安裝Spring Security Plugin後，我的grails無法啓動

Question

我正在使用Grails 2.4.2。我試圖創建登錄頁面，但安裝一個插件叫做春天的安全之後，我的Grails開始有錯誤：

| Error 2017-03-03 17:39:36,985 [localhost-startStop-1] ERROR context.ContextLoader - Context initialization failed 
Message: Error creating bean with name 'grailsApplication' defined in ServletContext resource [/WEB-INF/applicationContext.xml]: Invocation of init method failed; nested exception is org.codehaus.groovy.grails.exceptions.GrailsConfigurationException: Class not found loading Grails application: feedbackdemo.type

這裏是我的applicationContext.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</bean> 

<bean id="pluginManager" class="org.codehaus.groovy.grails.plugins.GrailsPluginManagerFactoryBean">

</bean> 

<bean id="grailsConfigurator" class="org.codehaus.groovy.grails.commons.spring.GrailsRuntimeConfigurator"> 
    <constructor-arg> 
     <ref bean="grailsApplication" /> 
    </constructor-arg> 
    <property name="pluginManager" ref="pluginManager" /> 
</bean> 

<bean id="characterEncodingFilter" class="org.springframework.web.filter.CharacterEncodingFilter"> 
    <property name="encoding"> 
     <value>utf-8</value> 
    </property> 
</bean> 

<bean id="conversionService" class="org.springframework.context.support.ConversionServiceFactoryBean" /> 

我不不知道問題出在哪裏，即使我刪除了Spring Security，它仍然會出現這個錯誤，任何人都會分享他們的解決方法嗎？

由於類未找到異常，因此存在'grailsApplication'bean創建問題。而你的'grailsApplication'指向grails.xml。

xml中的手動bean定義過於複雜且不需要，因爲grails會爲您做。

我建議你重新設計的應用程序，如下所示：http://docs.grails.org/2.4.2/guide/single.html#gettingStarted
