我正在尝试在 Heroku 上设置我的 Spring Boot + React JS 应用程序。但是，每当我尝试部署它时，构建都会成功，但是当我检查日志时应用程序崩溃了。
我尝试将代理更改为 Heroku 应用程序 Web 链接，但这似乎不起作用。
这是我的package.json:
{
"name": "frontend",
"version": "0.1.0",
"private": true,
"engines": {
"node": "12.10.0",
"npm": "6.10.3"
},
"dependencies": {
"react": "^16.10.0",
"react-dom": "^16.10.0",
"react-scripts": "3.1.2",
"yarn": "^1.17.3"
},
"scripts": {
"start": "react-scripts start",
"build": "react-scripts build",
"test": "react-scripts test",
"eject": "react-scripts eject",
"move-build": "mkdir -p ../main/resources/static && mv build/* ../main/resources/static/",
"clean-old-build": "rm -rf ../main/resources/static/* ",
"clean-new-build": "rm -rf build"
},
"proxy": "http://yumdrop.herokuapp.com",
"eslintConfig": {
"extends": "react-app"
},
"browserslist": {
"production": [
">0.2%",
"not dead",
"not op_mini all"
],
"development": [
"last 1 chrome version",
"last 1 firefox version",
"last 1 safari version"
]
}
}
这是Procfile:
web: java -D server.port=$PORT $JAVA_OPTS -jar target/yumdrop-0.0.1-SNAPSHOT.jar
application.properties 文件:
spring.mvc.view.suffix = .html
server.port=${PORT:8080}

最佳答案
-D server.port=$PORT 应为 -Dserver.port=$PORT
