Hide

In Windows,I use spring.servlet.multipart.location=/opt/jar-application-dir
And then io.undertow.servlet.core.ManagedServlet Line 75 , will return false.then in line 78 will throw the NullPointException. The reason is field tempDir was null.

In Linux, I use spring.servlet.multipart.location=C://jar-application-dir
And then io.undertow.servlet.core.ManagedServlet Line 75 , will return false.then in line 78 will throw the NullPointException. The reason is field tempDir was null.

Seem like the Method Path.isAbsolute() can not recognize diffrent OS file system. and then UndertowServletWebServerFactory.createDeploymentManager() didn't init the field tempDir

I am using Spring Boot undertow construct upload file class, the configuration of the 'spring.servlet.multipart.location' attributes, when the attribute value and the current environment is not configured at the same time, the undertow ManagedServlet setupMultipart method to obtain the 'servletContext.getDeployment().getDeploymentInfo().getTempPath()' returns value. But this method doesn't seem to return the correct value.

This is exception stacktrace :
