假设有个对象里有一个list<Object> listProperty 属性,要获取Object的类型:
Class<?> typeClass = field.getType(); if (List.class.isAssignableFrom(typeClass)) { Type fieldType = field.getGenericType(); if (fieldType instanceof ParameterizedType) { ParameterizedType paramType = (ParameterizedType) fieldType; Type[] genericTypes = paramType.getActualTypeArguments(); if (genericTypes != null && genericTypes.length > 0) { if (genericTypes[0] instanceof Class<?>) { Class<?> subType = (Class<?>) genericTypes[0]; } } } }
其中subType就是Object的对象类型。
