利用GeneratedKeyHolder获得新增数据主键值

 1 public Role createRole(final Role Role) {
 2         final String sql = "insert into sys_roles(role, description, available) values(?,?,?)";
 3 
 4         GeneratedKeyHolder keyHolder = new GeneratedKeyHolder();
 5         jdbcTemplate.update(new PreparedStatementCreator() {
 6             @Override
 7             public PreparedStatement createPreparedStatement(Connection connection) throws SQLException {
 8                 PreparedStatement psst = connection.prepareStatement(sql, new String[] { "id" });
 9                 psst.setString(1, Role.getRole());
10                 psst.setString(2, Role.getDescription());
11                 psst.setBoolean(3, Role.getAvailable());
12                 return psst;
13             }
14         }, keyHolder);
15         Role.setId(keyHolder.getKey().longValue());
16 
17         return Role;
18     }
