ToStringBuilder+ToStringStyle的用法

package com.java.etl.codeTest;

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

public class Test {
 public static void main(String[] args) {
  Test t = new Test();
  String z = t.toString();
  System.out.println(z);
 }
 
 
 public String toString() {
        return new ToStringBuilder(this, ToStringStyle.MULTI_LINE_STYLE)
                .append("name", "a")
                .append("age", "b")
                .toString();
    }

}

运行结果：

com.java.etl.codeTest.Test@173a10f[
  name=a
  age=b
]
