im learning Spring security and created a config file to change the login from form to basic as a first step, however the config file doesn't do anything and no changes happen
here is the code in the config file:
package Security;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.web.SecurityFilterChain;
#Configuration
#EnableWebSecurity
public class securityConfiguration {
#Bean
public SecurityFilterChain configure(HttpSecurity Sec ) throws Exception {
Sec
.authorizeRequests()
.anyRequest()
.authenticated()
.and()
.httpBasic();
return Sec.build();}
}
and this is my POM.xml :

i suspected the problem might be spring not picking up the config file but the annotations did nothing to fix this.
I believe the issue might have to do with how you are organizing the packages. By default, Spring will look under the package of the main application or any sub-packages.
It's hard to be sure from the information provided in the question, but for instance, if your main application class is under the package com.example, and the security configuration class is under the package Security, it won't find it by default. Also, be sure to not use the default package (or "no package").
So the options are:
Add #ComponentScan annotation to the main class to indicate where to look: #ComponentScan("Security")
Move the security config class under the same package as the main class or a sub-package: com.example.security (recommended).
See Spring documentation for reference.
I also suggest that you use the standard naming and styling conventions for Java. (lower-case package names, lower-case method attributes, pascal-case class names). See Naming conventions for reference. It will not only look better and consistent with other code bases but will also make it compatible with many tools that follow convention over configuration, which is favored a lot in the Spring ecosystem.

I'm trying to run Vaadin app on azure and I constantly getting error 404. It's basic app with only 2 classes - from spring initializr and one my class.
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
#SpringBootApplication
public class WsbProjektZalApplication {
public static void main(String[] args) {
SpringApplication.run(WsbProjektZalApplication.class, args);

I'm trying to run this app with war artifacts on tomcat 9. Problems occur only with Vaadin, I can run this app locally without any problems. Can somebody help me and tell me where I'm making mistake?
Screen of error below.
enter image description here
Try to resolve the error by adding the following in $TOMCAT_HOME/conf/server.xml
To avoid memory leaks, Tomcat disables the loading of Java driver files by default.
<Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" driverManagerProtection="false" />
Also, if you're creating a spring boot application, add "SpringBootServletInitializer" to your main file, as seen in the code below. As without SpringBootServletInitializer, Tomcat will see it as a regular application rather than a Spring boot application.
#SpringBootApplication
public class DemoApplication extends *SpringBootServletInitializer*{
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(DemoApplication .class);
}
public static void main(String[] args) {
SpringApplication.run(DemoApplication .class, args);
}
}

I haven't used spring in a while, and I'm trying to get spring boot dev tools to perform hot reloading. I've imported the web and spring boot dependencies from start.spring.io project generator and made a uri for "/hello". I can run the project but changing the uri values doesn't hot reload and I don't believe that the hot reloading is working. From what I've found on searching the internet, the only necessary step is to add the hot reloading dependency in your pom file:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
<optional>true</optional>
</dependency>
My entire pom.xml file is as follows (generated from the start.spring.io website):
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

And my web uri file is as follows (works, but without hot reloading):
package com.java.java_app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
#SpringBootApplication
#RestController
public class JavaAppApplication {
public static void main(String[] args) {
SpringApplication.run(JavaAppApplication.class, args);
}
#GetMapping("/hello")
public String hello(#RequestParam(value = "name", defaultValue = "World") String name){
return String.format("Hello %s!", name);
}
}
This is as simple an application as I think it is possible to build, so I'm confused on what extra necessary step is needed to make hot reloading work. It does not appear to be documented say here (https://www.baeldung.com/spring-boot-devtools) other than to add the dependency. If it matters I'm running ubuntu 20.04.
EDIT:
I am running the application in the terminal on port :8080 and using vim to modify the uri file while the application is running. Since java has a lot of plugins for various IDEs someone suggested that it is worth mentioning that.
If you are not using an IDE you can use ./mvnw compile and the project will recompile while the editor is running.
... "on project Jwplusapp: An exception occurred while running. null"
Does anyone know why I cannot select "spring-boot:run" through maven without getting that error?
Ive tried renaming the database file also making sure parent versions were correct. i tried to check the pom.xml but i think i am just missing it. any help in regards to this error code would be greatly appreciated. yes i saw similar posts but they didnt seem to fix the problem for me.

I tried with your pom.xml and it worked for me. It fails with same error only when you have same port (8080 or whatever you are using in the application) has already been occupied.
Can you please check the availability of the port on which you are trying to run.(if its occupied try running on other port or kill the same).
Also can you please paste the complete error after "null" in the stacktrace.
Updated:
make sure you have following properties in your project
spring.jpa.hibernate.ddl-auto=update
spring.datasource.url=jdbc:mysql://${MYSQL_HOST:localhost}:3306/db_examplele
spring.datasource.username=springuser
spring.datasource.password=ThePassword
And try below configuration if you are using jpa
#Configuration
public class HibernateConfig {
#Bean
public HibernateJpaSessionFactoryBean sessionFactory(EntityManagerFactory emf) {
HibernateJpaSessionFactoryBean factory = new HibernateJpaSessionFactoryBean();
factory.setEntityManagerFactory(emf);
return factory;
}
}
Turns out the solution was not because of an error in my code but the solution was to Download MySQL Installer - MySQL
Here is the link to download
https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=2ahUKEwjEh8aMnbbnAhXKjVkKHSbQCSoQFjAAegQICxAC&url=https%3A%2F%2Fdev.mysql.com%2Fdownloads%2Finstaller%2F&usg=AOvVaw2HevAKGob4r4A7Rv_R2hy5
I figured this out when checking my services and noticing that MYSQL80 service was not displayed.(Checked Services, also Task manager -> Services)
This then installed MySQL80 Service which was missing from my device, This then allowed my "spring-boot:run" to process successfully and open up my fully functioning webpage while connected to the desired localhost 3306 and fully connect to root on MYSQL workbench.
I am beginner for spring boot. I initialized a new project and tried to run it but it does not work successfully. WHen I run this as spring boot application, it starts execution. In bottom compiler/status bar, it shows processing and retrying. it goes upto 10 times and throw the following error:
Failed to refresh live data from process xxxx

I had the same problem in STS, and tried different things to resolve it. The following dependency for spring actuator makes that problem disappear, but however the main point of spring actuator provides more features than this. To learn more, click https://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-features.html
The dependency should be added to your pom.xml file
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
I have faced the same problem but managed to solve it.
The controller class has to be in the "child package" relative to the TestApplication class.
In your case, your TanmayTestApplication class is in the package com.example.tanmay_test. Therefore, your DemoControler class must be inside the package com.example.tanmay_test.xxx.
**Note that xxx can be anything but extends from package com.example.tanmay_test. For example, package com.example.tanmay_test.web.
Hope this helps!
Add this line in your file application.properties (src/main/resources):
spring.devtools.livereload.enabled=true
Live data is collected with the help of Spring Actuator.
You need to include the following dependency in your pom.xml
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
See https://github.com/spring-projects/sts4/wiki/Live-Application-Information#application-requirements-for-spring-boot-projects for reference.
I was also facing same issue after adding Spring Actuator dependency, it resolved.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
after adding this in POM.xml, do maven build and run again.
It is simply saying that you didn't enable LiveReload.
This is non other then the Data Source error
To resolves this I disabled the auto-configuration of the DataSource. And, this will not affect auto-configuring any other beans.
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
I'm using VS Code and the thing that worked for me was adding a dev tool dependency.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<scope>runtime</scope>
<optional>true</optional>
</dependency>
Also, add spring.devtools.livereload.enabled=true in application.properties file so that server knows that it has to reload every time a change is made.
Thanks for this one.
I'm going through the JPA starter tutorial for spring boot am struggling.
I know the question has been asked sometimes here ('Field required a bean of type that could not be found.' error spring restful API using mongodb)
But those problems are a bit different from what I have.
Structure
java
|
helloWorld
|
web/ -- HelloWorldController
Application
Customer
CustomerRepository
ServletInitializer
As you can see all my packages related to JPA are on the same level as my Application file . According to the tutorial (https://spring.io/guides/gs/accessing-data-jpa/) this should work
My Application class
package helloWorld;
import org.springframework.beans.factory.annotation.Autowired;
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;
import org.springframework.context.annotation.ComponentScan;
#SpringBootApplication
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
#Autowired
CustomerRepository customerRepository;
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(Application.class);
}
}
CustomerRepository
package helloWorld;
import org.springframework.data.repository.CrudRepository;
import java.util.List;
public interface CustomerRepository extends CrudRepository<Customer, Long> {
List<Customer> findByLastName(String lastName);
}
When trying to use #Autowired I receive
***************************
APPLICATION FAILED TO START
***************************
Description:
Field customerRepository in helloWorld.Application required a bean of type 'helloWorld.CustomerRepository' that could not be found.
Action:
Consider defining a bean of type 'helloWorld.CustomerRepository' in your configuration.
Also, adding scanBasePackages={"helloWorld"}) to #SpringBootApplication does not help and from what I read it should also not be needed.

You are excluding the autoconfiguration of JPA repositories. Remove the line from application.properties to let Spring make CustomerRepository a bean and configure it.
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
In my case, I just forgot to add #Component to Impl class of interface!
These errors may be due to absence of one or more stereotype annotations.
I changed this Class Level Annotation from my Application Class.
From:
#SpringBootApplication(exclude = {DataSourceAutoConfiguration.class })
To:
#SpringBootApplication
Try Adding the #ComponentScan("package.path.to.your.repository") annotation above Application class.
- Just make sure your repository is in the the same package path that is written in #ComponentScan
#SpringBootApplication
#ComponentScan("helloworld")
public class Application extends SpringBootServletInitializer {
//your stuff
}
I had the same issue and everything was good except adding the below dependecies.
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-jpa</artifactId>
<version>2.4.2</version>
And, It worked for me
you need to add #Repository in repository
