I've successfully got the example running from here using a SimpleBroker.
My config is set up like:
#Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/topic");
//registry.enableStompBrokerRelay("/queue/","/topic/").setRelayHost("localhost").setRelayPort(61614);
registry.setApplicationDestinationPrefixes("/app");
}
When I comment out the SimpleBroker and try to use the StompBroker I get the following error.
ERROR: org.springframework.web.servlet.DispatcherServlet - Context initialization failed
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'stompBrokerRelayMessageHandler' defined in class path resource [org/springframework/web/socket/config/annotation/DelegatingWebSocketMessageBrokerConfigurat ion.class]: Instantiation of bean failed; nested exception is org.springframework.beans.factory.BeanDefinitionStoreException: Factory method [public org.springframework.messaging.simp.broker.AbstractBrokerMessageHandler org.springframework.messaging.simp.config.AbstractMessageBrokerConfiguration.stompBrokerRelayMessageHandler()] threw exception; nested exception is java.lang.NoClassDefFoundError: reactor/tcp/encoding/Codec

Am I missing some resource so that it won't create the bean stompBrokerRelayMessageHandler?
Running this on Tomcat v7.0 inside of STS and using ActiveMQ for the message broker.
You need add this at pom.xml
<!-- Reactor -->
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
<version>1.0.0.RELEASE</version>
</dependency>
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-tcp</artifactId>
<version>1.0.0.RELEASE</version>
</dependency>
To get Reactor 2.0 working with my Spring 4.2+ environment, I've added the following dependencies:
<dependency>
<groupId>io.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
<version>2.0.5.RELEASE</version>
</dependency>
<dependency>
<groupId>io.projectreactor</groupId>
<artifactId>reactor-net</artifactId>
<version>2.0.5.RELEASE</version>
</dependency>
<dependency>
<groupId>io.projectreactor.spring</groupId>
<artifactId>reactor-spring-context</artifactId>
<version>2.0.5.RELEASE</version>
</dependency>
See https://spring.io/blog/2015/02/18/reactor-2-0-0-rc1-with-native-reactive-streams-support-now-available
Then netty was missing in my classpath, so I've added:
<dependency>
<groupId>io.netty</groupId>
<artifactId>netty-all</artifactId>
<version>4.0.31.Final</version>
</dependency>
Your stack trace indicates very clearly it is missing a class:
java.lang.NoClassDefFoundError: reactor/tcp/encoding/Codec
See How to read and understand the java stack trace? if you're not sure how to read it.
For any class not found problem, the most common solution is to include the corresponding jar into your classpath.
The simplest way to do this is go to http://search.maven.org and query the full class name that's missing, for example:
fc:reactor.tcp.encoding.Codec
This will tell you the class belong to reactor-tcp jar. You can either download the jar and manually add it to your classpath or simply paste the maven dependency xml to your pom file.
rsaez's answer is almost right, in my case at last.
I had to add this:
<!-- Reactor -->
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
<version>1.1.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-net</artifactId>
<version>1.1.6.RELEASE</version>
</dependency>
I ran into the same issue and this worked for me. I am using Spring 4.1.6
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
<version>1.1.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-net</artifactId>
<version>1.1.6.RELEASE</version>
</dependency>
<dependency>
<groupId>org.projectreactor</groupId>
<artifactId>reactor-tcp</artifactId>
<version>1.0.1.RELEASE</version>
</dependency>
i have made it by following Alex Bretet above,
yet only one change is the version
<dependency>
<groupId>io.projectreactor</groupId>
<artifactId>reactor-core</artifactId>
<version>2.0.8.RELEASE</version>
</dependency>
instead of 2.0.5
my app works on spring 4.3.18
If you are using spring boot you can just use the amqp and reactor-netty starters:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-amqp</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-reactor-netty</artifactId>
</dependency>

So far I have tried manipulating the redis.clients and spring-boot-starter-data-redis versions by decreasing and increasing it but always problems with initialization occur. Every single tutorial which I found doesn't contain configuration for the new Spring Boot application version. I Will be grateful for suggestions on how to manipulate the pom.xml version of redis.clients and spring-boot-starter-data-redis to make the application starts again.
spring-boot-starter-data-redis already includes jedis as a dependency so you shouldn't add it to your pom.xml with a version that might not be compatible with your spring-boot-starter-data-redis.
In the case of spring-boot-starter-data-redis version 2.5.0, it includes jedis version 3.6.3 but you override this with version 3.1.0, which might not be compatible with spring-boot-starter-data-redis version 2.5.0.
Always check the dependencies already included in the Spring Boot Starters because incompatibilities are exactly what they try to avoid.
Having said all that, I am not completely sure that this will solve the issue, but it is a good place to start.
Update 26/01/2022
The spring-boot-starter-data-redis dependency pom.xml includes the following dependency:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-redis</artifactId>
<version>2.5.1</version>
<scope>compile</scope>
</dependency>
This spring-data-redis dependency pom.xml already includes jedis version:
<properties>
(...)
<jedis>3.6.0</jedis>
(...)
</properties>
And the dependency itself:
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
<version>${jedis}</version>
<optional>true</optional>
</dependency>
This means that you should only add the dependency to your pom.xml but set no version so that the one set in spring-data-redis is used as follows:
<dependencies>
(...)
<!-- OTHER DEPENDENCIES -->
<dependency>
<groupId>redis.clients</groupId>
<artifactId>jedis</artifactId>
</dependency>
(...)
<!-- OTHER DEPENDENCIES -->
</dependencies>
Spent several hours, so posting for spring boot versions 2.7.3 to be helpful for others.
spring-boot-starter-data-redis uses lettuce by default instead of jedis client. You would have to exclude lettuce and include jedis instead.
implementation ('org.springframework.boot:spring-boot-starter-data-redis') {
exclude group: 'io.lettuce.lettuce-core'
}
implementation 'com.github.houbb:redis-client-jedis:0.0.3'```

Oddly when i'm deploying my war file in Tomcat 8 it work great !
Please, If there's any suggestion, do not hesitate.
Thank You !
PS :I'm working with JAVA 8
The Main Problem is that: for Spring boot 2 The minimum supported version of Tomcat is 8.5.
-See more ==> https://dzone.com/articles/spring-boot-20-new-features-infrastructure-changes
To work with Tomcat 7 we should downgrade Spring boot to 1.X (I don't recommend it)
-See more about Spring boot 1.X requirement for Servlet containers ==> https://docs.spring.io/spring-boot/docs/1.4.1.RELEASE/reference/html/getting-started-system-requirements.html
I'm trying to run a war file in a maven aplication.
Since I need the oauth2 b2c from azure I found this usefull code
I've never tried Spring before so I'm new about it
I tried to compile with mvn compile and JDK 1.7 as it says in github
but I got an error instead:
Cannot find symbol : Base64
Searching on internet I found it was supported by Jdk 1.8 + and by importing error so I did the import and that did the trick.
After that I did mvn package and it also did the package generating the war files and target folder.
I ran the war file java -jar azure-b2c-oauth2.war
But got this error:
Exception in thread "main" java.lang.RuntimeException: java.lang.reflect.InvocationTargetException

Any help would be apreciate thanks!
below Command is not correct to run.
java -jar azure-b2c-oauth2.war
This only works for jar based packaging, If you choose to package your application as a war file you should refer to your server and IDE documentation.
Refer : http://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-running-your-application.html
refer for server deployment: https://www.mkyong.com/spring-boot/spring-boot-deploy-war-file-to-tomcat/
OR
you can build package spring boot as jar using below ,
<?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"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<!-- ... -->
<packaging>jar</packaging>
<!-- ... -->
</project>
and then use java -jar azure-b2c-oauth2.jar
Your POM.xml says WAR, either change that to Jar or use this code as is and package war and then use a server such as tomcat to unpack and run it.
You can only run jar files with java -jar filename but since your POM is set to war package, you create .war file
I have problems with configuration of Swagger in my Spring Boot project.
I was following the basic instruction for this, and somehow it doesn's work.
Here it is:
pom.xml
<!--SWAGGER-->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.4.0</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.4.0</version>
</dependency>
Java Swagger Config:
#Configuration
#EnableSwagger2
public class SwaggerConfig {
#Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())
.build();
}
}
And i am getting this Exception:

In SpringMVC, if you want to use Swagger2,you need add '#EnableWebMvc' in you config class,like this:
#Configuration
#EnableSwagger2
#EnableWebMvc
public class Swagger2Config {
……
}
Fixed it with removing #Configuration annotation in SwaggerConfuguration class.
Only keep #EnableSwagger2 annotation
#EnableSwagger2
public class SwaggerConfiguration {
#Bean
public Docket api() {
return new Docket(DocumentationType.SWAGGER_2)
.select()
.apis(RequestHandlerSelectors.any())
.paths(PathSelectors.any())
.build();
}
}
P.S. My dependencies:
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.6.1</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.6.1</version>
<scope>compile</scope>
</dependency>
step 1: Remove the #Configuration in SwaggerConfig Class
step 2: put such code in /WEB-INF/jetty-dispatcher-servlet.xml
<mvc:resources mapping="swagger-ui.html" location="classpath:/META-INF/resources/"/>
<mvc:resources mapping="/webjars/**" location="classpath:/META-INF/resources/webjars/"/>
<!-- Include a swagger configuration-->
<bean name="swaggerConfig" class="com.exchangewalk.web.config.SwaggerConfig"/>
There are two contexts, the default spring context and the spring MVC context. If you're using the #configuration annotation, that gets picked up by the default spring context scanning which has no visibility of the RequestMappingHandlerMapping. That's why it's important that the SwaggerConfig is a bean defined in the MVC context.
For details, please refer: https://github.com/springfox/springfox/issues/462
I had this problem when in pom.xml were spring-boot both dependencies for webflux and web were added:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
spring-boot-starter-webflux generated problem in that case.
I used springfox:
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
<version>3.0.0</version>
</dependency>
For me it was enough to eliminate webflux dependency, which was added accidentally, but maybe for someone this info will be useful.
u need additional this dependency :
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
<version>3.0.0</version>
</dependency>
Removing #Configuration fixed my issue but swagger stopped working for obvious reason

What is this java.lang.NoSuchFieldError: NULL about? Have no issue with 3.0.5.
This means there is a version mismatch--most likely with spring classes. So make sure all your spring jars are 3.1.0. Especially spring-expression. (Also upgrade your JPA provider (hibernate?) if it doesn't work after fixing spring)
It may help you.
Upgrading from Spring 3.0.3.RELEASE results in: java.lang.NoSuchFieldError: USER_DECLARED_METHODS
Earlier I had like this
<dependencies>
<!-- Spring 3 dependencies -->
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>3.1.2.RELEASE</version>
</dependency>
...
</dependencies>
Then I added
<dependencies>
<!-- Spring 3 dependencies -->

<artifactId>spring-core</artifactId>
<version>3.1.2.RELEASE</version>
