我有两节课. One.groovy:
class One {
One() {}
def someMethod(String hey) {
println(hey)
}
}
和Two.groovy:
class Two {
def one
Two() {
Class groovy = ((GroovyClassLoader) this.class.classLoader).parseClass("One.groovy")
one = groovy.newInstance()
one.someMethod("Yo!")
}
}
我用这样的东西实例化了两个:
GroovyClassLoader gcl = new GroovyClassLoader();
Class cl = gcl.parseClass(new File("Two.groovy"));
Object instance = cl.newInstance();
但现在我得到了groovy.lang.MissingMethodException:没有方法签名:script13561062248721121730020.someMethod()适用于参数类型:(java.lang.String)值:[Yo!]
有任何想法吗?
最佳答案 看起来它是由于调用groovy类加载器方法而发生的:
string one是以文本格式解析脚本.使用文件一个在这里工作:
class Two {
def one
Two() {
Class groovy = ((GroovyClassLoader) this.class.classLoader).parseClass("One.groovy")
assert groovy.superclass == Script // whoops, not what we wanted
Class groovy2 = ((GroovyClassLoader) this.class.classLoader).parseClass new File("One.groovy")
one = groovy2.newInstance()
assert one.class == One // now we are talking :-)
one.someMethod("Yo!") // prints fine
}
}
