자바빈(javaBean) 의 값을 보다 쉽게 확인하는 util

1. 자바빈 생성

public class BoardBean {
  private String name;
  private String title;
  public String getName() {
    return name;
  }
  public void setName(String name) {
    this.name = name;
  }
  public String getTitle() {
    return title;
  }
  public void setTitle(String title) {
    this.title = title;
  }
}

2. 확인

public class BeanTest {
 
 
  public static void main(String[] args) {
    BoardBean board = new BoardBean();
    board.setName("jsp");
    board.setTitle("javaproject");
     
    try {
      System.out.println( BeanUtils.getBeanGetValue(board));
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}

3. 출력
name = jsp
title = javaproject
class = class BoardBean
