Spring Boot - REST Controllers

Which of the following is the correct syntax to map a GET request to the URL /hello using @GetMapping in Spring Boot?

A@GetMapping(path = "/hello") public String greet() { return "Hi"; }

B@GetMapping(/hello) public String greet() { return "Hi"; }

C@GetMapping('/hello') public String greet() { return "Hi"; }

D@GetMapping(path = hello) public String greet() { return "Hi"; }

Step-by-Step Solution

Solution:

Step 1: Check the correct use of @GetMapping syntax
@GetMapping requires the path to be a string, usually passed as path = "/url" or simply "/url".
Step 2: Identify correct string usage and syntax
@GetMapping(path = "/hello") public String greet() { return "Hi"; } uses @GetMapping(path = "/hello") which is correct. @GetMapping(/hello) public String greet() { return "Hi"; } misses quotes around /hello. @GetMapping('/hello') public String greet() { return "Hi"; } uses single quotes, invalid for Java string literal. @GetMapping(path = hello) public String greet() { return "Hi"; } misses quotes around hello.
Final Answer:
@GetMapping(path = "/hello") public String greet() { return "Hi"; } -> Option A
Quick Check:
Correct syntax needs quotes and path attribute [OK]

Quick Trick: Always use quotes around URL paths in @GetMapping [OK]
