春与Maven

Question

我想使用Spring和Maven的web服务，当我启动应用程序，我有这样的问题：

Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:exec 
(default-cli) on project WebService: Command execution failed. Process 
exited with an error: 1 (Exit value: 1) -> [Help 1]

你能帮助我吗？

Answer 1

您正在使用Spring Boot，并且正在努力不使用它，至少在您的pom.xml中。首先，您不需要javaee-web-api依赖项。初学者的想法是那些管理所有需要的依赖关系。所以简单地删除它。这同样适用于spring-boot-starter，因为spring-boot-starter-web依赖关系暗示了这一点。

您已经定义了许多额外的插件，Spring Boot已经拥有所需的配置，现在您正在使用一个非常旧的版本覆盖或更糟。删除所有的插件，只留下Spring Boot之一。

所以你基本上需要做的只是去掉你的pom.xml这应该给你带来像下面这样的东西。

专业提示：我会建议使用罐子而不是战争这样你可以简单地提供一个jar文件，然后执行java -jar WebService.jar和拥有一切启动和运行中没有时间。你不再需要这样的战争了。
