GroovySpring集成问题

spring groovy

GroovySpring集成问题,spring,groovy,Spring,Groovy,我们使用以下技术开发了一个应用程序： Struts 2.1 Springs 3.1 Groovy 1.8 Tomcat 6.0.26 - For deployment 我们的需求是将特定的应用程序层迁移到Groovy。我们已经将该层迁移到groovy，应用程序运行良好。迁移之后，groovy bean由spring容器正确初始化，但我们无法利用groovy的“动态语言”特性。也就是说，当我们修改Groovy脚本时，更新的更改不会动态地反映回应用程序作为参考，我附加了groovy脚本的

我们使用以下技术开发了一个应用程序：

Struts 2.1 
Springs 3.1 
Groovy 1.8 
Tomcat 6.0.26 - For deployment

我们的需求是将特定的应用程序层迁移到Groovy。我们已经将该层迁移到groovy，应用程序运行良好。迁移之后，groovy bean由spring容器正确初始化，但我们无法利用groovy的“动态语言”特性。也就是说，当我们修改Groovy脚本时，更新的更改不会动态地反映回应用程序

作为参考，我附加了groovy脚本的一个方法（GroovyConnection.groovy）：

Groovy上下文文件：

<?xml version="1.0" encoding="UTF-8"?> 
<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:lang="http://www.springframework.org/schema/lang"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-3.0.xsd">
<lang:defaults refresh-check-delay="2000"/>
<lang:groovy id="endPointManager" 
             script-source="classpath:GroovyConnection.groovy" refresh-check-delay="1000">
</lang:groovy>
</beans>

主要类别：

public static void main(String arg[]) {
 try {
        new GroovyShell().parse(newFile("test1.groovy")).invokeMethod("hello_world", null);              
    } catch (CompilationFailedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

根据我的理解，要么我们在springgroovy集成配置中缺少了允许我们刷新groovybeans修改的内容，要么Tomcat不允许我们刷新更新后的Groovy脚本

如果有人能提供任何建议，这将是有益的。提前谢谢

感谢所有花时间阅读我文章的人。问题解决了

实际上，我们同时使用@component和groovy-context.xml文件，因为我们面临这个问题。我已经删除了注释并将groovy文件放在类路径中。现在一切都按预期工作。Groovy bean得到了正确的刷新。但我无法使用spring注释实现同样的效果

现在我面临着另一个问题，我为此付出了很多努力。我有另一个GroovyBean，其中有我的所有静态方法（GroovyConnectionHelper.groovy）。我无法在GroovyConnection.script中调用这些静态方法。当应用程序执行application时，get挂起在执行到达GroovyConnectionHelper静态方法的位置

为了解决这个问题，我尝试在GroovyConnection中注入GroovyConnectionHelperBean，如下所示（这不是一个好方法）：

groovy-context.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"
           xmlns:lang="http://www.springframework.org/schema/lang"
           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/lang http://www.springframework.org/schema/lang/spring-lang-3.0.xsd">
    <lang:defaults refresh-check-delay="1000"/>
    <lang:groovy name="endPointManager" script-source="classpath:GroovyConnection.groovy">
         <lang:property name="groovyConnectionHelper" ref="groovyConnectionHelper"/>
    </lang:groovy>

    <lang:groovy id="groovyConnectionHelper" script-source="classpath:GroovyConnectionHelper.groovy"/>
</beans>

但这是行不通的。面对这个错误：

请建议我使用GroovyBean注入，或者直接调用Groovy静态方法。提前谢谢

这些问题非常具体，可能很难找到答案，但这里的文档对于遇到同样问题的人来说是无价的。即使你没有得到任何好的答案，也要继续努力！根据自我回答顶部对解决方案的描述，我投票以“打字错误/无法复制”结束这一问题。该答案的平衡并没有回答张贴的问题——这是一个新问题，因为它出现在答案中，所以作为一个问题没有受到关注。该用户已经缺席两年了，因此他们不太可能将其作为问题重新发布。
