spring-session-jdbc timeout handler - jdbc

I am using Spring Session Jdbc for session management and need to do some custom operations on session Timeout listener. How should I do this? I tried to use HttpSessionListener, but this doesn't work, it only works if I'm not using spring-Session. Spring-session-core is version 2.6.1

nested exception is java.lang.NoClassDefFoundError: org/springframework/web/context/request/async/StandardServletAsyncWebRequest

I'm working on a standard spring app (i.e. not a spring boot app) and the version of spring is 4.2.13.RELEASE.
I'm trying to use StreamingResponseBody which I have done many times, but on this occasion I am getting this error:
nested exception is java.lang.NoClassDefFoundError: org/springframework/web/context/request/async/StandardServletAsyncWebRequest
Anyone know what's going on here?
If you are working with spring boot, you must include this maven dependency:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
This is the spring boot parent that I'm using in my project:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.6.RELEASE</version>
<relativePath/>
</parent>
For non spring boot applications you can use the next dependency in your pom:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-web</artifactId>
<version>5.3.0</version>
</dependency>
This config may solve your exception.

Spring-boot(maven) actuator,devtools not working

I'm a newbie to spring-boot. Trying to create a simple web application using spring-boot maven. Basic static page display using dependency spring-boot-starter-web worked fine. When I included spring-boot-devtools and spring-boot-starter-actuator in pom.xml it is giving build error Re-run Maven using the -X switch to enable full debug logging.
I tried including spring-webmvc dependency in pom file, still the result is same.

I downloaded this project from spring.io (SPRING INITIALIZR website). Build project is getting failed.
<scope>runtime</scope> of spring-boot-devtools suppose not to be runtime. In fact according to the doc -
Developer tools are automatically disabled when running a fully
packaged application. If your application is launched from java -jar
or if it is started from a special classloader, then it is considered
a “production application”. Flagging the dependency as optional in
Maven or using a customdevelopmentOnly configuration in Gradle (as
shown above) is a best practice that prevents devtools from being
transitively applied to other modules that use your project.
So, change the dependency as below -
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-devtools</artifactId>
<optional>true</optional>
</dependency>
you can update your pom.xml and change the version number to any previous stable version.It worked for me.

How to verify a Spring feature/Bug fix is available in the Spring boot version which i am using?

I am working on a spring batch program to process data from sql and write to an xml. I used staxEventItemWriter to do that. But due to this issue https://jira.spring.io/browse/BATCH-1377 i am not able to fix the namespace issue. When we look at comments on this Jira card it says its fixed in 2010. But its not available in the latest spring boot versions which i am using. i tried with the patch class described in the Jira card its working fine for me.

How to verify a Spring feature/Bug fix is available in the Spring boot version which i am using?
You are using Spring Boot 2.0.4.RELEASE. This will bring Spring Batch version 4.0.1.RELEASE. You can find more details about dependencies using the Spring Boot Initializr REST API.
The issue BATCH-1377 is marked as resolved in version 2.1.0.RC1 and is also available in 4.0.1.RELEASE.
But its not available in the latest spring boot versions which i am using. i tried with the patch class described in the Jira card its working fine for me.
The patch suggested by the contributor uses an additional property rootTagNamePrefix but this was modified as per this comment to use the naming convention {uri}prefix:root in order to be consistent with Spring WS. The issue was fixed here: https://github.com/spring-projects/spring-batch/commit/f56ee747296961917caa38fa9e14785dafc0b18b
So in your case, you need to use this naming convention if you want to add a namespace to the root tag. See example here: https://github.com/spring-projects/spring-batch/blob/f56ee747296961917caa38fa9e14785dafc0b18b/spring-batch-infrastructure/src/test/java/org/springframework/batch/item/xml/StaxEventItemWriterTests.java#L287

Why class SecurityEvaluationContextExtension can not be found in Spring Boot Project?

I have a spring boot based project with following declaration in pom.xml:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.3.2.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
and following dependencies among others
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-rest</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
But seems like spring boot is not pulling in SecurityEvaluationContextExtension class on the classpath.
Am I missing a dependency or am I using an older version of spring boot?
EDIT:
I directly added the following dependency in my pom.xml and now I can see the class, but STS is showing warning : "Duplicating managed version 4.0.3.RELEASE for spring-security-data"
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-data</artifactId>
<version>4.0.3.RELEASE</version>
</dependency>
I am not shure what you mean with 'spring is not pulling in..'
But to use this extension you have to create a bean of this type see
SecurityEvaluationContextExtension
EDIT :
The warning you are getting is no problem. You can try removing the version from the dependency, because it seems available through dependencyManagement.
