SpringBoot自定义Starter
CaptainCats 人气:0starter起步依赖
starter起步依赖是springboot一种非常重要的机制,
它打包了某些场景下需要用到依赖,将其统一集成到starter,
比如,
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency>
这就是一个starter,你可以把它看做一个外部外部项目,注意:是外部项目。
starter命名规则
springboot提供的starter以spring-boot-starter-x的方式命名,
自定义starter以x-spring-boot-starter的方式命名,
以区分springboot生态提供的starter。
自定义starter
new module
mystarter-spring-boot-starter
maven项目
添加依赖
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-autoconfigure</artifactId> <version>2.2.9.RELEASE</version> </dependency>
load maven changes
simplebean
package com.duohoob.bean; import org.springframework.boot.autoconfigure.EnableAutoConfiguration; import org.springframework.boot.context.properties.ConfigurationProperties; /** * 这两个都是非@Component注解, * 否则springboot启动时会直接被加载进spring容器 */ @EnableAutoConfiguration @ConfigurationProperties(prefix = "simplebean") public class SimpleBean { private String id; private String name; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } @Override public String toString() { return "SimpleBean{" + "id='" + id + '\'' + ", name='" + name + '\'' + '}'; } }
自动配置类
package com.duohoob.config; import com.duohoob.bean.SimpleBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; @Configuration public class MyAutoConfiguration { @Bean public SimpleBean simpleBean() { return new SimpleBean(); } }
META-INF\spring.factories
在resources下创建META-INF\spring.factories
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.duohoob.config.MyAutoConfiguration
在spring-boot-mytest中引入mystarter-spring-boot-starter
<dependency> <groupId>com.duohoob</groupId> <artifactId>mystarter-spring-boot-starter</artifactId> <version>1.0-SNAPSHOT</version> </dependency>
load maven changes
添加配置
在spring-boot-mytest的src/main/resources/application.properties中添加配置
通过@Autowired引用
package com.duohoob.springbootmytest.controller; import com.duohoob.bean.SimpleBean; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class TestController { @Autowired private SimpleBean simplebean; @RequestMapping("/test") public String test() { return simplebean.toString(); } }
