由于mybatis的config.xml文件的resultmap匹配不上導致的
<mapper namespace="com.m.MGetBowersInfo">
<resultMap id="searchlog" type="com.b.SearchLog">
<result property="LocalName" column="LocalName" />
<result property="SearchTime" column="SearchTime" />
<result property="OperatingSystem" column="OperatingSystem" />
<result property="BrowserName" column="BrowserName" />
<result property="BrowserType" column="BrowserType" />
<result property="BrowserVersion" column="BrowserVersion" />
<result property="TerminalIp" column="TerminalIp" />
</resultMap>```
