Spring: jdbcTemplate獲取剛插入記錄的主鍵id

Spring jdbcTemplate獲取剛插入記錄的主鍵id

1. JdbcTemplate

JdbcTemplate jdbcTemplate1 = new JdbcTemplate(dataSource);
    	
    	final String sql = " INSERT INTO FUND_AGGREGATION_TEMP ( " 
    			+ " ID, ORDER_NO, BUSINESS_TYPE, TYPE, "
    			+ " OFFSET_NUM, CREATE_TIME, UPDATE_TIME  ) "
    			+ "  VALUES ( -2,  '1',  '1',  '1',  ?,  CURRENT TIMESTAMP, CURRENT TIMESTAMP  ) ";
		KeyHolder keyHolder1 = new GeneratedKeyHolder();  
		jdbcTemplate1.update(new PreparedStatementCreator() {
			
			@Override
			public PreparedStatement createPreparedStatement(Connection con)
					throws SQLException {
                                 //設置返回的主鍵字段名
				PreparedStatement ps = con.prepareStatement(sql,new String[]{ "ID" }); 
				ps.setLong(1, 0);
				return ps;
			}
		}, keyHolder1);
		
		int a = keyHolder1.getKey().intValue();
		System.out.println(a);
		LOG.info("返回主鍵："+ a);

2. NamedParameterJdbcTemplate

NamedParameterJdbcTemplate jdbcTemplate = new NamedParameterJdbcTemplate(dataSource);
    	
    	final String sql = " INSERT INTO FUND_AGGREGATION_TEMP ( " 
    			+ " ID, ORDER_NO, BUSINESS_TYPE, TYPE, "
    			+ " OFFSET_NUM, CREATE_TIME, UPDATE_TIME  ) "
    			+ "  VALUES ( -2,  '1',  '1',  '1',  :offsetNum,  CURRENT TIMESTAMP, CURRENT TIMESTAMP  ) ";
    	MapSqlParameterSource parameters = new MapSqlParameterSource();
    	parameters.addValue("offsetNum", 0);
    	
    	KeyHolder keyHolder = new GeneratedKeyHolder();  
    	
        int autoIncId = 0;  
          
        jdbcTemplate.update( sql, parameters, keyHolder, new String[] {"ID" }); 
        autoIncId = keyHolder.getKey().intValue();  
        
		System.out.println(autoIncId);
		LOG.info("返回主鍵："+ autoIncId);
