org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: There is no getter for property named ‘investTime‘ in ‘class java.lang.String‘

錯誤寫法：

<if test="investDate!=null and investDate!=‘‘">
    AND invest.addtime LIKE CONCAT(‘%‘,#{investDate},‘%‘)
</if>

正確寫法：

<if
 
 test="_parameter!=null and _parameter!=‘‘">
      AND invest.addtime LIKE CONCAT(‘%‘,#{_parameter},‘%‘)
</if>

總結：

如果不用if test來判斷的話，不管哪種寫法都不會報錯！建議都用_parameter來寫，多參數用Map或者封裝一個bean來做參數

There is no getter for property named 'xxx' in 'class java.lang.String
