当初各种自定义的 starter 不足为奇,兴许就须要本人来自定义一个 starter 了。学习一下 starter 的构建必备
starter- 定义
首先须要自顶一个配置 bean
package com.zhao.starter;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
@EnableConfigurationProperties(StarterBean.class)
@ConfigurationProperties(prefix = "starterbean")
public class StarterBean {
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 "StarterBean{" +
"id='" + id + '\'' +
", name='" + name + '\'' +
'}';
}
}
而后须要通过 Springboot 主动注入的注解,以及 Spring spi 的 spring.factories 将配置 bean 退出主动配置的治理
@Configuration
@ConditionalOnClass
public class StartBeanAutoConfiguration {
static {System.out.println("custom auto configuration init");
}
@Bean
public StarterBean starterBean(){return new StarterBean();
}
}
资源目录下新建 META-INF 文件夹下 spring.factories 文件,
org.springframework.boot.autoconfigure.EnableAutoConfiguration=com.zhao.starter.StartBeanAutoConfiguration
pom 文件
<?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.zhao</groupId>
<artifactId>starter-demo</artifactId>
<version>1.0-SNAPSHOT</version>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-autoconfigure</artifactId>
<version>2.2.2.RELEASE</version>
</dependency>
</dependencies>
</project>
应用 maven install 之后就能够在新建我的项目时应用了。
starter 应用测试
pom 定义
<?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">

<artifactId>spring-boot-starter-test</artifactId>
<version>2.2.2.RELEASE</version>
<scope>test</scope>
</dependency>
</dependencies>
</project>
启动类
@SpringBootApplication
public class StarterUseApplication {public static void main(String[] args) {SpringApplication.run(StarterUseApplication.class,args);
}
}
配置 starter 须要的 bean 的配置
starterbean.id=test123
starterbean.name=zhaozhen
测试类
@RunWith(SpringRunner.class)
@SpringBootTest(classes = StarterUseApplication.class)
public class StarterUseTest {
@Autowired
StarterBean starterBean;
@Test
public void starUse(){System.out.println(starterBean);
}
}
测试后果,失常应用
