错误是这样说的:  
原因:org.apache.ibatis.type。TypeException:无法设置映射参数:ParameterMapping\{property=‘username’， mode=IN, javaType=class java.lang。  
错点::ParameterMapping  
就是下面代码里的parameterType这个参数写错了  
**注意注意**  
parameterType**在查询全部方法不需要这个参数，也就是没有**  
parameterType**添加返回的返回的是\*\*\*\*实体类的全类名**  
parameterType**在更新方法里，这个参数返回的也是实体类的全类名**  
parameterType**在删除方法里，这个参数返回的也是实体类的Integer,就是成功影响一条数据的记录表示成功**

<mapper namespace="com.shiyaxin.dao.IUserDao">
        
        <select id="findAll" resultType="com.shiyaxin.Bean.User">
            select * from user;
        </select>
        
        
        <insert id="saveUser" parameterType="com.shiyaxin.Bean.User">
    
            insert into user(username,birthday,sex,address) VALUES (#{username},#{birthday},#{sex},#{address});
        </insert>
        
    
        <update id="updateUser" parameterType="com.shiyaxin.Bean.User">
            UPDATE `user` set username=#{username},birthday=#{birthday},sex=#{sex},address=#{address} WHERE id=#{id}
        </update>
        
    
        <delete id="deleteUser" parameterType="Integer"> 
            DELETE FROM `user` WHERE id=#{uid}
        </delete>
        
    
        <select id="findOne" parameterType="INTEGER" resultType="com.shiyaxin.Bean.User">
    SELECT * FROM `user` where id=#{id}
        </select>
        
    
        <select id="findBlur" resultType="com.shiyaxin.Bean.User" parameterType="String">
    SELECT * FROM `user` WHERE  username LIKE #{usenname};
        </select>
        
    </mapper>
