Answer 1

--- Cause: com.ibatis.common.beans.ProbeException: There is no WRITEABLE property named 'A' in class 'com.ibatis.thrmes'
Caused by: com.ibatis.common.beans.ProbeException: There is no WRITEABLE property named 'A' in class 'com.ibatis.thrmes'   <result property="A" column="A"
   jdbcType="nvarchar" javaType="java.lang.String"
   />
   <result property="B" column="B"
    jdbcType="nvarchar" javaType="java.lang.String"
    />
    <result property="C" column="C"
   jdbcType="nvarchar" javaType="java.lang.String"
   />
   <result property="D" column="D"
    jdbcType="nvarchar" javaType="java.lang.String"
    />
    <result property="E" column="E" 
     jdbcType="nvarchar" javaType="java.lang.String"
    />将此处A、B、C、D、E，全部换成小写，应该就OK了。

Answer 2

private String A;
private String B;
private String C;
private String D;
private String E;这些也最好改成小写

Answer 3

小写应该是符合java 命名规范，以及javabean 命名规则
