本文介绍了使用来自 Maven 本地依赖项的类 - 我错过了什么?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个名为 Auth 的服务:

I have a service called Auth:

<groupId>rcs.auth</groupId>
<artifactId>Auth</artifactId>
<version>1.0-SNAPSHOT</version>

我有一个名为 ImageRepo 的服务，它使用 Auth.这是 ImageRepo 的 pom:

And I have a service called ImageRepo that uses Auth. This is ImageRepo's pom:

<dependencies>
    <dependency>
        <groupId>rcs.auth</groupId>
        <artifactId>Auth</artifactId>
        <version>1.0-SNAPSHOT</version>
    </dependency>
    ...
<dependencies>

它解决了，找到了依赖.但是当我尝试从 rcs.auth 导入类时，找不到任何类.我错过了什么?

It resolves, the dependency is found. But when I try to import classes from rcs.auth, none can be found. What am I missing?

这里是Auth制作的jar的内容.我想用粗体显示的类.

Here are the contents of the jar produced by Auth. The class I want to use it in bold.

我想使用的类是:BOOT-INF/classes/rcs/auth/utils/AuthUtils.class

The class I want to use is: BOOT-INF/classes/rcs/auth/utils/AuthUtils.class

已修复

我将此添加到 Auth 的 pom 中:

I added this to Auth's pom:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>2.2.3.RELEASE</version>
    <configuration>
        <classifier>exec</classifier>
    </configuration>
</plugin>

但现在我遇到了一个不同的问题……所有 Auth 的类都可用于 ImageRepo.我不希望那样，我只希望某些类/包是公开的.我怎样才能做到这一点?

But now I have a different problem... ALL of Auth's classes are available to ImageRepo. I don't want that, I only want certain classes/packages to be public. How can I accomplish that?

推荐答案

您不能使用 Spring Boot 应用程序作为依赖项.

You cannot use a Spring Boot app as dependency.

如果您需要库 JAR，请构建一个简单的 JAR，而不是 Spring Boot 应用程序.

If you need a library JAR, build a simple JAR, not Spring Boot app.
