具有Spring启动的多模块Web应用程序maven架构

Question

我正在构建一个包含多个模块的Web应用程序，我想将每个模块拆分为一个项目。这是我第一次尝试这样做，我曾经在一个项目中创建应用程序，我不想用错误的架构开始开发。我想做的事：

--Maven parent project
    -- main app: Spring boot, Database connection, authentication, user management.
    -- Module 1,2 .. n: modules, repositories, controllers

因此，我们的想法是在用例视角下按功能拆分项目。问题是：这个架构能否正常运行，如何使用maven进行配置？

Answer 1

你需要这样的东西：

1）有一个父pom将它们全部保存在一起，这是你的父母有一个spring-boot的父母：

<?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>

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.4.3.RELEASE</version>
    </parent>

    <groupId>com.essexboy</groupId>
    <artifactId>boot-parent</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <modules>
        <module>boot-library</module>
        <module>boot-web</module>
    </modules>

</project>

2）拥有任意数量的库模块：

<?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>

  <parent>
    <artifactId>boot-parent</artifactId>
    <groupId>com.essexboy</groupId>
    <version>1.0-SNAPSHOT</version>
  </parent>

  <artifactId>boot-library</artifactId>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>
  </dependencies>

</project>

3）然后根据需要使用尽可能多的spring boot模块从同一个项目中获取所需的库：

<?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>

    <parent>
        <artifactId>boot-parent</artifactId>
        <groupId>com.essexboy</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>

    <artifactId>boot-web</artifactId>

    <dependencies>
        <dependency>
            <groupId>com.essexboy</groupId>
            <artifactId>boot-library</artifactId>
            <version>${project.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!-- tag::actuator[] -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <!-- end::actuator[] -->
        <!-- tag::tests[] -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <!-- end::tests[] -->
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
