SecurityConfig Java文件错误

我是Spring新手，尝试使用Spring为RESTful API创建身份验证。我遇到以下错误，如何解决此问题

堆栈跟踪：

Error creating bean with name 'webConfig': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter.setAuthenticationConfiguration(org.springframework.security.config.annotation.authentication.configuration.AuthenticationConfiguration); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.springframework.security.config.annotation.authentication.configuration.AuthenticationConfiguration] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {}

MySavedRequestAwareAuthenticationSuccessHandler.java

 @Component
public class MySavedRequestAwareAuthenticationSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {

    private RequestCache requestCache = new HttpSessionRequestCache();

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,
            Authentication authentication) throws ServletException, IOException {
        SavedRequest savedRequest = requestCache.getRequest(request, response);

        if (savedRequest == null) {
            clearAuthenticationAttributes(request);
            return;
        }
        String targetUrlParam = getTargetUrlParameter();
        if (isAlwaysUseDefaultTargetUrl()
                || (targetUrlParam != null && StringUtils.hasText(request.getParameter(targetUrlParam)))) {
            requestCache.removeRequest(request, response);
            clearAuthenticationAttributes(request);
            return;
        }

        clearAuthenticationAttributes(request);
    }

    public void setRequestCache(RequestCache requestCache) {
        this.requestCache = requestCache;
    }
}

使用

@EnableWebSecurity

进行web安全配置

将

WebConfig

从

WebSecurityConfig

拆分为不同的类

 @Component
public class MySavedRequestAwareAuthenticationSuccessHandler extends SimpleUrlAuthenticationSuccessHandler {

    private RequestCache requestCache = new HttpSessionRequestCache();

    @Override
    public void onAuthenticationSuccess(HttpServletRequest request, HttpServletResponse response,
            Authentication authentication) throws ServletException, IOException {
        SavedRequest savedRequest = requestCache.getRequest(request, response);

        if (savedRequest == null) {
            clearAuthenticationAttributes(request);
            return;
        }
        String targetUrlParam = getTargetUrlParameter();
        if (isAlwaysUseDefaultTargetUrl()
                || (targetUrlParam != null && StringUtils.hasText(request.getParameter(targetUrlParam)))) {
            requestCache.removeRequest(request, response);
            clearAuthenticationAttributes(request);
            return;
        }

        clearAuthenticationAttributes(request);
    }

    public void setRequestCache(RequestCache requestCache) {
        this.requestCache = requestCache;
    }
}
