java - 带有 Spring starter 多模块项目的大 war 文件

Question

我有一个大项目，由几个小模块组成:

• core.jar:包含实体和数据 jpa 存储库，使用 spring-boot-starter-data-jpa
• api.jar:包含所有其余 Controller ，依赖于 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/

一切正常，唯一的问题是 war 文件非常大，在当前代码库中大约 > 300MB(非常小，只有一些 Controller ，很少实体)。我做了一些调查，发现 core.jar 和 api.jar 包含依赖项，web.war 也再次包含这些依赖项，其中包括他自己的依赖项。

我们是否可以构建没有依赖项的 jar、war 并让它们在生产计算机上首次启动时下载依赖项？或者把依赖包分开，这样在增量部署的时候，我们就不需要重新上传整个东西了？

问候，

更新1:

问:我需要 core.jar 和 api.jar 才能执行吗？

A:不，我不需要它，但我也不想列出所有不同的依赖项，这些依赖项是我可以通过包含 spring-boot-starter 获得的-data-jpa 或 spring-boot-starter-web

Answer 1

如果您不需要核心和 api JAR 可执行，只需从这些 poms 中删除 spring-boot-maven-plugin 即可。在自动生成的pom.xml中从 STS IDE 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>
