说明
命名规约：
官方命名：
- spring-boot-starter-xxx
自定义命名：
xxx-spring-boot-starter
步骤
1、在idea中新建一个普通Maven模块：Jing-spring-boot-starter
2、新建一个Springboot模块：JIng-spring-boot-starter-aoutoconfigure
3、在starter中导入autoconfigure的依赖
<dependency> <groupId>com.lili</groupId> <artifactId>jing-springboot-starter-autoconfig</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency>
4、编写一个类用来测试
@ConfigurationProperties(prefix = "com.lili") public class HelloProperties { private String name; private int age; public void setName(String name){ this.name = name; } public String getName(){ return this.name; } public void setAge(int age){ this.age = age; } public int getAge(){ return this.age; } @Override public String toString() { return "HelloProperties{" + "name='" + name + '\'' + ", age=" + age + '}'; } }
public class HelloService { private HelloProperties helloProperties; public void setHelloProperties(HelloProperties helloProperties) { this.helloProperties = helloProperties; } public HelloProperties getHelloProperties() { return helloProperties; } public void show(){ System.out.println("你好，丽丽"); } }
5、编写一个配置类并注入bean进行测试
@Configuration @ConditionalOnWebApplication @EnableConfigurationProperties(HelloProperties.class) public class HelloServiceAutoConfiguration { @Autowired HelloProperties helloProperties; @Bean public HelloService helloService(){ HelloService helloService = new HelloService(); helloService.setHelloProperties(helloProperties); return helloService; } }
6、在resources编写一个自己的META-INF\spring.factories,内容如下
org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.lili.config.HelloServiceAutoConfiguration
7、新建一个Maven模块进行测试，需要导入自定义的启动器
<!--导入自定义的测试器进行测试--> <dependency> <groupId>com.lili</groupId> <artifactId>jing-springboot-starter</artifactId> <version>0.0.1-SNAPSHOT</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency>
8、编写Controller
@RestController public class HelloController { @Autowired HelloService helloService; @RequestMapping("/helloStart") public HelloService getMessage(){ return helloService; } }
9、在properties里面可以给属性赋值
com.lili.name=张三 com.lili.age=23
10、运行然后访问
到这里，我们自己定义的starter就成功啦！
