I am configuring a Mule application (running on API Gateway 2.1), and running into some issues when configuring spring security.
Here is the security config:
<spring:beans>
<ss:authentication-manager alias="authenticationManager">
<ss:authentication-provider >
<ss:user-service id="userService" properties="classpath:users.properties">
<!-- **** This works, but the properties file above ^ doesn't ****
<ss:user name="user" password="password" authorities="ROLE_ADMIN"/>
<ss:user name="anon" password="anon" authorities="ROLE_ANON" />
-->
</ss:user-service>
</ss:authentication-provider>
</ss:authentication-manager>
</spring:beans>
<mule-ss:security-manager name="security-manager"
doc:name="Spring Security Provider">
<mule-ss:delegate-security-provider
name="memory-provider" delegate-ref="authenticationManager" />
</mule-ss:security-manager>
users.properties is on my classpath and contains the following:
user=userpassword,ROLE_USER,enabled
admin=admin,ROLE_USER,ROLE_ADMIN,enabled
chris=chrispassword,ROLE_USER,enabled
What I find confusing is that when I use the embedded users (see commented section in Mule flow above), and remove the properties=classpath:users.properties, everything runs fine. But when I try to use users.properties, I get the exception below. I know that users.properties is being found on the classpath. Have I misconfigured users.properties? If this is a more general configuration problem why doesn't it always fail?
I'm getting the following exception (top part of the stack trace):
