The reference to entity "characterEncoding" must end with the ';' delimiter.
我在配置c3p0-config.xml时遇到一个问题：
<?xml version="1.0" encoding="UTF-8"?>
<c3p0-config>
<default-config>
<property name="driverClass">com.mysql.jdbc.Driver</property>
<property name="jdbcUrl">jdbc:mysql://localhost:3306/person?useUnicode=true&characterEncoding=utf8</property>
<property name="user">root</property>
<property name="password">123321</property>
<property name="acquireIncrement">2</property>
<property name="initialPoolSize">5</property>
<property name="minPoolSize">1</property>
<property name="maxPoolSize">5</property>
</default-config>
</c3p0-config>
标红的这一句配置出错！！
解决办法：
<property name="jdbcUrl">jdbc:mysql://localhost:3306/person?useUnicode=true&characterEncoding=utf8</property>
改为：
<property name="jdbcUrl">jdbc:mysql://localhost:3306/person?useUnicode=true&characterEncoding=utf8</property>
