Spring boot 带Maven Shade插件的Spring引导-控制器未映射（404错误）

对于使用嵌入式tomcat的Spring boot应用程序，由于某些限制，我需要取消

Spring boot maven插件

，并需要使用

maven shade插件

。使用maven package命令，我可以成功地创建jar文件。然而，我所有的控制器都停止工作，并给我404错误。此外，不再提供放置在“我的资源”文件夹中的静态内容。总是得到404错误

我还必须创建以下EmbeddedServletContainerFactorybean，否则将抛出一个错误

@Bean
public EmbeddedServletContainerFactory servletContainer() {
    TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory();
    return tomcat;
}

最后，我只有一个示例控制器

@RequestMapping(value = "/car", method = RequestMethod.GET)
@ResponseBody
public Car test() {
    return new Car();
}

---

当我使用SpringBootMaven插件时，同样的代码可以正常工作。在我开始使用maven shade插件后不久，tomcat就成功启动了。然而，所有控制器都给我404错误。如果我做错了什么，请指导我。

除了现有的外，尝试使用附加变压器，例如：

<transformer
                                implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass>abc.MyMainClass</mainClass>
                            </transformer>
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                 <resource>META-INF/spring.handlers</resource>
                                </transformer>
                                <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                                         <resource>META-INF/spring.schemas</resource>
                                </transformer>
                                <transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                 <resource>META-INF/spring.tooling</resource>
                                </transformer>

abc.mymain类
META-INF/spring.handlers
META-INF/spring.schemas
META-INF/spring.com

参考文档：

如果您想从spring boot maven插件迁移到maven shade插件，这非常简单。我已经在pom.xml中添加了以下插件信息，并解决了问题

感谢您的快速回复。。我试过了，但没用。似乎我从SpringBootMaven插件迁移到maven shade插件的方式是错误的。需要弄清楚如何正确地配置它。如果有人能提供一个使用maven shade插件的Spring Boot的工作示例，那将非常有用。谢谢
