Keycloak admin REST API - search user by username

[Tomáš Hariň]

Hi,

Im using org.keycloak.keycloak-spring-boot-2-starter library and Keycloak server version 11.02.

My build.gradle looks like this:

compile("org.keycloak:keycloak-spring-boot-2-starter:4.0.0.Final")

implementation group: 'org.keycloak', name: 'keycloak-admin-client', version: '12.0.4'

And my problem is, that I can't search users with special chars in email (ie.: use...@gmail.com). I must encode char '+', but char '@' not. And I don't know, which encoding have to use. All encoders encode char '@' too, and this is problem. Keycloak give me feedback, that user doesn't exist. However, when I use create user API. I get response for conflict, because user exists. So, can you help me, if I can use some library in java for encode email query param? Because I don't wanna write custome encoder, when I know, that only '@' char must bed decoded.

Thank you for your response, Harin Tomas.
