springMVC shiro報錯No SecurityManager accessible to the calling code

 跳轉網頁 控制檯報錯

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.apache.shiro.UnavailableSecurityManagerException: No SecurityManager accessible to the calling code, either bound to the org.apache.shiro.util.ThreadContext or as a vm static singleton.  This is an invalid application configuration.

排查順序

1，https://jingyan.baidu.com/article/3d69c551625a97f0cf02d7b3.html

web.xml里加入shiroFilter 且shiroFilter應該放在

servlet

的前面。

2，將

ShiroFilter  寫完整

 <!-- ShiroFilter start -->
<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>
   <dispatcher>REQUEST</dispatcher>
   <dispatcher>FORWARD</dispatcher>
   <dispatcher>INCLUDE</dispatcher>
   <dispatcher>ERROR</dispatcher>
</filter-mapping>
<!-- ShiroFilter end -->
