JSP file not rendered in Spring Boot application

JSP file not rendered in Spring Boot application - java

I have a Spring Boot web application that reads index.jsp and uses tomcat jasper to support JSP. However, the page is showing up as "There was an unexpected error (type=Not Found, status=404)." I suspect either the issue lies with the dependency.

The method runs as the print statement executes

Add this dependency with other ( like web ) in your pom file.

In application.properties file add this config properties for file location (Your .jsp file location in class path)
Properties config:
spring.mvc.view.prefix = /WEB-INF/views/
spring.mvc.view.suffix =.jsp
spring.mvc.static-path-pattern=/resources/**
OR
Class level config:
#Configuration
#EnableWebMvc
#ComponentScan(basePackages= {"com.imran"})
public class WebConfig implements WebMvcConfigurer {
public void configureViewResolvers(ViewResolverRegistry registry) {
registry.jsp().prefix("/WEB-INF/views/").suffix(".jsp");
}
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
}
and your controller will be like this (with out .jsp extension, just file name):
#Controller
public class indexController {
#RequestMapping(value = "/index", method = RequestMethod.GET)
public String getIndex() {
System.out.println("test1");
return "index";

How to fix 404 Error when deploying SpringBoot App to AWS Elastic Beanstalk?

I'm trying to deploy a very basic Spring Boot web app to AWS Elastic Beanstalk, It works fine locally, but each time I try to run it on elastic beanstalk I get a 404 error.
Here is my Controller:
package com.example.springhelloworld;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
#Controller
public class HelloWorldController {
#RequestMapping("/")
public String returnHello(){
return "helloworld";
}
}
Here is my main class:
package com.example.springhelloworld;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
#SpringBootApplication
public class SpringHelloWorldApplication extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(SpringHelloWorldApplication.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(SpringHelloWorldApplication.class);
}
}
Here is my html template:

I see two issues.
You need to add this dependency to your pom file
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
/src/main/resources/static is meant to hold static files such as html and css
Create directory src/webapp/WEB-INF/jsp
Move your jsp into the above directory
Update prefix spring.mvc.view.prefix=/WEB-INF/jsp/
https://hellokoding.com/spring-boot-hello-world-example-with-jsp/

Put samples.jsp in "resources/templates"

You muste enable the mvc configuration. Create a class config :
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
#EnableWebMvc
#Configuration
public class Config {
}

Repeatedly getting WhiteLabel error page w/ Mapping specification

I'm new to Spring. I am currently following a tutorial to the T and ran into the "Whitelabel error page". I've done my research, checking Spring boot - Whitelabel Error Page and Spring Boot Remove Whitelabel Error Page with no luck.
I am trying to reach the page by simply using : http://localhost:8080/hello
Obviously Spring cannot find the page, but I cannot figure out why that is.

Any help is appreciated
EDIT:
answer I was looking is found here - Issue With Spring: There was an unexpected error (type=Not Found, status=404)
Add component scanning for packages that are not in the same package, or in sub-packages, of the main class.

you have to configure viewResolver and internalResourceView Resolvers to serve jsp/html files find the below code snippet go through the link
package com.howtodoinjava.app.controller;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;
#Configuration
#EnableWebMvc
#ComponentScan
public class MvcConfiguration extends WebMvcConfigurerAdapter
{
#Override
public void configureViewResolvers(ViewResolverRegistry registry) {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/view/");
resolver.setSuffix(".jsp");
resolver.setViewClass(JstlView.class);
registry.viewResolver(resolver);
}
}

I can not use freemarker when i am building my spring boot's web project

My request can get into my method of my Welcomecontroller,but it semms that this method can not return a freemarker page to me or spring boot didn't distinguish freemarker(I have put .ftl files into /resources/templates/)
When I input the url http://localhost:8080/index
I got this from my chrome and don't report any errors in my IDEA's console:
Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

As of Spring Boot 2.2 the suffix for Freemarker templates is ftlh not ftl.
This is documented in the Release Notes.
Rename your welcome.ftl to welcome.ftlh and it will work with the default configuration.

Add this to application.yml
server:
servlet:
context-path: /cx
and then try http://localhost:8080/cx/index
Make sure you put .ftl files into /resources/templates/
P.S.
You don't need this dependency, as it is already included in spring-boot-starter-web:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>

Spring with maven, jar packaging, not displaying welcome.jsp page

Hi I am using Spring boot with maven jar packaging. My project structure looks like this
I am starting my project from command promt with this command:
mvn package && java -jar target/ProjekatNekretnine-0.0.1.jar, and it starts perfect. Than I go to http://127.0.0.1:8080/api/users/home and I do not get my welcome.jsp page. My controller class looks like this:
UserController class:
package com.projekat.nekretnine.controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import com.projekat.nekretnine.Model.Korisnik;
#RestController
#RequestMapping(value="api/users")
public class UserController {
#RequestMapping(value = "/home")
public String welcome(Model model) {
return "welcome";
}
}
I think that my welcome method should return my welcome.jsp file, but instead it writes "welcome" to the page. Why is that so? What am I doing wrong?
My welcome.jsp file looks like this:
<!DOCTYPE HTML>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Getting Started: Serving Web Content</title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
</head>
<body>
<h1>This is working.</h1>
</body>
</html>
So you see that it shouldn't write welcome.

One more thing, when I created maven project, I selected that the packaging should be JAR, not WAR. I don't know if I need now web.xml or other xml files, I think not. Maybe the mistake is where I put my static files, if that's the problem, can you tell me where to put tham?
And I tried to use #Controller, instead of #RestController in my UserController class, and still the same problem.
Thank you in advance.

The behaviour your are experiencing is normal.
This happens because you instructed your controller( specifically your rest-controller ) to return a String object when it hits /api/users/home endpoint.
If you however want to expose a page(view) in this endpoint you should configure your spring-boot to use a InternalResourceViewResolver.
You could take a look at a similar question Configure ViewResolver with Spring Boot and annotations gives No mapping found for HTTP request with URI error. and apply the changes for your controller to return the welcome page.
