获取异常：未定义名为“springSecurityFilterChain”的bean

Question

我正在从参考资料中学习spring security。版本3.1.2。释放如中所述，我已经像这样配置了安全性：http

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>

安全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>

但我在启动应用程序时遇到了这个异常。如果我删除了安全配置，我的spring web应用程序就会正常工作。我在stackoverflow中也遇到过同样的问题。但运气不好。

将此添加到您的网站。xml

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/root-context.xml, /WEB-INF/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>

        <!-- filter declaration for Spring Security -->
<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>

我刚刚在applicationContext中添加了bean定义。Spring提出的xml：

<bean id="springSecurityFilterChain" class="org.springframework.web.filter.DelegatingFilterProxy"/>

Answer 3

我认为您出现问题的原因可能是启动web应用程序时没有加载spring security的xml配置文件。

要解决这个问题，您应该在web中指定所有XML配置文件。类似的xml：

<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，则可以这样指定配置文件列表；

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

此外，您还需要添加特殊的侦听器来加载您的配置文件：

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