Reason: The field of the incoming parameter is a null object, and the corresponding jdbcType type cannot be obtained, and an error is reported.

 

Solution:

1. Specify the insert value jdbcType, and change the sql to  insert into user(id,name) values(#{id,jdbcType=VARCHAR},#{name,jdbcType=VARCHAR}) 

 

2. Configure it in the mybatis-config.xml file and add the settings configuration, as follows: (recommended)

<configuration>

<settings>

    <setting name="jdbcTypeForNull" value="NULL" />

</settings>

</configuration>

 

normal operation.
