Spring MongoDB和Apache Shiro [英] Spring MongoDB and Apache Shiro
问题描述
我正在尝试将Apache Shiro与Spring和MongoDB一起使用。我正在使用自动装配的Spring Data Repositories。我为Shiro创建了自己的自定义域，它使用Spring Data存储库与Mongo交谈：
I am attempting to use Apache Shiro with Spring and MongoDB. I am using Spring Data Repositories which are autowired. I have created my own custom realm for Shiro which uses a Spring Data repository to talk to Mongo:
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没有自动装配。我在控制台输出中得到以下一行，引用PlatformRealm：
The problem I'm seeing is the userRepository isn't being autowired. I get the following line in my console output referring to the PlatformRealm:
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。发生了什么事情是这个bean及其所有依赖项在容器启动时立即被加载。在解析依赖项之前，它不会等待我的持久性bean被初始化。这会导致存储库引用为null。
This is because of the Apache Shiro ShiroFilterFactoryBean. What is happening is this bean and all of its dependencies are being loaded up immediately when the container is started. It doesn't wait for my persistence beans to be initialized prior to resolving dependencies. This causes the repository reference to be null.
通过contextConfigLocation参数加载以下bean配置：
The following bean configurations are loaded via the contextConfigLocation parameter:
<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>

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，我怎样才能获得userRepository依赖关系解决得好吗？我知道ShiroFilterFactoryBean必须在其他依赖项和诸如此类之前初始化，但必须有一种方法来解析userRepository依赖项。
My question is, how can I get the userRepository dependency to resolved properly? I understand that the ShiroFilterFactoryBean has to be initialized before the other dependencies and whatnot, but there must be a way to get the userRepository dependency to be resolved.
编辑：添加用户存储库代码。
Added User Repository code.
推荐答案
我遇到了同样的问题。
我注意到两个弹簧工厂。
I am running into the same problem described here. I am noticing two spring factories.
- 来自dispacher-servlet.xml，由于组件而加载@Service @Repository类-scan在基本包级别定义，因此我可以@Autowire Service类进入Controller。
- 来自应用程序上下文似乎@Autowire类标记为@Service，因为它们未加载。
