Apache工具类ToStringBuilder用法简介

ToStringBuilder比较适合在打日志时，输出参数的信息，特别是在参数为对象时，该工具类能够很方便的自动打印对象中的属性值。 

 package test;

 /**
  *
  * @author zhengtian
  * @time 2012-6-28
  */
 public class User {
     private String name;
     private int age;

     public String getName() {
         return name;
     }

     public void setName(String name) {
         this.name = name;
     }

     public int getAge() {
         return age;
     }

     public void setAge(int age) {
         this.age = age;
     }

 }

下面是ToStringBuilder的使用方法 

 System.out.println("-------------ToStringBuilder-------------------------");
 User u = new User();
             u.setAge(25);
             u.setName("zhengtian");

             //对象及其属性一行显示
             System.out.println(ToStringBuilder.reflectionToString(u));
             System.out.println(ToStringBuilder.reflectionToString(u, ToStringStyle.DEFAULT_STYLE));
             //属性换行显示
             System.out.println(ToStringBuilder.reflectionToString(u, ToStringStyle.MULTI_LINE_STYLE));
             //不显示属性名，只显示属性值，在同一行显示
             System.out.println(ToStringBuilder.reflectionToString(u, ToStringStyle.NO_FIELD_NAMES_STYLE));
             //对象名称简写
             System.out.println(ToStringBuilder.reflectionToString(u, ToStringStyle.SHORT_PREFIX_STYLE));
             //只显示属性
             System.out.println(ToStringBuilder.reflectionToString(u, ToStringStyle.SIMPLE_STYLE));

结果显示： 
-------------ToStringBuilder------------------------- 
test.User@141d683[name=zhengtian,age=25] 
test.User@141d683[name=zhengtian,age=25] 
test.User@141d683[ 
  name=zhengtian 
  age=25 
] 
test.User@141d683[zhengtian,25] 
User[name=zhengtian,age=25] 
zhengtian,25
