利用ReflectionToStringBuilder打印VO里的属性

有时候我们要在log里把VO里面的一些属性打印出来，一般我们都会去改写类的toString方法，apache的ReflectionToStringBuilder类利用放射机制，能方便的实现类的toString方法，还能通过参数设置toString的样式

 

import org.apache.commons.lang.builder.ReflectionToStringBuilder;
import org.apache.commons.lang.builder.ToStringStyle;

public class UserVO {
	private String name;
	private String password;
	private int age;
	private String gender;
	
	Setter and Getter
	
	/* (non-Javadoc)
	 * @see java.lang.Object#toString()
	 */
	/*@Override
	public String toString() {
		return ReflectionToStringBuilder.toString(this, ToStringStyle.SIMPLE_STYLE);
	}*/
	
}

 

 

public class Test {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		UserVO vo = new UserVO("zhangsan","123",8,"male");
		//String s = ReflectionToStringBuilder.toString(vo, ToStringStyle.MULTI_LINE_STYLE);
		//ToStringStyle.SIMPLE_STYLE 设置toString显示样式
		ReflectionToStringBuilder.setDefaultStyle(ToStringStyle.MULTI_LINE_STYLE);
		String s = ReflectionToStringBuilder.toStringExclude(vo, "password");//将password属性排出在toString方法之外
		System.out.println(s);
	}

}
