将 grails 从 2.1.1 升级到 2.4.3

Question

我正在将一个 grails 应用程序从 2.1.1 升级到 2.4.3，而在升级过程中解决错误是一个永无止境的故事。

现在我被困在这一点上。

有什么办法解决这个问题吗？

谢谢！

我没有升级现有的 grails 应用程序，而是尝试创建一个新应用程序并将文件复制到新项目。这种方法会导致不同的错误。

grails 运行应用程序

使用的java版本：1.7.0_21

GRAILS_HOME=C:\PROGRA~2\grails\grails-2.4.3

GROOVY_HOME=C:\PROGRA~2\Groovy\groovy-2.3.6

Grails 版本：2.4.3

现在该怎么办？

谢谢！

----------------------------------------------- -----

根据以下建议删除对 bean 'grailsResourceLoader 的引用，我相应地更改了 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-2.5.xsd">

        <description>Grails application factory bean</description>
        <property name="grailsDescriptor" value="/WEB-INF/grails.xml" />
    </bean>

    </bean>

        </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>
</beans>

不幸的是，问题仍然存在。

感谢您的进一步帮助！

------------------------------------------

Grails 2.4.3 需要 Java 1.8.0 吗？

• 不，不是，即使对于 java 8，问题也是一样的

Answer 1

我能够通过创建一个新的 2.4 grails 项目并将 applicationContext.xml 文件从它复制到我现有的项目中来解决该问题。

Answer 2

您的新版本 Grails 不需要 applicationContent.xml 中的这两行：

<property name="grailsResourceLoader" ref="grailsResourceLoader" />

和

<bean id="grailsResourceLoader" class="org.codehaus.groovy.grails.commons.GrailsResourceLoaderFactoryBean" />

删除它们并重新启动您的项目。它应该可以正常工作。

Answer 3

对于任何感兴趣的人，通过将我的 Grails SDK 的位置从以下位置更改为我解决了这个问题：

C:\Program Files (x86)\Grails\grails-2.4.3

到

C:\Grails\grails-2.4.3

例如。通过删除 GRAILS_HOME 路径中的空格，如发现 here 的帖子中所述。

注意，通过设置 GROOVY_HOME = C:\PROGRA~2\Grails\grails-2.4.3 来删除空格是行不通的

Answer 4

我遇到了同样的错误，但是将 grails 升级到 2.5.5 版本，希望对您有所帮助。

在applicationContext.xml中：

<bean id="grailsApplication" class="org.codehaus.groovy.grails.commons.GrailsApplicationFactoryBean">
    <description>Grails application factory bean</description>
    <property name="grailsDescriptor" value="/WEB-INF/grails.xml" />
    <property name="grailsResourceLoader" ref="grailsResourceLoader" />
</bean>

删除 grailsResourceLoader，如下所示：

<bean id="grailsApplication" class="org.codehaus.groovy.grails.commons.GrailsApplicationFactoryBean">
    <description>Grails application factory bean</description>
    <property name="grailsDescriptor" value="/WEB-INF/grails.xml" />
</bean>
