code: public static Object[] getSqlParams(String sqlPattern, Map map) {
          Object[] sqlParams = JdbcPatternUtil.getValues(JdbcPatternUtil.getCamelKeys(sqlPattern), map).toArray();
          for (int i = 0; i < sqlParams.length; i++) {
              if (sqlParams[i] instanceof Calendar) {//因为prepared statement不支持calendar类型,所以需要将其其中的calendar转为date
                  sqlParams[i] = ((Calendar) sqlParams[i]).getTime();
              }
          }
          return sqlParams;
      }
