Trae是由字节跳动（ByteDance）推出的一款AI 原生集成开发环境（IDE），简单来说，它是一款专为程序员打造的、深度集成了人工智能的“写代码神器”。
你可以把它理解为一个“能自己写代码、修 Bug 的智能编程助手”。它基于 VS Code 的内核开发的，因此如果习惯用 VS Code，上手 Trae 会非常顺滑。
1.安装
官网：
https://www.trae.cn/
下载：
下载后的文件：
直接双击安装即可。
2.界面介绍
进入trae，可以看到去界面布局和VsCode非常相似，所以我们主要是学习右边的ai相关的知识。
1.ctrl+u可以快速调出侧边栏，如果选中了代码ctrl+u，会把选中的代码提问词里。
2.@符号可以选择模式
chat模式类似于你问我答的形式，比如之前的腾讯元宝，deepseek等
Builder模式可以根据需求描述直接在目录里生成代码文件。
不管是chat模式还是Builder模式，界面是一致的。
3.上下文引用
直接粘贴和使用 # 引用在技术原理、效率和准确度上有着本质的区别。#引用这通常不计入你的“对话记忆”限制（或者占用极少）
4.上传图片，语音输入，多模态。
3.Builder模式基本演示
chat模式主要是根据我们输入的提示词做出回答，而Builder模式可以根据需求描述直接在目录里生成代码文件。
新建一个springboot项目，生成一个HelloController方法，我访问hello返回字符串Hello，你好。
点击新建项目：
生成了四个文件，这里选择全部保留：
这里配置了jdk
查看HelloController：
package com.example.demo.controller; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; @RestController public class HelloController { @GetMapping("/hello") public String hello() { return "Hello, 你好"; } }启动类：
package com.example.demo; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; @SpringBootApplication public class DemoApplication { public static void main(String[] args) { SpringApplication.run(DemoApplication.class, args); System.out.println("Hello, 你好"); } }依赖：

可以在项目的settings.json里上设置,添加userSettings配置，使用D盘下的仓库。
{ "redhat.telemetry.enabled": true, "workbench.colorTheme": "Deep Blue", "maven.executable.options": "", // 添加下面的配置。 "java.configuration.maven.userSettings": "D:\\software\\java\\maven\\apache-maven-3.6.3\\conf\\settings.xml" }但是这样只在此项目里生效，打开新项目一样存在问题，所以可以在全局配置文件里修改：
比如我这里全局配置文件的地址是：C:\Users\29531\AppData\Roaming\Trae CN\User
再次右击启动：
启动成功！
浏览器访问也正常。
我们也可以直接使用mvn的命令启动项目：
我们可以在终端里通过下面命令启动springboot项目：
D:\software\java\maven\apache-maven-3.6.3\bin\mvn.cmd spring-boot:run可以启动成功，但是每次输出这么长的地址太麻烦了，添加配置：
{ "redhat.telemetry.enabled": true, "workbench.colorTheme": "Deep Blue", "maven.executable.options": "", // 添加下面的命令 "terminal.integrated.env.windows": { "Path": "D:\\software\\java\\maven\\apache-maven-3.6.3\\bin;C:\\Windows;C:\\Windows\\System32;C:\\Windows\\System32\\WindowsPowerShell\\v1.0;C:\\Program Files\\dotnet;D:\\software\\java\\jdk\\jdk-17.0.7\\bin;C:\\Users\\29531\\AppData\\Local\\Microsoft\\WindowsApps;D:\\software\\java\\nodejs;C:\\Users\\29531\\AppData\\Local\\Programs\\Microsoft VS Code\\bin" }, "java.configuration.maven.userSettings": "D:\\software\\java\\maven\\apache-maven-3.6.3\\conf\\settings.xml" }这样只需要在终端输入下面命令即可运行springBoot:
maven spring-boot:run
