本文介绍了使用Idea搭建Spring Boot启动器项目的步骤。先建立empty project，添加自动配置和启动器两个module，启动器依赖自动配置。接着说明了项目结构和内部代码，最后进行测试，新建Spring Boot项目引入启动器，添加配置项，通过浏览器或Postman请求获得响应。

1、idea建立一个empty project。

2、添加两个module，一个是自动配置（maven工程），一个是启动器（springboot工程），启动器依赖自动配置。

3、项目结构

4、内部代码

1）spring-boot-starter-autoconfigurer module：

package com.wms.starter;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.context.properties.EnableConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

/**
 * @author:wangmingsai
 * @date:2018/8/28
 * @desc:
 */
@Configuration
@EnableConfigurationProperties(HelloProperties.class)
public class HelloAuto {
    @Autowired
    HelloProperties helloProperties;

    @Bean
    public HelloService helloService() {
        HelloService helloService = new HelloService();
        helloService.setHelloProperties(helloProperties);
        return helloService;
    }
}

package com.wms.starter;

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

/**
 * @author:wangmingsai
 * @date:2018/8/28
 * @desc:
 */
@ConfigurationProperties(prefix = "wms.hello")
public class HelloProperties {
    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

package com.wms.starter;

/**
 * @author:wangmingsai
 * @date:2018/8/28
 * @desc:
 */
public class HelloService {

    HelloProperties helloProperties;

    public String hello() {
        return "hello" + helloProperties.getName();
    }

    public HelloProperties getHelloProperties() {
        return helloProperties;
    }

    public void setHelloProperties(HelloProperties helloProperties) {
        this.helloProperties = helloProperties;
    }
}

spring.factories文件:

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.wms.starter.HelloAuto

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.wms</groupId>
	<artifactId>spring-boot-starter-autoconfigurer</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>jar</packaging>

	<name>spring-boot-starter-autoconfigurer</name>
	<description>Demo project for Spring Boot</description>

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>2.0.4.RELEASE</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>

	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
	</properties>

	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter</artifactId>
		</dependency>

	</dependencies>

</project>

2）springbootstarter：

启动器比较简单，只有pom文件，引入自动配置即可。

<?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>wms</groupId>
    <artifactId>springboot-starter</artifactId>
    <version>1.0-SNAPSHOT</version>
    <dependencies>
        <dependency>
            <groupId>com.wms</groupId>
            <artifactId>spring-boot-starter-autoconfigurer</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>
    </dependencies>

</project>

5、测试，新建springboot项目，pom文件中引入启动器

        <dependency>
            <groupId>wms</groupId>
            <artifactId>springboot-starter</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>

application.properties添加配置项

wms.hello.name=chenzz

测试controller：

package com.wms.teststarter;

import com.wms.starter.HelloService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @author:wangmingsai
 * @date:2018/8/29
 * @desc:
 */
@RestController
public class controller {

    @Autowired
    HelloService helloService;

    @GetMapping("hello")
    public String hello(){
        return helloService.hello();
    }
}

通过浏览器或者postman请求，获得响应：
