如何将 Spring Boot Jar 导入其他 Spring Boot Jar Maven Base

Question

我需要帮助。我有 2 个 spring-boot-jar 项目 maven 基础，我想将第一个导入到第二个中，如图

我在 Config Spring-Boot 中导入 Util Jar 作为打击并运行 Spring Boot 但它显示错误

<dependency>
    <groupId>com.ballistic</groupId>
    <artifactId>adminutil</artifactId>
    <version>0.1</version>
</dependency>

[错误] 无法执行目标 org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project config: Compilation failure: Compilation failure:

Answer 1

您必须使用重新包装来满足此要求。

默认情况下，重新打包目标会将原始工件替换为 重新包装的。对于代表的模块来说，这是一种理智的行为 一个应用程序，但如果您的模块被用作另一个模块的依赖项， 您需要为重新包装的分类器提供分类器。

原因是应用程序类被打包在 BOOT-INF/classes 使依赖模块无法加载重新打包的 jar 的类。如果是这种情况，或者您更愿意保留 原始工件并将重新包装的工件附加到不同的工件上 分类器，配置插件如下：

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>1.4.1.RELEASE</version>
    <executions>
      <execution>
        <goals>
          <goal>repackage</goal>
        </goals>
        <configuration>
          <classifier>exec</classifier>
        </configuration>
      </execution>
    </executions>
    ...
  </plugin>

或者你也可以声明主类。

<plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>YourMainClass.java</mainClass>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
