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。
