Spring中JDBC插入數據后獲得該記錄的ID

Spring為自增長主鍵值數據庫中插入數據后，獲得該插入數據的ID的代碼示例：

                
          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()); 
          
     }
