其中我将dao持久层下的xml配置文件中parameterType参数类型写成了id,应该是String类型,可以省略不写的,其导致的结果是访问网页响应404错误.(一般出现这种问题大多与配置文件错误有关)

<select id="queryAllClueById" parameterType="id" resultType="clue">
select * from tbl_clue where id = #{id}
</select>

改为String,或者删除不写传入参数类型后程序正常.

以下为个人看法,因为mybatis映射的配置文件错误,所以导致整个持久层处理数据库错误,所以在服务器启动时监听器加载过程中,无法正常访问数据库文件,产生以上关于监听器的错误信息.

本来是个小问题的,看错误记录也很容易发现,是参数类型写错,结果因为自己没有看全后面的信息,费了一会功夫..检查了半天的web.xml和mybatis.xml
