Reference blog:  https://www.cnblogs.com/quan-coder/p/8387040.html

A: install the plug-in development tools:

Eclipse:

　　Download: https://projectlombok.org/download

　　Lombok.jar the downloaded file into eclipse installation path, the jar package is a jar file lombok plug, as shown below

     

　　Eclipse.ini then open the file, add the following:

　　　　-javaagent: lombok.jar

　　　　-Xbootclasspath/a:lombok.jar

 　　　　Restart eclipse

 

IDEA:

You can install plug-ins online lombok

settings -> plugins -> input in the search box lombok -> install

II: in pom.xml introduced dependence

<dependency>     <groupId>org.projectlombok</groupId>     <artifactId>lombok</artifactId>     <optional>true</optional> </dependency>

Then you can properly developed, the use of @Data lombok notes, you can simplify the Java code that can help us to automatically generate a set, get, toString () method

Create a java class, the final results are as follows:

import com.baomidou.mybatisplus.annotation.TableField;
import com.baomidou.mybatisplus.annotation.TableId;
import com.baomidou.mybatisplus.annotation.TableName;

import lombok.Data;
