Spring Boot - Request and Response Handling

Consider this Spring Boot configuration snippet:

@Override
public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
    configurer.favorParameter(true)
              .parameterName("format")
              .defaultContentType(MediaType.APPLICATION_JSON)
              .mediaType("xml", MediaType.APPLICATION_XML)
              .mediaType("json", MediaType.APPLICATION_JSON);
}

What is the likely problem if a client requests /api/data?format=txt?

AThe server will throw an error due to unknown format

BThe server will respond with XML format

CThe server will respond with JSON as default

DThe server will ignore the format parameter and respond with plain text

Step-by-Step Solution

Solution:

Step 1: Analyze configured media types
Only 'json' and 'xml' are mapped to media types; 'txt' is not recognized.
Step 2: Check default content type behavior
If the parameter value is unknown, Spring Boot falls back to the default content type, which is JSON here.
Final Answer:
The server will respond with JSON as default -> Option C
Quick Check:
Unknown format uses default JSON [OK]

Quick Trick: Unknown format falls back to default content type [OK]

Common Mistakes:

Expecting an error for unknown format
Assuming XML is default
Thinking plain text is sent automatically
