Spring Security无法访问服务层中的自定义userDetailsService Bean

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userDetailsServiceImpl，而是无法实例化的addUserFormController，因为它无法自动连接userDetailsServiceImpl。因此，问题来自这样一个事实：无论出于何种原因，该控制器都无法访问该服务bean UserDetailsServiceImpl。我想我已经正确地进行了组件扫描，只扫描了mvc-dispatcher-servlet.xml中的控制器，以及applicationContext中除控制器之外的所有其他控制器。

我正在使用SpringMVC和Hibernate，并试图将SpringSecurity与自定义UserDetailsService和汇编程序集成

看起来我的spring安全性无法访问applicationContext.xml应该扫描的bean

加载应用程序时，我遇到以下错误：

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.

    org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.populateBean(AbstractAutowireCapableBeanFactory.java:1106)

以下是我的spring-security.xml：

我的UserDetailsServiceImpl：

package com.service;
@Service("userDetailsService")
@Transactional
public class UserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private UserEntityDAO dao;

    @Autowired
    private Assembler assembler;

---

我已经解决了这个问题

在我的AddUserFormController中，我有：

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

public class AddUserFormController {

private UserDetailsService userDetailsService;


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

下面是它现在的样子：

@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userDetailsService的类型更改为userDetailsService，而不是UserDetailsServiceImpl。

您似乎在package com.service中声明了它，但在定义中包丢失了。@Jinzhao Wu-包没有丢失，我只是没有把它贴在我的帖子里。我编辑了我的第一篇文章来反映这一点。你确定

userDetailsService

是从spring容器实例化的吗？如果你看到异常，它将无法找到

userDetailsService

的实例。因此，在控制台中，当服务器启动时，您可以看到所有bean都创建了什么。@Jinzhao Wu-是的，包声明在AddUserFormController:package com.controller中；是这样吗？

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

public class AddUserFormController {

    private UserDetailsServiceImpl userDetailsService;

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

package com.service;
@Service("userDetailsService")
@Transactional
public class UserDetailsServiceImpl implements UserDetailsService {

    @Autowired
    private UserEntityDAO dao;

    @Autowired
    private Assembler assembler;

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

public class AddUserFormController {

private UserDetailsService userDetailsService;


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

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

    @Autowired
    private UserDetailsService userDetailsService;

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