1 DB2資料庫操作 2 1、表增加欄位 3 ALTER TABLE 表名 ADD COLUMN 欄位名 VARCHAR(2); 4 5 表增加帶預設值0的欄位 6 ALTER TABLE 表名 ADD COLUMN 欄位名 VARCHAR(1) WITH DEFAULT '0'; 7 8 查詢時某個欄位值為null，替換成其他值 9 CASE WHEN 欄位名 NULL THEN '0' ELSE 欄位名 END 欄位名 10 11 更改欄位長度 12 alter table TF2M_ARAP_FUNDS alter RECEIPT_NUM set data type varchar(20);13 14 --DB2 Create UUID 32 32-bit lowercase 15 SELECT concat (hex (RAND ()), hex (RAND ())) as uuid FROM SYSIBM.SYSDUMMY1; 16 SELECT lower(hex(RAND())||hex(RAND())) as uuid FROM sysibm.sysdummy1; 17 18 Oracle資料庫操作 19 1、表字段新增 20 ALTER TABLE 表名 ADD 欄位名 VARCHAR(2); 21 22 2、更新表字段 23 ALTER TABLE 表名 MODIFY 欄位名 NOT NULL/NULL;24 25 --Orcale Create UUID 32 32-bit lowercase 26 select lower(sys_guid()) from dual; 27 SELECT RAWTOHEX(SYS_GUID()) FROM DUAL; 28 29 mybatis中update動態新增 30 31 <update id="updateTfPayoutBankExtra" parameterClass="java.util.HashMap"> 32 UPDATE MYIVR_TUSER 33 <dynamic prepend="SET "> 34<isNotEmpty property="depositFlag" prepend=" "><![CDATA[ NOTICE_DEPOSIT_FLAG = #depositFlag# ]]></isNotEmpty> 35 <isNotEmpty property="depositAccount" prepend=","><![CDATA[ NOTICE_DEPOSIT_ACCOUNT = #depositAccount# ]]></isNotEmpty> 36 </dynamic> 37 <dynamic prepend="WHERE"> 38 EXTRA_ID = #id# 39 </dynamic> 40 </update> 41 42 mybatis中delete 批量刪除 43 <delete id="deletePackagePriceInstall" parameterClass="java.util.HashMap"> 44 DELETE FROM INF_HS_PACKAGE_PRICE A 45 WHERE 46 1=1 47 <isNotEmpty prepend="and" property="id"> 48 <iterate property="id" conjunction="OR"> 49 A.ID = '$id[]$' 50 </iterate> 51 </isNotEmpty> 52 </delete>
1 //1、生成5位隨機數 2 String requestSn = ""; 3 for(int n=0;n<10;n++ ) { 4 requestSn += (int)(10*(Math.random())); 5 }//end 6 requestSn = requestSn.substring(0,5); 7 8 //2、清除Hibernate的快取物件 9 this.getBasDAO().getHibernateTemplate().evict(entity); 10 11 //3、在Tomcat目錄下的server.xml中加下面的專案啟動資料夾和路徑配置 12 <Context docBase="D:\project\RiDolPlatform2.7.2workspace3.4.2\TRA\MyTest02\WebContent" path="/TFM" reloadable="false"/></Host> 13 14 //4、在Tomcat目錄下的content.xml中加下面資料庫的資料來源配置 15 <Resource auth="Container" driverClassName="com.ibm.db2.jcc.DB2Driver" maxActive="5" maxIdle="30" maxWait="10000" name="WFISDB" password="123456" type="javax.sql.DataSource" url="jdbc:db2://172.27.1.192:50000/TEST01" username="db2admin"/> 16 17 //5、加大jvm的執行空間 18 -Xms256m -Xmx1024m -XX:PermSize=128M -XX:MaxNewSize=128m -XX:MaxPermSize=256m 19 20 //6、調整控制檯日誌輸出的時間 21 -Duser.timezone=GMT+08 22 23 //7、更改eclipse編碼設定 24 Windows --> General --> Content Types --> Text
1、姓名脫敏規則: 方式一：只顯示第一個漢字,比如李某某置換為李**, 李某置換為李* private static String desensitizedName(String fullName){ if (!Strings.isNullOrEmpty(name)) { String name = StringUtils.left(fullName, 1); return StringUtils.rightPad(name, StringUtils.length(fullName), "*"); } return name; } 方式二：名字是兩位時: 張三--> 張* ，名字是三位及以上時: 燕雙鷹 --> 燕*鷹 if (fullname.length() == 2){ name = fullname.replaceAll(".$", "*"); }else if (fullname.length() > 2){ name = fullname.replaceAll("(?<=.).(?=.)", "*"); } 2、手機號脫敏規則: 保留前三後四, 比如15638296218置換為156****6218 private static String desensitizedPhoneNumber(String phoneNumber){ if(StringUtils.isNotEmpty(phoneNumber)){ phoneNumber = phoneNumber.replaceAll("(\\w{3})\\w*(\\w{4})", "$1****$2"); } return phoneNumber; } 3、身份證號脫敏規則: 保留前六後三, 適用於15位和18位身份證號 （1）方式一：需要判斷身份證號位數 private static String desensitizedIdNumber(String idNumber){ if (!Strings.isNullOrEmpty(idNumber)) { if (idNumber.length() == 15){ idNumber = idNumber.replaceAll("(\\w{6})\\w*(\\w{3})", "$1******$2"); } if (idNumber.length() == 18){ idNumber = idNumber.replaceAll("(\\w{6})\\w*(\\w{3})", "$1*********$2"); } } return idNumber; } 方式二：前面StringUtils.left裡面的長度6和後面的6個*的個數是對應的 private static String desensitizedIdNumber(String idNumber){ if (!Strings.isNullOrEmpty(idNumber)) { return StringUtils.left(idNumber, 6).concat(StringUtils.removeStart(StringUtils.leftPad(StringUtils.right(idNumber, 3), StringUtils.length(idNumber), "*"), "******")); } return idNumber; }
