这篇文章主要介绍了如何使用SpringBoot自定义starter,具有一定借鉴价值,感兴趣的朋友可以参考下,希望大家阅读完这篇文章之后大有收获,下面让小编带着大家一起了解一下。
springboot一种全新的编程规范,其设计目的是用来简化新Spring应用的初始搭建以及开发过程,SpringBoot也是一个服务于框架的框架,服务范围是简化配置文件。
工程由xxx-sprig-boot-starter和xxx-sprig-boot-starter-configure两个模块组成;

xxx-sprig-boot-starter模块
只用来做依赖导入
依赖于 xxx-sprig-boot-starter-configure模块,没有实际代码
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.ander</groupId> <artifactId>ander-spring-boot-starter</artifactId> <version>1.0-SNAPSHOT</version> <!--依赖ander-spring-boot-starter-configure工程--> <dependencies> <dependency> <groupId>com.ander</groupId> <artifactId>ander-spring-boot-starter-configure</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> </dependencies> </project>

xxx-sprig-boot-starter-configure模块
专门自动配置模块
依赖于spring-boot-starter-web
<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.3.10.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <groupId>com.ander</groupId> <artifactId>ander-spring-boot-starter-configure</artifactId> <version>0.0.1-SNAPSHOT</version> <name>ander-spring-boot-starter-configure</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> </project>
/**
* Service层

*/
public class HelloService {
private HelloServiceProperties helloServiceProperties;
public String helloService(String name) {
return helloServiceProperties.getPrefix() + " "+ name + " " + helloServiceProperties.getSuffix();
}
public HelloServiceProperties getHelloServiceProperties() {
return helloServiceProperties;
}
public void setHelloServiceProperties(HelloServiceProperties helloServiceProperties) {
this.helloServiceProperties = helloServiceProperties;
}
}/**
* 属性配置类
*
* @Author: Ander
* @Date: 2021-05-04
*/
@ConfigurationProperties(prefix = "com.ander")
public class HelloServiceProperties {
private String prefix = "hi";
private String suffix = "hello world";
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;
}
}@EnableConfigurationProperties({HelloServiceProperties.class})作用:让xxxProperties生效加入到容器中
/**
* 自定义starter自动配置类
*
* @Date: 2021-05-04
*/
@Configuration
@ConditionalOnWebApplication // 指定web应用才生效
@EnableConfigurationProperties({HelloServiceProperties.class})
public class HelloServiceAutoConfigure {
@Autowired
private HelloServiceProperties helloServiceProperties;
@Bean
public HelloService helloService() {
HelloService helloService = new HelloService();
helloService.setHelloServiceProperties(helloServiceProperties);
return helloService;
}
}
注意先安装xxx-spring-boot-starter-configure,再安装xxx-spring-boot-starter

/**

@RestController
public class StarterTestController {
@Autowired
private HelloService helloService;
@GetMapping("hello")
public String hello(String name) {
return helloService.helloService(name);
}
}server.port=8888
com.ander.prefix=HI
com.ander.suffix=HELLO WORLD
