Spring Boot - REST Controllers

Examine the following Spring Boot POST method. What is the main issue that would prevent it from correctly receiving the item value from the request body?

@PostMapping("/addItem")
public String addItem(String item) {
    return "Item added: " + item;
}

AThe method parameter lacks the @RequestBody annotation to bind the request body.

BThe method should return void instead of String.

CThe @PostMapping annotation should specify consumes = "application/xml".

DThe method name must be addItemPost to handle POST requests.

Step-by-Step Solution

Solution:

Step 1: Understand parameter binding
To bind the HTTP request body to a method parameter, @RequestBody is required.
Step 2: Analyze the method
The parameter 'String item' lacks @RequestBody, so Spring won't map the POST request body to it.
Step 3: Evaluate other options
Return type String is valid; consumes attribute is optional; method name does not affect mapping.
Final Answer:
Option A -> Option A
Quick Check:
Missing @RequestBody causes binding failure [OK]

Quick Trick: Add @RequestBody to bind POST request body [OK]

Common Mistakes:

Forgetting @RequestBody on method parameters
Assuming method name affects HTTP method mapping
Misunderstanding return type requirements
