springboot自定义starter并上传至公网调用

1.目录结构

2.新建DemoProperties实体类

package com.focusmedia.starter.Demo.properties;

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

/**
 * 在.properties中需要配置的字段
 * 配置示例：
 *      demo.sayWhat=hello
 *      demo.toWho=wshy
 *
 * @title: DingProperties
 * @Author: wshy
 */
//将实体类注册为bean
@Component
//将实体类与properties配置文件对应
@ConfigurationProperties(prefix = "demo")
public class DemoProperties {

    private String sayWhat;
    private String toWho;

    public String getSayWhat () {
        return sayWhat;
    }

    public void setSayWhat (String sayWhat) {
        this.sayWhat = sayWhat;
    }

    public String getToWho () {
        return toWho;
    }

    public void setToWho (String toWho) {
        this.toWho = toWho;
    }

}

3.新建DemoService类

package com.focusmedia.starter.Demo.service;
/**
 * 描述：随便定义一个Service
 *      service在config中进行配置注入
 * @Author wshy
 * @Version V1.0
 **/
public class DemoService {

    public String sayWhat;
    public String toWho;

    public DemoService(String sayWhat, String toWho){
        this.sayWhat = sayWhat;
        this.toWho = toWho;
    }
    public String say(){
        return this.sayWhat + "!  " + toWho;
    }
}

4.新建DemoConfig配置类

package com.focusmedia.starter.Demo.config;

import com.focusmedia.starter.Demo.properties.DemoProperties;
import com.focusmedia.starter.Demo.service.DemoService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.autoconfigure.condition.ConditionalOnClass;
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;

/**
 * 描述：配置类
 *
 * @Author wshy
 * @Version V1.0
 **/
@Configuration
@EnableConfigurationProperties(DemoProperties.class)
//条件注解，用于控制配置类是否生效
@ConditionalOnProperty(
        prefix = "demo",    //配置文件前缀
        name = "isopen",    //配置的名字
        havingValue = "true"//与配置中对比的对比值，当两个值想通过返回true，配置类生效
)
//条件注解，作用在类上，只有在classpath包含DemoService时，类DemoConfig中的所有@bean标注的方法才可以注入容器
@ConditionalOnClass(DemoService.class)
public class DemoConfig {
    @Autowired
    private DemoProperties demoProperties;

    @Bean(name = "demo")
    public DemoService demoService(){
        return new DemoService(demoProperties.getSayWhat(), demoProperties.getToWho());
    }
}

5.新建spring.factories

在resource下面新建MATE-INF文件夹，并新建spring.factories配置文件

#-------starter自动装配---------
org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
  com.focusmedia.starter.Demo.config.DemoConfig

6.上传到git

7.Jitpack生成maven依赖

https://jitpack.io/#com.gitee.wsy-xzp/ding-spring-boot-starter/0.0.3

8.其他springboot服务中调用

9.测试调用

1.application.yml中加入starter需要的配置信息

2.启动服务，并调用接口测试
