15.6. JAX-RS Web Service Security
15.6.1. 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
Changing the default values of the following RESTEasy parameters may cause RESTEasy applications to be potentially vulnerable against XXE attacks.
- resteasy.document.expand.entity.references
- resteasy.document.secure.processing.feature
- resteasy.document.secure.disableDTDs
For more information about these parameters, see Section 15.5.1, “RESTEasy Configuration Parameters”.
Warning
Do not activate role-based security if the application uses EJBs. The EJB container will provide the functionality, instead of RESTEasy.
Procedure 15.1. Enable Role-Based Security for a RESTEasy JAX-RS Web Service
- Open the
web.xmlfile for the application in a text editor. - Add the following <context-param> to the file, within the
web-apptags:<context-param> <param-name>resteasy.role.based.security</param-name> <param-value>true</param-value> </context-param> - 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> - 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.
Example 15.1. Example Role-Based Security Configuration
<web-app>
<context-param>
<param-name>resteasy.role.based.security</param-name>
<param-value>true</param-value>

<url-pattern>/*</url-pattern>
</servlet-mapping>
<security-constraint>
<web-resource-collection>
<web-resource-name>Resteasy</web-resource-name>
<url-pattern>/security</url-pattern>
</web-resource-collection>
<auth-constraint>
<role-name>admin</role-name>
<role-name>user</role-name>
</auth-constraint>
</security-constraint>
<security-role>

15.6.2. Secure a JAX-RS Web Service using Annotations
Summary
This topic covers the steps to secure a JAX-RS web service using the supported security annotations
Procedure 15.2. Secure a JAX-RS Web Service using Supported Security Annotations
- Enable role-based security. For more information, refer to: Section 15.6.1, “Enable Role-Based Security for a RESTEasy JAX-RS Web Service”
- Add security annotations to the JAX-RS web service. RESTEasy supports the following annotations:
- @RolesAllowed
- Defines which roles can access the method. All roles should be defined in the
web.xmlfile. - @PermitAll
- Allows all roles defined in the
web.xmlfile to access the method. - @DenyAll
- Denies all access to the method.
