The reference to entity "characterEncoding" must end with the ';' delimiter

数据源配置时加上编码转换格式后出问题了:

The reference to entity "characterEncoding" must end with the ';' delimiter

这个错误就是 context.xml中设置数据源链接URL的问题<bean id="mysql" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
          <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/wljr?zeroDateTimeBehavior=convertToNull&characterEncoding=utf8"/>

   <property name="user" value="root"/>
          <property name="password" value="root"/>
          <property name="minPoolSize" value="2" />
          <property name="maxPoolSize" value="20"/>
          <property name="initialPoolSize" value="5"/>
       </bean>

 

正确的如下:

<bean id="mysql" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
           <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/wljr?zeroDateTimeBehavior=convertToNull&amp;characterEncoding=utf8"/>

    <property name="user" value="root"/>
           <property name="password" value="root"/>
           <property name="minPoolSize" value="2" />
           <property name="maxPoolSize" value="20"/>
           <property name="initialPoolSize" value="5"/>
      </bean>

 

这大概是由xml文件中的编码规则决定要这么变换。

在xml文件中有以下几类字符要进行转义替换:

 

&lt;

 

<

 

小于号

 

&gt;

 

>

 

大于号

 

&amp;

 

&

 

 

&apos;

 

'

 

单引号

 

&quot;

 

"

 

双引号
