I added Spring Security Starter dependency (I use Maven) to secure my app (following a tutorial); the problem is that once I add it, whenever I go to localhost to check my progress, I'm always redirected to a path that's coded in another project (I can't even find the view right now).
I currently follow the tutorial on TutorialsPoint, but I use Spring Tools Suite 4 for adding dependencies, coding and running my Spring application instead of CLI on localhost:8080.
I tried finding the view in question, tinkering with another project's web.xml, but I can't find the source of the problem, all I know is that Spring Security Starter is somehow mucking it up.

The expected result from "localhost:8080" is just a header "Demo" (like in index.html and set in web controller), but instead a form I worked on before on another Spring project shows up with path "/login".
You need to override some of web security's default configurations if you want index.html to be accessed without authorization. taken from https://docs.spring.io/spring-security/site/docs/4.2.5.RELEASE/apidocs/org/springframework/security/config/annotation/web/configuration/EnableWebSecurity.html
#Configuration
#EnableWebSecurity
public class MyWebSecurityConfiguration extends WebSecurityConfigurerAdapter {
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/", "/index").permitAll().anyRequest()
.permitAll();
}

I have made projects before on spring and never got any issue like this before ,i just can't seem to figure out what is wrong here, all dependencies are correctly imported .
Here is how my vaultengine.java looks like :
VaultEngine.java :
package com.example.VaultEngine;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#SpringBootApplication
#Controller
public class VaultEngineApplication {
public static void main(String[] args) {
SpringApplication.run(VaultEngineApplication.class, args);
}
#GetMapping("/h")
public String greetingForm() {
return "index.html";
}
}
I am using a custom port cause i have 8080 in use somewhere already.
application.properties:
server.port=8989
All dependencies are properly loaded.

You are using spring-boot-starter-thymeleaf, so
#GetMapping("/h")
public String greetingForm() {
return "index";
}
and put index.html to src/main/resources/templates/.
refs:
https://spring.io/guides/gs/serving-web-content/

https://docs.spring.io/spring/docs/5.2.7.RELEASE/spring-framework-reference/web.html#mvc-controller
Use #RestController instead of #Controller
#SpringBootApplication
#RestController
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
#GetMapping("/h")
public String greetingForm() {

I tried to setup Spring boot basic example in my machine. BUt after setup, i am getting 404 status code returned.
I tried so many solutions provided on stack overflow. But none of them resolved my problem. Please help me, TIA.
I tried sub package structure to main mathod present package.
I tried adding scanBasePackages to #SpringBootApplication. Still no luck.
my code: Main Class . I tried by using without and with scanBasePackages.
package com.online.sbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication(scanBasePackages = {"com.online.sbo"})
public class OnlineSboApplication {
public static void main(String[] args) {
SpringApplication.run(OnlineSboApplication.class, args);
}
}
My controller: In server logs its not showing that this controller is registerd.
package com.online.sbo;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.ResponseBody;

Application.properties:- There is No entry in this file.
You use #RestController attribute wrong.
This should work:
#RestController
#RequestMapping("/home")
public class HomeController {
#GetMapping(value="/render", produces =
MediaType.APPLICATION_JSON_VALUE)
#ResponseBody
public String renderHomre() {
return "gfvbytfgh";
}
}
ps: In your example localhost:8080/render should work, too.
I'm trying to do a sample with Spring Cloud Gateway for JWT authentication and URL routing purpose.
All is running well when i run as a JAVA application or using Embedded Tomcat Container but when the same is deployed to a Tomcat server as a War, then i ge the below dependency injection error.
APPLICATION FAILED TO START
Description:
Parameter 4 of method routeDefinitionRouteLocator in org.springframework.cloud.gateway.config.GatewayAutoConfiguration required a bean of type 'org.springframework.core.convert.ConversionService' that could not be found.
The injection point has the following annotations:
- #org.springframework.beans.factory.annotation.Qualifier(value=webFluxConversionService)
Action:
Consider defining a bean of type 'org.springframework.core.convert.ConversionService' in your configuration.
I have tried adding jars related to spring web flux but the error did not go

Spring Cloud Gateway does not support WAR deployments. It is based on Spring Webflux and Spring Boot does not support war deployments of webflux.
From the documentation:
Because Spring WebFlux does not strictly depend on the Servlet API and
applications are deployed by default on an embedded Reactor Netty
server, War deployment is not supported for WebFlux applications.

There are a few things wrong with your demo project.
1. Incorrect package structure
You put your Runner class to a default package. It not a good idea, because in this case Spring Boot is not able to set a default package for component scanning. When you run your application you should see something like:
** WARNING ** : Your ApplicationContext is unlikely to start due to a #ComponentScan of the default package.
Solution: move all your classes to common package.
2. spring-boot-starter-thymeleaf is missing
In your pom.xml file add following dependency to make Thymeleaf templates working:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
Then remove following dependency that is present in your pom.xml:
<!-- https://mvnrepository.com/artifact/org.thymeleaf/thymeleaf -->
<dependency>
<groupId>org.thymeleaf</groupId>
<artifactId>thymeleaf</artifactId>
<version>3.0.9.RELEASE</version>
</dependency>
3. spring.thymeleaf.mode=LEGACYHTML5 requires additional dependency
When you run your app and you open http://localhost:8080 you will see following exception:
org.thymeleaf.exceptions.ConfigurationException: Cannot perform conversion to XML from legacy HTML: The nekoHTML library is not in classpath. nekoHTML 1.9.15 or newer is required for processing templates in "LEGACYHTML5" mode [http://nekohtml.sourceforge.net]. Maven spec: "net.sourceforge.nekohtml::nekohtml::1.9.15". IMPORTANT: DO NOT use versions of nekoHTML older than 1.9.15.
at org.thymeleaf.templateparser.html.AbstractHtmlTemplateParser.parseTemplate(AbstractHtmlTemplateParser.java:90) ~[thymeleaf-2.1.6.RELEASE.jar:2.1.6.RELEASE]
at org.thymeleaf.TemplateRepository.getTemplate(TemplateRepository.java:278) ~[thymeleaf-2.1.6.RELEASE.jar:2.1.6.RELEASE]
at org.thymeleaf.TemplateEngine.process(TemplateEngine.java:1104) ~[thymeleaf-2.1.6.RELEASE.jar:2.1.6.RELEASE]
at org.thymeleaf.TemplateEngine.process(TemplateEngine.java:1060) ~[thymeleaf-2.1.6.RELEASE.jar:2.1.6.RELEASE]
at org.thymeleaf.TemplateEngine.process(TemplateEngine.java:1011) ~[thymeleaf-2.1.6.RELEASE.jar:2.1.6.RELEASE]
This is because you have specified:
spring.thymeleaf.mode=LEGACYHTML5
and you haven't add nekoHTML library to the classpath.
Solution: add following dependency to your pom.xml:
<dependency>
<groupId>net.sourceforge.nekohtml</groupId>
<artifactId>nekohtml</artifactId>
<version>1.9.22</version>
</dependency>
After applying all these steps you will see "Hello" on your app's home page. Hope it helps.
I am very new to Spring framework. I have created a new Spring Starter Project with following modules: web, mongo, security.
I have created a simple controller
#RestController
#RequestMapping("/users")
public class UserController {
private UserRepository userRepository;
#GetMapping("/all")
public List<User> getAllUsers(){
List<User> users = this.userRepository.findAll();
return users;
}
#PostMapping("/")
public void insert(#RequestBody User user){
this.userRepository.save(user);
}
}
And seeded some raw data to the database. When I make request to this route in Postman, I get the following response:
{
"timestamp": 1511113712858,
"status": 401,
"error": "Unauthorized",
"message": "Full authentication is required to access this resource",
"path": "/users/all"
}

What is causing the unauthorized response and how to disable it for the /all route? Thanks!
#Configuration
public class WebSecurityConfiguration extends WebSecurityConfigurerAdapter {
#Override
public void configure(HttpSecurity http) throws Exception {
http.requestMatchers().antMatchers("/users/all").permitAll();
}
}
You need to configure Spring Security, by default all routes all secured for authrorization.
The code above disables security only for "/users/all" URL.
I was getting this error as I included
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-oauth2-client</artifactId>
</dependency>
in my pom.xml file.
Just remove it and try again.
You can keep your security dependency but then you have to setup a userid and a password. This can be done by adding the following into your application.properties file located under
src/main/resources
folder
security.user.name=user # Default user name.
security.user.password= # your password here
