Spring Boot Echo Example

A small app that echoes back a nice JSON with some info from the incoming requests:

• Request protocol
• Request method
• Request headers
• Request cookies
• Request params (query string)
• Request path
• Request body (Base64 encoded)

Is is usefull to trace/debug problems while developing REST APIs and SOAP WebServices.

Features:

1. Spring Boot 1.3.7, supporting fully executable JARs for Linux based operating systems, including “service” support
2. Accepts HTTP methods: GET, POST, PUT, DELETE and OPTIONS
3. Accepts all content type (*/*)
4. Catches everything (ie, mapped at /**), thus no webjars, no favicon.ico and no /error
5. Response code is always a 404 "Not Found" to avoid unexpected client behavior
6. GZip compression is disabled (on purpose) to avoid unexpected client behavior
7. Response content type is always "application/json;charset=UTF-8".
8. Only 1 class, about 50 lines of code!!!
9. Small. Final JAR includes everything (it self-contained) and it is only 12 MB

To get the code:

Try it using your browser, REST client, SoapUI, with:

• http://localhost:8080/sample.asp?product=42&category=dummy
• http://localhost:8080/sample.php?name=john
• http://localhost:8080/sample.html
• http://localhost:8080/sample.json
• http://localhost:8080/sample.css
• http://localhost:8080/sample.js
• http://localhost:8080/ws/sample.wsdl
• http://localhost:8080/people/1/cars

Use your preferred IDE such as SpringSource Tool Suite (STS) or IDEA:
