我使用Heroku在PostgreSQL数据库中部署Spring MVC Java应用程序。链接到数据库工作良好,并且PostgreSQL已成功初始化。
部署成功,没有错误或看起来奇怪的警告消息,但是现在应用程序失败了。
以下是日志:
heroku[web.1]: State changed from crashed to starting
heroku[web.1]: Starting process with command `java $JAVA_OPTS -Dspring.profiles.active="datajpa,heroku" -DMISIC_ROOT="." -jar target/dependency/webapp-runner.jar --port 28363 target/*.war`
heroku[web.1]: State changed from starting to crashed
heroku[web.1]: Process exited with status 1
app[web.1]: Setting JAVA_TOOL_OPTIONS defaults based on dyno size. Custom settings will override them.
app[web.1]: Error: Unable to access jarfile target/dependency/webapp-runner.jar
heroku[router]: at=error code=H10 desc="App crashed" method=GET path="/" host=misic.herokuapp.com request_id=a242ee89-5594-4f48-9d14-432d46b17600 fwd="178.21.66.110" dyno= connect= service= status=503 bytes= protocol=https
我在stackoverflow上找不到任何答案,可以解决我的问题。 为什么Heroku找不到webapp-runner.jar,我不知道! 在localhost上,一切正常。
我的pom.xml(部分)

我解决了这个问题。由于某种原因,Heroku不使用文件setsings.xml。当我将该文件的内容传输到pom.xml并将其删除时,一切正常。

请确保您的pom.xml
中有类似的内容:

对我来说1)在尝试设置通过git而不是通过jarfile部署的jhipster upp时,我已经遇到了问题。我之所以拥有它,是因为Node.js buildpack是在Java的buildpack之前启动的,所以我被迫用heroku:buildpacks add --index 2 heroku/nodejs
来设置它们,并且heroku:buildpacks添加--index 1 heroku / java`,但是即使更改了我仍然有同样的错误。 2)然后我意识到我在pom,xml中有jar包装,而不是必需的war包装。将此值更改为pom.xml对我有所帮助。
