使用SpringBoot自定义starter详解

一、新建一个工程

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>

二、xxx-sprig-boot-starter-configure模块自动配置编码2.1 服务层编码

/** * Service层 * * @Author: Ander * @Date: 2021-05-04 */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; }}2.2 属性配置类编码

/** * 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; }}2.3 starter自动配置类编码

@EnableConfigurationProperties({HelloServiceProperties.class})作用：让xxxProperties生效加入到容器中

/** * 自定义starter自动配置类 * * @Author: Ander * @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; }}2.4 添加自动配置类到META-INF路径下

2.5 将工程安装到本地

注意先安装xxx-spring-boot-starter-configure，再安装xxx-spring-boot-starter

三、新建一个工程测试自定义starter3.1 编写controller层

/** * starter测试控制类 * * @Author: Ander * @Date: 2021-05-05 */@RestControllerpublic class StarterTestController { @Autowired private HelloService helloService; @GetMapping('hello') public String hello(String name) {return helloService.helloService(name); }}3.2 编写配置文件

server.port=8888com.ander.prefix=HIcom.ander.suffix=HELLO WORLD

四、测试结果4.1 使用starter默认配置

4.2 使用自定义配置
