在专用的tomcat上将spring-boot应用程序作为war文件部署不起作用

本文介绍了在专用的tomcat上将spring-boot应用程序作为war文件部署不起作用的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个spring-boot应用程序，现在我想在专用的tomcat服务器上部署该应用程序，而不要使用嵌入式tomcat.两种部署方式都没有任何错误.

我已为 spring-boot-starter-tomcat 依赖项提供了 scope = provided .

当我运行带有嵌入式tomcat的应用程序(进行了适当的更改)时，它在点击链接http://localhost:8080/testGET时运行良好.但是，当我在 scope = provided 上运行专用的tomcat时，点击链接http://localhost:8080/test-results-upload-1.0/testGET或http://localhost:8080/testGET时，我得到的响应已映射到/error ./p>

请帮助我.无法理解我正在做的错误.

谢谢.

解决方案

自从首次提出此问题以来已经有一段时间了，分享了我为将Spring boot application打包为war打包部署在Tomcat服务器上所做的工作(External)，使用Maven:

  1. 可部署Servlet 3.0 API容器的war文件(意味着它可以在Tomcat 7.0.x及更高版本上正确部署)
    • 环境设置:
      • 需要安装Tomcat 7.0.x版本，因为可以从 Tomcat 7.0获得对Servlet 3.0 API的支持. x 起.
      • Java 1.8(确保在相同的Java版本上进行构建(JDK8)并运行(JRE8 Tomcat JVM目标)).
        • 注意:Java 1.7也可以，只需确保编译并在相同版本上运行即可.
    • 代码:
      • 引导应用程序类更改:请遵循扩展SpringBootServletInitializer
      • Maven构建文件pom.xml更改:
        • 将<artifactId>spring-boot-starter-tomcat</artifactId>的范围更改为<scope>provided</scope>
        • 最后，我们需要将其捆绑为war文件，以便更改包装<packaging>war</packaging>

I have a spring-boot application and now that I want to deploy the application on a dedicated tomcat server and not using the embedded tomcat. Both ways on deploying I'm not getting any error.

I have given the scope=provided for the spring-boot-starter-tomcat dependency.

When I run the application with embedded tomcat (with appropriate changes made), its working perfectly on hitting the link http://localhost:8080/testGET.But when I ran on the dedicated tomcat with scope=provided, on hitting the link http://localhost:8080/test-results-upload-1.0/testGET or http://localhost:8080/testGET I'm getting the response mapped to /error.

Please help me with this. Not able to understand mistake I'm doing..

Thanks in advance.

解决方案

It has been a while since this question was first asked, sharing what I did to get a Spring boot application packaged as war deployed on Tomcat server (External), using Maven:

  1. Deployable war file for Servlet 3.0 API Container (meaning it can be deployed correctly on Tomcat 7.0.x onwards)
    • Environment Setup :
      • Need to have Tomcat 7.0.x version installed, as Support for Servlet 3.0 API is available from Tomcat 7.0.x onwards.
      • Java 1.8 (Make sure to build (JDK8) and run(JRE8 Tomcat JVM target) on the same Java versions).
        • Note:Java 1.7 would also do, just make sure to compile and run on same versions.
    • Code:
      • Boot Application class changes: follow the instructions of extending SpringBootServletInitializer
      • Maven build file pom.xml changes:
        • Change of scope for <artifactId>spring-boot-starter-tomcat</artifactId> to <scope>provided</scope>
        • Finally we need to bundle it as an war file so change of packaging <packaging>war</packaging>

这篇关于在专用的tomcat上将spring-boot应用程序作为war文件部署不起作用的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
