spring启动包不存在错误

Question

我编译我的项目与mvn清洁包，并失败与包不存在。

“详细信息”命令：

• 获取jar文件target/xxxx。jar通过在源项目中运行mvn clean package

这里是源代码项目pom.xml

Answer 1

理想情况下，您不应该使用Spring Boot应用程序（已重新打包的应用程序）作为依赖项。从文件中：

与war文件一样，Spring Boot应用程序不打算用作依赖项。如果应用程序包含要与其他项目共享的类，建议的方法是将该代码移动到单独的模块中。然后，您的应用程序和其他项目可以依赖单独的模块。

如果建议的解决方案在您的情况下不可行，文档将继续描述替代方案：

如果不能按照上述建议重新排列代码，则必须配置Spring Boot的Maven和Gradle插件，以生成适合作为依赖项使用的单独工件。可执行存档不能作为依赖项使用，因为可执行jar格式将应用程序类打包在BOOT-INF/类中。这意味着当可执行jar用作依赖项时，无法找到它们。

要产生两个工件，一个可以作为依赖项使用，另一个是可执行的，必须指定一个分类器。此分类器应用于可执行存档的名称，将默认存档用作依赖项。

要在Maven中配置exec分类器，可以使用以下配置：

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <classifier>exec</classifier>
            </configuration>
        </plugin>
    </plugins>
</build>
