Hi everyone,
i have found this repository from spring.io web site.
I'm trying to use a MySQL db with the code within this repository.

When i launch the maven command clean and package i receive the Build Success message, but if i launch the registration application, as the readme file describes, i receive the following java exception:

5977: WARN AnnotationConfigEmbeddedWebApplicationContext - Exception encountered during context initialization - cancelling refresh attempt org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaAutoConfiguration': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private javax.sql.DataSource org.springframework.boot.autoconfigure.orm.jpa.JpaBaseConfiguration.dataSource; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceAutoConfiguration$NonEmbeddedConfiguration.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Cannot determine embedded database driver class for database type NONE.

Hi @paulc4,
I'm a computer science student who's about to finish my career. I'm working on a project that involves making a website through microservices and to inform myself I've been analyzing your code.
My architecture would be based on four microservices: web-service, products-service, cart-service, and payment-service.This is where my doubt comes in.
You in the project have included the WebAccountsService and WebAccountsController classes to manage the account-service information. What would happen when I want to include controllers and services to handle information from the rest of the microservices? Should I create more classes of the style 'WebProductsController"? I don't think because there would be a project with many classes.
I also don't know if it would be good practice to create two classes, WebController and WebService, to handle all the information (WebService would contain all microservices access URLs).
I've searched the internet for information but I know there are several ways to approach web UI management in microservices.
Thanks! :)

Hi Paul! I'm here again.
I don't understand how the '--registration.server.hostname' parameter works when we run a container. I have been reading the parameters of the docker run command with docker run --help, but I don't understand the creation of this parameter.
I know that system environment variables exist, but that they are passed by parameter using: '--env Key-Value'. Isn't --registration.server.hostname a system environment variable?
I know that the value you enter in that parameter is replaced in the '.properties' file of each eureka client and that serves to indicate to the client where the registration server is, but I don't know how Docker understands that parameter because what's normal and what it says in the documentation is passing it as an environment variable.
I executed the order: 'docker run --name accounts --hostname accounts --network accounts-net -p 2222:2222 paulc4/microservice java -jar app.jar accounts --env registration.server.hostname= but it doesn't work, so I assume it's not the same.
Thanks!

I'm trying this demo on macOS. But you need some command-line build instructions. What gradle command do I invoke? I tried gradle jar, and that did something, but the results are in build/libs, not target.

Anyway, trying to run that jar, I get:

$ java -jar build/libs/microservices-demo-1.1.0.RELEASE.jar registration
no main manifest attribute, in build/libs/microservices-demo-1.1.0.RELEASE.jar

gradle build works better, but I get:

$ java -jar build/libs/microservices-demo-1.1.0.RELEASE.jar registration

The README.md file reads:
java -jar target/microservice-demo-0.0.1-SNAPSHOT.jar accounts 2223

But this jar file does not exist.

It should read:
java -jar target/microservice-demo-1.1.0.RELEASE.jar accounts 2223

I triedt this demo, It works great. All 3 services starts up, but Account service does not configure/start/initialize the embedded db (H2 or hsqldb?). Why? Also, it does not map any account controller urls like /accounts/{accountNumber} ???????

I get java.lang.IllegalArgumentException: Cannot find class [org.hibernate.cfg.ImprovedNamingStrategy]] when I do mvn clean package

Please see this question:

Hi Paul, I am getting a exception like below when I am trying to run RegistrationServer.java. Could you please help me?

As written this code does not work under Java 11. However it can be fixed by adding some dependencies to the pom file. I added the following dependencies and it seems to be working for me fine now.

        <dependency>
            <groupId>com.sun.xml.bind</groupId>
            <artifactId>jaxb-core</artifactId>

        </dependency>

I hope this helps anyone else trying to get this running with Java 11

Encountered "Error creating bean with name 'entityManagerFactory' defined in class path resource " while launching java -jar microservices-demo-1.1.0.RELEASE.jar registration. This error however is not triggered while launching from IDE.

Related to spring-projects/spring-boot#6635 and is fixable by upgrading spring boot version to 1.4.1

Hi Paul, I applied your demo and it worked great but I am getting 405 METHOD_NOT_ALLOWED exception when I am trying to send a POST request. I changed the code like below:

In WebAccountsController class:

FROM

@RequestMapping(value = "/accounts/search", method = RequestMethod.GET)
    public String searchForm(Model model) {
        model.addAttribute("searchCriteria", new SearchCriteria());
        return "accountSearch";
    }

TO

    @RequestMapping(value = "/accounts/search", method = RequestMethod.POST)
    @ResponseStatus(value=HttpStatus.OK)
    @ResponseBody
    public String searchForm(@ModelAttribute SearchCriteria searchCriteria, Model model) {
        model.addAttribute("searchCriteria", searchCriteria);
        return "accountSearch";
    }

In WebAccountsService class:

FROM

    public Account findByNumber(String accountNumber) {

        logger.info("findByNumber() invoked: for " + accountNumber);
        return restTemplate.getForObject(serviceUrl + "/accounts/{number}",
                Account.class, accountNumber);
    }   

TO

    public Account findByNumber(String accountNumber) {

        logger.info("findByNumber() invoked: for " + accountNumber);
        return restTemplate.postForObject(serviceUrl + "/accounts/",accountNumber,Account.class);
    }

and in accountSearch.html file:

What else should I change? Could you please help me?

In Readme, they mentioned to kill first account server and run the second one, how to kill the first instance server.?
Can we run more than one instance of a same service.If so,how to do it?Will the eureka dashboard displays how many instances of same service are running.
Do we need to change any port settings in the code?I have no idea how to do that. Please explain the whole project how it is running clearly.
Please reply me as soon as possible.
Appreciate your help.

Hi,

I'm running 1 registration, 1 web and 2 accounts, but when I close one of the accounts microservice sometimes I get the following error when I try a /accounts/123456789 :

I think it tries to send a request to the closed microservice, but it's already unregistered, it doesn't even show in the eureka's dashboard.

Thank you.

It looks like the README.md has a link to your blog article that isn't quite right:

Demo application to go with my Microservices Blog on the spring.io website.

Should this link point to:

Demo application to go with my Microservices Blog on the spring.io website.

...?

I get this error after i import the project in STS. Also i see the error when i try to run mvn build.

Project build error: Non-resolvable parent POM for org.springframework.samples.service.service:microservice-demo:0.0.1-SNAPSHOT: Failure to

Hi Paul ,

It was a very nice article and everything worked as expected but i have a question related to eureka console that it is displaying only account service count as 1 instead of 2 since i am running two instances of account service in my local machine . Is there any reason behind this ?

Thanks,
Akhil.

mvn clean package is failing with following error.
