Introduction

Spring Boot is a very efficient development framework, lombok is a set of code template solution, will greatly improve the efficiency of development, here is introduced to you to use.

Lombok wants to solve a large number of Getter/Setter methods in our entity Bean, as well as toString, hashCode and so on may not be used, but sometimes still need to be copied in order to facilitate the use of methods; after the use of Lombok, it will automatically help you to achieve code generation, note that it is in the process of running, to help you automatically generate. That is, it will greatly reduce the total amount of your code.

First, add the lombok.jar dependency in the pom.xml file of the project. You only need to fill in groupid and artifactid. The version and scope have been defined in the parent project boot project.

Org.projectlombok lombok

Then download lombok.jar and download it in order to install lombok into ide and run it in cmd.

I run directly to the download directory of lombok, and I can also run it directly in other directories. I need to execute the command: download directory of java-jar lombok.jar + lombok.jar

Then your IDE installation screen will pop up, and if you have more than one IDE, you will have more than one choice, choose the version of IDE you are using. Note that this is the way eclipse is installed, and ldea does not seem to work.

Finally, go to your IDE installation directory to check the ini file. If you have the-javaagent:lombok.jar code, it means that the installation has been successful.

Introduction of common notes

@ Getter/ @ Setter: you can act on a class and a property, and if you put it on a class, you will generate a Getter/Setter method for all non-static (non-static) properties, and if you put it on a property, you will generate a Getter/Setter method for that property. And you can specify the access level of the Getter/Setter method.

EqualsAndHashCode: by default, all non-transient (non-transient) and non-static (non-static) fields are used to generate equals and hascode methods, or you can specify which properties to use. @ ToString generates the toString method, which, by default, outputs the class name and all attributes, which are output sequentially, separated by commas.

@ NoArgsConstructor, @ RequiredArgsConstructor and @ AllArgsConstructor: no parameter constructor, partial parameter constructor, full parameter constructor

Data: contains @ ToString, @ EqualsAndHashCode, @ Getter for all attributes, and a combination of @ Setter and @ RequiredArgsConstructor for all non-final attributes. In general, this annotation is basically sufficient.

@ Budilder: it can be initialized in Builder mode.

Slf4j: equivalent to: private final Logger logger = LoggerFactory.getLogger (XXX.class); it couldn't get any better! Generally used on other java classes
