对包含常规类的包使用反射时，“ org.reflections.Reflections-无法获得名称的类型”

时间：2019-05-06 13:30:04

标签： java intellij-idea groovy reflection spock

我有几个包含用@Issue注释的spock测试的常规类。我正在尝试使用反射来获取所有这些方法。 我在下面出现了异常>> 

CNDTR

这里是我到目前为止的代码：

我尝试了几种方法来实例化反射实例

1- 

Set<Method> TestMethodsList = new ReflectionsLibrary("package name here").getTestMethods()

2- 

reflections = new Reflections(new ConfigurationBuilder()
                 .setScanners(new SubTypesScanner(false /* don't exclude Object.class */), new ResourcesScanner(),new MemberUsageScanner(), new MethodAnnotationsScanner(), new MethodParameterScanner())
                 .setUrls(ClasspathHelper.forClassLoader(classLoadersList.toArray(new ClassLoader[0])))
                 .addClassLoader(this.getClass().getClassLoader())
                 .filterInputsBy(new FilterBuilder().include(FilterBuilder.prefix(packageName))))

然后我打电话

reflections = new Reflections(new ConfigurationBuilder().setUrls(ClasspathHelper.forPackage(packageName))
                .addScanners(new MemberUsageScanner(), new MethodAnnotationsScanner(), new MethodParameterScanner()))

在处理常规问题时，也许还有另一种使用反射的方法。顺便说一下，这段代码适用于Java类。

有什么想法吗？

谢谢

答案 0 :(得分：0)

好吧，我想我发现了我的问题。 我的课程以某种方式以“。”结尾。在末尾。因此，类加载器找不到它们。在没有多余点的情况下进行测试是可行的，所以我只想弄清楚将点添加到何处。
