java - 如何将变量从java文件传递到xml文件中查询的IN子句

Question

例如，

在java文件中，

String[] arrayTest= {"a", "b", "c"};
String strTest = "";
for (String test: arrayTest) {
    strTest = strTest + ", " + test;
}
strTest = strTest.substring(1);

在 xml 文件中，将变量传递给 IN 子句，如：

Where test in (#strTest#)

但它没有用。

Do you mean you are storing this SQL query in an XML file with some other XML data? You could use StringBuilder and a for loop to build up the required SQL query as a String.
