I have an existing Spring app that is a web application and I'm trying to add a REST API to it.
I'm not sure how to connect everything so it works
I've added an entry to web.xml. Originally the servlet class was pointed to my DispatcherServlet that I created, but I pointed it to org.springframework.web.servlet.DispatcherServlet based things I found online.
web.xml
<servlet>
<servlet-name>rest</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>rest</servlet-name>
<url-pattern>/rest/*</url-pattern>
</servlet-mapping>
rest-servlet.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd">
<context:component-scan base-package="com.company.platform.rest" />
<mvc:annotation-driven />
</beans>
Class:
package com.company.platform.rest;
import java.util.concurrent.atomic.AtomicLong;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/rest")
public class RestDispatcherServlet {
private static final String template = "Hello, %s!";
private final AtomicLong counter = new AtomicLong();
@GetMapping("/service/greeting")
public GreetingTest greeting(@RequestParam(value = "name", defaultValue = "World") String name) {
return new GreetingTest(counter.incrementAndGet(), String.format(template, name));
}
}
any help to point me in the right direction would be appreciated

A copy past from a project :
web.xml
<servlet>
<servlet-name>rest-api</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>

The answer to this is there was a filter active, so the /rest/ entrypoint needed to be added to it like this:
<filter>
<filter-name>SomeFilter</filter-name>
<filter-class>com.SomeFilter</filter-class>
<init-param>
<param-name>entryPoints</param-name>
<param-value>/someform.form,
/somejavascript.js
/rest/*
</param-value>
</init-param>
</filter>
