Spring Boot lombok

Lombok

project lombok is helper for bean.
getter, setter, validation, toString, etc…
We can reduce codes.

Install Lombok

Steps

• Install Lombok for IDE
• Add dependencies

I tried STS in Windows and Mac, and Eclipse in Mac.
Both are same ways to install.

STS

Need to match pom.xml and install IDE version.
Please download or find your maven repository lombok.jar.
If you already had java in your env, please double click lombok.jar

You can see following

By default, IDEs item is not there.
Press specify location and select your IDE. In STS case, fin “STS.ini”
After finding it, press install/update.

pom.xml

Next, you can add dependency in your pom.xml

<dependency>
  <groupId>org.projectlombok</groupId>
  <artifactId>lombok</artifactId>
  <version>1.16.6</version>
  <scope>provided</scope>
</dependency>

Example

SampleBean

@Data
public class SampleBean {

	private Integer id;
	
	private String name;
}

HelloController

@RestController
public class HelloController {

    @RequestMapping("/greeting")
    public String greeting() {
        SampleBean sm = new SampleBean();
	sm.setId(1); // Wow!	
        return "Test";
    }
}

We can use setId without setter in SampleBean class.
@Data has getter/setter feature
