Spring “configprops” endpoint can not show ConfigurationProperties options without a getter method

Question

I'm following this answer to add timeout mechanism for resttemplate.

To check whether my config is correct, I go through the output of configprops endpoint, the config options about timeout (e.g. connection-request-timeout, connect-timeout, read-timeout) can not be shown in it.

Answer 1

The config options without getter method can not be shown in the return of configprops endpoint.

In my case, connection-request-timeout, connect-timeout, read-timeout only have setter methods, so they can be config properly; but they don't have getter methods, it causes they can not be shown in configprops
