错误-数据提供程序必须返回对象[][]或迭代器&；书信电报；对象&；燃气轮机；[]，而不是类[[Ljava.lang.Object；

尝试从excel工作表读取数据时出错。我的环境是-POI3.10JAR，Java1.8，window

[Error] org.testng.TestNGException: 
Data Provider public static java.lang.Object[][] mytestpackage.DataProvi.CustomerCreation() throws java.lang.Exception must return either Object[][] or Iterator<Object>[], not class [[Ljava.lang.Object;
    at org.testng.internal.MethodInvocationHelper.invokeDataProvider(MethodInvocationHelper.java:133)

这是我的数据提供者代码

   @DataProvider

    public static Object[][] CustomerCreation() throws Exception{

         Object[][] testObjArray = ExcelUtils.getTableArray("E://TT//src//utility//TestData.xlsx","Sheet1");

         return (testObjArray);

        }

数据提供程序实现的代码：

@Test(dataProvider="CustomerCreation")

    public void Registration_data(String Sr, String ssn) throws  Exception{

请让我知道我哪里出错了

Excel实用程序代码：-

   }

请共享

ExcelUtils

类代码。感谢回复Naveen，刚刚添加了Excel实用程序代码。请检查代码。请同时添加

TestData.xlsx

文件。我尝试了上述代码。但是，由于以下原因导致出现了另一个错误：

：org.apache.poi.openxml4j.exceptions.InvalidFormatException:包应该包含一个内容键入part[M1.13]

您使用哪种TestNG版本？您可以尝试使用最新版本（6.10）吗？我使用的是poi的3.10版本。我确实遇到了类似的问题openxml4j.jar丢失。请添加此jar
