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.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; /** * 系统中每个模块的字义 * * @author jfok 2012.11.7 * */ @JsonSerialize(include = JsonSerialize.Inclusion.NON_EMPTY) @SuppressWarnings("serial") @Entity @org.hibernate.annotations.Entity(dynamicUpdate = true) @TableDefine(group = "系统模块", id = 9902, title = "系统模块") public class _Module implements _IModuleControlInterface, Serializable { public static final String MODULEID = "tf_moduleId"; public static final String MODULENAME = "tf_moduleName"; @Id @FieldDefine(title = "模块ID号", number = 10) @Column(nullable = false, length = 10) private String tf_moduleId; // 模块ID,模块序号 @ManyToOne(cascade = CascadeType.REFRESH, fetch = FetchType.EAGER) @JoinColumn(name = "tf_moduleGroupId") @FieldDefine(title = "模块分组", number = 20) private _ModuleGroup tf_ModuleGroup; @FieldDefine(title = "模块标识", number = 30) @Column(nullable = false, length = 50, updatable = false) private String tf_moduleName; // 模块英文名称 @FieldDefine(title = "模块名称", nameField = true, number = 40) @Column(nullable = false, length = 50) private String tf_title;

@FieldDefine(title = "文件字段", number = 96) @Column(length = 50) private String tf_fileField; @FieldDefine(title = "主页上顺序", number = 99) @Column(length = 50) private String tf_homePageTag; @FieldDefine(title = "模块描述", number = 100) @Column(length = 50) private String tf_description; @FieldDefine(title = "请求地址", number = 110) @Column(nullable = false, length = 50) private String tf_requestMapping;// 系统中后台服务的调用接入点 user.do,employee.do 等 @FieldDefine(title = "图标地址", number = 120) @Column(length = 50) private String tf_iconURL; @FieldDefine(title = "默认排序字段", number = 130) private String tf_defaultOrderField; @FieldDefine(title = "行操作", remark = "新增及修改操作都行内完成", number = 140) @Column(nullable = false) private Boolean tf_isInlineOper; // 如部门编码为 2,2,2,2,2 @FieldDefine(title = "编码级次", remark = "如果设置了编码级次,则主键的长度必须是此级次中的,并且必须有父级编码存在", number = 150) @Column(length = 50) String tf_codeLevel; @FieldDefine(title = "联动模块", remark = "在本模块的数据增删改后,打开的联动模块都要刷新数据。", number = 155) @Column(length = 200) private String tf_linkedModule; @FieldDefine(title = "可用", number = 160) @Column(nullable = false) private Boolean tf_isEnable = false; @FieldDefine(title = "可浏览", number = 170) @Column(nullable = false) private Boolean tf_hasBrowse = false;

@FieldDefine(title = "备注", number = 800) private String tf_remark; public _Module() { } // setter and getter }

        _MenuGroup.java
package com.jfok.server.hibernate.system; import java.io.Serializable; import java.util.List; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.Id; import javax.persistence.Transient; import com.jfok.server.common.annotation.FieldDefine; import com.jfok.server.common.annotation.TableDefine; /** * 菜单分组 * * @author jfok * */ @SuppressWarnings("serial") @Entity @org.hibernate.annotations.Entity(dynamicUpdate = true) @TableDefine(group = "系统模块", id = 9920, title = "菜单分组") public class _MenuGroup implements _IModuleControlInterface, Serializable { @Id @FieldDefine(title = "顺序号", remark = "菜单分组按顺序号显示在菜单条上", number = 10) @Column(length = 10, nullable = false) private String tf_menuGroupId; @FieldDefine(title = "分组名称", nameField = true, number = 20) @Column(length = 50, nullable = false) private String tf_title; @FieldDefine(title = "展开", remark = "在树状菜单下默认是否展开", number = 30) private Boolean tf_expand; @FieldDefine(title = "图标glyph", number = 40) private Boolean tf_glyph; @FieldDefine(title = "图标文件名", remark = "图标放置于/images/module/目录下", number = 50) @Column(length = 50) private String tf_iconURL; @FieldDefine(title = "分组描述", number = 60) @Column(length = 50) private String tf_description; @FieldDefine(title = "备注", number = 70) private String tf_remark; @Transient private List<_MenuModule> tf_menuModules; public _MenuGroup() { } //setter and getter }

        _MenuModule.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.GeneratedValue; import javax.persistence.Id; import javax.persistence.JoinColumn; import javax.persistence.ManyToOne; import org.codehaus.jackson.annotate.JsonIgnore; import org.hibernate.annotations.GenericGenerator; import com.jfok.server.common.annotation.FieldDefine; import com.jfok.server.common.annotation.TableDefine; /** * 系统可使用的菜单项 * * @author jfok * */ @SuppressWarnings("serial") @Entity @org.hibernate.annotations.Entity(dynamicUpdate = true) @TableDefine(group = "系统模块", id = 9921, title = "系统菜单") public class _MenuModule implements _IModuleControlInterface, Serializable { @Id @FieldDefine(title = "ID号", hidden = true, number = 10) @GeneratedValue(generator = "increment") @GenericGenerator(name = "increment", strategy = "increment") private Integer tf_menuModuleId; @FieldDefine(title = "顺序号", remark = "按顺序号显示在菜单中", number = 20) @Column(nullable = false) private Integer tf_orderId; @JsonIgnore @ManyToOne(cascade = CascadeType.REFRESH, fetch = FetchType.EAGER) @JoinColumn(name = "tf_menuGroupId", nullable = false) @FieldDefine(title = "菜单分组", nameField = true, number = 30) private _MenuGroup tf_MenuGroup; @JsonIgnore @ManyToOne(cascade = CascadeType.REFRESH, fetch = FetchType.EAGER) @JoinColumn(name = "tf_moduleId", nullable = false) @FieldDefine(title = "系统模块", number = 40) private _Module tf_Module; @FieldDefine(title = "父菜单标题", number = 50) @Column(length = 20) private String tf_parentMenu; @FieldDefine(title = "分隔下一条", number = 60) private Boolean tf_addSeparator; @FieldDefine(title = "菜单标题", number = 70) @Column(length = 50) private String tf_title; @FieldDefine(title = "父模块约束设置", number = 80) private String tf_parentFilter; // 这个字段用于传送json到前台,放在json中 @Column(insertable = false, updatable = false) private String tf_ModuleId; public _MenuModule() { } // setter and getter }

        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"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property> <property name="hibernate.connection.url">jdbc:sqlserver://10.211.55.5:1433;databaseName=extjs5</property> <property name="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</property> <property name="hibernate.connection.username">sa</property> <property name="hibernate.connection.password"></property> <property name="hibernate.connection.autocommit">false</property> <property name="format_sql">true</property> <property name="show_sql">true</property> <!-- 系统模块 --> <mapping class="com.jfok.server.hibernate.system._ModuleGroup" /> <mapping class="com.jfok.server.hibernate.system._Module" /> <mapping class="com.jfok.server.hibernate.system._MenuGroup" /> <mapping class="com.jfok.server.hibernate.system._MenuModule" /> </session-factory> </hibernate-configuration>

        
        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:
