Cannot resolve symbol 'EnableSwagger2' issue in Spring boot - java

I am new to Spring boot. I am trying to add swagger by using #EnableSwagger2 annotation by creating a separate file. When I try to use annotation #EnableSwagger2, I am getting error: Cannot resolve symbol 'EnableSwagger2'. I have tried adding different dependencies, but it is not working. Can someone please help in finding me the correct dependency

The version of spring-data-r2dbc that you are using isn't compatible with the versions of the other Spring Data modules that Spring Boot 2.3.x uses by default.
Spring Boot 2.3 has dependency management and a starter module for Spring Data R2DBC so you can align the versions by using the starter and removing the versions from your pom.
Replace the following three dependencies:
<dependency>
<groupId>org.springframework.data</groupId>
<artifactId>spring-data-r2dbc</artifactId>
<version>1.0.0.RELEASE</version>
</dependency>
<dependency>
<groupId>io.r2dbc</groupId>
<artifactId>r2dbc-spi</artifactId>
<version>0.8.0.RELEASE</version>
</dependency>
<dependency>
<groupId>io.r2dbc</groupId>
<artifactId>r2dbc-postgresql</artifactId>
<version>0.8.0.RELEASE</version>
</dependency>
With the following:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-r2dbc</artifactId>
</dependency>
<dependency>
<groupId>io.r2dbc</groupId>
<artifactId>r2dbc-postgresql</artifactId>
<scope>runtime</scope>
</dependency>
The spring-data-r2dbc and r2dbc-spi dependencies are both part of the spring-boot-starter-data-r2dbc dependency that replaces them. The versions are provided by the dependency management in spring-boot-starter-parent.
If you have a similar problem in the future using the Explore feature of https://start.spring.io can be useful for figuring out how your pom should look.

Make library comes from maven

Hello guys I clone one project from github This project in spring boot.
When I import all library ResponseEntity.ok dosn't see from right place. When I put over imported path in class I see it comes from wrong directory. But When I create new project there is comes from right place. I've got question How I can figure it out call from right place instead of coming from wrong place. Thank you guys in advance
#GetMapping(value = "get")
public ResponseEntity<List<BssClient>> get(){
// cardStatement.CardStatement()
List<BssClient> list = dataBase.findAllBssClient();
return ResponseEntity.ok(list);
}

The right place of class path is
This is from different classes and from different project.
The question How to make library comes from maven instead of coming from java library. After clone new project from github.

Spring boot multi-module properties not working

I know there is a number of questions on this platform similar to this one but so far no solution has solved my problem.
The project was working just fine until I decided to modularize it, my folder structure looks like this
Accounting - Parent
-> banking - Child
-> Commons - Child
-> Reports - Child
-> humaResourceManagement - Child
-> payRoll - Child
-> sales - Child
After creating the modules I noticed all the sudden my app could not locate application.properties in my parent project, the child projects as of now do not have .properties so I know very well it is not a clash, before this was working I did not even need to #PropertySource annotations, it just worked but now it does not, for it to work I need to specify the properties like
#PropertySources({
#PropertySource("file:src/main/resources/application.properties"),
})
I feel this is a horrible solution, also it seems other parts of the app are not able to access the same application.properties, my properties has the logging configs below
logging.level.org.springframework=DEBUG
logging.level.web=DEBUG
logging.level.org.hibernate=DEBUG
Before Spring boot could log only debug logs but now it is logging Info, warn etc.
Below are my pom files

Someone help me figure out why my application.properties has stopped being loaded all the sudden
In case of 'jar' packaging, by default JAR Plugin looks for 'src/main/resources' directory for the resources and bundled them along with code build (if not configured for custom resource directory etc).
But 'pom' packaging doesn't work this way so application.properties is not included in build if it is not specified with some annotation etc.
Either you can create one more module which can be child to parent pom and parent to rest of modules to share one application.properties across whole project or you can use maven-remote-resources-plugin to use a remote resource bundle

If you are under spring boot, jackson is added by default,
So the version you are adding manualy is probably conflicting with the one spring boot adds,
Try to delete the jackson dependencies from your pom
I'd like to write this to a different answer, since the stacktrace you provided lead me to a completely different path.
I see in your pom.xml that you use jackson-core:2.1.3 and jackson-databind:2.1.3 version, which is more than 7 years old at this point.
However, based in this list, the spring version you use expects the much newer 2.9.8 version. So probably, the method not found exception is because during runtime, spring gets a completely different version of the ObjectMapper class (source code here), which probably doesn't have the required addMixIn() method.
To fix this, since the parent of you pom.xml is set to the spring-boot-starter-parent, you can just delete the tag which sets the version of all of your dependencies starting with jackson and spring.
I quickly went through the original version of you pom.xml and cleaned it up a little, try replacing the content of your pom.xml with this:

Please take a look at this part of your pom.xml:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>2.1.3.RELEASE</version>
<type>pom</type>
<scope>provided</scope>
</dependency>
This was not meant to be in project.dependencies. It was mean to be in project.dependencyManagement.dependencies.
What is probably happening is that maven includes all the dependencies into your project on compile-time, but doesn't package them with your application.
In the meantime, you use a dependency that is available because of the part I highlighted, but the class is not available during runtime.
Please try to place the part I highlighted like this:
<project>
...
<dependencyManagement>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-dependencies</artifactId>
<version>2.1.3.RELEASE</version>
<type>import</type>
<scope>provided</scope>
</dependency>
</dependencies>
</dependencyManagement>
...
</project>
Also pay attention to the scope, which changed from provided to import.

No SpringExtension.class

I am trying to setup Spring Boot + JUnit5... So by tutorials I could get so pom.xml:

And tried to make a test:
ExtendWith(SpringExtension.class)
#SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT)
public class UserControllerTest {
#Test
public void register() {
}
}
But there is not the SpringExtension.class, I can't import it.
Error:(7, 13) java: cannot find symbol
symbol: class SpringExtension
How to fix my pom.xml or maybe can I use a some another class?
P.S. I'm a noobie in the Spring so my question may be stupid but I can't get how to resolve.
The problem is with the version of Spring Boot. You are providing 1.5.9.RELEASE, but that class is provided from Spring 5 (according to SpringExtension), so try to use newer version of Spring Boot like 2.0.0.BUILD-SNAPSHOT or another extension like that one.
Your spring-boot version 1.5.9.RELEASE will not support Junit 5. Please change the spring-boot version to spring-boot-starter-parent version 2.0.0.BUILD-SNAPSHOT
Add the below line to your pom.xml
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.0.BUILD-SNAPSHOT</version>
</parent>
I Had a similar issue and it turns out the jar file, located at ~/.m2/repository/org/springframework/spring-test/5.0.5.RELEASE/spring-test-5.0.5.RELEASE.jar was corrupt. I had to delete the jar and refresh pom.xml
