In this issue, the editor will bring you about how to customize spring-boot-starter. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

Custom spring-boot-starter

Springboot stipulates that the package on the general official website is called spring-boot-start-xxx (spring-boot-start-web).

The naming rules for individuals or third parties are: xxx-spring-boot-start (pagehelper-spring-boot-start)

Imitate pageHelper to create springboot package

Currently, we create a maven to create a project in order to import the jar package. The springboot project packages jar as an executable file by default. If you want to change it to an imported jar package, you need to change it to

Org.springframework.boot spring-boot-maven-plugin exec

Check the details without much explanation.

General package structure Information / pageHelper introduction package structure is-|-pagehlper.jar |-pagehelper-spring-boot-autoconfigure.jar |-pagehelper-spring-boot-starter.jar / / Custom package structure is-white-spring-boot |-white-spring-boot-autoconfigure automatic configuration class |-white-spring-boot-starter load class |-white-core core logic white-spring-boot-starter

The project is currently empty, and the file resources/META-INF/spring.provides is added to the main content

The references in pageHelper are as follows

Provides: pagehelper-spring-boot-autoconfigure,pagehelper,mybatis-spring-boot-autoconfigure,mybatis,mybatis-spring

Org.springframework.boot.autoconfigure.EnableAutoConfiguration=\ com.apple.WhiteAutoConfiguration

Create com.apple.WhiteAutoConfiguration

Configuration@EnableConfigurationProperties (WhiteProperties.class) public class WhiteAutoConfiguration {} @ ConfigurationProperties (prefix = "white") @ Getter@Setterpublic class WhiteProperties {private Properties properties = new Properties (); public Properties getProperties () {return this.properties;} private String userName; private Integer age;}
