關於MySql鏈接url參數的設置 專題

報錯：

Establishing SSL connection without server's identity verification is not recommended. 

According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn't set. 

For compliance with existing applications not using SSL the verifyServerCertificate property is set to 'false'. 

You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.

解決辦法：
在jdbc.url上添加配置：

useSSL=true

eg:

jdbc.url=jdbc:mysql://localhost:3306/dbName?useUnicode=true&useSSL=true

一個在用的配置：

?useUnicode=true&useSSL=true&autoReconnect=true&failOverReadOnly=false

 

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/database?useUnicode=true&characterEncoding=utf8&autoReconnect=true&rewriteBatchedStatements=TRUE
jdbc.username=root
jdbc.password=password

database.url=jdbc:mysql://database_server:3306/oauth?autoReconnect=true&useUnicode=true&createDatabaseIfNotExist=true&characterEncoding=utf8&useSSL=true&serverTimezone=UTC

 

特別說明其中的jdbc.url配置：如果你已經升級好了mysql-connector，其中的characterEncoding=utf8可以被自動被識別為utf8mb4（當然也兼容原來的utf8），而autoReconnect配置我強烈建議配上，我之前就是忽略了這個屬性，導致因為緩存緣故，沒有讀取到DB最新配置，導致一直無法使用utf8mb4字符集，多么痛的領悟！！

沒有讓mysql驅動開啟批量執行sql的開關。

怎么開啟呢？在拼裝mysql鏈接的url時，為其加上allowMultiQueries參數，設置為true，如下：

jdbc.jdbcUrl=jdbc:mysql://127.0.0.1:3306/database?useUnicode=true&characterEncoding=utf8&allowMultiQueries=true

mysql JDBC URL格式如下： 

jdbc:mysql://[host:port],[host:port].../[database][?參數名1][=參數值1][&參數名2][=參數值2]... 

常用的幾個較為重要的參數： 

參數名稱                                         參數說明                                           缺省值                                                                                                                  最低版本要求 
user                                        數據庫用戶名（用於連接數據庫）                      所有版本 
passWord                                  用戶密碼（用於連接數據庫）                    所有版本 
useUnicode                            是否使用Unicode字符集，如果參數characterEncoding設置為gb2312或gbk，本參數值必須設置為true false 1.1g 
characterEncoding                當useUnicode設置為true時，指定字符編碼。比如可設置為gb2312或gbk false 1.1g 
autoReconnect                          當數據庫連接異常中斷時，是否自動重新連接？ false 1.1 
autoReconnectForPools              是否使用針對數據庫連接池的重連策略 false 3.1.3 
failOverReadOnly                        自動重連成功后，連接是否設置為只讀？ true 3.0.12 
maxReconnects                         autoReconnect設置為true時，重試連接的次數 3 1.1 
initialTimeout                               autoReconnect 設置為true時，兩次重連之間的時間間隔，單位：秒 2 1.1 
connectTimeout                             和數據庫服務器建立socket連接時的超時，單位：毫秒。 0表示永不超時，適用於JDK 1.4及更高版本 0 3.0.1 
socketTimeout                                socket操作（讀寫）超時，單位：毫秒。 0表示永不超時 0 3.0.1

對應中文環境，通常mysql連接URL可以設置為：

代碼如下:

jdbc:mysql://localhost:3306/test?user=root&password=&useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly=false 

在使用數據庫連接池的情況下，最好設置如下兩個參數： 

autoReconnect=true&failOverReadOnly=false 

需要注意的是，在xml配置文件中，url中的&符號需要轉義成   &  。
比如在tomcat的server.xml中配置數據庫連接池時，mysql jdbc url樣例如下： 

代碼如下:

jdbc:mysql://localhost:3306/test?user=root&password=&useUnicode=true&characterEncoding=utf8&autoReconnect=true&failOverReadOnly 

http://www.jb51.net/article/47764.htm

備注：mysql5以上的，設置autoReconnect=true 是無效的 只有4.x版本，起作用 

jdbc:mysql://127.0.0.1:3306/demo_ds?useServerPrepStmts=true&cachePrepStmts=true
設置參數useServerPrepStmts=true，這個參數的作用是讓MySQL服務進行prepare。沒有這個參數就是讓JDBC進行prepare，MySQL完全感知不到，是沒有什么意義的。
cachePrepStmts=true這個參數的意思是告訴JDBC緩存需要prepare的SQL

解決辦法1：
在jdbc.url上添加配置：

zeroDateTimeBehavior=convertToNull

eg:
jdbc.url=jdbc:mysql://localhost:3306/dbName?useUnicode=true&useSSL=true&zeroDateTimeBehavior=convertToNull

原因：

對於值為0000-00-00 00:00:00（默認值）的記錄，根據不同的配置，會返回不同的結果：
不配置：默認返回異常
zeroDateTimeBehavior=round 0001-01-01 00:00:00.0
zeroDateTimeBehavior=convertToNull null

解決方法2：
將日期"0000-00-00 00:00:00”改為正常日期即可。

關於"0000-00-00 00:00:00”：
在mysql中"0000-00-00 00:00:00”是作為一個特殊值存在的，但是在Java中， java.sql.Date 會被視為 不合法的值，被JVM認為格式不正確。

 

查詢的結果集中某數據行的日期值為0000-00-00 00:00:00。因MySQL的時間類型datetime范圍是1000-01-01 00:00:00 到 9999-12-31 23:59:59，所以報錯。
