收到异常: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弹簧安全性.发布3.1.2.RELEASE.如前所述，我已经像这样配置了security:http标记

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>

但是启动应用程序时出现此异常.如果删除安全配置，我的spring Web应用程序将正常运行.我在stackoverflow中也遇到了同样的问题.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

我认为问题的原因可能在于启动Web应用程序时未加载用于弹簧安全性的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>

如果您的配置文件位于类路径(不是WEB-INF文件夹或其子文件夹)中，则可以通过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>
...

另外，您还需要添加特殊的侦听器来加载配置文件:

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>
