项目目录结构：

创建多模块的springboot项目

父工程：pom工程，管理整个项目依赖的版本

主工程：war工程，管理整个项目的配置（数据库配置，springmvc配置等等）

公共模块：jar工程，管理整个项目的util

子模块：jar工程，项目会有多个这样的子模块，比如用户管理子模块、角色管理子模块

下面我们从0开始搭建一个简单的多模块项目，工程名 chem

STEP ONE：搭建父模块

新建maven项目：file >> new >> project >> maven project

创建多模块的springboot项目

创建好父工程后，导入maven依赖

<properties>
	<spring.boot.version>2.1.4.RELEASE</spring.boot.version>
	<mybatis.version>2.0.1</mybatis.version>
	<druid.version>1.1.5</druid.version>
	<lang.version>3.8</lang.version>
</properties>

<dependencyManagement>
	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-dependencies</artifactId>
			<version>${spring.boot.version}</version>
			<type>pom</type>
			<scope>import</scope>
		</dependency>

		<!-- mybatis -->
		<dependency>
			<groupId>org.mybatis.spring.boot</groupId>
			<artifactId>mybatis-spring-boot-starter</artifactId>
			<version>${mybatis.version}</version>
		</dependency>

		<!-- 连接池 -->
		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>druid</artifactId>
			<version>${druid.version}</version>
		</dependency>

		<!-- lang3工具包 -->
		<dependency>
			<groupId>org.apache.commons</groupId>
			<artifactId>commons-lang3</artifactId>
			<version>${lang.version}</version>
		</dependency>
	</dependencies>
</dependencyManagement>

<build>
	<plugins>
		<!-- jdk版本号 -->
		<plugin>
			<groupId>org.apache.maven.plugins</groupId>
			<artifactId>maven-compiler-plugin</artifactId>
			<configuration>
				<source>1.8</source>
				<target>1.8</target>
				<encoding>UTF-8</encoding>
			</configuration>
		</plugin>
	</plugins>
</build>

STEP TWO：创建公共模块 chem-common

创建多模块的springboot项目

编写pom文件

<dependencies>
	<dependency>
		<groupId>org.apache.commons</groupId>
		<artifactId>commons-lang3</artifactId>
	</dependency>
</dependencies>

STEP THREE：创建用户管理子模块

创建多模块的springboot项目

1：编写pom文件：

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

	<!-- mybatis -->
	<dependency>
		<groupId>org.mybatis.spring.boot</groupId>
		<artifactId>mybatis-spring-boot-starter</artifactId>
	</dependency>

	<!-- lang3 -->
	<dependency>
		<groupId>org.apache.commons</groupId>
		<artifactId>commons-lang3</artifactId>
	</dependency>

</dependencies>

2：添加公共模块依赖

鼠标右击chem-module-user项目 maven >> ADD Dependency（添加依赖）

创建多模块的springboot项目

3：执行完添加依赖操作后在pom文件中会多出一个依赖，代表OK

创建多模块的springboot项目

STEP FOUR：创建角色管理子模块

不在赘述，同上操作，名称是 chem-module-role

STEP FIVE：创建主工程

创建多模块的springboot项目

1：创建完项目，提示有错误

创建多模块的springboot项目

pom文件错误信息：web.xml is missing and <failOnMissingWebXml> is set to true

不要着急，添加好依赖，在设置<failOnMissingWebXml>false</failOnMissingWebXml>，错误就会消失

<dependencies>
	<!-- thymeleaf模板引擎 -->
	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-thymeleaf</artifactId>
	</dependency>
	<dependency>
		<groupId>com.github.theborakompanioni</groupId>
		<artifactId>thymeleaf-extras-shiro</artifactId>
		<version>2.0.0</version>
	</dependency>

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

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

	<!-- mybatis -->
	<dependency>
		<groupId>org.mybatis.spring.boot</groupId>
		<artifactId>mybatis-spring-boot-starter</artifactId>
	</dependency>

	<!-- mysql -->
	<dependency>
		<groupId>mysql</groupId>
		<artifactId>mysql-connector-java</artifactId>
	</dependency>

	<!-- test -->
	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-test</artifactId>
		<scope>test</scope>
	</dependency>

	<!-- 连接池 -->
	<dependency>
		<groupId>com.alibaba</groupId>
		<artifactId>druid</artifactId>
	</dependency>
</dependencies>

<build>
	<plugins>
		<plugin>
			<groupId>org.apache.maven.plugins</groupId>
			<artifactId>maven-war-plugin</artifactId>
			<version>2.6</version>
			<configuration>
				<failOnMissingWebXml>false</failOnMissingWebXml>
			</configuration>
		</plugin>
	</plugins>
	<finalName>chem</finalName>
</build>

2：OK，配置好pom，再引入公共模块、用户管理子模块和角色管理子模块

<dependency>
	<groupId>com.mote</groupId>
	<artifactId>chem-common</artifactId>
	<version>0.0.1-SNAPSHOT</version>
</dependency>
		
<dependency>
	<groupId>com.mote</groupId>
	<artifactId>chem-module-user</artifactId>
	<version>0.0.1-SNAPSHOT</version>
</dependency>
	
<dependency>
	<groupId>com.mote</groupId>
	<artifactId>chem-module-role</artifactId>
	<version>0.0.1-SNAPSHOT</version>
</dependency>

3：配置主项目

创建多模块的springboot项目

启动类：

@SpringBootApplication
public class ChemApplication extends SpringBootServletInitializer{

	public static void main(String[] args) {
		SpringApplication.run(ChemApplication.class, args);
	}
	
	//重写configure方法
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(ChemApplication.class);
    }

}

mysql配置

import javax.sql.DataSource;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;

@Configuration
@MapperScan(basePackages = "com.mote.dao", sqlSessionFactoryRef = "sqlSessionFactory")
public class DatasourceConfig {

	// classpath* 这个*很重要，支持扫描依赖项目的配置文件
	static final String MAPPER_LOCATION = "classpath*:mybatis/mappers/*.xml";

	@Primary
	// 表示这个数据源是默认数据源
	@Bean(name = "dataSource")
	@ConfigurationProperties(prefix = "spring.datasource.mysql")
	public DataSource myDataSource() {
		return DataSourceBuilder.create().build();
	}

	@Primary
	@Bean(name = "sqlSessionFactory")
	public SqlSessionFactory sqlSessionFactory(
			@Qualifier("dataSource") DataSource datasource) throws Exception {
		SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
		bean.setDataSource(datasource);
		bean.setConfigLocation(new ClassPathResource("mybatis/mybatis-config.xml"));
		bean.setMapperLocations(new PathMatchingResourcePatternResolver()
				.getResources(DatasourceConfig.MAPPER_LOCATION));
		return bean.getObject();
	}

	@Primary
	@Bean("sqlSessionTemplate")
	public SqlSessionTemplate mySqlsessiontemplate(
			@Qualifier("sqlSessionFactory") SqlSessionFactory sessionfactory) {
		return new SqlSessionTemplate(sessionfactory);
	}
}

springmvc相关配置

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;

/**
 * springmvc 功能拓展
 * 
 * @author Administrator
 *
 */
@Configuration
public class SpringMvcConfig extends WebMvcConfigurationSupport {

	/**
	 * 静态资源映射：配置配置资源路径
	 */
	@Override
	protected void addResourceHandlers(ResourceHandlerRegistry registry) {
		registry.addResourceHandler("/css/**").addResourceLocations(
				"classpath:/static/css/");
		registry.addResourceHandler("/js/**").addResourceLocations(
				"classpath:/static/js/");
		registry.addResourceHandler("/images/**").addResourceLocations(
				"classpath:/static/images/");
		super.addResourceHandlers(registry);
	}

	/**
	 * 拓展视图映射：跳过后台直接跳转
	 */
	@Override
	protected void addViewControllers(ViewControllerRegistry registry) {
        
		
		super.addViewControllers(registry);
	}

}

TestController

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class TestController {

	/**
	 * 跳转test页面
	 * @return
	 */
	@GetMapping("test")
	public ModelAndView toTest() {
		ModelAndView mv = new ModelAndView("test");
		return mv;
	}

}

mybatis全局配置文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	<settings>
		<!-- 开启驼峰命名规则 -->
		<setting name="mapUnderscoreToCamelCase" value="true" />
		<!-- 开启打印sql -->
		<setting name="logImpl" value="STDOUT_LOGGING" />
		<!-- 开启二级缓存 -->
		<setting name="cacheEnabled" value="true" />
	</settings>
</configuration>

test.html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
<h1>THIS IS A MORE MODULE DEMO</h1>
</body>
</html>

springboot的配置文件（基础配置，都可以用上）

#mysql
spring.datasource.mysql.jdbc-url=jdbc:mysql://114.215.83.3:3306/chemLocation?serverTimezone=UTC&allowMultiQueries=true
spring.datasource.mysql.username=root
spring.datasource.mysql.password=123456
spring.datasource.mysql.driver-class-name=com.mysql.cj.jdbc.Driver
spring.datasource.mysql.type: com.alibaba.druid.pool.DruidDataSource

# port
server.port=8081

# contextPath
server.servlet.context-path=/chem

#log
logging.path=../logs

#thymeleaf
spring.thymeleaf.cache=false


#utf-8
spring.http.encoding.force=true
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
server.tomcat.uri-encoding=UTF-8

# tomcat & more springboot
spring.jmx.enabled=false

OK，最后启动springboot启动类，访问测试页面
