二、创建springboot-web

(1) 右键点击父工程 -> new -> Other… -> Maven -> Maven Module

Springboot分模块项目搭建的实现

(2) pom.xml

<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>
	<artifactId>springboot-web</artifactId>
	<packaging>jar</packaging>
	<njsame>springboot-web</name>
	<parent>
		<groupId>com.button</groupId>
		<artifactId>springboot-parent</artifactId>
		<version>0.0.1-SNAPSHOT</version>
	</parent>
	<!-- Web模块相关依赖 -->
	<dependencies>
		<dependency>
			<groupId>com.button</groupId>
			<artifactId>springboot-service</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-devtools</artifactId>
			<optional>true</optional>
			<scope>true</scope>
		</dependency>
	</dependencies>
	<!--只需在启动类所在模块的POM文件：指定打包插件 -->
	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-compiler-plugin</artifactId>
				<configuration>
					<source>1.8</source>
					<target>1.8</target>
				</configuration>
			</plugin>
			<plugin>
				<groupId>org.springframework.boot</groupId>
				<artifactId>spring-boot-maven-plugin</artifactId>
				<configuration>
					<jvmArguments>-Dfile.encoding=UTF-8</jvmArguments>
					<fork>true</fork><!-- 没有该配置，devtools 不生效 -->
				</configuration>
			</plugin>
		</plugins>
	</build>
</project>

解释：

pom文件中的如下配置：

<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-devtools</artifactId>
	<optional>true</optional>
	<scope>true</scope>
</dependency>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <!-- 没有该配置，devtools 不生效 -->
                <fork>true</fork>
            </configuration>
        </plugin>
    </plugins>
</build>

如上的两项配置，添加之后会打开springboot的热部署，这样每次修改文件之后，不用手动重新启动项目。配置热部署可以让项目自动加载变化的文件，省去的手动操作。(项目搭建好之后，启动项目，随便创建/修改一个文件并保存，会发现控制台打印 springboot 重新加载文件的log。)

三、创建springboot-service

参照如上创建方式

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	<artifactId>springboot-service</artifactId>
	<packaging>jar</packaging>
	<name>springboot-service</name>
	<parent>
		<groupId>com.button</groupId>
		<artifactId>springboot-parent</artifactId>
		<version>0.0.1-SNAPSHOT</version>
	</parent>

	<dependencies>

	private static final long serialVersionUID = 1L;
	private Integer id;

	}
}

3、springboot-service

@Service
public class UserServiceImpl implements UserService {
	
	@Autowired

	<root level="DEBUG">

		<appender-ref ref="FILE" />
	</root>
</configuration>

七、完整项目结构如下：

Springboot分模块项目搭建的实现

注：一个项目从开发，测试再到生产，可能会使用到不同的配置信息，每次去修改application.yml文件中的信息就显得特别麻烦，可以使用如下方式解决。

比如项目运行环境开发(dev)，测试(test)，生产(prod)，我们可以在src/main/resources文件夹下创建如下四个文件：

application-dev.yml

server:
    servlet:
        context-path: /button-dev
    port: 8080
    uri-encoding: utf-8

application-test.yml

server:
    servlet:
        context-path: /button-test
    port: 8081
    uri-encoding: utf-8

application-prod.yml

server:
    servlet:
        context-path: /button-prod
    port: 8082
    uri-encoding: utf-8

这三个文件配置好项目不同环境的配置信息

application.yml文件配置如下：

spring:
    profiles:
        active: dev

解释：active后可以配置dev、test、prod，不同的配置会去加载不同的配置信息，这样就不用来回修改配置信息了。
