I'm using latest Spring Boot (1.2.7.RELEASE). I would like to use the #CrossOrigin annotation from the package org.springframework.web.bind.annotation as described in CORS Support section in Spring docs.
I'd think I already have all the necessary dependencies (via Spring Boot defaults), but this is confusing: CrossOrigin is not found, even though stuff like RestController from the same package works!
Error:(8, 47) java: cannot find symbol
symbol: class CrossOrigin
location: package org.springframework.web.bind.annotation
What's going on? Has CrossOrigin been removed from later versions of Spring-MVC, or am I missing some dependency?
pom.xml:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.2.7.RELEASE</version>
</parent>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
Alright, looks like the latest Spring Boot release, 1.2.7.RELEASE at the moment, is too old to have a version of Spring MVC with CrossOrigin. (Spring Boot 1.2.7 uses Spring version 4.1.8).
I updated to latest Spring Boot 1.3 release candidate (1.3.0.RC1) and it works:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.0.RC1</version>
</parent>
Also needed to specify spring-milestones repository in pom.xml to be able to use the non-release version.
<repositories>
<repository>
<id>spring-milestones</id>
<url>http://repo.spring.io/milestone</url>
</repository>
</repositories>
Update: override Spring version
As Stéphane Nicoll pointed out, a simpler way to get Spring 4.2.2 classes (such as CrossOrigin) into use is this:
<properties>
<!-- ... -->
<spring.version>4.2.2.RELEASE</spring.version>
</properties>
#CrossOrigin annotation is used to provide support for cross domains,
ie nothing but from different domains also we can access that service
by default it is true.
we can access the services from cross domains also.

Using a fresh Spring Initialzr with Java17 and Spring Boot 3.0.0, and an extra addition to the pom.xml for Springfox Swagger 3, I can't for the life of me get Swagger pages to work. Instead, I get the whitelabel error page with 404.

The standard Swagger URLs as defined in this Github Issues page aren't working for the above pom.xml project.
I had given up and went to use Spring Boot 2.7 after posting the question. But, after seeing Dmitriy's answer though, I checked Springdoc one last time and found that Springdoc v2 does support Spring Boot 3.
Essentially, one has to place the following in their pom:
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
<version>2.0.0</version>
</dependency>
Then one can access the Swagger page using the following URL: http://localhost:8080/swagger-ui.html (Don't forget to add context path if you need it). For some reason, when opening, it redirects to http://localhost:8080/swagger-ui/index.html although going for that initially returned 404...
in addition to adding springdoc-openapi-starter-webmvc-ui (v2.0.2 for me) as indicated in the accepted answer, I also needed to remove org.springdoc:springdoc-openapi-ui:1.6.13 .
It was there because I had tried it before. If present, there's still a non Jakarta reference that Spring tries to resolve (and fails to do so).
I also needed to add this dependency, otherwise I would have a nasty message at startup (version is resolved by Spring Boot BOM) :
implementation group: 'org.hibernate.validator', name: 'hibernate-validator'
Lastest
springfox-boot-starter version 3.0.0
and
springdoc-openapi-ui 1.6.13
seems not to support spring-boot 3.
We need to wait until the new version adopts jakarta.servlet package
Springdoc is working with Spring boot 3.0.1
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
<version>2.0.2</version>
</dependency>
Default URL: http://localhost:8080/swagger-ui/index.html
For Gradle you can add this:
implementation 'org.springdoc:springdoc-openapi-starter-webmvc-ui:2.0.0'
I agreed with #Ahmed Tawfik because I also faced the same. But today I tried that same approach with the new version of "springdoc-openapi-starter-webmvc-ui" dependency and Spring Boot 3.0.2-SNAPSHOT.
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
<version>2.0.2</version>
</dependency>
because the previous one "springdoc-openapi-ui" is changed to the above one.
Also, include below the path to the security config for swagger UI.
"/v3/api-docs/**","/swagger-ui/**"
For my project,
#Bean
public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
return http.cors(AbstractHttpConfigurer::disable)
.csrf(AbstractHttpConfigurer::disable)
.exceptionHandling(exceptionHandlingConfigurer -> exceptionHandlingConfigurer.authenticationEntryPoint(unauthorizedHandler))
.authorizeHttpRequests(authorizationManagerRequestMatcherRegistry -> {
try {
authorizationManagerRequestMatcherRegistry
.requestMatchers(HttpMethod.POST, POST_AUTH_WHITELIST).permitAll()
.requestMatchers(HttpMethod.GET, GET_AUTH_WHITELIST).permitAll()
.requestMatchers("/v3/api-docs/**", "/swagger-ui/**").permitAll()
.anyRequest()
.authenticated()
.and()
.sessionManagement(session -> session.sessionCreationPolicy(SessionCreationPolicy.STATELESS));
} catch (Exception e) {
throw new ResourceNotFoundException(e.getMessage());
}
}
)
.formLogin(AbstractHttpConfigurer::disable)
.httpBasic(AbstractHttpConfigurer::disable).addFilterBefore(jwtAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class)
.authenticationProvider(daoAuthenticationProvider()).build();
}
The swagger UI link will be:
http://server:port/context-path/swagger-ui.html
Please adjust the server, port, and context-path regarding your personal changes.
All the above steps are working fine with my project. I don't need extra configuration.
Also, you can add the custom path (Optional):
springdoc.swagger-ui.path=/swagger-ui.html
Here is the Official Documentation of OpenApi 3 and Spring Boot : https://springdoc.org/v2/#features
In the above documentation, you can explore additional configurations and other things also.
Happy Learning! ✌️
Use Open API instead swagger for Spring v3.0. Follow this document Open API Docs

Updated: Attached pom.xml and application.property and some more error / warning msgs.
Hi I am very new to Spring Boot and just taking some classes on Udemy for it.
While following through a class, I create a starter project via spring.io and added actuator and Hal browser dependencies including Dev tools.
Just ran my app and tried to go to localhost:8080/application & /browser as well but I get 404.
What am I doing wrong?
I wrote a simple bean which returns a hard coded value and then print that, I changed the value to test Dev tools and it didn’t restart the resource , I had to kill and restart the app to reflect the new changes ..
How can I check what the issue ?
I can provide console grab if needed.
Please help.
Update: I don't know the significance of the following so putting it in here.
in the XML editor hal is red underlined with the following msg on hover:
The managed version is 3.0.5.RELEASE The artifact is managed in org.springframework.data:spring-data-releasetrain:Kay-SR5
in the XML editor devtools is red underlined with the following msg on hover:
The managed version is 2.0.0.RELEASE The artifact is managed in org.springframework.boot:spring-boot-dependencies:2.0.0.RELEASE

application.properties file:
logging.level.org.springframework = DEBUG
management.security.enabled=false
Note: This answer is based on Spring Boot 2 (paths and properties have changed from version 1).
Your pom.xml looks fine to me. To get the "HAL Browser" to work with actuator you should have starters: web, actuator, and Rest Repositories HAL Browser. I recommend Spring Initializr as a nice way to construct an initial valid project structure.
The default path for the actuator is /actuator. Health, for example, is at /actuator/health.
To view the actuator endpoints in the HAL Browser, go to /browser/index.html#/actuator.
You can change the actuator path in application.properties by setting the following.
management.endpoints.web.base-path=/actuator
To run your server, use the following console command:
./mvnw clean spring-boot:run
If you have DevTools in your project, then changes to files in your classpath will restart the server. See my further comments on how to take advantage of DevTools here.
Here's the relevant documentation on a single page for easy searching:
https://docs.spring.io/spring-boot/docs/2.0.0.RELEASE/reference/htmlsingle
https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle
Add this Dependency:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-rest-hal-browser</artifactId>
<version>3.3.5.RELEASE</version>
</dependency>`enter code here`
And then go to link:
http://localhost:8080/browser/index.html#
Spring Boot 2.2 apps should use spring-data-rest-hal-explorer rather than spring-data-rest-hal-browser
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-rest-hal-explorer</artifactId>
</dependency>
For enabling actuator, add this into the property file (application.properties)
management.endpoints.web.exposure.include=*
Restart the Spring boot application and access the actuator endpoints using:
http://localhost:8080/actuator/
the health of the application can also be monitored using:
http://localhost:8080/actuator/health
dependency required:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-actuator</artifactId>
</dependency>
Ain't you were studying a course by "in28minutes"? =) Anyway when I studied on a Spring Boot for Beginners in 10 Steps course, I faced the same issue with accessing http://localhost:8080/application.
For http://localhost:8080/browser I got a plain json:
{"cause":null,"message":"Fragment must not be empty"}
In pom.xml I had the same dependencies as you outlined in question.
Some googling brought me to this article. In section named "II. Hal Browser" you can see a screenshot, where in browser a link is http://localhost:8080/browser/index.html#. If use this link, then Hal Browser should magically appear.
So /index.html# was the only puzzle piece you missed.
Note: above approach worked with Spring Boot version 2.1.7
EDIT: despite the fact that Hal Browser itself works with above approach, it still doesn't show actuator endpoints. And DevTools also ain't working for me.
It is really great to grab the Spring Kafka 2.1.0.RELEASE to unleash the power of the kafka client 1.0.0. However when I tried to use it spring boot 1.5.9.RELEASE , which is the latest release version of boot it throws an exception .

How should I be able to use Spring Kafka 2.1.0.RELEASE with a spring boot project .
Is there any release of boot that support spring 5 yet.
Thanks

This is beautifully explained by Francisco , I put up the link as it might help others as well!
I am using Spring boot 1.5.9.RELEASE and spring-kafka:2.1.0.RELEASE have faced similar but not this exception, I would suggest cleaning and building application again to clear maven cache and dependencies.
I'm having the following problem:
I am trying to setup a basic Spring Boot (2.0.0.M2) Project containing Spring Webflux and Spring Security.
My pom.xml looks like this (generated via start.spring.io):
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.0.M2</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<dependencies>
...
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-webflux</artifactId>
</dependency>
...
</dependencies>
SpringSecurityConfig:
#EnableWebFluxSecurity
public class SecurityConfig extends WebFluxSecurityConfiguration {}
I am not getting any further because I get an exception on startup:
Caused by: java.lang.ClassNotFoundException: org.springframework.security.web.server.context.SecurityContextRepository
So I figure that the whole org.springframework.security.web.server package is not on the classpath, although it should be there, since it is included in the API docs.
Seems like I am doing something wrong, but I don't know what.
Currently Spring Boot's spring-boot-starter-security does not include spring-security-webflux.
Add it as project dependency explicitly.
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-webflux</artifactId>
</dependency>
See this issue : Provide auto-configuration for WebFlux-based security.
BTW, check my working codes: https://github.com/hantsy/spring-reactive-sample/tree/master/boot
Updated: In Spring Boot 2.0.0.RELEASE, spring-boot-starter-security includes webflux support.
It seems when I add the dependency for the spring-hateoas
<groupId>org.springframework.hateoas</groupId>
<artifactId>spring-hateoas</artifactId>
<version>0.13.0.RELEASE</version>
The Class below is no longer available on the classpath
org.springframework.web.bind.annotation.RestController;
I have tried to exclude various dependencies for the spring-hateoas but the APP no longer runs.
Has anyone had any luck running spring-hateoas within spring boot.
Absolutely no problem whatsoever. The #RestController annotation is still available and you shouldn't need to do any exclusion.
In case it helps, I'm currently using version 1.0.2 of Spring Boot:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.0.2.RELEASE</version>
</parent>
spring-boot-starter-web provides the #RestController:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
I don't define an explicit version for spring-hateoas in my pom.xml, but my build is pulling in 0.9.0.RELEASE:
<dependency>
<groupId>org.springframework.hateoas</groupId>
<artifactId>spring-hateoas</artifactId>
</dependency>
As a side note, I can see from the Eclipse POM editor, that Spring HATEOAS is defining dependencies on Spring 3.2.7. However the spring-boot-starter-parent project manages the versions up to 4.0.3. Can you see what version of Spring you are getting? Have you perhaps not used the spring-boot-parent as a parent project?
