的，可定義為"2,2,2",表示有三級，每級代碼長為2位，
// 比如會計科目可以這樣來定義
// 10
// 1001
// 100101
// 100102
// 100102
// 1002
// ......
String codeLevel() default "";
// 模塊是否有附件
boolean attachment() default false;
}
package com.jfok.server.common.annotation;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
/**
* 用來注釋模塊中的每個字段
*
* @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 "默認組";
}
在com.jfok.server.hibernate中建立包system,把系統用到的bean文件都放在這個目錄下。先建立一個接口文件：
package com.jfok.server.hibernate.system;
/**
* 有此接口的類，都是系統模塊的控制類
*
* @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;
/**
* 模塊分組類，每一個模塊都有一個大類分組
*
* @author jfok 2012.11.7
*/
@SuppressWarnings("serial")
@Entity
@org.hibernate.annotations.Entity(dynamicUpdate = true)
@TableDefine(group = "系統模塊", id = 9901, title = "模塊分組")
public class _ModuleGroup implements _IModuleControlInterface, Serializable {
public static final String TITLE = "tf_title";
@Id
@FieldDefine(title = "模塊分組序號", number = 10)
@Column(nullable = false, length = 10)
private String tf_moduleGroupId;
@FieldDefine(title = "模塊分組名稱", 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 = "圖標地址", number = 40)
private String tf_iconURL;
@FieldDefine(title = "備注", number = 50)
private String tf_remark;
public _ModuleGroup() {
}
// setter and getter
}
上面這個類中，就用自定義的注釋類來進行了注釋，一個是注釋在類名上，一個是注釋在各個字段上。這二個類注釋的功能是以后在增加一個模塊的時候，會自動把這些注釋的信息自動的加到保存的模塊和模塊字段的表中。
再加入_Module.java
package com.jfok.server.hibernate.system;
import java.io.Serializable;
import javax.persistence.CascadeType;
import javax.persistence.Column;

import 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個class加入到配置文件中。
