Spring Cloud Function with AWS API Gateway and AWS Lambda - java

Using the handler org.springframework.cloud.function.adapter.aws.FunctionInvoker::handleRequest I'm receiving the following error when calling my API Gateway endpoint with the payload below. The function is found and it runs the business logic correctly until it returns and throws this NullPointerException:
Cannot invoke "java.util.Map.size()" because "m" is null: java.lang.NullPointerException

However, according to the documentation I should be using the handler org.springframework.cloud.function.adapter.aws.SpringBootApiGatewayRequestHandler::handleRequest but when I do so it does not find the function. I have set both FUNCTION_NAME and MAIN_CLASS environment variables to their respective values.

This is the documentation I'm working from: https://docs.spring.io/spring-cloud-function/docs/4.0.0-SNAPSHOT/reference/html/aws.html
Update
I switched the spring-cloud-function version from 4.0.0.RELEASE to 3.2.6 and updated the Function class to remove the Message types. The lambda succeeds in test but fails when making the request from Postman to the API Gateway.
Function
public class Makeuser implements Function<APIGatewayRequest, User> {
#Override
public Message<User> apply(APIGatewayRequest request) {
...
return user;
}
}

Errors:
Even the client is not started at all
http://localhost:8080/
Error on console:
APPLICATION FAILED TO START
Description:
No spring.config.import property has been defined
Action:
Add a spring.config.import=configserver: property to your configuration.
If configuration is not required add spring.config.import=optional:configserver: instead.
To disable this check, set spring.cloud.config.enabled=false or
spring.cloud.config.import-check.enabled=false.
To use the legacy bootstrap way of connecting to Config Server,bootstrap must be enabled via a property or the spring-cloud-starter-bootstrap starter.The property is spring.cloud.bootstrap.enabled=true. It must be set as a System Property or environment variable. spring docs
After expending too much time I found two approach to fix this issues -
Basically we have to make the value of spring.cloud.bootstrap.enabled as true by default it is false. This was already mentioned in Spring Cloud doc but I didn't get this point at very first time. After finding the solution of this issue, the point of spring cloud doc has cleared.
First Approach: set the System environment variable in #SpringBootApplicationclass
public static void main(String[] args) throws IOException {
System.setProperty("spring.cloud.bootstrap.enabled","true");
run(Application.class, args);
}
Second Approach: An entry of dependency into pom.xml, it make spring.cloud.bootstrap.enabled

Getting java.lang.IllegalStateException when adding Openfeign dependency

I am creating rest based service using Spring Boot. It was working fine.
Now I added the below dependency
<dependency>

</dependency>
After adding this, Spring boot app stops working, it gives below error:

Can anybody help me in resolving this error?
Looks like your commons-lang-2.6.jar dependent jar in your local maven repo is corrupted.
Now in your case:
Delete the jar from :
file:/C:/Users/nicky/.m2/repository/commons-lang/commons-lang/2.6/
and rebuild your application.
In your pom.xml , below dependency
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign </artifactId>
</dependency>
has a space in artifactId after spring-cloud-starter-openfeign , please remove that.
It should work after above two things.
Hope this helps.

This is the Main Class:
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
#SpringBootApplication
#EnableJpaRepositories(repositoryFactoryBeanClass = DataTablesRepositoryFactoryBean.class)
public class IaasservicesportalApplication extends SpringBootServletInitializer{
public static void main(String[] args) {
SpringApplication.run(IaasservicesportalApplication.class, args);
}
}
The problem is that I can export the project as a WAR file to deploy into a Tomcat Server and It works fine. But I need to create a JAR file and execute that with the java -jar command.
When I execute the JAR file with java -jar command I get the following errors:
https://gist.github.com/jopse/5fb6833341f3398e00476df7ed1f5c25
I didn't found similar errors here. I found problems like jar command or jar exporting but not these errors
EDIT: Errors in gist.github.com instead of as code
EDIT: Added a dependency accidentally deleted
Finnally, I have added theese dependencies to a Nexus server.
I have added that Nexus server to the POM file
Resulting this code:

And finally my tomcat server code:
public void createTomcatServer() throws ServletException, LifecycleException{
Tomcat tomcat = null;
Integer webPort = new Integer(9696);
tomcat.setPort(webPort);
tomcat.addWebapp("/", new File(webappDirLocation).getAbsolutePath());
System.out.println("configuring app with basedir: " + new File("./" + webappDirLocation).getAbsolutePath());
tomcat.start();
tomcat.getServer().await();
}
I thought I had included all the correct dependencies, etc. But I just cant find out why its not working - I've looked all over google already - so any help would be greatly appreciated.
I encountered the same problem as well and solved it by depending on the embed module instead.
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-core</artifactId>
<version>${embedded.tomcat.version}</version>

Neo4j-spatial can't import OSM

I'm new to neo4j and trying to import an .osm data to my embeddedDatabase but it doesn't work. I searched for some example code and finally I ended up with this code which I got by trying to understand the TestOSMImport.java
private void importOSM(){
OSMImporter importer = new OSMImporter("map2.osm");
importer.setCharset(Charset.forName("UTF-8"));
try{
System.out.println("Bis hier");
GraphDatabaseService db = new GraphDatabaseFactory().newEmbeddedDatabase(DB_PATH);
importer.importFile(db, "map2.osm",false,5000,true);
System.out.println("start____ReIndex!");
importer.reIndex(db,10000);
db.shutdown();
}catch(Exception e){
System.out.println("__________Import Error!! "+e.getMessage());
e.printStackTrace();
}
}
The code is starting the reIndex method and then comes up with this error
Re-indexing with GraphDatabaseService: EmbeddedGraphDatabase [neo4j-community-1.9.4\data\graph.db] (class: class org.neo4j.kernel.EmbeddedGraphDatabase)

Can someone help me please find the solution??

You have to use a version of neo4-spatial that's built for the version of Neo4j you are using. Try changing
<version>0.12-neo4j-2.0.0-SNAPSHOT</version>
to
<version>0.11-neo4j-1.9</version>
