Authorization control library
From Gcube Wiki
Authorization Control Library
allows gcube services to automatically filter methods using specific rules based on user roles
How To
pom file
To enable authorization control on your gcube service the pom.xml must be modified in the following way:
- add the authorization control library dependency
<dependency> <groupId>org.gcube.common</groupId> <artifactId>authorization-control-library</artifactId> </dependency>
- since this library use aspectJ also this dependency must be added
<dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.8.2</version> </dependency>
- the plugin must be declared in the plugins block
<plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>aspectj-maven-plugin</artifactId> </plugin> ...
- and execution added in the build block
<build> ... <pluginManagement> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>aspectj-maven-plugin</artifactId> <version>1.7</version> <configuration> <complianceLevel>1.8</complianceLevel> <source>1.8</source> <target>1.8</target> <aspectLibraries> <aspectLibrary> <groupId>org.gcube.common</groupId> <artifactId>authorization-control-library</artifactId> </aspectLibrary> </aspectLibraries> </configuration> <executions> <execution> <goals> <goal>compile</goal> </goals> </execution> </executions> </plugin> ...
Example
an example pom is the following
... <dependencies> <dependency> <groupId>org.gcube.common</groupId> <artifactId>authorization-control-library</artifactId> <version>[1.0.0-SNAPSHOT, 2.0.0-SNAPSHOT)</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.8.2</version> </dependency> ... </dependencies> <build> <finalName>${project.artifactId}</finalName> <pluginManagement> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>aspectj-maven-plugin</artifactId> <version>1.7</version> <configuration> <complianceLevel>1.8</complianceLevel> <source>1.8</source> <target>1.8</target> <aspectLibraries> <aspectLibrary> <groupId>org.gcube.common</groupId> <artifactId>authorization-control-library</artifactId> </aspectLibrary> </aspectLibraries> </configuration> <executions> <execution> <goals> <goal>compile</goal> </goals> </execution> </executions> </plugin> </plugins> </pluginManagement> <plugins> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>aspectj-maven-plugin</artifactId> </plugin> </plugins> </build>
Code
To put a method under authorization control is enough to annotate it with @AuthorizationControl
Example
@POST @Path("") @AuthorizationControl(allowedRoles={INFRASTRUCTURE_MANAGER_ROLE}, exception=MyAuthException.class) public void myServiceMethod(){ //TODO }
where MyAuthException
is
import javax.ws.rs.WebApplicationException; import javax.ws.rs.core.Response.Status; public class MyAuthException extends WebApplicationException { private static final long serialVersionUID = 1L; public MyAuthException(Throwable cause) { super(cause, Status.FORBIDDEN); } }
