wso2-mi-jwt-validator

The wso2-mi-jwt-validator is a custom handler and mediator for the WSO2 Micro Integrator. This class can be used to validate JWT tokens against a JWKS endpoint. The class can be used as a custom handler or as a custom mediator. The following example shows how to use the class as a custom handler and mediator.

The wso2-mi-jwt-validator is available on the Maven Central Repository. You can find the latest version here.

Setup

With pom.xml

Add the following dependencies to your pom.xml file:

<dependency>
  <groupId>io.integon.wso2mi.jwt</groupId>
  <artifactId>wso2-mi-jwt-validator</artifactId>
  <version>1.2.1</version>
</dependency>
<dependency>
    <groupId>com.nimbusds</groupId>
    <artifactId>nimbus-jose-jwt</artifactId>
    <version>9.37.3</version>
</dependency>

These dependencies are required for the wso2-mi-jwt-validator to work. The wso2-mi-jwt-validator uses the nimbus-jose-jwt library to validate the JWT token.

Without pom.xml

Add the following .jar Files to the MI Folder "/home/wso2carbon/wso2mi-{version}/lib"

wso2-mi-jwt-validator-1.2.1.jar (or the latest version)
nimbus-jose-jwt-9.37.3.jar (or the latest version)

Both .jar files are available on the Maven Central Repository. You can find the latest version here and here.

Enable Debug Logs

In order to debug the JWT Mediator and Handler the following snippets need to be added to the "../mi-home/conf/log4j2.properties" file:

logger.JwtAuthMediator.name = io.integon.JwtAuthMediator
logger.JwtAuthMediator.level = DEBUG

logger.JwtAuthHandler.name = io.integon.JwtAuthHandler
logger.JwtAuthHandler.level = DEBUG

Furthermore, the "JwtAuthMediator" and "JwtAuthHandler" need to be added to the list of loggers:

loggers = ..., ..., ..., JwtAuthMediator, JwtAuthHandler
