SpringBoot之Starter

codecraft

SpringBoot的starter主要用来简化依赖用的。本文主要分两部分,一部分是列出一些starter的依赖,另一部分是教你自己写一个starter。

如何自己写starter

主要步骤

  • 1、选择已有的starters,在此基础上进行扩展.
  • 2、创建自动配置文件并设定META-INF/spring.factories里的内容.
  • 3、发布你的starter

添加依赖管理

<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>

添加starter自己的依赖

<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>

新建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/");
            }
        };
    }

}

修改/META-INF/spring.factories

# AutoConfigurations
org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.codecraft.actuator.configuration.WebAutoConfiguration

发布

mvn clean install

引用

        <dependency>
            <groupId>com.codecraft</groupId>
            <artifactId>spring-boot-starter-actuator-web</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

启动访问

mvn spring-boot:run

访问
