Java enum and toString() 구현

자바 enum 클래스와 apache common-lang3  의 ToStringBuilder 를 사용하여 toString 메서드 구현 (멀티라인 처리용)

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;
import org.apache.commons.lang3.builder.ToStringBuilder;
import org.apache.commons.lang3.builder.ToStringStyle;

/**
 * @author gavin
 */
@AllArgsConstructor
@NoArgsConstructor
@Data
public class Shoes {
    private String name;
    private int size;
    private Type type;

    @Override
    public String toString() {
        return ToStringBuilder.reflectionToString(this, ToStringStyle.MULTI_LINE_STYLE);
    }
}

/**
 * @author gavin
 */
public enum Type {
    WALKING,
    RUNNING,
    TRACKING,HIKING
}

@Test
public void enuTest(){
    Shoes shoes = new Shoes();
       shoes.setName("Nike");
       shoes.setSize(2400);
       shoes.setType(Type.HIKING);
       Assert.assertNull(shoes.toString());
   }

com.example.demo.demo.Shoes@332f25c8[

  name=Nike

  size=2400

  type=HIKING

]
