Spring 安全性：获取 NoSuchBean 异常错误

Question

我是 Spring 安全的新手，我正在使用 Spring 安全 4 开发 Spring 4。我已经按照一个教程开始，但每次我收到错误 NoSuchBeanDefinition found。 不知何故，我已经尝试了网络和 stackoverflow 上提到的所有建议，但无法弄清楚。

以下是我的应用程序的 sn-ps 以使用 Spring-Security。

}

执行后出现以下错误：

org.springframework.beans.factory.BeanCreationException: 错误 创建名为“org.springframework.security.filterChains”的bean： 无法解析对 bean 的引用 'org.springframework.security.web.DefaultSecurityFilterChain#0' 'org.springframework.security.authentication.dao.DaoAuthenticationProvider#0': 设置时无法解析对 bean 'userDetailsS​​ervice' 的引用 bean 属性 'userDetailsS​​ervice';嵌套异常是 org.springframework.beans.factory.NoSuchBeanDefinitionException: 否 定义了名为“userDetailsS​​ervice”的 bean

我可能缺少一些 xml 配置。但是经过这么多尝试弄清楚后，我发现它很困难。请帮我解决这个问题。

修改这个：

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/spring/appServlet/spring-security.xml </param-value>
</context-param>

<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- Processes application requests -->
<servlet>
    <servlet-name>appServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/spring/appServlet/servlet-context.xml, /WEB-INF/spring/appServlet/spring-security.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

Answer 2

您需要在servlet-context.xml中添加波纹管代码

<context:component-scan base-package="com.sparkle" />
<mvc:annotation-driven />

<bean id="userDetailsService"
    class="com.spring.service.MyUserDetailsService">
