This article shows you how to customize starter in SpringBoot, which is concise and easy to understand, which will definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

1 create an empty project first (name yourself)

2 create two modules in the empty project created in step 1, as shown in the following figure

1) create the initiator module with the maven project my initiator name is mao-spring-boot-starter

The pom.xml is as follows

4.0.0com.mao.startermao-spring-boot-starter1.0-SNAPSHOT UTF-8 UTF-8 1.8 com.mao-starter mao-spring-boot-starter-autoconfigurer 0.0.1-SNAPSHOT

2) create an automatic configuration module. The name I created is: mao-spring-boot-starter-autoconfigurer, as shown in the following figure! [] (https://oscimg.oschina.net/oscnet/b7c0a779402394cb5783f3f2eae7a5ce0bc.jpg)pom.xml is shown below

4.0.0 org.springframework.boot spring-boot-starter-parent 1.5.21.RELEASE com.mao-startermao-spring-boot-starter-autoconfigurer0.0.1-SNAPSHOTmao-spring-boot-starter-autoconfigurerDemo project for Spring Boot UTF-8 UTF-8 1.8

Org.springframework.boot spring-boot-starter

3 create three classes in the following figure

HelloProperties.java / / attribute class

Package com.maostarter.mao

Import org.springframework.boot.context.properties.ConfigurationProperties

@ ConfigurationProperties (prefix = "map.hello")

Public class helloProperties {

Public String prefix;public String getPrefix () {return prefix;} public void setPrefix (String prefix) {this.prefix = prefix;} public String getSuffix () {return suffix;} public void setSuffix (String suffix) {this.suffix = suffix;} private String suffix

}

HelloService.java / / classes that provide services to the outside

Public class HelloService {

HelloProperties helloPropertie;public helloProperties getHelloPropertie () {return helloPropertie;} public void setHelloPropertie (helloProperties helloPropertie) {this.helloPropertie = helloPropertie;} public String sayHelloMao (String name) {return helloPropertie.getPrefix () +'*'+ name+helloPropertie.getSuffix ();}

}

HelloServiceAutoConfiguration.java / / Service automatic injection class

@ Configuration

@ ConditionalOnWebApplication / / web application takes effect

@ EnableConfigurationProperties (helloProperties.class)

Public class helloServiceAutoConfiguration {

@ AutowiredhelloProperties helloPropertie;@Beanpublic HelloService helloService () {HelloService service = new HelloService (); service.setHelloPropertie (helloPropertie); return service;}

}

4 configure spring.factories file, as shown in the following figure

Spring.factories

Org.springframework.boot.autoconfigure.EnableAutoConfiguration=\

Com.maostarter.mao.helloServiceAutoConfiguration

5 how to generate starter, there are various problems in this process, such as the wrong version of jdk and the problem of maven version. If there are problems, first read the console information carefully.

Don't go to Baidu whenever something goes wrong.

6 Test the custom starter you just created to create a springBoot project

The pom.xml is as follows

4.0.0 org.springframework.boot spring-boot-starter-parent 2.1.6.RELEASE com.autostart.testautostart0.0.1-SNAPSHOTautostartDemo project for Spring Boot 1.8 org.springframework.boot spring-boot-starter-web com .mao.starter mao-spring-boot-starter 1.0-SNAPSHOT org.springframework.boot spring-boot-starter-test test Org.springframework.boot spring-boot-maven-plugin

6 copy the previously configured properties file as shown below

7 create a test case

@ Controller

Public class HelloController {

@ Autowired HelloService helloService; @ ResponseBody@RequestMapping ("/ hello") public String Hello () {return helloService.sayHelloMao ("");}

}

8 the test results are shown in the following figure
