[Java] API creation using Jerjey (Jax-rs) in eclipse


There weren't many ways to implement it without using maven or gradle, so I'll write it.

Introduction of Jerjey

Creating a project

Create a dynamic web project in Eclipse Create a package [com.sample.api] and a class [SampleApi.java] under it.

Creating web.xml

Create [web.xml] in WebContent / WEB-INF and copy the following.


<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns="http://java.sun.com/xml/ns/j2ee"

    <param-value>com.api.sample</param-value><!--package name-->




Editing ApiSample.java

Edit the first created ApiSample.java below.


package com.api.sample;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.QueryParam;
import javax.ws.rs.core.MediaType;

public class ApiSample {
	@Produces(MediaType.TEXT_HTML + "; charset=UTF-8")
	public String hello(@QueryParam("name") final String name){
		return "Hello!"+name+"Mr.";



Results Hello! Null.

Is displayed, it is OK. Also, http: // localhost: 8080 / project name / api / Sample / hello? name = Yamada If you enter

Hello! Mr. Yamada.

Should be displayed.
