Cant access Spring health endpoint - java

I can't access the actuator or swagger doc endpoints when I compile my app and run the jar from my target folder. But, I am able to access other endpoints with my app.
I can access these endpoints when I run my app directly from Intellj.
I think there must be some sort of problem with how I'm packaging my project in maven. I've included the pom.xml below.
application.properties
# Server
server.port = 9000
server.servlet.context-path = /api
# App
app.service_name = my-api
app.batch_limit = 100
# Health
management.endpoints.web.exposure.include = health,info
management.endpoint.health.show-details = ALWAYS
management.endpoints.web.base-path = /
management.endpoints.web.path-mapping.health = /_health
management.health.neo4j.enabled = false
DockerFile
FROM openjdk:17-alpine
RUN apk --no-cache add curl
WORKDIR /app
COPY ./my-api.jar /app/
COPY ./application.properties /app/config
EXPOSE 9000
CMD sleep 30 ; exec java $JAVA_OPTS -jar ./my-api.jar

From what you've posted, I assume that you deploy your application to a local docker container. You specify the health endpoint to be on port 9000 of the container. Which is not, by default, the same as port 9000 of your machine (a.k.a. localhost).
From the dockerfile reference documentation:
The EXPOSE instruction informs Docker that the container listens on the specified network ports at runtime. You can specify whether the port listens on TCP or UDP, and the default is TCP if the protocol is not specified.
The EXPOSE instruction does not actually publish the port. It functions as a type of documentation between the person who builds the image and the person who runs the container, about which ports are intended to be published. To actually publish the port when running the container, use the -p flag on docker run to publish and map one or more ports, or the -P flag to publish all exposed ports and map them to high-order ports.
(You could, in theory, run multiple containers on the same machine that all specify internally to listen to port 9000. On container startup, you would then map those container ports to different ports of your machine.)
When you run the application in Intellij, port 9000 there actually means port 9000 of your machine.

My project seems to build correctly when using the spring-boot-maven-plugin instead of maven-assembly-plugin. I can now access health and swagger endpoints.

Now if I run the program (from the project directory) with Maven : /pathTo/netbeans/java/maven/bin/mvn "-Dexec.args=-classpath %classpath" -DOMP_THREAD_LIMIT=1 -DskipTests=true exec:java the JPEG2000 dependency is loaded and the program works as expected.
However if I run the program (from the project directory) with Java : java -Dprism.order=sw --module-path /home/user/pathTo/lib/javafx-sdk-11.0.2/lib --add-modules ALL-MODULE-PATH -verbose:class -jar target/myBig-jar-with-dependencies.jar I get "org.apache.pdfbox.filter.MissingImageReaderException: Cannot read JPEG2000 image: Java Advanced Imaging (JAI) Image I/O Tools are not installed" although JAI and JPEG2000 do appear in loaded classes (see -verbose:class) :
[7,434s][info][class,load] com.github.jaiimageio.jpeg2000.impl.J2KImageReader source: file://path/to/project/target/myJar_with_dependencies.jar [7,434s][info][class,load] javax.imageio.ImageReadParam source: jrt:/java.desktop [7,435s][info][class,load] com.github.jaiimageio.jpeg2000.J2KImageReadParam source: file://path/to/project/target/myJar_with_dependencies.jar [7,435s][info][class,load] com.github.jaiimageio.jpeg2000.impl.J2KImageReadParamJava source: file://path/to/project/target/myJar_with_dependencies.jar [7,435s][info][class,load] com.github.jaiimageio.jpeg2000.impl.J2KMetadata source: file://path/to/project/target/myJar_with_dependencies.jar
To make the program work as expected with java I have to put the JPEG2000 jar in the lib path provided to the --module-path argument. But I'd rather only have clear dependencies in pom.xml to ease maintain the code in the future, instead of having also dependencies in the JavaFX lib folder in user directory.
So my question is what is the equivalent java command to the maven command shown above ?
Any help appreciated
Not sure this could help since it sounds more like wizardry! I updated to Tika 2.3 (moved tika-parser dependency to tika-parsers-standard-package) and as I got "package org.apache.tika.config does not exist" (although it does), I finally restarted Netbeans, built the jar, launched it via javacommand and it is now working as expected.

Not adding JARs to staging folder on Google Cloud when using Maven

I'm running integration tests on the cloud for the Google Cloud Dataflows that I have written; checking that they read from Pub/Sub and write to BigQuery correctly, but when using Maven (mvn clean install), the staging folder is not populated with the required JARs. The only JAR that appears is a surefirebooter.jar. As a result, I get a NoClassDefFoundError for PipelineOptions (most likely because it is the first class from a dependency that's trying to be referenced) in the Stackdriver logs, and consequently the tests fail. Since they're running on the cloud I am indeed using a DataflowRunner as opposed to a DirectRunner.
When I run the integration tests from my IDE they work fine; the staging folder is populated with all the JARs and all is well. Also, when I run the tests using Maven but with a DirectRunner the tests run successfully, thus my problem only occurs when using Maven and a DataflowRunner. I assume that problem therefore lies with the pom.xml file, which I have given below:

Anyone know why this is happening and how I may resolve it?
When staging files, the Dataflow runner will automatically stage the the classes available to the current class loader. I believe that surefire plays some tricks with the classloader to make the tests easier to run.
One option would be to specify filesToStage on the pipeline options, which will override the normal "detect JARs to stage from the class loader". Alternatively, look at how surefire is managing the classpath, and make sure the SDK JARs are available in the classloader the test is running in.

Heroku Spring Boot web service always return 404 but not on localhost

I have developed a web service which I am trying to deploy to Heroku. It seems successful though whenever I try to call one of my URL's I get a 404. I know it means that the resource is not available but it works fine on localhost.
The output from the Heroku deployment is the standard Spring boot but it is missing the:
2016-05-23 22:29:22.145 INFO 15785 --- [ main] s.w.s.m.m.a.RequestMappingHandlerMapping : Mapped "{[/home],methods=[GET]}" onto public org.springframework.http.ResponseEntity<java.util.List<entity.Giver>> controller.GiverController.getHomeContent(javax.servlet.http.HttpServletRequest)
lines I normally get from running the app on localhost (the output is just one of the many I have).
I have a suspicion that when Heroku boots my app the annotation mappings does not get "compiled" since it does not get printed in the logs but I am just guessing.
My Procfile:

The controllers are using #RestController as well as the #RequestMapping annotation for the path:
#RestController
public class GiverController {
#RequestMapping(value = "/home", method = RequestMethod.GET)
public ResponseEntity<List<Giver>> getHomeContent(HttpServletRequest request) {
List<Giver> homepageContent = GiverAPI.getHomePageContent();
if (homepageContent == null) {
return new ResponseEntity<List<Giver>>(HttpStatus.INTERNAL_SERVER_ERROR);
}
return new ResponseEntity<List<Giver>>(homepageContent, HttpStatus.OK);
}
}
The app is a Maven project containing a TomCat servlet with Spring Boot which package everything into a .jar file.
The Heroku CLI command I use for deployment is:
mvn clean heroku:deploy
I hope someone can help me.
The spring-boot-starter-parent POM includes <executions> configuration to bind the repackage goal. If you are not using the parent POM you will need to declare this configuration yourself. So, remove the maven-assembly-plugin and maven-jar-plugin plugin definitions and use the following:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>${spring.boot.version}</version>
<configuration>
<mainClass>controller.Application</mainClass>
<layout>ZIP</layout>
</configuration>
<executions>
<execution>
<goals>
<goal>repackage</goal>
</goals>
</execution>
</executions>
</plugin>
Also change the Procfile and use the new jar filename there. When you're not using the parent pom, this is the easiest way to create an executable jar. Checkout the Spring Boot documentation for more information.

How to use a custom library in Maven?

I am working on a software that uses Maven. My friend who works with me on it recently added a IO-Lib which makes it easier to handle packets sent by Minecaft: Pocket Edition Click here to see the software I'm talking about But, since the jar is not on the Maven Repo, I can use dependency the normal way. Is there anyway to use a custom library not in the maven repo?

If the custom jar file is not in maven central, the next best thing is for it to be in a different repo. If that's the case, you can add additional repository details to the pom.xml file and it will pull from both repos.
The second best thing is to use the "mvn install:install-file" target to manually install the binary into your cache. Then it will resolve in environments backed by your cache. If you have a build system that lives outside of your working environment, it gets just a little bit harder.
Assuming you have to make this work in multiple maven environments (not just your own) and you don't have a private repository, you need to create one. You can download various maven repository management systems (Artifactory, etc.) install them, and then configure your in-house repository the same way you would add a second out-of-house repository.
If setting up a repository server seems daunting to you, while it is far from a perfect solution, for a little while you can use the "mvn install:install-file" target to install the file in each local cache (but one typo or cache clear and it's going to be messed up in that cache)
You may want to add a system scoped dependency. have a look here:
https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Scope
it explains the various ways you can import a dependency. not all require the dependency be held in a repository.
I think this is what lhasadad was talking about, but to elaborate: I have used <scope>system</scope> and <systemPath>some/path/to.jar</systemPath> to point Maven at local jars successfully in the past. For example:
<dependency>
<groupId>org.apache</groupId>
<artifactId>kafka_2.8.2</artifactId>
<version>${kafka.version}</version>
<type>jar</type>
<scope>system</scope>
<systemPath>${basedir}/lib/kafka_2.8.2-${kafka.version}.jar</systemPath>
</dependency>
