连接到短信插件时出现 Grails 错误

Question

前两个文件是“SmsController.groovy”和“applicationContext.xml”，我认为它们会导致错误。

'SmsController.groovy'：

package nexmo

import grails.plugin.nexmo.NexmoException

class SmsControllerController {

// Inject the service
def nexmoService
def smsResult

def index() {

    try {
        // Send the message "What's up?" to 1-500-123-4567

        smsResult = nexmoService.sendSms("61451062006", "What's up?")
    }

        catch (NexmoException e) {
            // Handle error if failure
        }
    }
}

'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"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

</bean>

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

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

    <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" />

以下是我从新应用复制文件后遇到的错误。 （applicationContext.xml、sitemesh.xml 和一些 .tld 文件）：

Answer 1

这可能是由于包和文件所在目录不匹配。如果控制器在grails-app/controllers/nexmo/SmsController.groovy，则需要相应的包声明：

package nexmo

class SmsController {
   ...
}
