Spring中JDBC插入数据后获得该记录的ID

Spring为自增长主键值数据库中插入数据后，获得该插入数据的ID的代码示例：

        
  public  
  void addForum( 
  final Forum forum) { 
  
          
  final String sql = "INSERT INTO t_forum(forum_name, forum_desc) VALUES(?,?)"; 
  
         KeyHolder keyHolder =  
  new GeneratedKeyHolder(); 
  
         getJdbcTemplate().update( 
  new PreparedStatementCreator() { 
  
              
  public PreparedStatement createPreparedStatement(Connection conn) { 
  
                 PreparedStatement ps = conn.prepareStatement(sql); 
  
                 ps.setString(1, forum.getForumName()); 
  
                 ps.setString(2, forum.getForumDesc()); 
  
                  
  return ps; 
  
             } 
  
         }, keyHolder); 
  
         forum.setForumId(keyHolder.getKey().intValue()); 
  
     }
