spring boot 自定义 start pom

1.属性配置

package com.module.other;

import org.springframework.boot.context.properties.ConfigurationProperties;

@ConfigurationProperties(prefix = "hello")
public class HelloServiceProperties {

	private static final String MSG = "world";
	
	private String msg = MSG;

	public String getMsg() {
		return msg;
	}

	public void setMsg(String msg) {
		this.msg = msg;
	}
}

2.判断依据类

package com.module.other;

public class HelloService {

	private String msg;

	public String getMsg() {
		return msg;
	}

	public void setMsg(String msg) {
		this.msg = msg;
	}
	
	
}

3.自动配置类

package com.module.other;

import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean;
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
@EnableConfigurationProperties(HelloServiceProperties.class)
@ConditionalOnClass(HelloService.class)
@ConditionalOnProperty(prefix = "hello", value = "enabled", matchIfMissing = true)
public class HelloServiceAutoConfiguration {

	private HelloServiceProperties helloServiceProperties;
	
	@Bean
	@ConditionalOnMissingBean(HelloService.class)
	public HelloService helloService() {
		HelloService helloService = new HelloService();
		helloService.setMsg(helloServiceProperties.getMsg());
		return helloService;
	}

}

4.注册配置

在src/main/resources下新建META-INF/spring.factories

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.module.other.HelloServiceAutoConfiguration
