获取异常:未定义名为“springSecurityFilterChain"的 bean [英] getting exception: No bean named 'springSecurityFilterChain' is defined

问题描述

我正在从参考资料中学习 Spring Security.发布 3.1.2.RELEASE.如前所述，我已经像这样配置了 security:http 标签

I am learning spring security from reference material. release 3.1.2.RELEASE. As stated in that I have configured security:http tag like this

security-context.xml

<security:http auto-config="true">
        <security:intercept-url pattern="/**" access="ROLE_USER"/>
    </security:http>

web.xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:*-context.xml</param-value>
  </context-param>

  <filter>
    <filter-name>springSecurityFilterChain</filter-name>
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
  </filter>

  <filter-mapping>
    <filter-name>springSecurityFilterChain</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <servlet>
    <servlet-name>security</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>security</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

security-servlet.xml

<context:component-scan base-package="com.pokuri.security.mvc.controllers"/>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
        <property name="prefix" value="/WEB-INF/page/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

但是当我启动应用程序时出现此异常.如果我删除安全配置，我的 Spring Web 应用程序工作正常.我在 stackoverflow 中遇到了同样的问题.但没有运气.

But I am getting this exception when I start the application. If I remove security configuration my spring web application working fine. I went through the same kind of questions in stackoverflow. But no luck.

推荐答案

我认为您的问题的原因可能在于您启动 Web 应用程序时未加载用于 spring 安全性的 xml 配置文件.

I think that the reason of your problem can be in that your xml configuration file for spring security isn't loaded when you start your web app.

要解决此问题，您应该像这样在 web.xml 中指定所有 XML 配置文件:

To fix this you should specify all your XML config files in web.xml like that:

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

如果您的配置文件在类路径(不是 WEB-INF 文件夹或其子文件夹)中，那么您可以以这种方式指定配置文件列表；

If you have your config files in classpath (not WEB-INF folder or it's subfolders) then you can specify list of config files in such way;

...
<param-value>
    classpath:applicationContext.xml,
    classpath:spitter-security.xml
</param-value>
...

而且你还需要添加特殊的监听器来加载你的配置文件:

And also you need to add special listener that will load your config files:

<listener>
    <listener-class>
        org.springframework.web.context.ContextLoaderListener
    </listener-class>
</listener>
