Starter of SpringBoot

  java, spring, springboot

Order

SpringBoot’s starter is mainly used to simplify dependencies. This article is mainly divided into two parts, one is to list some starter’s dependencies, the other is to teach you to write a starter yourself.

How to Write starter

Main steps

  • 1. Select the existing starters and expand on this basis.
  • 2. Create an automatic configuration file and set the contents in META-INF/spring.factories.
  • 3. Publish your starter

Add dependency management

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>${spring.boot.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
</dependencyManagement>

Add starter’s own dependencies

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
</dependencies>

New configuration

@Configuration
@ComponentScan( basePackages = {"com.codecraft.actuator"} )
public class WebAutoConfiguration {

    /**
     * addViewController方法不支持placeholder的解析
     * 故在这里用变量解析出来
     */
    @Value("${actuator.web.base:}")
    String actuatorBase;

//    @Bean
//    public ActuatorNavController actuatorNavController(){
//        return new ActuatorNavController();
//    }

    @Bean
    public WebMvcConfigurerAdapter configStaticMapping() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addViewControllers(ViewControllerRegistry registry) {
                //配置跳转
                registry.addViewController(actuatorBase+"/nav").setViewName(
                        "forward:/static/nav.html");
            }

            @Override
            public void addResourceHandlers(ResourceHandlerRegistry registry) {
                registry.addResourceHandler("/static/**").
                        addResourceLocations("classpath:/static/");
            }
        };
    }

}
