Mybatis-There is no getter for property named 'id' in 'class java.lang.String'

 

<select id="findNoteByID" parameterType="string" resultType="note">  
        SELECT * FROM TABLE   
        <where>         
                      
            <choose>  
                <when test="id != null and id !='' ">id = #{id}</when>  
                <otherwise>1=2</otherwise>  
            </choose>  
        </where>  
</select>  

 

在测试时报错：There is no getter for property named 'id' in 'class java.lang.String'

 问题分析：Mybatis默认采用ONGL解析参数，所以会自动采用对象树的形式取string.id值，引起报错。

 解决方法：  public Note findNoteByID(@Param(value="id") String id);说明参数值。
