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

Question

我需要帮助。我有2个spring-boot-jar项目maven基，我想把第一个导入第二个，如图所示

我在Config Spring-Boot中导入Util Jar并运行Spring Boot，但它是Show error

<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：Compilation failure：

Answer 1

对于这个要求，您必须使用重新打包。

默认情况下，重新打包目标将用重新打包的工件替换原始工件。对于代表应用程序的模块来说，这是一种明智的行为，但是如果您的模块被用作另一个模块的依赖项，您需要为重新打包的模块提供一个分类器。

原因是应用程序类打包在boot-inf/classes中，因此依赖模块无法加载重新打包的JAR类。如果是这种情况，或者您希望保留原始工件，并用不同的分类器附加重新打包的工件，请按照以下方式配置插件：

<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>

也可以声明main class。

<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>
