Spring MVC RestController 404 The requested resource is not available

I am trying to write a simple 'hello world' application using Spring MVC.
My goal is to send a GET response and receive a text message, however it keeps returning 404 "The requested resource [/api/hello] is not available". What can potentially be wrong? Below is my code:
package org.example.rest.controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
#RequestMapping("/api")
public class MyRestController {
#GetMapping("/hello")
public String hello() {
return "Hello";
}
}

I am using IntelliJ IDEA 2022.2.2 (Ultimate Edition).
Server is Tomcat 9.0.71

Basic Spring based WSSecurity client gets a null response

I've been following this tutorial to learn how to develop a basic spring client and server application using wssecurity (certificates).
The demo works beautifully, but i need to deploy my application on a wildfly server, so i had to change the example a bit in order to avoid the embedded tomcat, the changes are as follows:

#ResponsePayload
public GetBeerResponse getBeer(#RequestPayload GetBeerRequest request) {
GetBeerResponse beerResponse = new GetBeerResponse();
Beer beer = new Beer();
beer.setId(request.getId());
beer.setName("Beer name");
beerResponse.setBeer(beer);
return beerResponse;
}
}
I deployed the server application on my wildfly and i tried to call it using the same client application used in the tutorial. The service seems to answer correctly, the beerResponse object is correctly istantiated, but, as soon as the object is being sent back to the the client, i see it's NULL.
What am i missing?
Thanks in advance

Oh well, next time i'll read better. At the same link of my first post, a guy asked the same question in the comments, here is the solution: add a callBackHandler to the client configuration, and modify the securityInterceptor to use this handler.
SoapClientConfig.java
package com.memorynotfound.client;
import org.springframework.boot.web.server.WebServerFactoryCustomizer;
import org.springframework.boot.web.servlet.server.ConfigurableServletWebServerFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.ClassPathResource;
import org.springframework.oxm.jaxb.Jaxb2Marshaller;
import org.springframework.stereotype.Component;
import org.springframework.ws.client.support.interceptor.ClientInterceptor;
import org.springframework.ws.soap.security.wss4j2.Wss4jSecurityInterceptor;
import org.springframework.ws.soap.security.wss4j2.callback.KeyStoreCallbackHandler;
import org.springframework.ws.soap.security.wss4j2.support.CryptoFactoryBean;
import java.io.IOException;
#Configuration
public class SoapClientConfig {
#Bean
public Wss4jSecurityInterceptor securityInterceptor() throws Exception {
Wss4jSecurityInterceptor securityInterceptor = new Wss4jSecurityInterceptor();
// set security actions
securityInterceptor.setSecurementActions("Timestamp Signature Encrypt");
// sign the request
securityInterceptor.setSecurementUsername("client");
securityInterceptor.setSecurementPassword("changeit");
securityInterceptor.setSecurementSignatureCrypto(getCryptoFactoryBean().getObject());
// encrypt the request
securityInterceptor.setSecurementEncryptionUser("server-public");
securityInterceptor.setSecurementEncryptionCrypto(getCryptoFactoryBean().getObject());
securityInterceptor.setSecurementEncryptionParts("{Content}{http://memorynotfound.com/beer}getBeerRequest");
// sign the response
securityInterceptor.setValidationActions("Signature Encrypt");
securityInterceptor.setValidationSignatureCrypto(getCryptoFactoryBean().getObject());
securityInterceptor.setValidationDecryptionCrypto(getCryptoFactoryBean().getObject());
securityInterceptor.setValidationCallbackHandler(securityCallbackHandler());
return securityInterceptor;
}
#Bean
public CryptoFactoryBean getCryptoFactoryBean() throws IOException {
CryptoFactoryBean cryptoFactoryBean = new CryptoFactoryBean();
cryptoFactoryBean.setKeyStorePassword("changeit");
cryptoFactoryBean.setKeyStoreLocation(new ClassPathResource("client.jks"));
return cryptoFactoryBean;
}
#Bean
public Jaxb2Marshaller getMarshaller(){
Jaxb2Marshaller marshaller = new Jaxb2Marshaller();
marshaller.setContextPath("com.memorynotfound.beer");
return marshaller;
}
#Bean
public BeerClient getBeerClient() throws Exception {
BeerClient beerClient = new BeerClient();
beerClient.setMarshaller(getMarshaller());
beerClient.setUnmarshaller(getMarshaller());
beerClient.setDefaultUri("http://localhost:8080/ws/beers");
ClientInterceptor[] interceptors = new ClientInterceptor[]{securityInterceptor()};
beerClient.setInterceptors(interceptors);
return beerClient;
}
#Bean
public KeyStoreCallbackHandler securityCallbackHandler(){
KeyStoreCallbackHandler callbackHandler = new KeyStoreCallbackHandler();
callbackHandler.setPrivateKeyPassword("changeit");
return callbackHandler;

Issues with Spring Boot and Thymeleaf

Here are my configuration classes::
In the templateResolver() method without ServletContext parameter i get compile error so add it as a parameter and give it to ServletContextTemplateResolver(servletContext);
#Configuration
#EnableWebMvc
#ComponentScan(basePackages= {"com.packtpub.springsecurity"})
public class ThymeleafConfig {
#Bean
public ServletContextTemplateResolver templateResolver(ServletContext servletContext) {
ServletContextTemplateResolver resolver = new ServletContextTemplateResolver(servletContext);
resolver.setPrefix("/WEB-INF/templates/");
resolver.setSuffix(".html");
resolver.setTemplateMode("HTML5");
resolver.setCacheable(false);
resolver.setOrder(1);
return resolver;
}
#Bean
public SpringTemplateEngine templateEngine(final ServletContextTemplateResolver templateResolver) {
SpringTemplateEngine engine = new SpringTemplateEngine();
engine.setTemplateResolver(templateResolver);
return engine;
}
#Bean
public ThymeleafViewResolver thymeleafViewResolver(final SpringTemplateEngine templateEngine) {
ThymeleafViewResolver resolver = new ThymeleafViewResolver();
resolver.setTemplateEngine(templateEngine);
return resolver;
}
}
When i run my application i get following error:::
***************************
APPLICATION FAILED TO START
***************************
Description:
Parameter 0 of method templateResolver in com.packtpub.springsecurity.web.configuration.ThymeleafConfig required a bean of type 'javax.servlet.ServletContext' that could not be found.
The injection point has the following annotations:
- #org.springframework.beans.factory.annotation.Autowired(required=true)
Action:
Consider defining a bean of type 'javax.servlet.ServletContext' in your configuration.
What am i doing wrong?
thanks

What else can i do again

After some debugging on your code, the real problem is that you are autowiring ThymeleafViewResolver in the configuration responsible to configure servlet context.
public class WebMvcConfig implements WebMvcConfigurer{
#Autowired
private ThymeleafViewResolver thymeleafViewResolver;
The main problem is that before initializing your ServletContext, the application will try to initialize the ServletContextTemplateResolver (autowired will impose bean order initialization) and as you've noticed it depends on ServletContext.
Solution :
delete ThymeleafConfig class
don't autowire ThymeleafViewResolver in WebMvcConfig
and don't override method configureViewResolvers.
Don't worry, Thymeleaf will be set by default as the viewResolver.
Most of the config you've provided is already "taken care" by spring-boot-starter-thymeleaf.
If you want just to change default view directory resolver, you can just add in application.properties
spring.mvc.view.prefix=/WEB-INF/templates/
spring.mvc.view.suffix=.html
P.S: Take extra care when you override default definition from spring starters, as you can see these types of bugs are not easy to find.

Swagger not working with Spring REST API

Hello i am trying to implement swagger with Spring REST, i am not using Spring Boot to create REST API's, i have used normal Spring REST API.
The problem when i run the application and if i navigate to this url
http://localhost:8080/spring-mvc-restfull-crud-example/swagger-ui.html
i am getting only the header of swagger-ui, there is nothing else. I am using Java config instead of XML config.

can you please anyone help me that what is wrong in this? is there anything that i need to add?

You have not defined Docket bean and neither you have used the #EnableSwagger2
The configuration of Swagger mainly centers around the Docket bean. Swagger 2 is enabled through the #EnableSwagger2 annotation. Refer the below code.
#Configuration
#EnableSwagger2
public class SwaggerConfig {
#Bean
public Docket customImplementation() {
return new Docket(DocumentationType.SWAGGER_2).pathMapping("/data").apiInfo(apiInfo());
}
private ApiInfo apiInfo() {
return new ApiInfo("ISW ADR Application",
"ADR or is another business line within the Issuer services business group."
+ "The primary functionalities of ADR are maintained within the DR system (mainframe) "
+ "Four main functionalities that are imported : "
+" 1) Dividend Announcements"
+ " 2) Depositary Service fees"
+ " 3) DR Fees"
+ " 4) DR Gross revenue.",
"ADR V2", "Terms of service", "xyz", "License of API", "API license URL");
}
}

You have not enabled swagger using #EnableSwagger2 and also have not returned a Docket Bean. Refer this.
#Configuration
#EnableSwagger2
public class SwaggerConfig {
#Bean
public Docket demoApi() {
return new Docket(DocumentationType.SWAGGER_2).select()
.apis(RequestHandlerSelectors.basePackage("com.example.demo"))
.paths(PathSelectors.regex("/person.*")).build();
}
}

How to register an object in jersey 2(ResourceConfig)

I want to register a class component(Object) in jersey not class reference.
I create a XYZResource class that be called by main() method and it be configured through jersey with DBI object. DAOService daoService has connection DBI connection and the getDetails() that execute query and return result.
I use IntelliJ IDE and run through Main Class com.example.Main
when i hit my url http://localhost:9000/resource/test than it through error
javax.servlet.ServletException: A MultiException has 1 exceptions. They are:
1. java.lang.NoSuchMethodException: Could not find a suitable constructor in com.example.AdminResource class.

You seem to have a lot of unnecessary stuff going on. You have two different configurations. Pick one. The problem is caused by the package scanning, which is picking up the resource and trying to register it.
Just get rid of the web.xml and MyApplication and just use the ResourceConfig you're currently using in the main class. Then you can register the servlet programmatically using Jersey's ServletContainer which is both a Filter and a HttpServlet. So you don't need the web.xml to configure Jersey as Filter. The ServletContainer is already a Filter
new SevletContainer(youResourceConfig);
I'm not too familiar with Tomcat embedded so I can't say how to register filters, but I'm sure a quick search will find you the answer. Just register the ServletContainer as a filter.
The jersey.config.servlet.filter.forwardOn404 init-param can also be configured with the filter registration. Or you can just configure it with the ResourceConfig, with its property method
resourceConfig.property("jersey.config.servlet.filter.forwardOn404", true);
Or better yet, use the constant
property(ServletProperties.FILTER_FORWARD_ON_404, true);
UPDATE
Here is a complete setup (based on your example) that works.

A few changes I made:
Not sure why you are using Tomcat 7 Servlet API. I Changed that to the 8.x version of your other Tomcat dependencies.
I also excluded the Servlet API from the Jersey MVC dependency, as that pulls in an older 2.4 Servlet API
<dependency>
<groupId>org.glassfish.jersey.ext</groupId>
<artifactId>jersey-mvc-jsp</artifactId>
<exclusions>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
</exclusion>
</exclusions>
</dependency>
I added a DefaultServlet to handle the pages. From testing (again I am not Tomcat expert), it seems this is required
With the example you should be able to GET
http://localhost:9000/api/tomcat

First, Thanks to peeskillet who solved my problem. I search on the net but I did not find the exact solution.
For better reference and understandability, I create a demo application on git-hub.
jersey-mvc-jsp-freemarker-with-embedded-tomcat
Application Used
Tomcat v8.x
Jersey v2.5.1
JSP
YML
Freemarker
HTML/Angular/JavaScript
final ResourceConfig config = new ResourceConfig()
.packages(Main.class.getPackage().getName())
.register(new Resource(new Core(), configuration)) // create instance of Resource and dynamically register
.register(JspMvcFeature.class) // register jspMVC
.register(FreemarkerMvcFeature.class) // register FreemarkerMVC
.property(ServletProperties.FILTER_FORWARD_ON_404, true);
return new ServletContainer(config);
