今天興致來了，說要在家搞搞平臺的東西，nnd，竟然遇到了莫名其妙的mysql亂碼問題，其實不是mysql的問題，是jdbc數據源的鏈接沒有指明字符集的問題，記下來備用：
<datasource jta="false" jndi-name="java:jboss/datasources/MySqlDS" pool-name="bdp" enabled="true" use-java-context="true" use-ccm="true"> <connection-url>jdbc:mysql://localhost:3306/bdp-dev?useUnicode=true&characterEncoding=utf8</connection-url>
<driver>com.mysql</driver>
<pool>
<min-pool-size>10</min-pool-size>
<max-pool-size>100</max-pool-size>
<prefill>true</prefill>
<use-strict-min>false</use-strict-min>
<flush-strategy>FailingConnectionOnly</flush-strategy>
</pool>
<security>
<user-name>root</user-name>
</security>
<statement>
<prepared-statement-cache-size>32</prepared-statement-cache-size>
<share-prepared-statements>true</share-prepared-statements>
</statement>
</datasource>
