严重: Context [/SuperMarket] startup failed due to previous errors

2、错误原因

<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/supermarket?useUnicode=true&characterEncoding=UTF-8" />
<property name="username" value="root"></property>
<property name="password" value="root"></property>

     属性url中赋值时给的是：jdbc:mysql://localhost:3306/supermarket?useUnicode=true&characterEncoding=UTF-8，由错误提示可知是实体characterEncoding后面要添加“；”

     但是，添加了“；”后还是报这个错误

3、解决办法

<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/supermarket?useUnicode=true&amp;characterEncoding=UTF-8" />
<property name="username" value="root"></property>
<property name="password" value="root"></property>

     将";"转义下，转成“&"
