Microservice public module (public subproject) construction process

In microservice projects, many duplicate entity classes, public methods, static variables and the like cannot be avoided. We need to build a public module to remove code redundancy

• Step 1: Create a new module and select the maven project (right-click the parent project gulimall—select New—select Module)
  

• Step 2: Configure pom.xml (import public dependencies), public methods
  

• Step 3: install

• Step 4: Introduce common modules into other microservices
