two。 Process management: import and export process resource files, view flow chart, reflect process model according to process instance, activate and suspend

3. Running process: view process information, current task node, current flowchart, invalidate pause process, assign undertaker

4. Historical process: view process information, process time, process status, view task initiator information

5. To-do tasks: check my personal tasks and tasks under this role, handle, reject, invalidate, and assign an agent

6. Completed tasks: check the tasks you have handled, as well as process information, flow chart, process status (invalid and rejected)

Note: when the current task is completed, the person waiting for the next task will receive an instant message reminder of the new task when the task is invalidated or completed.

The task initiator will be notified by the message from the station.

Three: system services--

Rights management: click the secondary menu to enter the third-level menu to display roles (basic permissions) and button permissions

Roles (basic permissions): divide into role groups and roles, assign menu permissions and add, delete, change and search permissions independently. (a user can have multiple roles)

Button permissions: assign button permissions to roles.

Button management: customize button management, maintain button shiro permission identification, etc.

Menu management: n-level custom menu, select menu icon, menu status display hidden (recursive processing)

Data dictionary: n-level, supporting multi-level classification. Built-in numbering, sorting, etc.

Log management: record user login and logout and some important operation records

Online management: websocket technology, real-time detection of online user list, statistics of the number of online, can force users offline the same user can only log in in one client

System users: add, delete, modify and check each basic user, export to excel table, delete in batch

Internal message: incoming and outgoing mailboxes, timely reminders made by websocket technology and communication technology, and voice prompt letters can be configured.

System settings: modify system name, number of messages per page, mail service configuration, internal message configuration

10. Performance monitoring: drudi monitors the performance of various services, SQL monitoring, SQL firewall, URL monitoring, SPRING monitoring, SESSION monitoring, etc.

IV: system tools services-

Code generation: generate complete module code, and retain the generation record template, reusable (super powerful development weapon)

Forward generation: generate complete modules, html pages, processing classes, mapper layer, service layer, myabaits xml table building sql script, etc.

Reverse generation: modules that arbitrarily connect to other databases (mysql, oracle, sqlserver) and reflect the cost system according to the table

2 template management: code online editor, manage templates, save editing records, one-click restore, code generator is like a tiger

5: IM instant messaging service-

Friend management: search, add, delete, block friends, view friend profiles

Friend grouping: custom friend grouping

My group: create groups, search for applications to join other people's groups, kick out group members, manage group chats

Communication module single chat group chat, send pictures, send files, offline messages, keep chat records.

VI: database management services--

Database backup: can back up single table (not supported by sqlserver), entire library, support local and remote backup (java interface programming technology, socket programming technology)

Backup timer: quartz powerful task scheduling, multi-thread backup database, task startup and shutdown asynchronous operation

Database restore: historical backup records, restore database or single table (not supported by sqlserver), statistics backup time and file size

SQL Editor: a powerful SQL editor that supports editing complex query statements, generating dynamic reports, and exporting excel

Seven: OA office services--

Leave application: add leave request, follow the workflow leave model process

Eight: table synchronization service--

According to the business requirements, it is necessary to synchronize the table data between microservices, so this intermediate service is used.

Menu permissions: different menu permissions assigned to each role, different menus seen by each role, N-level menus

Button permissions: assign different roles and different functional permissions independently, add, delete, change and search permissions to different menus, and customize button management.

Multi-user privilege management background is supported, and permissions are specific to different menus and different buttons (a user can have multiple roles)

Technical point--

Import and export excel files (applied to system users)

2 generate word file (apply to the doc document generated by the code generator)
