Using Spring Security ACL with Spring Data REST

问题:

I am trying to authorize apis exposed by Spring Data REST. So far I am able to do role-based authorization i.e:

@RepositoryRestResource(path = "book")
public interface BookRepository extends JpaRepository<Book, Long> {

    @PreAuthorize("hasRole('ROLE_ADMIN')")
    <S extends Book> Book save(Book book);
}

Also in the same project i have a service layer with ACL mechanism, which is working.

I am unable to use PostFilter expression with Spring Data REST i.e:

@PostFilter("hasPermission(filterObject, 'read') or hasPermission(filterObject, admin)")
List<Book> findAll();

It would be of great help, if anyone using ACL with Spring Data REST.

Note: I am aware of below open issues:

https://jira.spring.io/browse/DATAREST-236

https://jira.spring.io/browse/SEC-2409

回答1:

using JpaRepository was shadowing List<Book> findAll() method. Then I used CrudRepository, and PostFilter got applied.

For more details, a sample project is available on GitHub: https://github.com/charybr/spring-data-rest-acl

ACL-based authorization is working for below entity exposed by Spring Data REST.

import org.springframework.data.repository.CrudRepository;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;
import org.springframework.security.access.method.P;
import org.springframework.security.access.prepost.PostFilter;
import org.springframework.security.access.prepost.PreAuthorize;

@RepositoryRestResource(path = "book")
public interface BookRepository extends CrudRepository<Book, Long> {

    @PreAuthorize("hasRole('ROLE_ADMIN') or hasPermission(#book, 'write')")
    <S extends Book> Book save(@P("book") Book book);

    @Override
    @PostFilter("hasPermission(filterObject, 'read') or hasPermission(filterObject, admin)")
    Iterable<Book> findAll();
}
