Details

Actuator
Already covered at large in the migration part, Actuator now runs natively on Spring MVC, Spring WebFlux and Jersey. Adding the dependency and enabling web endpoints (using for instance endpoints.default.web.enabled) is all that’s required.

Another important change is that there is no longer a separate security auto-configuration for the Actuator:(management.security.enabled) no longer exists and web endpoints are disabled by default (endpoints.default.web.enabled) to prevent exposing sensitive information by default. The sensitive flag of each endpoint is also gone to make things more explicit in the security configuration. To restore the previous behaviour:

Enable Actuator web endpoints: endpoints.default.web.enabled=true in your configuration

Create or adapt your security configuration to secure endpoints with the role of your choice (see the Security section below)

M5
Management Server-related properties have been moved from management.* to management.server.*. We also fixed the meaning of management.server.context-path: it is now the endpoint management equivalent of server.context-path (only active when management.server.port is set). Additionally, you can also set the base path for the management endpoints with a new, separate property: management.endpoints.web.base-path.

For example, if you’ve set management.server.context-path=/management and management.endpoints.web.base-path=/application, you’ll be able to reach the health endpoint at the following path: /management/application/health.

M6
After some feedback from the community, the default management.endpoints.web.base-path has been changed from "/application" to "/actuator" to avoid collision with user-defined mappings (see #10970).

The endpoints. keys have moved to management.endpoints.


RC1
Spring Security default user
We’ve restored the ability to auto-configure a single user via configuration keys. These can be found at spring.security.user.
  • OAuth 2.0 Support Functionality from the Spring Security OAuth project is being migrated to core Spring Security. OAuth 2.0 client support has already been added and additional features will be migrated in due course.
If you depend on Spring Security OAuth features that have not yet been migrated you will need to add org.springframework.security.oauth:spring-security-oauth2 and configure things manually. If you only need OAuth 2.0 client support you can use the auto-configuration provided by Spring Boot 2.0. We’re also continuing to support Spring Boot 1.5 so older applications can continue to use that until an upgrade path is provided.
  • Jackson serialization
The default value for spring.jackson.serialization.write-dates-as-timestamps is now set to false, meaning all JSR310 date types will be serialized as ISO-8601 strings instead of array-like types.

RC1

Jackson
SerializationFeature.WRITE_DATES_AS_TIMESTAMPS is now disabled by default.

Date conversion
It is possible to control the date format for date types from well-known packages (java.util, org.joda.time and java.time) using a single property.

Spring Cloud

https://github.com/spring-projects/spring-cloud/wiki/Spring-Cloud-Finchley-Release-Notes

  • Remove the Zipkin Stream server spring-cloud/spring-cloud-sleuth#727
  • All of Feign code from Spring Cloud Netflix has been moved to a new project, Spring Cloud OpenFeign
  • spring-cloud-starter-eureka is deprecated. It is now called spring-cloud-starter-netflix-eureka-client

Java 9 vs Java 8

<properties>
    <!-- Generic properties -->
    <java.version>9</java.version>
</properties>

java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException

Affects all modules using JPA

Hibernate typically requires JAXB that’s no longer provided by default. You either need to add a dependency to your project:

<dependency>
    <groupId>javax.xml.bind</groupId>
    <artifactId>jaxb-api</artifactId>
</dependency>

Project Updates

REST Web Services

Actuator

Replace old url - http://localhost:8080/application New URL - http://localhost:8080/actuator

application.properties

management.endpoints.web.exposure.include=*

In HAL Browser, enter the actuator URL to browse.

Spring Security

#security.user.password=password
spring.security.user.name=username
spring.security.user.password=password

Internationalization!

    @GetMapping("/hello")
    public String helloWorld() {
        return msgSource.getMessage("msg.hello", null, "Whoops!", LocaleContextHolder.getLocale());
    }
    @Bean

Limits Service is Not Working

Hye ranga im also getting ouput as 0 and 0 ,and when i see in console it was able to fetch config from server at http://localhost:8888 and on the second line its saying

Could not locate PropertySource: I/O error on GET request for "http://localhost:8888/limits-service/default": Connection refused: connect; nested exception is java.net.ConnectException: Connection refused: conn

Can you give this a try? file:\\C:/Users/SOME-FOLDER/git-localconfig-repo

Answers to Questions

application.properties to bootstrap.properties application.properties -> Typical Spring Boot Configuration file.

bootstrap.properties -> When we use Spring Cloud Config Server, the configuration is in the config server. In this case, we use bootstrap.properties to specify the location of config server.

The current code event works with @ControllerAdvice annotation alone. What is benefit that we get by adding the @RestController annotation. @RestControllerAdvice https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/bind/annotation/RestControllerAdvice.html @RestController (because of @ResponseBody) indicates that return value of method will be the response returned for the request. However, since Java object cannot be part of a HTTP response, the object is transformed to the request response format using format converters.

A better option is to use @RestControllerAdvice instead of both @RestController and @ControllerAdvice. Here’s the Java Doc - https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/web/bind/annotation/RestControllerAdvice.html

RestControllerAdvice = ControllerAdvice + ResponseBody

Could not locate PropertySource: I/O error on GET request for "http://localhost:8888/limits-service/default": Connection refused: connect; nested exception is

java.net.ConnectException: Connection refused: connect

Scope of a microservice

I have one very basic doubt on how to decide if this is the scope of microservice.

For example If I have to create microservices for Employee Software,

So 1. Will Insert, update, Delete Employee should be part of microservice?

  1. Department information in which Employee belongs should be part of another Service?

Could you please help me with some pointer, details, ref ... so that I can understand how to break requirement into microservices? Because just mentioning that it should serve one specific business need, should be deployable seprately doent helping much in practical scenario,

The scope of the microservice is the most difficult choice you have to make. There is no one good answer to it.

One thing I can confirm is that all operations (insert, update, delete) should be part of the same micro service.

However, should Employee be a micro service on its own? Can I combine with Department? These are things that we will not be able to answer unless we know the business domain, how they would evolve, how dependent these are and what are the relative sizes?

A good starting point is to understand Bounded Context. https://martinfowler.com/bliki/BoundedContext.html

Use that as the starting point but be flexible to allow evolution of it.

I think the thought process about transaction management should be a little different with micro services. As you can read here - https://softwareengineering.stackexchange.com/questions/290917/what-is-the-most-accepted-transaction-strategy-for-microservices - it is a very complex topic.

Here’s a good description of an event driven solution - https://www.nginx.com/blog/event-driven-data-management-microservices/

Deployment of Microservices

I’ve seen a number of installations of micro services using embedded tomcat!

Docker is an awesome containerisation tool. You can check out how to use it in combination with spring boot here - https://spring.io/guides/gs/spring-boot-docker/
