How do I specify local file path to my ssl keystore file in spring application.properties?

Question

Given I have file in c:\\path\\to\\file\\keystore.jks

and my application.properties file contains server.ssl.key-store=c:\\path\\to\\file\\keystore.jks

I get the following exception java.io.FileNotFoundException: C:\\Windows\\Temp\\tomcat.2910824355292831382\\file:\\c:\\path\\to\\file\\keystore.jks (The filename, directory name, or volume label syntax is incorrect)

What is the correct way to specify the path?

Answer 1

Do not rely on absolute paths. Put the file into same directory as Spring Boot JAR and add this line into your application.properties:

server.ssl.key-store=file:keystore.jks

Second option is to pass system variable to -Dserver.ssl.key-store=file:keystore.jks

Answer 2

Below worked for me with Tomcat 8.5.2:

Windows:

server:
  ssl:
    key-store: file:C:\<complete file path with extension>

Linux:

server:
  ssl:
    key-store: file:/J2EE/<complete file path with extension>

Answer 3

This worked for me when I made these changes:

1. Set tomcat's version to 8.5.20
2. Changed the property to : file:path

Answer 4

Check which version of tomcat is being used by spring boot. According to this github issue tomcat versions less than 7.0.66 relativize the server.ssl.key-store setting.

Answer 5

Putting file: didn't work for relative paths for me. In summary:

If you put the keystore in your resources, you do this:

key-store: classpath:keystore.jks

However, if you try this:

key-store: file:keystore.jks

you will get:

java.lang.IllegalStateException: no valid keystore

So, instead, just do this:

key-store: keystore.jks

Strangely, if you supply the full path (not relative path), then file: will still work.

Answer 6

Just use quotes for keystore file path

server:
  port: 8443
  ssl:
    enabled: true
    key-store: "/path/to/keystore/keystore.jks"
