我有一個問題，試圖擴展一個groovy類。我已經擴展了一個groovy類，它通過構造文件路徑從Spring應用程序上下文文件加載，使用Spring的BeanDefinitionRegistry註冊bean，然後從應用程序上下文中檢索它。擴展groovy類導致運行時異常當檢索bean
private BeanDefinitionRegistry registry;
...
GenericBeanDefinition bd = new GenericBeanDefinition();
bd.setBeanClass(GroovyScriptFactory.class);
bd.setAttribute(
ScriptFactoryPostProcessor.REFRESH_CHECK_DELAY_ATTRIBUTE,
refreshDelay);
ConstructorArgumentValues cav = bd.getConstructorArgumentValues();
cav.addGenericArgumentValue(groovyLocation + WordUtils.capitalize(name)
+ ".groovy");
registry.registerBeanDefinition(name, bd);
...
// retrieve it
ExternalObject engine = (ExternalObject) this.applicationContext
.getBean(engineName);
這似乎除了當我向Groovy類，像這樣的工作好嗎：
Cat.groovy ：
package com.mycomp.external.engine;
import com.mycomp.external.ExternalObject;
public class Cat extends ExternalObject {
}
Lion.groovy
package com.mycomp.external.engine;
public class Lion extends Cat {
}
然後我得到一個錯誤的這種完全爛攤子：
Lion: 4: unable to resolve class Cat
@ line 4, column 1.
public class Lion extends Cat {
^
