Spring工具类ToStringBuilder用法简介

比如说我们需要打印某个方法的User参数对象

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

描述：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。
