将String数组传递给Prepared Statement Array(JDBC + SQLServer)

我试图将String数组传递给预准备语句,但是它返回了这个异常:

java.sql.SQLFeatureNotSupportedException: This operation is not supported.
    at com.microsoft.sqlserver.jdbc.SQLServerConnection.createArrayOf(SQLServerConnection.java:2763)
    at entity.dao.getRecords(Dao.java:168)
    at entity.dao.main(Dao.java:227)

我的代码是:

public List<Record> getRecords() throws SQLException {
        String sql = "select * from table where clause in (?)";

        PreparedStatement ps = this.connection.prepareStatement(sql);

        List<String> strings = new ArrayList<>();
        strings.add("string1");
        strings.add("string2");
        strings.add("string3");

        Array array = this.connection.createArrayOf("VARCHAR", strings.toArray());

        ps.setArray(1, array);

        ResultSet executeQuery = ps.executeQuery();
        List<Record> records = new ArrayList<Record>();
        Record record;
        while (executeQuery.next()) {
            // ...
        }
        return records;
    }

例外的行是Array array = this.connection.createArrayOf("VARCHAR", strings.toArray());

当我尝试创建数组时。

我已经搜索了如何传递数组,并且每个人都这样说,但似乎不能使用SQLServer。

您可以使用,或者,createQuery statemen(实体管理器)

String sql= "select * from Table table where table.clause IN :clauses"; 
Query query = em.createQuery(sql, Record.class);

List<String> strings = new ArrayList<>();
        strings.add("string1");
        strings.add("string2");
        strings.add("string3");

query.setParameter("clauses", strings );
List<Record> result= query .getResultList();
