最近一个物联网项目中遇到了java.sql.SQLException: Parameter index out of range的个问题.记下来:

模糊查询报错:

​java.sql.SQLException: Parameter index out of range ....

原因是sql语句错误.

 将

<if trip_bind="trip_no != null">  
         TRIP_NO like '%#{trip_no}%'

改为:

<if trip_bind="trip_no != null">  
      TRIP_NO like CONCAT('%','${trip_no}','%' ) 

问题解决.
