通过反射获取列表属性里保存的对象类型

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];
                        }
               }
       }
}
