Service Introduction(Each service runs independently with high availability and low coupling
1: Springcloud service ————————————————————————————-
1. Eureka registry: two Eureka services are provided, and so on. Multiple services can be made, with mutual registration, high availability and cluster deployment
2. Zipkin tracking service: distributed tracking log, based on memory storage record
3. Zuul gateway routing service: distributing requests, unified management and filtering, combined with ribbon load balancingfeignService callHystrix circuit breaker
4. Springboot admin monitoring center service: unified interface management, check the running status of each service and the health check of the actor

2: Workflow services ——————————————————————————————–
1.Model managementWeb online process designer, import and export XML, copy process, deployment process, select the handler

2.Process management: import and export process resource file, view flow chart, reflect process model according to process instance, and activate pending
3.Process in operation: view process information, current task node, current flow chart, void pause process, assign to do person, jump freely
4.The process of history: view process information, process time, process status and task initiator information
5.To do tasks: check my personal tasks and the tasks under this role, handle, reject, void and assign an agent
6.Completed tasks: view the task and process information, flow chart and process status (void and reject normally completed)

Note:When the current task is completed, the next task to be done will receive a new task message reminder by instant messaging, which will be regarded as the cancellation and completion of the task,
The task initiator will receive a message from the station
Flowable: a mainstream workflow engine

3: System services —————————————————————————————————–
1. authority management: click the secondary menu to enter the third level menu to display roles (basic permissions) and button permissions
Roles (basic permissions): divided into role groups and roles, independently assign menu permissions and add, delete, modify and query permissions. (A user can have multiple roles
Button permissions: assign button permissions to roles.
2Button Management: user defined button management, maintenance button Shiro permission identification, etc
3Menu management: N-level custom menu, select menu icon, display and hide menu status (recursive processing)
4. data dictionary: n level, support multi-level classification. Internal number, sorting, etc
5Log management: record user login and exit and some important operation records
6Online management: websocket technology, real-time detection of online user list, statistics of the number of online users, can force users to offline, the same user can only log in at one client
7System users: add, delete, modify and query the basic users, export them to excel and delete them in batch
8. in station mail: receiving and sending mailbox, timely receiving reminder made by websocket technology communication technology, and voice prompt letter can be configured
9. system settings: modify the name of the system, the number of displayed items per page, mail service configuration, and station message configuration
10Performance monitoring: drudi monitors the performance of various services, SQL monitoring, SQL firewall, URL monitoring, spring monitoring, session monitoring, etc
4: System tools Service ——————————————————————————————————————-
1. code generation: generate complete module code and keep the generation record template, which can be reused (powerful development tool)
Forward generation: generate complete module, HTML page, processing class, mapper layer, service layer, myabaits’ XML table building SQL script, etc
Reverse generation: arbitrarily connect other databases (mysql, Oracle, sqlserver) and generate modules of the cost system according to the table
2Template Management: Code online editor, manage template, save editing records, one click restore, code generator is more powerful
5: Im instant messaging service —————————————————————————————————————–
1.Friend management: search, add, delete, pull black friends, view friend information
2.Friend group: Custom friend group
3.My group: create groups, search for applications to join other people’s groups, kick out group members, and manage group chat records
Communication module single chat group chat picture send file offline message keep chat record
6: Database management service ————————————————————————————————
1. database backup: can back up single table (SQL server does not support), whole database, support local and remote backup (java interface programming technology, socket programming technology)
2. backup timer: Quartz powerful task scheduling, multi thread backup database, task start and close asynchronous operation
3. database restore: historical backup records, restore database or single table (SQL server does not support), statistics of backup time and file size
4SQL editor: powerful SQL editor, supporting editing statements, complex query statements, generating dynamic reports, and exporting to excel
7: OA office services —————————————————————————————————–
1. leave application: add a leave form and follow the workflow leave model process
8: Table synchronization service ——————————————————————————————————
According to the business requirements, it is necessary to synchronize the table data between microservices, so this intermediate service is used for processing
Menu permissions: different menu permissions are assigned to each role, and the menus seen by each role are different
Button permissions: independently assign different roles and different function permissions, add, delete, modify and query permissions assigned to different menus, and Customize button management
Support multi-user and sub authority management background,Permissions are specific to different menus and buttonsA user can have multiple roles
Technical points——————————————————————————————————————
1. Import and export excel file (applied to system users)
2 generate word file (applied to doc document generated by code generator)
3. IO stream download file (the application is generated in the code generator and compressed into a zip file to download)
4 code zip compression package(the application is generated in the code generator and compressed into a zip file)
