Java project: Lawyer consultation management system (java + Spring + springmvc + mybatis + SSM + MySQL)

Spring+SpringMvc+Mybatis Framework implementation , This interface uses jsp The page matches DispalyTag Tag library , This tag library is very old , But it's easy to understand , The simple understanding is to optimize table Tables make tables look better , Better echo data . The system has three roles :

Administrators ： Carousel Map Management 、 User management 、 Lawyer management 、 Historical case management 、 Types of historical cases 、 Firm news 、 Personal information management

The lawyer ： Case consultation management 、 Personal center 、 message management 、 Send information management

The front desk user ： Sign in 、 register 、 Check the case of the firm 、 Counsel 、 View lawyer 、 Check out the news 、 Case consultation, etc

This system is worth learning , A lot of function , Project catalog standards , Simple and easy to understand , Lay the groundwork for adding functions in the future . Code quality can , I can add more functions, and the design is perfect , If you want to add functions after purchase, you can contact me , Can give some guidance , If the functions here are done one by one, they must be greatly improved , Very progressive , Actual combat is the best performance to show Technology .
