Spring Security無法在服務層訪問自定義的userDetailsService Bean

編輯：我剛剛意識到問題並不是來自spring-security無法實例化在spring-security.xml文件中引用的userDetailsServiceImpl，而是addUserFormController無法實例化，因爲它無法自動調用UserDetailsServiceImpl。所以這個問題來自於這個控制器無論何種原因都無法到達這個服務bean的UserDetailsServiceImpl。我想我只是通過掃描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來掃描組件掃描。Spring Security無法在服務層訪問自定義的userDetailsService Bean

我正在使用Spring MVC和Hibernate，我試圖將Spring Security與自定義UserDetailsService和彙編程序集成。

看起來我的spring security無法訪問應該由applicationContext.xml掃描的bean。

當加載我的申請，我遇到了以下錯誤：

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.

我AddUserFormController：

public class AddUserFormController { 

    private UserDetailsServiceImpl userDetailsService; 

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

我UserDetailsServiceImpl：

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

    @Autowired 
    private UserEntityDAO dao; 

    @Autowired 
    private Assembler assembler;

看來你聲明它是在包com.service中，但是在包的缺失定義中。 – coderLMN

@Jinzhao Wu - 這個包沒有丟失，我只是沒有粘貼在我的帖子中。我編輯了我的初始文章以反映這一點。 – dukable

你確定'userDetailsService'是從spring容器中立即執行嗎？如果你看到你的異常它不能找到'userDetailsService'的實例。所以，在服務器啓動的時候在控制檯中看到，你可以看到所有的bean都被創建了。 – SRy

我已經能夠解決這個問題。

在我AddUserFormController，我有這樣的：

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

public class AddUserFormController { 

private UserDetailsService userDetailsService; 


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

這裏怎麼現在看起來是：

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

    @Autowired 
    private UserDetailsService userDetailsService; 

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

我感動的@Autowired從模子直接的屬性，最重要的是，我將userDetailsService的類型更改爲UserDetailsService，而不是UserDetailsServiceImpl。
