对于使用 Maven 的 Spring 引导应用程序，所有页面都在 Postman 中给出 404 错误

Question

https://github.com/SREEJA-PALLA/SpringBootCoursesAPI/tree/master

I'm getting a 404 error in postman this is my project.

{ "timestamp": "2021-05-18T17:46:24.979+00:00", "status": 404, "error": "Not Found", "message": "", "path": "/topics" }

I checked the dependencies and also tried many ways but nothing seemed to work. Can someone please help? Thank you in advance.

Answer 1

You have annotated your main application class with

@ComponentScan({"com.delivery.request"})

But this package does not exist in your codebase. So Spring does not find the Controller that you want it to find. This is in the package com.example.courseData.topic .
