Spring MVC - 将spring-security导入pom.xml会导致@Autowired问题

标签： spring spring-mvc spring-security autowired proxy-classes

首先，这是我的帖子，我想谦虚地向SO社区打招呼 - 我已经找到了很多针对各种问题的答案，并在这里解决了一大堆问题。

但我偶然发现了一个问题，我无法找到解决办法。我想在这里指出这个事实，我已经开发了一个月，所以我在春季初级。

我正在开发一个后端RESTful Web服务，它处理和处理来自专用Android和iOS应用程序的请求。我在服务器端使用Spring MVC模板（版本4.1.4.RELEASE），使用Wildfly 8.2作为容器。

现在，我必须实现哈希算法来编码用户激活密码和唯一设备标识符（当前这些值以原始明文存储在数据库中），并将输入与散列值匹配。

Spring Security提供了一个方便的BCrypt密码编码器/匹配器类，完全满足我的需求（我不需要其他Spring Security功能，如过滤器链接等，但我最终会使用它们，当我熟悉Spring并掌握时安全概念）。

将Spring-Security实现到我的项目的第一步已经是showstopper - 导入spring-security-config和/或spring-security-core pom.xml依赖项并尝试部署我的应用程序，导致在上下文中出现代理错误在我的服务类中初始化：

这是导致问题的pom.xml依赖（版本为3.2.6.RELEASE）

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-config</artifactId>
    <version>${org.springframework.security-version}</version>
</dependency>

当我注释掉spring-security依赖项时，autowiring正确执行，我的app成功部署。

我的项目结构似乎没问题，这可以通过有效的初始化证明，当不导入Spring-Security依赖项时：

pl.atwork.dao
---EmployeeDao.java
...
pl.atwork.model
---Employee.java
...
pl.atwork.service
---AuthenticationService.java
...
pl.atwork.service.controller
---RestController.java

RestController类，Autowires服务：

    @Controller
    public class RestController {

        @Autowired
        private AuthenticationService authService;

... other Autowired services fields and controller methods

AuthenticationService类，其中代理错误从第一个@Autowired注释开始：

    @Service
    public class AuthenticationService implements Serializable {

        @Autowired
        private EmployeeDao empDao;

... other Autowired fields and @Transactional methods

EmployeeDao类，在自动装配时无法解决：

@Repository
public class EmployeeDao implements Serializable {

    @Autowired
    private SessionFactory sessionFactory;

    ... typical DAO methods

我尝试在上下文文件中强制执行GGLib代理，但它对我不起作用。我还尝试按类型使用@Qualifier并为我的@Autowired字段命名注释，但它也不起作用。

似乎导入spring-security依赖项完全弄乱了我的@Autowired配置，此时我已经没有想法了。我的最新线索是，我的组件扫描上下文文件可能有点尴尬，但我不知道如何让它看起来更好看。此外，我不太确定我是否应该在我的项目中使用接口，并自动装配它们而不是具体实现。我没有找到在我的项目中使用接口的充分理由，因为它不太宽泛的范围是不值得的。

任何帮助都会非常感激 - 我现在已经坚持了几天。

2 个答案:

答案 0 :(得分：0)

尝试使用限定符：

@Repository("employeeDao")
public class EmployeeDao implements Serializable {

然后

    @Autowired
    @Qualifier("employeeDao")
    private EmployeeDao empDao;

答案 1 :(得分：0)

问题解决了！我经历了每一个pom.xml导入，发现它很奇怪，我没有将spring-aop依赖项添加到我的项目中。我认为AspectJ或其他Spring核心依赖项都很简单，但事实证明Spring Security没有解析没有Spring-AOP依赖的代理bean。

如果您能提供全面的解释，我将很高兴知道为什么会这样。
