grails - 连接SMS插件时出现Grails错误

Question

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

'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"

    <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" />

以下是从新应用程序复制文件后出现的错误。 (applicationContext.xml，sitemesh.xml和某些.tld文件):

Answer 1

这可能是由于软件包与文件所在目录之间的不匹配所致。如果 Controller 位于grails-app/controllers/nexmo/SmsController.groovy中，则需要相应的package语句:

package nexmo

class SmsController {
   ...
}
