Getting started with myeclipse development rest Service

• Step 1: create a web service project;
• Step 2: Create a class

Myeclipse supports the rest service, which is very convenient for development. Here is an example of a computer:

Functions: addition, subtraction, multiplication, and Division;

The effect is as follows:



Key points of the rest service: each service or anything has a URI;

Step 1: create a web service project; Step 2: Create a class

The difference between rest and RPC.

• Rest emphasizes that resources have unique Uris, while RPC is more powerful (verb) and is called by unified interfaces.
• Rest regression was originally designed for HTTP. RPC only uses HTTP as the transmission protocol.
• Rest is driven by hypertext; RPC is driven by methods.
• Rest emphasizes the semantic visibility of HTTP Communication, which is embodied by the message header and standard HTTP method. RPC encapsulates the semantics in the HTTP message body.
