How do i check my object permissions in spring security acl instead of using hasPermission annotation

问题

Is there a way to check my class object permissions directly from my code instead of having the annotation model,

@PostAuthorize("hasPermission(returnObject, 'WRITE')")
public BaseData getSingle(Long id);

回答1:

Assuming you're intending to use the ACL module, the expression is implemented in AclPermissionEvaluator. So you can wire up an instance of that with an AclService, inject it into the classes that need it and call the hasPermission method directly.

At-last after several tries i could achieve to get the solution, following is the code

acl-conf.xml

...
<bean class="org.springframework.security.acls.AclPermissionEvaluator" id="permissionEvaluator">
        <constructor-arg ref="aclService"/>
</bean>
...

samplecontroller.java

 @Autowired
    private PermissionEvaluator permissionEvaluator ;

    Permission permission = BasePermission.WRITE;
   permissionEvaluator.hasPermission(authentication,aclObject,permission);
....

Hope this is helpful.
