run leaf demo

• setting application.properties

# setting leaf server url
codingapi.leaf-properties.leaf-url=http://127.0.0.1:8080/

• add Application @LeafAutoConfiguration

@LeafAutoConfiguration
@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class,args);
    }
}

LeafAutoConfiguration Specify LeafIdGenerate scanBasePackages

@LeafAutoConfiguration(scanBasePackages = {"com.example.demo"})

• implements LeafIdGenerate

import com.codingapi.leaf.framework.LeafIdGenerate;
import lombok.Getter;
import lombok.Setter;

/**
 * @author lorne
 * @since 1.0.0
 */
@Setter
@Getter
public class Demo implements LeafIdGenerate {

    private long id;

    private String name;

    public Demo() {
        id = this.generateLongId();
    }

}

• use generateLongId();

id = this.generateLongId();
LeafUtils.getInstance().generateId(Demo.class);
