        values (#{num,jdbcType=VARCHAR}, #{cid,jdbcType=INTEGER},
        #{type,jdbcType=VARCHAR}, #{describe,jdbcType=VARCHAR}, #{solution,jdbcType=VARCHAR},
        #{sellerTel,jdbcType=VARCHAR}, #{sellerQq,jdbcType=VARCHAR}, #{sellerEmail,jdbcType=VARCHAR},
        #{buyerTel,jdbcType=VARCHAR}, #{buyerQq,jdbcType=VARCHAR}, #{buyerEmail,jdbcType=VARCHAR},
        #{submitTime,jdbcType=TIMESTAMP}, #{updateTime,jdbcType=TIMESTAMP}, #{rWrongId,jdbcType=INTEGER},
        #{ext1,jdbcType=VARCHAR}, #{ext2,jdbcType=VARCHAR}, #{img,jdbcType=LONGVARBINARY},#{state,jdbcType=INTEGER}
        )
    

useGeneratedKeys="true" keyProperty="id"

关键地方就是上面的两个配置

useGeneratedKeys 取值范围true|false 默认值是：false。 含义：设置是否使用JDBC的getGenereatedKeys方法获取主键并赋值到keyProperty设置的领域模型属性中。

keyProperty 取值为映射类主键属性的变量名
