Spring SqlRowSet使用JdbcTemplate将Clob作为字符串获取

Question

I have a QUERY column of type CLOB in database.

I am reading it in my program as:

SqlRowSet myRowSet = this.jdbcTemplate.queryForRowSet(this.sqlQuery);

while(myRowSet.next()){
   String currentClobString = myRowSet.getString("QUERY")
   System.out.println(currentClobString);
}

But this is giving the below output:

javax.sql.rowset.serial.SerialClob@7cfe7cfe

How can I correct this?

Thanks for reading!

Answer 1

You can call getObject(String columnLabel) method and use the IOutils from apache commons. This sample code is taken from another SO response.

    InputStream in = clobObject.getAsciiStream();
    StringWriter w = new StringWriter();
    IOUtils.copy(in, w);
    String clobAsString = w.toString();
