无法让我的项目类使用Spring框架

Question

这是我试图导入springframework的类:

package API;
import Class.Flight;
//import org.springframework.web.bind.annotation.*;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class FlightController {
@PostMapping("/flight")
public String addFlight(@RequestBody Flight flight) {
// Do something with the flight data, such as saving it to a database
return "Flight information received!";
}
}

这是我的pom.xml文件:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

我是新手，一直在疯狂地编辑依赖项。在stackoverflow上读了一些东西。我设法修复了依赖关系和maven错误，但我无法弄清楚我的Flight.java类有什么问题。它不会导入spring框架，因此我不能使用RestController、PostMapping和RequestBody。我一直得到错误:

package org.springframework.web.bind.annotation不存在

package org.springframework.web.bind.annotation不存在

package org.springframework.web.bind.annotation不存在

看起来你的pom.xml文件是一个非结构化的格式

您可以从Spring Boot Initializr中创建Spring Boot项目。

您可以访问下面的页面来创建Spring Boot项目:
