Step-by-Step Solution
Solution:
Step 1: Understand how to map same path with different methods
Spring allows multiple methods mapped to the same path but different HTTP methods using method attribute.Step 2: Evaluate options
Use two methods with @RequestMapping(path = "/items", method = RequestMethod.GET) and @RequestMapping(path = "/items", method = RequestMethod.POST). correctly uses two methods with same path but different HTTP methods. Use one method with @RequestMapping(path = "/items") and check HTTP method inside the method manually. is less clean and error-prone. Use @RequestMapping(path = "/items") on both methods without specifying method attribute. causes ambiguity. Use @RequestMapping(method = RequestMethod.GET) on one method and @RequestMapping(method = RequestMethod.POST) on the other without path. misses path, so won't map correctly.Final Answer:
Use two methods with @RequestMapping(path = "/items", method = RequestMethod.GET) and @RequestMapping(path = "/items", method = RequestMethod.POST). -> Option AQuick Check:
Separate methods with same path, different HTTP methods [OK]
Quick Trick: Map same path with different methods by specifying method attribute [OK]
Common Mistakes:
- Not specifying method attribute causing conflicts
- Checking HTTP method manually inside one method
- Omitting path attribute causing mapping errors
