2、为什么要使用ToStringBuilder？...使用ToStringBuilder就可以避免暴内存这种问题的。...二、示例学习 1、ToStringBuilder的append方法 ToStringBuilder类主要用于类的格式化输出。...ToStringBuilder中append方法可以向该类添加基本类型、数组、和对象，只有添加的方法才会被toString输出。...ToStringBuilder： 当你需要重载 toString 函数而不想写代码把当前类的所有成员信息列出来，可以用这个函数。
日常开发中，经常用org.apache.commons.lang3.builder.ToStringBuilder工具类来记录日志，比如： package com.cnblogs.yjmyzz; import...org.apache.commons.lang3.builder.ToStringBuilder; import org.apache.commons.lang3.builder.ToStringStyle...obj = new DemoObject(); //原始toString() System.out.println(obj); //ToStringBuilder...的输出(默认风格） System.out.println(ToStringBuilder.reflectionToString(obj)); //ToStringBuilder...的输出(短前缀风格） System.out.println(ToStringBuilder.reflectionToString(obj, ToStringStyle.SHORT_PREFIX_STYLE
javaBean的属性名不一样，导致接收不到： Child类用来接收传过来的json串： packagecom.test.dto;importorg.apache.commons.lang3.builder.ToStringBuilder...voidsetChileFather(String chileFather) {this.chileFather =chileFather; } @OverridepublicString toString() {return ToStringBuilder.reflectionToString...packagecom.test.dto;importcom.fasterxml.jackson.annotation.JsonProperty;importorg.apache.commons.lang3.builder.ToStringBuilder...voidsetChileFather(String chileFather) {this.chileFather =chileFather; } @OverridepublicString toString() {return ToStringBuilder.reflectionToString...packagecom.test.dto;importcom.alibaba.fastjson.annotation.JSONField;importorg.apache.commons.lang3.builder.ToStringBuilder

此外，这些IDE们提供了许多方式来生成我们自己的toString：字符串连接（使用+号）、StringBuffer、StringBuilder、ToStringBuilder（Commons Lang...平均操作次数/秒 用’+'连接字符串 142.075,167 String builder 141.463,438 Objects.toString 140.791,365 Guava 110.111,808 ToStringBuilder...(append) 75.165,552 ToStringBuilder (reflectionToString) 34.930,630 ReflectionToStringBuilder 23.204,479

此外，IDE为我们提供了几种选择来生成toString： String级联（使用+符号），StringBuffer，StringBuilder，ToStringBuilder，ReflectionToStringBuilder...如你所看的结果，内部更易于使用，代码行更少，但会对性能造成严重影响： public String toString() { return new ToStringBuilder(this...// (min, avg, max) = ( 73510,509, 75165,552, 76406,370) public String toString() { return ToStringBuilder.reflectionToString
