trying to load this webpage.
index.html
<html>
<body>
<p>Get your greetinghere</p>
</body>
</html>
However all that is returned is the text, index.html is not being displayed by the web browser, i added all the dependencies I thought i would need. The tomcat server runs fine and there is no warnings anywhere to indicate I need to add something.


Your browser is not displaying it as a html document, because it doesn't recognize it as such. Please read about the HTML5 standard and it's minimal requirements, eg. here

Spring Boot returns Error 404 even though mapping has been set

I downloaded a Spring Boot project from Spring Initializr. I am trying to call sayHello() method in DemoApplication.java. Here are my code.

System.out.println("started");
SpringApplication.run(DemoApplication.class, args);
System.out.println("Success");
}
#GetMapping("/hello")
public String sayHello(#RequestParam(value = "myName", defaultValue = "World") String name) {
return String.format("Hello %s!", name);

When I run on http://localhost:8080/hello it returns error 404 page. It does not call sayHello() method even though I have set the GET mapping. What could be the issue?

The problem is your dependencies, or rather the lack of them.
You included spring-web as a dependency but that isn't enough to launch your web app. You would also need to add spring-webmvc and as you want to use REST (and probably JSON) you would need to add the jackson-databind dependency (and if you want to support dates also the jackson-datatype-jdk8 dependency).
Now you could of course manually figure all this out yourself by trial and error. Or you just include the spring-boot-starter-web which automatically includes (compatible) versions of all of those dependencies (including Embedded Tomcat).
So in short fix your dependencies.
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
This should be all you need, if you build a WAR instead of JAR you might want to add
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
This will make tomcat provided and moved out of the lib folder but still your app would be runnable for development (through the main method) and deployable as a war (without tomcat being in the lib directory).

I cant start my spring boot project, error 404 when i run

This is my controller which should open the index page
#Controller
public class index {
#RequestMapping("/index")
public String index() {

I will not display the html page because is too long

Тhese are the project directories
When I run my project browser show me 'HTTP Status 404 – Not Found' and I read other post but i dont find fix, help me guys
I try to with this 2 links
http://localhost:8080/cinemaweb or
http://localhost:8080/index

Use #RestController instead of #Controller
#RestController
public class index
{
#GetMapping("/index")
public String index()
{
return "index";
}
}

Better use the #RestController instead of #Controller
then #GetMapping(value = "/index") on the method - instead of #RequestMapping
then the url is: http://localhost:8080/index

If you want to return a String as an Object, then use #RestController or #ResonseBody annotaion, like this
#Controller
public class MainController {
#RequestMapping(value = "/", method = RequestMethod.GET)
public #ResponseBody String get() {
return "index";
}
}
Also I highly reccomend you to replace spring-web dependecy for spring-boot-starter-web, I
mean this
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
Than Spring boot will take care about all required beans, e.g. dispatcher servlet etc.

HTTP Status 404 for Spring Web REST API after deploying dynamic application to Tomcat server on Eclipse

I've got a fresh Spring Web application from https://start.spring.io/ with a few dependecies.
Whenever I try to access a REST controller path ("api/companies") the server sends a 404 result with the following message:
"The origin server did not find a current representation for the
target resource or is not willing to disclose that one exists.".
Here's my pom.xml:

This is how the project structure looks like:
The application's entry point is the CompaniesApplication class:
package helium.erp.com.companies;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
#SpringBootApplication
public class CompaniesApplication extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(CompaniesApplication.class, args);
}
}
The REST controller I'm trying to reach is the following:
package helium.erp.com.companies.company;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
#RequestMapping("/api/companies")
public class CompanyApi {
#GetMapping(value = "")
public ResponseEntity<String> getAllCompanies() {
return ResponseEntity.ok("all companies");
}
}
I put a single html file at the root in WebContent and is perfectly returned when I send a GET to the "localhost:9091". The project is added as a server resource and here is the server's configuration:
I have changed the project context root from the default "companies" to "/" via the Eclipse project settings > web project settings > context root and changed the path via the server modules settings like so:
What am I doing wrong? Is there some configuration I am missing?

[SOLVED] Fixing the deployment assembly paths in Eclipse resolved the issue.

Try to add spring boot parent pom. With it you shouldn't specify starters versions - parent pom contains all information about needed versions.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.1.RELEASE</version>
</parent>

From what I can see your problem is the way you're importing the dependencies, the recommended way to do so is by using the Spring Boot's parent pom and its managed dependencies.
I recommend you to use start.spring.io to generate your next projects, here's a sample with the Spring Boot dependencies that you have, the major diff is the parent pom.
For your project, you need to add the extra dependencies such as oracle and any further configuration you have.

Try use this pom.xml
It was generated by https://start.spring.io/ and I inserted your Oracle dependencies and repositories.

When you face NoSuchMethodException at runtime, it generally means 'classpath hell' - e.g., for simplification, when you've got two version of the same library (one containing the method, but the other - not) and only god knows which version will actually get into your final build if you don't do anything.
To find such dependencies, you shoult run 'mvn dependency:tree' command and search for something related to 'org.springframework.boot.devtools'... => most probably you'll see two versions
Then - you should either use section of maven POM to strictly set the version, or, as guys suggested above - use spring boot parent (also, a more advanced solution is importing a BOM - which is kind of a set of rules for dependency versions).

Error in rendering jsp page using Spring boot?

I am trying to render a jsp page from my controller but I find this strange thing happening. When I run the application, it displays the actual html code of the page instead of displaying the view. This is quite strange what could I be doing wrong. So,it basically the whole html code of the welcome page is being displayed when I run my application.
package com.example.DemoService;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.Map;
#Controller
public class HelloController {
#RequestMapping("/test")
public String welcome(Map<String, Object> model) {
model.put("message", "Raaj");
return "welcome";
}
}
Jsp
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<html>
<body>
Hello ${message}
</body>
</html>

You have multiple things that you need to do:
add in your application.properties this (presuming you have your jsp in src/webapp/WEB-INF/jsp)
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
Try putting tomcat-embed-jasper with <scope>compile</scope>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>compile</scope>
</dependency>
There seems to be a bug, at least in IntelliJ, if you run it with <scope>provided</scope> it will not recognize the jsps. If you run with maven (mvn spring-boot:run) it runs fine regardless of the scope
