在我的项目中，我使用了 spring-boot 和嵌入式 Mongo Db，查看我的 pom.xml 文件:

当我第一次运行“mvn spring-boot:run”时，我的 maven 开始下载 MongoDB 二进制文件，在开发环境中没问题，但是当我使用“java -jar”运行 jar 项目(由 mvn clean install 生成)时我看到另一个开始下载 MongoDB 二进制文件。

所以...为了在我使用“java -jar”运行时避免下载，我想在我的项目 jar 中插入 MongoDB 二进制文件。

这可能吗？

谢谢大家。

最佳答案

从 spring-boot-starter-data-mongodb 中排除 mongo 依赖:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-mongodb</artifactId>
    <exclusions>
         <exclusion>
               <groupId>org.mongodb</groupId>
               <artifactId>mongodb-driver</artifactId>
         </exclusion>
    </exclusions>
</dependency>
