Java編程入門(mén)分享，調(diào)用package，具體代碼如下：

public?String?executeSyncUser(String?operator)?throws?Exception?{
		Connection?conn?=?createConnection();
		String?flag?=?"1";
?
		CallableStatement?stmt?=?conn.prepareCall("{call?syncUser(?,?)}");
?
		//?stmt.setLong(1,?operator);
		stmt.setFloat(1,?Float.valueOf(operator));
		stmt.registerOutParameter(2,?Types.VARCHAR);?
?
		//?stmt.setInt(2,?flag);
		try?{
			System.out.println("用同步開(kāi)始時(shí)間"?+?System.currentTimeMillis());
			log.info("用戶同步開(kāi)始時(shí)間"?+?new?Date(System.currentTimeMillis()));
			stmt.execute();
			flag?=?stmt.getString(2);
			conn.commit();
			System.out.println("用戶同步結(jié)束時(shí)間"?+?System.currentTimeMillis());
			log.info("用戶同步結(jié)束時(shí)間"?+?new?Date(System.currentTimeMillis()));
		}?catch?(Exception?e)?{
			conn.rollback();
			throw?e;
		}?finally?{
			try?{
				if?(stmt?!=?null)?{
					stmt.close();
				}
				if?(conn?!=?null)?{
					releaseConnection(conn);
				}
			}?catch?(Exception?e)?{
				throw?e;
			}
		}
		return?flag;
	}
