mybaits错误解决：There is no getter for property named 'parentId ' in class 'java.lang.String'

在使用mybaitis传参数的时候，如果仅传入一个类型为String的参数，那么在 xml文件中应该使用_parameter来代替参数名。

比如mapper中如下方法，只有一个String值
public List<Group> findCityName(String id);
在xml中写法如下：
<select id="findCityName" resultType="com.ly.entity.background.Group">SELECT * from sys_group <where><if test="_parameter != 2"> 此处应该写成 _parameter，而不是parentIdparentId = #{0}</if><if test="_parameter == 2">  此处应该写成 _parameter，而不是parentIdparentId = 2 ORDER BY FIELD(id,316,127,186,164,356,273,226,28,396,3,313)</if></where></select>

如果写成parentId就会报：There is no getter for property named 'parentId ' in class 'java.lang.String'

知识点虽小，但实际解决了问题。在此处记录一下
