title: How to implement RowMapper using java lambda expression
body: <p>I had a working RowMapper code that maps database table row in to a java object. I wanted to change the implementation using lambda expression. However, I am always getting error; Code snippet as follows;</p>
  
  <pre><code>String queryString = "select * from person where person_id = ? ";
  RowMapper rowMapper = (rs, rowNum) -&gt; {
  
  Person p = new Person();
  
  p.setName(rs.getString("personName"));
  p.setAddress(rs.getString("address"));
  p.setAge(rs.getInt("age"));
  }
  
  Person person = getJdbcTemplate().query(queryString, personId, rowMapper);
  
  return person;
  </code></pre>
  
  <p>Can someone help me to implement code correctly?
  Any idea to get list of persons?</p>
