Learn extjs5 with me (30 -- add module and menu Definition [3 Organization and generation of background system data])
For most web programs, the background is controlled and processed, and the foreground is a display tool, as is the system. Four modules are created in the previous section. The interaction between the front and back ends is designed below. Transmit System Information, modules, and menus to the foreground for display. Create a java bean class to store various data that needs to be uploaded to the foreground, including system information, operator information, service personnel information, module information, and menus. Currently, only these permissions are added, and various permission settings will be added later. Add the info package to com. jfok. server. common and add four classes to it.

Package com.jfok.server.common.info; import java. io. serializable; @ SuppressWarnings ("serial") // This is the setting of the service unit, which is also stored in the database. You can modify public class ServiceInfo implements Serializable {private String tf_serviceDepartment; // private String tf_serviceMen; // private String tf_serviceTelnumber; // contact number private String tf_serviceFaxnumber; // Fax private String tf_serviceEmail; // email private String tf_serviceHomepage; // homepage private String tf_serviceQQ; // QQ No. private String tf_copyrightOwner; // All Rights Reserved units private String tf_copyrightInfo; // copyright information public ServiceInfo (){}}

Package com.jfok.server.common.info; import java. io. serializable; @ SuppressWarnings ("serial") // This is the overall situation of the system and is stored in the database. You can modify public class SystemInfo implements Serializable {private String tf_systemName; // system name private String tf_systemVersion; // version private String tf_systemAddition; // additional settings public SystemInfo (){}}

Import java. io. serializable; import java. util. date; @ SuppressWarnings ("serial") // public class UserInfo implements Serializable {private String tf_userdwmc; // use the unit name private Date tf_userStartdate; // start time private Integer tf_userId; // user idprivate String tf_loginName; // User Logon Name private String tf_userName; // user name private String tf_departmentId = null; // user department idprivate String tf_departmentName = null; // user department name 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;/*** class used to return system Module information and login personnel information to the client ** @ author jfok **/@ SuppressWarnings ("serial ") @ JsonSerialize (include = JsonSerialize. permission Sion. NON_NULL) public class ApplicationInfo implements Serializable {// set the overall situation of the system, which is also stored in the database. You can modify private SystemInfo systemInfo; // This is the private UserInfo userInfo of the user unit and the logged-on user; // This is the setting of the service unit and is also stored in the database.

Use commas to separate public ApplicationInfo (){}}

Add the getter and setter of the above classes.
Add a new class in com. jfok. server. service to generate the data service class 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.

Otherwise, mvc will add the menu after returning the result, // an error mg is reported when the session is closed during SQL Execution. getTf_menuModules (). size () ;}return result ;}}

I used the DAO class above. I made a system's basic DAO class and class, and put it under the package com. jfok. server. DAO.

Add the control class of spring MVC, and add ApplicationController. java in com. jfok. server. controller:

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 annotation, automatically injecting the ApplicationService instance @ Resourceprivate ApplicationService applicationService; @ RequestMapping ("/applicationinfo. do ") public synchronized @ ResponseBodyApplicationInfo getApplicationInfo (HttpServletRequest request) {return applicationService. getApplicationInfo (request );}}

The following figure shows how to add these files:
