跟我一起學extjs5(30--加入模組和菜單定義[3後台系統資料的組織和產生])
        對於大多web程式來說，後台是完成控制和處理的，前台就是一個展示工具，這個系統也是這樣。在上一節中建立了四個模組，下面開始設計前背景互動。將系統資訊和模組、菜單資訊傳到前台，由前台來進行展示。        首先建立一個java bean類用來存放各種需要傳到前台的資料，裡麵包括：系統資訊、操作人員資訊、服務人員資訊、模組資訊、菜單。現在只加入了這幾個，以後還要加入各種 各樣的使用權限設定。在com.jfok.server.common中新增包info,在這下面加入四個class。

package com.jfok.server.common.info;import java.io.Serializable;@SuppressWarnings("serial")// 這是服務單位情況的設定，也是放在資料庫裡的，可以進行修改public class ServiceInfo implements Serializable {private String tf_serviceDepartment;// 服務單位private String tf_serviceMen;// 服務人員private String tf_serviceTelnumber;// 聯絡電話private String tf_serviceFaxnumber;// 傳真private String tf_serviceEmail;// 電子郵件private String tf_serviceHomepage;// 首頁private String tf_serviceQQ;// ＱＱ號private String tf_copyrightOwner;// 著作權單位private String tf_copyrightInfo;// 著作權資訊public ServiceInfo() {}}

package com.jfok.server.common.info;import java.io.Serializable;@SuppressWarnings("serial")// 這是系統總體情況的設定，也是放在資料庫裡的，可以進行修改public class SystemInfo implements Serializable {private String tf_systemName; // 系統名稱private String tf_systemVersion; // 版本號碼private String tf_systemAddition;// 附加設定public SystemInfo() {}}

import java.io.Serializable;import java.util.Date;@SuppressWarnings("serial")// 這是使用者單位和登入使用者的資訊public class UserInfo implements Serializable {private String tf_userdwmc;// 使用單位名稱private Date tf_userStartdate;// 開始使用時間private Integer tf_userId;// 使用者idprivate String tf_loginName;// 使用者登入名稱private String tf_userName;// 使用者姓名private String tf_departmentId = null;// 使用者部門idprivate String tf_departmentName = null;// 使用者部門名稱public UserInfo() {}}

package com.jfok.server.common.info;import java.io.Serializable;import java.util.List;import java.util.Set;import org.codehaus.jackson.map.annotate.JsonSerialize;import com.jfok.server.hibernate.system._MenuGroup;import com.jfok.server.hibernate.system._Module;/** * 用於向用戶端返回系統的模組資訊和登入人員的資訊的類 *  * @author jfok *  */@SuppressWarnings("serial")@JsonSerialize(include = JsonSerialize.Inclusion.NON_NULL)public class ApplicationInfo implements Serializable {// 這是系統總體情況的設定，也是放在資料庫裡的，可以進行修改private SystemInfo systemInfo;// 這是使用者單位和登入使用者的資訊private UserInfo userInfo;// 這是服務單位情況的設定，也是放在資料庫裡的，可以進行修改private ServiceInfo serviceInfo;// 系統中模組的字義和菜單的定義private Set<_Module> tf_Modules; // 系統模組定義資訊private List<_MenuGroup> tf_MenuGroups; // 系統功能表// 系統中各種許可權的定義// 其他一些附加資訊需要傳送到前台的private Integer tf_additionFileMaxMB; // 上傳檔案的最大大小private String tf_previewExts; // 可預覽的檔案的尾碼名 ，用逗號分開public ApplicationInfo() {}}

        以上類的getter和setter全部自己加一下。
        繼續在com.jfok.server.service中新增一個類用來產生資料的服務類 ApplicationService.java：

package com.jfok.server.service;import java.util.Date;import java.util.HashSet;import java.util.List;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Service;import org.springframework.transaction.annotation.Propagation;import org.springframework.transaction.annotation.Transactional;import com.jfok.server.DAO.SystemBaseDAO;import com.jfok.server.common.info.ApplicationInfo;import com.jfok.server.common.info.ServiceInfo;import com.jfok.server.common.info.SystemInfo;import com.jfok.server.common.info.UserInfo;import com.jfok.server.hibernate.system._MenuGroup;import com.jfok.server.hibernate.system._Module;@Servicepublic class ApplicationService {@Resourceprivate SystemBaseDAO systemBaseDAO;// 事務注釋@SuppressWarnings("unchecked")@Transactional(propagation = Propagation.REQUIRED, readOnly = true)public ApplicationInfo getApplicationInfo(HttpServletRequest request) {ApplicationInfo result = new ApplicationInfo();// 以上內容暫時為自訂的，以後會改為從資料庫和登入資訊中讀取。SystemInfo systemInfo = new SystemInfo();systemInfo.setTf_systemName("自訂的中小型管理系統");systemInfo.setTf_systemVersion("2014.09.28");result.setSystemInfo(systemInfo);UserInfo userInfo = new UserInfo();userInfo.setTf_userdwmc("無錫市宏宇電子有限公司");userInfo.setTf_userStartdate(new Date());userInfo.setTf_userName("管理員");userInfo.setTf_loginName("admin");userInfo.setTf_userId(0);userInfo.setTf_departmentId("00");userInfo.setTf_departmentName("工程部");result.setUserInfo(userInfo);ServiceInfo serviceInfo = new ServiceInfo();serviceInfo.setTf_serviceDepartment("熙旺公司");serviceInfo.setTf_serviceMen("蔣鋒");serviceInfo.setTf_serviceTelnumber("1320528xxxx");serviceInfo.setTf_serviceFaxnumber("0510-88888888");serviceInfo.setTf_serviceQQ("7858xxxx");serviceInfo.setTf_serviceEmail("jfok1972@qq.com");serviceInfo.setTf_serviceHomepage("www.www.net");serviceInfo.setTf_copyrightInfo("熙旺公司著作權");serviceInfo.setTf_copyrightOwner("熙旺軟體");result.setServiceInfo(serviceInfo);// 把所有的模組定義資訊加進去result.setTf_Modules(new HashSet<_Module>((List<_Module>) systemBaseDAO.findAll(_Module.class)));// 加入菜單分組result.setTf_MenuGroups((List<_MenuGroup>) systemBaseDAO.findAll(_MenuGroup.class));for (_MenuGroup mg : result.getTf_MenuGroups()) {// 加入這一條是為了讓菜單組下面的菜單也執行sql 語句加進來，不然的話，返回以後mvc要加入菜單，// 就會在執行sql的時候因為session已經關閉而報錯mg.getTf_menuModules().size();}return result;}}

        在上面用到了DAO類，我自己做了一個系統的基本DAO類接品和類，放在包com.jfok.server.DAO之下。

package com.jfok.server.DAO;import java.util.List;@SuppressWarnings("rawtypes")public interface ISystemBaseDAO {public void save(Object record);public void attachDirty(Object record, Object old);public void delete(Object record);public Object findById(Class<?> className, Object id);public Object findById(String beanClassName, Object id);public List findByProperty(Class<?> className, String propertyName,Object value);public Object findByPropertyFirst(Class<?> className, String propertyName,Object value);public List findByString(Class<?> className, String value);public List findByProperty(String beanClassName, String propertyName,Object value);public List findByPropertyWithOtherCondition(Class<?> className, String propertyName,Object value , String otherCondString);public List findByLikeProperty(String beanClassName, String propertyName,Object value);public List findByLikePropertyWithOtherCondition(String beanClassName, String propertyName,Object value, String otherCondString);public List findByPropertyWithOtherCondition(String beanClassName, String propertyName,Object value , String otherCondString);public List findByPropertyAllSort(String beanClassName, String sort,String dir, String propertyName, Object value, String defaultSort,String defaultDir);public List findAll(Class<?> className);public List findAll(String className);public List findAllSort(String beanClassName, String sort, String dir);List findByPropertyAllSort(Class<?> className, String sort, String dir,String propertyName, Object value, String defaultSort, String defaultDir);}

        最後加入spring MVC的控制類，在com.jfok.server.controller中新增一個類ApplicationController.java:

package com.jfok.server.controller;import javax.annotation.Resource;import javax.servlet.http.HttpServletRequest;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.ResponseBody;import com.jfok.server.common.info.ApplicationInfo;import com.jfok.server.service.ApplicationService;@Controllerpublic class ApplicationController {// spring注釋，自動注入ApplicationService 的執行個體@Resourceprivate ApplicationService applicationService;@RequestMapping("/applicationinfo.do")public synchronized @ResponseBodyApplicationInfo getApplicationInfo(HttpServletRequest request) {return applicationService.getApplicationInfo(request);}}
