2. Configure basic project structure

(1) Create a bean bag and related entities in the project package class

Custom database, creating entity classes and associated attributes corresponding to each table in accordance with, getXX () and setXX () method

(2) create a packet DAO and corresponding interfaces dao

DAO class integrated JpaRepository, provides a variety of common functions CRUD and paging.

(3) create a packet service and the corresponding service class

(4) create a controller and controller package websites corresponding to each function

(5) to start writing class

(7) configuration exception handling, interceptor, the filter

Creating exception class exception handling package and write

Mainly when dealing delete the parent class information, because there are foreign key constraints, resulting in constraint violations

Create a filter bag, realm package, configure shiro

Creating interceptor package and write interceptor class

3. Configuration Properties Files

(1) Configuration application.properties

4. Import static resources

Create your own webapp directory. In general, the agreement, the static resources springboot will be in the static directory, but we are on the webapp directory, because we need to do to upload a picture, if it is placed under static, you can not upload pictures after accessed, placed under the webapp, after upload, it can be accessed immediately.

Three: Run

1. Start redis

2. Start project
