Method org/apache/commons/dbcp/DelegatingResultSet.isClosed()Z is abstract

按照网络上的排除建议，换成了alibaba的druid。

相关maven依赖如下，注意版本匹配问题

spring版本使用4.3.24.RELEASE

    </bean>

mybatis-spring.xml配置文件

<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
 
    <settings>
        <!--映射下划线风格到驼峰风格-->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    </settings>
    <typeHandlers>
        <typeHandler handler="org.apache.ibatis.type.InstantTypeHandler" />
        <typeHandler handler="org.apache.ibatis.type.LocalDateTimeTypeHandler" />
        <typeHandler handler="org.apache.ibatis.type.LocalDateTypeHandler" />
        <typeHandler handler="org.apache.ibatis.type.LocalTimeTypeHandler" />
        <typeHandler handler="org.apache.ibatis.type.OffsetDateTimeTypeHandler" />
        <typeHandler handler="org.apache.ibatis.type.OffsetTimeTypeHandler" />
        <typeHandler handler="org.apache.ibatis.type.ZonedDateTimeTypeHandler" />
    </typeHandlers>
</configuration>

如果遇到以上错误可能需要配置一下mybatis-spring.xml里面的

<settings>
     <!--映射下划线风格到驼峰风格-->
     <setting name="mapUnderscoreToCamelCase" value="true"/>
</settings>

至此问题解决
