Re: "No bean named 'shiroFilter' available" when try to integrate shiro with spring boot

Hi,

When specified <context-param> and <listener> in web.xml, following exceptions 
was caught.

05-Jun-2017 17:11:40.306 INFO [main] 
org.apache.catalina.core.ApplicationContext.log Initializing Spring embedded 
WebApplicationContext
05-Jun-2017 17:11:42.286 SEVERE [main] 
org.apache.catalina.core.StandardContext.listenerStart Exception sending 
context initialized event to listener instance of class 
[org.springframework.web.context.ContextLoaderListener]
 java.lang.IllegalStateException: Cannot initialize context because there is 
already a root application context present - check whether you have multiple 
ContextLoader* definitions in your web.xml!

org.springframework.web.context.ContextLoader.initWebApplicationContext(ContextLoader.java:296)

org.springframework.web.context.ContextLoaderListener.contextInitialized(ContextLoaderListener.java:107)
        at 
org.apache.catalina.core.StandardContext.listenerStart(StandardContext.java:4734)


Acutally I used annotation of "@SpringBootApplication"  as below,

@SpringBootApplication

public class AdminBoard {

    public static void main(String[] args) throws Exception {
         SpringApplication.run(AdminBoard.class, args);
    }

}

Hi,

Did spring start up at all? You do not have it in your web.xml...


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

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

Hi guys,

I tried to integrate shiro with spring boot by following document in Apache 
shiro.

I found a problem when trying to deploy war to tomcat as below:

04-Jun-2017 16:16:00.163 INFO [main] 
org.apache.catalina.core.ApplicationContext.log Initializing Shiro environment
04-Jun-2017 16:16:00.448 SEVERE [main] 
org.apache.catalina.core.StandardContext.filterStart Exception starting filter 
[shiroFilter]

'shiroFilter' available
        at 
org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:687)
        at

        at 
org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:284)


According to shiro document, I should add applicationContext.xml with proper 
settings. Where should I place the context file? In WEB-INF or other directory?


How could I fix this problem?


Detailed configuration is as below,


Web.xml in directory WEB-INF is as following,

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee";
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
         xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
              http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd";>
    <!-- configuration for Aapache shiro -->
    <listener>
        
<listener-class>org.apache.shiro.web.env.EnvironmentLoaderListener</listener-class>
    </listener>

    <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>

</web-app>


applicationContext.xml is placed in folder WEB-INF, and content is as below,

<bean id="shiroFilter" 
class="org.apache.shiro.spring.web.ShiroFilterFactoryBean">
    <property name="securityManager" ref="securityManager"/>
    <property name="filterChainDefinitions">
        <value>/dashboard/users/list = authc, roles[admin]</value>
    </property>
</bean>

<bean id="securityManager" 
class="org.apache.shiro.web.mgt.DefaultWebSecurityManager">
    <!-- Single realm app.  If you have multiple realms, use the 'realms' 
property instead. -->
    <property name="realm" ref="myRealm"/>
    <!-- By default the servlet container sessions will be used.  Uncomment 
this line
         to use shiro's native sessions (see the JavaDoc for more): -->
    <!-- <property name="sessionMode" value="native"/> -->
</bean>
<bean id="lifecycleBeanPostProcessor" 
class="org.apache.shiro.spring.LifecycleBeanPostProcessor"/>

<!-- Define the Shiro Realm implementation you want to use to connect to your 
back-end -->
<!-- security datasource: -->
<bean id="myRealm" class="org.apache.shiro.realm.jdbc.JdbcRealm">
</bean>
<bean 
class="org.springframework.aop.framework.autoproxy.DefaultAdvisorAutoProxyCreator"
 depends-on="lifecycleBeanPostProcessor"/>
    <bean 
class="org.apache.shiro.spring.security.interceptor.AuthorizationAttributeSourceAdvisor">
    <property name="securityManager" ref="securityManager"/>
</bean>
</beans>
