Spring Security无法访问Service层中的自定义userDetailsS​​ervice 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userDetailsS​​erviceImpl，而是addUserFormController无法实例化，因为它无法实现自动装配UserDetailsS​​erviceImpl。所以问题来自于这个Controller无法以任何理由访问此Service Bean UserDetailsS​​erviceImpl的事实。我认为我只是通过扫描mvc-dispatcher-servlet.xml中的控制器以及applicationContext中除控制器之外的所有控制器来正确地进行组件扫描。

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

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

加载我的应用程序时遇到以下错误：

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.

我的AddUserFormController：

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

public class AddUserFormController {

    private UserDetailsServiceImpl userDetailsService;

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

我的UserDetailsS​​erviceImpl：

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

    @Autowired
    private UserEntityDAO dao;

    @Autowired
    private Assembler assembler;

1 个答案:

答案 0 :(得分：0)

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;
    }

以下是现在的样子：

@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。
