1、 Question
Error reporting result:
2、 Cause error code
The error I caused was caused in the Dao/studentdao.xml file, that is, the Dao configuration file of the persistence layer was written incorrectly. Here is my error code:
<select id="insertStudent"> insert into student1(name, age) values (#{name}, #{age}) </select>
The reason for the error is that it is easy for novices to make a mistake. Writing the inserted data label as the label of query data leads to an error
3、 Solution
Correct code
<insert id="insertStudent"> insert into student1(name, age) values (#{name}, #{age}) </insert>
