java - 未定义名为 'shiroFilter' 的 bean

Question

我目前正在将 Shiro 嵌入到我的 Spring Web 应用程序中。

在web.xml中，我添加了:

    <filter>
        <filter-name>shiroFilter</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
        <init-param>
            <param-name>targetFilterLifecycle</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>

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

在 servlet-context.xml 中，我添加了:

    <beans:bean id="shiroFilter" name="shiroFilter" class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
        <beans:property name="securityManager" ref="securityManager"/>
        <beans:property name="filterChainDefinitions">
            <beans:value>
                # some example chain definitions:
                /admin/** = authc, roles[admin]
                /docs/** = authc, perms[document:read]
                /** = authc
                # more URL-to-FilterChain definitions here
            </beans:value>
        </beans:property>
    </beans:bean>

    <beans:bean id="securityManager" class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
        <beans:property name="realm" ref="myRealm"/>
    </beans:bean>

    <beans:bean id="myRealm" class="com.hersbitcloud.cancercloud.ShiroRealm">

    </beans:bean>

因为我还没有找到 JDBD 领域的解决方案，所以我只是将 AuthenticatingRealm 用作:

public class ShiroRealm extends AuthenticatingRealm {

    @Override
    protected AuthenticationInfo doGetAuthenticationInfo(AuthenticationToken arg0) throws AuthenticationException {
        // TODO Auto-generated method stub
        return null;
    }
}

但是，我遇到了以下异常:

org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'shiroFilter' is defined
    at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:698)

    at java.lang.Thread.run(Thread.java:745)

我该如何解决这个问题？

谢谢。

Answer 1

在 context-param 中添加 servlet-context.xml，如下所示:

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

不要将其放在 servlet contextConfigLocation 中
