Question

我有一个大项目，包括几个小模块：

core.jar：包含实体＆amp;数据jpa存储库，使用spring-boot-starter-data-jpa
api.jar：包含所有其余的控制器，取决于core.jar并使用spring-boot-starter-web
web.war：入口点，包含配置并按照指南从可执行jar转换为war：http://spring.io/guides/gs/convert-jar-to-war/

一切运作良好，唯一的问题是战争档案非常大，关于＆gt;当前代码库为300MB（非常小，只有一些控制器，很少实体）。我做了一些调查，发现core.jar＆amp; api.jar包含依赖项，web.war也会再次包含那些依赖项包含自己的依赖项。

我们是否还有构建jar，没有依赖的war，让他们在生产机器上首次启动时下载依赖项？或者依赖包依赖，所以在增量部署中，我们不需要重新上传整个内容吗？

此致

更新1：

问：我需要core.jar＆amp; api.jar是可执行的。

答：不，我不需要它，但我也不想列出包含spring-boot-starter-data-jpa或{{我可以拥有的所有差异依赖关系1}}

Answer 1

如果使用Maven构建项目，则可以使用依赖项范围 http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Scope

<dependency>
  <groupId>group-c</groupId>
  <artifactId>artifact-b</artifactId>
  <version>1.0</version>
  <type>war</type>
  <scope>runtime</scope>
</dependency>

和排除

<dependency>
  <groupId>group-a</groupId>
  <artifactId>artifact-a</artifactId>
  <version>1.0</version>
  <exclusions>
    <exclusion>
      <groupId>group-c</groupId>
      <artifactId>excluded-artifact</artifactId>
    </exclusion>
  </exclusions>
</dependency>

因此war项目可以排除依赖项，jar项目可以使用编译时依赖。

Answer 2

如果你不需要核心和api JAR可执行，只需从那些poms中删除spring-boot-maven-plugin。在STS IDE自动生成的pom.xml中，您可以删除整个<build/>部分，即

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>
