Reference Address:
Maven constructed using Java polymeric engineering, the following structure:
Use mybatis-generator can create pojo, mapper, so we put the configuration file foodie-dev-mapper of the folder
1, first configuration for pom.xml introduced mybatis-generator associated jar package
<! - The following is used to configure the mybatis.generator ->
<Build>
<a finalName> Foodie-dev-Mapper </ a finalName>
<the pluginManagement> <! - Lock Down plugins versions to Avoid the using Maven Defaults (On May BE to parent POM Moved) ->

<-! geelynote Maven plug-core plug of -complier the default compiler supports only the Java 1.4 , and therefore need to add support for high version jre configuration, coupled with the increase in pom.xml inside compile widget ->

otherwise, can be local, but later released, jar packets are missing ->

Remarks:
Folder name and configuration file must be consistent
3, click on the right maven code generation tools
4, to be used in the polymerization to generate the project file, mybaitis also need to be arranged in the application.yml
mybatis: mapper-locations: classpath*:mappers/*.xml
This is necessary, otherwise there will be operating mapper and xml do not match
