一直报错，错误如下
严重: Servlet.service() forservlet [mvc-dispatcher] in context with path [/smallProject] threw exception[Request processing failed; nested exception isorg.springframework.jdbc.BadSqlGrammarException:

网上搜索一番，发现这需要修改数据源连接配置
比如：jdbc:mysql://192.168.1.236:3306/test?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
但是我数据源配置在xml中，报The reference to entity "allowMultiQueries" must end withthe ';' delimiter.错误
<propertyname="url"value="jdbc:mysql://localhost:3306/xiaorui?characterEncoding=UTF-8&allowMultiQueries=true"/>
<property name="username"value="root" />
<property name="password"value="123456" />
<propertyname="driverClassName" value="com.mysql.jdbc.Driver" />
原来&等特殊符号在xml中需要转义
| < |
< |
小于号 |
| > |
> |
大于号 |
| & |
& |
和 |
| ' |
' |
单引号 |
| " |
" |
双引号 |
修改如下
<propertyname="url"value="jdbc:mysql://localhost:3306/xiaorui?characterEncoding=UTF-8&allowMultiQueries=true" />
<property name="username"value="root" />
<property name="password"value="123456" />
<property name="driverClassName"value="com.mysql.jdbc.Driver" />
但是这样批量更新返回的影响行数就为1
