Spring MVC控制器继承Spring安全性 [英] Spring MVC controller inheritance with spring security

问题描述

我正在尝试使用spring mvc 3.2.3和spring security 3.1.3创建一个通用控制器。
我想要实现的是这样的：

I'm trying to create a generic controller using spring mvc 3.2.3 and spring security 3.1.3. What i'm trying to achieve is something like this:

public abstract class DataController<E extends PersistentEntity> {
protected abstract E getEntity(String id);

@RequestMapping(value="/view/{id}", method=RequestMethod.GET)
public String view(@PathVariable("id") String id, ModelMap map) {
      E ent = getEntity(id);
      map.put("entity", entity);
      return "showEntity";
    }
}

我的扩展类将具有特定的控制器映射类名，以便我可以使用控制器名称访问该URL：

My extended class will have a specific controller mapping in the class name so that i can access the url by using the controller name:

@Controller
@RequestMapping("/company**")
@Secured("ROLE_ADMIN")
public class CompaniesController extends DataController<Company> {
    @Autowired
    private AppService appService;

    @Override
    protected Company getEntity(String id) {
        return appService.getCompany(id);
    }
}

我的问题是url / company / view是由ROLE_ADMIN保护并且任何人都可以访问，（我认为），因为/ view未在使用@Secured的控制器中定义。

My problem is that the url /company/view is not secured by ROLE_ADMIN and can be accessed by anyone, (i think) because the /view is not defined in the controller where the @Secured is being used.

这可以通过覆盖view方法并在我的公司类中定义映射来修复：

This can be fixed by just overriding the view method and define the mapping in my company class:

    . . .

    @Override
    @RequestMapping(value = "/view/{id}", method = RequestMethod.GET)
    public String view(String id, ModelMap map) {
        return super.view(id, map);
    }

    . . .

在这种情况下，安全性正常，但我想知道是否有其他方法。因为我的抽象类中有很多方法，所以这会产生一个问题，并且只是为了调用super来覆盖所有方法。

In this case the security works correctly, but i want to know if there is another method. Since i have a lot of methods in my abstract class, this will create a problem and a mess to override all methods just to call the super.

有没有办法解决这个问题？

Is there a way to fix this issue?

推荐答案

我知道这是一年之后，但我遇到了同样的问题，并为此找到了可能的解决方案。它不是基于100％注释，但有效并且有点优雅

I know it's a year later, but I had the same problem and figured out a possible solution for this. It is not 100% annotation based, but works and is somewhat elegant

抽象超类：

@PreAuthorize("hasAnyRole(this.roles)")
public abstract class DataController<E extends PersistentEntity> 
{
    protected abstract E getEntity(String id);

    protected abstract String[] getRoles();

    @RequestMapping(value="/view/{id}", method=RequestMethod.GET)
    public String view(@PathVariable("id") String id, ModelMap map) {
       E ent = getEntity(id);
       map.put("entity", entity);
       return "showEntity";
    }
 }

在子类上，您只需实现 getRoles（）返回访问此类所需的角色数组。

On the subclass you simply implement getRoles() to return an array of roles that are required to access this class.

@PreAuthorize 是另一种检查身份验证的方法，它允许您使用SpEL表达式。 this.roles 指的是带注释对象的 getRoles（）属性。

@PreAuthorize is another way to check authentication, that allows you to use SpEL expression. this.roles refers to he getRoles() property on the annotated object.
