Spring Boot Web 应用程序无法在 Tomcat 上运行 - 404 错误 [英] Spring boot web app not working on Tomcat - 404 error
问题描述
注意:有与此类似的问题,但没有一个解决方案适合我.我花了几天时间试图让它发挥作用.
Note: There are similar questions to this one but none of the solutions work for me. I've spent a few days trying to get this to work.
我已将 WAR 文件部署到 Tomcat,Tomcat Web 应用程序管理器"显示它已启动.当我单击网络应用程序/forecaster"时,出现 404 错误.Web 应用程序在从调试器 (IntelliJ) 运行时工作.WAR 文件名为forecaster.war",我尝试过的路径是:http://localhost:8080/forecaster/http://localhost:8080/forecaster/forecast/http://localhost:8080/forecaster/forecast/1
I've deployed a WAR file to Tomcat and the "Tomcat Web Application Manager" shows that it has started. When I click on the web app "/forecaster" I get a 404 error. The web app works when running from the debugger (IntelliJ). The WAR file is named "forecaster.war" and the paths I've tried are: http://localhost:8080/forecaster/ http://localhost:8080/forecaster/forecast/ http://localhost:8080/forecaster/forecast/1

推荐答案
我最终按照此处的说明操作,而不是使用 IntelliJ.
I ended up following the instructions here instead of using IntelliJ.
https://spring.io/guides/gs/spring-boot/#_run_the_application
在本地运行应用程序:
./gradlew build && java -jar build/libs/forecaster/forecaster-0.0.3-SNAPSHOT.jar
为了构建我添加到 build.gradle 文件中的战争:
To build the war I added to the build.gradle file:
war {
baseName = 'forecaster'
version = '0.0.3-SNAPSHOT'
}
然后我跑了:
./gradlew build
这里生成了 WAR 文件:
This produced the WAR file here:
build/libs/forecaster/forecaster-0.0.3-SNAPSHOT.jar
build/libs/forecaster/forecaster-0.0.3-SNAPSHOT.jar
然后我将其复制到外部 Tomcat8 服务器(其中/external-test/是安装到/Library/Tomcat/webapps 的已安装 samba 文件夹):
And I copied that to the external Tomcat8 server (where /external-test/ is the mounted samba folder mounted to /Library/Tomcat/webapps):
cp build/libs/forecaster/forecaster-0.0.3-SNAPSHOT.war /external-test/forecaster.war
现在它适用于这个 URL:
Now it works with this URL:
http://localhost:8080/forecaster/forecast/1
