安装Spring Security Plugin后，我的grails无法启动

Question

我正在使用Grails 2.4.2。我试图创建登录页面，但安装一个插件叫做春天的安全之后，我的Grails开始有错误：

| 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

这里是我的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"

    <property name="grailsDescriptor" value="/WEB-INF/grails.xml" /> 
</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" /> 

我不不知道问题出在哪里，即使我删除了Spring Security，它仍然会出现这个错误，任何人都会分享他们的解决方法吗？

由于类未找到异常，因此存在'grailsApplication'bean创建问题。而你的'grailsApplication'指向grails.xml。

xml中的手动bean定义过于复杂且不需要，因为grails会为您做。

我建议你重新设计的应用程序，如下所示：http://docs.grails.org/2.4.2/guide/single.html#gettingStarted
