java - Spring MongoDB 和 Apache Shiro

Question

我正在尝试将 Apache Shiro 与 Spring 和 MongoDB 结合使用。我正在使用 Autowiring 的 Spring Data Repositories。我为 Shiro 创建了自己的自定义领域，它使用 Spring Data 存储库与 Mongo 对话:

public class PlatformRealm extends AuthorizingRealm {

    @Autowired(required = true)
    protected UserRepository userRepository = null;

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken token) throws AuthenticationException {
         ...
    }
}

我看到的问题是 userRepository 没有被 Autowiring 。我在我的控制台输出中得到了以下引用 PlatformRealm 的行:

INFO  org.springframework.web.context.support.XmlWebApplicationContext  - Bean 'platformRealm' of type [class com.resonance.platform.core.security.PlatformRealm] is not eligible for getting processed by all BeanPostProcessors (for example: not eligible for auto-proxying)

这是因为 Apache Shiro ShiroFilterFactoryBean。正在发生的是这个 bean 及其所有依赖项在容器启动时立即加载。它不会在解析依赖关系之前等待我的持久性 bean 被初始化。这会导致存储库引用为空。

以下 bean 配置通过 contextConfigLocation 参数加载:

<context-param> 
    <param-name>contextConfigLocation</param-name> 
    <param-value>
        /WEB-INF/web-platform-persistence.xml,
        /WEB-INF/web-platform-services.xml
    </param-value> 
</context-param> 

服务 bean 配置:

持久化 bean 配置:

    </property>
</bean>

<mongo:repositories base-package="com.resonance.platform.core.data.repositories" />

用户存储库:

package com.resonance.platform.core.data.repositories;

import org.bson.types.ObjectId;
import org.springframework.data.repository.CrudRepository;

import com.resonance.platform.core.entities.User;

/**
 * A repository used to manage User entities.
 * @author Kyle
 */
public interface UserRepository extends CrudRepository<User, ObjectId> {

    /**
     * Gets a user by the specified login.
     * @param login
     * @return
     */
    User getByLogin(String login);

}

我的问题是，如何正确解析 userRepository 依赖项？我知道 ShiroFilterFactoryBean 必须在其他依赖项和诸如此类的东西之前初始化，但必须有一种方法来解决 userRepository 依赖项。

编辑:添加了用户存储库代码。

我遇到了此处描述的相同问题。我注意到两个 Spring 工厂。

1. 从加载@Service @Repository 类的 dispacher-servlet.xml 中，由于在基础包级别定义的组件扫描，所以我可以将 @Autowire 服务类放入 Controller 。
2. 来自应用程序上下文的@Autowire 类似乎没有被标记为@Service，因为它们没有被加载。
