带有 Maven Shade 插件的 Spring Boot - 控制器未映射(404 错误) [英] Spring Boot With Maven Shade Plugin - Controllers not mapped (404 Error)
问题描述
对于我的带有嵌入式 tomcat 的 Spring Boot 应用程序，由于某些限制，我需要取消 spring-boot-maven-plugin 并需要使用 maven-shade-plugin.使用 maven package 命令我可以成功创建 jar 文件.但是，我所有的控制器都停止工作并给我 404 错误.放置在我的资源文件夹中的静态内容也不再提供.总是收到 404 错误.
For my Spring boot application with embedded tomcat, due to some limitation I need to do away with spring-boot-maven-plugin and need to use maven-shade-plugin. With maven package command I could successfully create the jar file. However, all my controllers stopped working and gives me 404 error. Also static content placed in my resources folder are not being served anymore. Always getting 404 error.
我的 pom.xml

我像往常一样运行应用程序:
I run the application as usual:
@SpringBootApplication
public class MyMainClass{
public static void main(String[] args) {
SpringApplication.run(MyMainClass.class, args);
}
}
我还必须创建以下 EmbeddedServletContainerFactory bean，否则会抛出错误.
Also I had to create following EmbeddedServletContainerFactory bean, otherwise an error will be thrown.
@Bean
public EmbeddedServletContainerFactory servletContainer() {
TomcatEmbeddedServletContainerFactory tomcat = new TomcatEmbeddedServletContainerFactory();
return tomcat;
}
最后，我只有一个示例控制器，
Finally, I just have a one sample controller,
@RequestMapping(value = "/car", method = RequestMethod.GET)
@ResponseBody
public Car test() {
return new Car();
}
当我使用 spring-boot-maven 插件时，同样的代码可以正常工作.在我开始使用 maven-shade-plugin 后不久，tomcat 就成功启动了.但是，所有控制器都给我 404 错误.如果我做错了什么，请指导我.
This same code works without any issue when I use spring-boot-maven plugin. Soon after I started using maven-shade-plugin, tomcat boots up successfully. however, all controllers gives me 404 error. Please guide me if I'm doing anything wrong.
推荐答案
如果你想从 spring-boot-maven 插件迁移到 maven-shade 插件，这很简单.我已将以下插件信息添加到 pom.xml 并解决了问题.
It is very simple if you want to migrate from spring-boot-maven plugin to maven-shade plugin. I've added following plugin information to pom.xml and problem resolved.
