编辑：我刚刚意识到问题不是来自 spring-security 无法实例化 spring-security.xml 文件中引用的 userDetailsS​​erviceImpl，而是 addUserFormController 无法实例化，因为它无法自动装配 UserDetailsS​​erviceImpl。所以问题来自这样一个事实，无论出于何种原因，这个 Controller 都无法访问这个 Service bean UserDetailsS​​erviceImpl。我认为我确实正确地进行了组件扫描，仅扫描 mvc-dispatcher-servlet.xml 中的控制器，以及除 applicationContext 中的控制器之外的所有其他控制器。

我正在使用 Spring MVC 和 Hibernate，并且正在尝试将 Spring Security 与自定义 UserDetailsS​​ervice 和 Assembler 集成。

看起来我的 Spring Security 无法访问应该由 applicationContext.xml 扫描的 bean。

加载我的应用程序时，我遇到了以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'addUserFormController': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void com.controller.AddUserFormController.setUserDetailsService(com.service.UserDetailsServiceImpl); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [com.service.UserDetailsServiceImpl] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

public class UserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private UserEntityDAO dao;

    @Autowired
    private Assembler assembler;

我已经能够解决这个问题。

在我的 AddUserFormController 中，我有这个：

@Controller
@RequestMapping("/register.htm")

public class AddUserFormController {

private UserDetailsService userDetailsService;


    @Autowired
    public void setUserDetailsService(UserDetailsServiceImpl userDetailsService) {
        this.userDetailsService = userDetailsService;
    }

这是它现在的样子：

@Controller
@RequestMapping("/register.htm")
public class AddUserFormController {

    @Autowired
    private UserDetailsService userDetailsService;

    public void setUserDetailsService(UserDetailsServiceImpl userDetailsService) {
        this.userDetailsService = userDetailsService;
    }

我将 @Autowired 从 setter 直接移动到属性，最重要的是，我将 userDetailsS​​ervice 的类型更改为 UserDetailsS​​ervice，而不是 UserDetailsS​​erviceImpl。
