Mybatis-plus 's pit @ TableField does not work event regression

The entity class definition field is underlined

Fields in sql are also underlined.

Mybatiplus defaults to turning on automatic conversion of underscores, so the field is null.

The annotation @ TableField (value= "field name") does not take effect

Mybatis-plus: # mapper scan mapper-locations: classpath*:mapper/**/*.xml configuration: # turn off automatic hump conversion map-underscore-to-camel-case: false # print sql log-impl: org.apache.ibatis.logging.stdout.StdOutImpl@TableField

1. Only @ TableField is added, but MetaObjectHandler is not implemented.

2. The MetaObjectHandler implementation class is not added to the spring container

3. Fields marked with @ TableField have no get or set methods

4. The type of the field marked with @ TableField is not consistent with the type passed during binding. For example, if the field type is String and Integer is passed, it will become invalid.
