减少 Spring Boot 可执行 jar Angular App 的磁盘空间

Question

Maven 项目：SpringBoot 有一个 SpringBoot 启动类。 “资源/公共”文件夹中的 Angular 网站。

应用程序启动并提供来自公共文件夹的 index.html。

我想减小 spring boot 应用程序的大小。我已经完成了 Angular 应用程序的修剪。

我在 SpringBoot 中有哪些选项可以只运行静态网站？我可以排除任何样板代码吗？

注意：这是一个 Maven 项目。

Answer 1

我能够在可执行 JAR 中保存 ~13MB

• 没有休眠的 SpringBoot 大约 14MB (5MB)
• Angular，删除 FONTS 文件夹为我节省了 ~8MB

我所做的是运行mvn dependency:tree

然后我查看了列表并通过使用排除更新 pom 来删除 Hibernate：

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>${spring.boot-version}</version>
                  <exclusions>
                    <exclusion>  <!-- declare the exclusion here -->
                      <groupId>org.hibernate</groupId>
                      <artifactId>hibernate-validator</artifactId>
                    </exclusion>
                  </exclusions> 
        </dependency>
