12.4. JAX-RS Application Security

12.4.1. Enable Role-Based Security for a RESTEasy JAX-RS Web Service

Summary

RESTEasy supports the @RolesAllowed, @PermitAll, and @DenyAll annotations on JAX-RS methods. However, it does not recognize these annotations by default. Follow these steps to configure the web.xml file and enable role-based security.

Warning

Do not activate role-based security if the application uses EJBs. The EJB container will provide the functionality, instead of RESTEasy.

Procedure 12.3. Enable Role-Based Security for a RESTEasy JAX-RS Web Service

  1. Open the web.xml file for the application in a text editor.
  2. Add the following <context-param> to the file, within the web-app tags:
    <context-param>
        <param-name>resteasy.role.based.security</param-name>
        <param-value>true</param-value>
    </context-param>
    
  3. Declare all roles used within the RESTEasy JAX-RS WAR file, using the <security-role> tags:
    <security-role>
        <role-name>ROLE_NAME</role-name>
    </security-role>
    <security-role>
        <role-name>ROLE_NAME</role-name>
    </security-role>
  4. Authorize access to all URLs handled by the JAX-RS runtime for all roles:
    <security-constraint>
        <web-resource-collection>
    	<web-resource-name>Resteasy</web-resource-name>
    	<url-pattern>/PATH</url-pattern>
        </web-resource-collection>
        <auth-constraint>
    	<role-name>ROLE_NAME</role-name>
    	<role-name>ROLE_NAME</role-name>
        </auth-constraint>
    </security-constraint>
Result

Role-based security has been enabled within the application, with a set of defined roles.
