Java 工具类 ToStringBuilder

 System.out.println("-------------ToStringBuilder-------------------------");

    User u = new User();

    u.setAge(25);

    u.setName("wangsan");

    

  //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@15[name=wangsan,age=25]

test.User@15[name=wangsan,age=25]

test.User@15[

  name=wangsan

  age=25

]

test.User@15[wangsan,25]

User[name=wangsan,age=25]

wangsan,25

//toStringBuilder比较适合在打印日志时，输出参数信息，特别是在参数为对象的时，该工具类能够很方便的自动打印对象的属性值。

logger.info("getUserInfo response : {}",
  new Object[] { ToStringBuilder.reflectionToString(res,ToStringStyle.MULTI_LINE_STYLE) });
