如何在DBCP中使用（useUnicode = yes characterEncoding = UTF-8） [英] how to use (useUnicode=yes characterEncoding=UTF-8 ) with DBCP

问题描述

我正在尝试将阿拉伯字母插入到mysql数据库中，但它只存储????。我使用DBCP连接mysql数据库，这里是数据源：

I am trying to insert Arabic letter in to mysql database, but it only store "????". I am using DBCP for connecting with mysql databse, here is the datasource:

          <Resource name="jdbc/view_db" 
      auth="Container"
          type="javax.sql.DataSource"
          username="root" 
          password=""
          autoReconnect="true"
          testOnBorrow="true"
          validationQuery = "SELECT 1"
          driverClassName="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost/view_db"
          maxActive="50"
          maxIdle="10"/>

如何在DBCP配置中设置UTF-8编码或如何使用（useUnicode = yes characterEncoding = UTF-8）？

how to setup UTF-8 encoding with in DBCP configuration or how to use (useUnicode=yes characterEncoding=UTF-8 ) ?

推荐答案

根据 connectionProperties ，其值为 [propertyName = propertyValue;] * ，所以在你的情况下你应该使用类似的东西：

According to the DBCP documentation you need use the parameter connectionProperties with value [propertyName=propertyValue;]*, so in your case you should use something like:

      driverClassName="com.mysql.jdbc.Driver"
      url="jdbc:mysql://localhost/view_db"
      connectionProperties="useUnicode=yes;characterEncoding=utf8;"
      maxActive="50"
