mysql不支持PreparedStatement.setArray()的解决方案



查询中有in条件的时候mysql数据库不支持通过PreparedStatement.setArray()传递数组的方式设置参数，如：
PreparedStatement pstmt = conn.prepareStatement(“select * from table1 where id in (?)”);
Array array = conn.createArrayOf(“VARCHAR”, new Object[]{“1”, “2”,”3”});
pstmt.setArray(1, array);
ResultSet rs = pstmt.executeQuery();
运行后会报SQLFeatureNotSupportedException错误。

    private static void createQuery(List<String> taskIds) {
          String query = "select * from all_element t where t.task_id in (";
          StringBuilder queryBuilder = new StringBuilder(query);
           for ( int i = 0; i < taskIds.size(); i++) {
              queryBuilder.append( "?");
               if (i != taskIds.size() - 1)
                   queryBuilder.append( ",");
          }
          queryBuilder.append( ")");
           ps = con .prepareStatement(query);
           for ( int i = 1; i <= taskIds.size(); i++) {
               ps.setInt(i, taskIds.get(i - 1));
          }
           rs = ps .executeQuery();
     }
