Thingsboard which is an IoT platform with the microservice architecture using Spring Boot 2 Flowable is a business process engines that are based on Spring and have already upgrade to support Spring Boot 2.0 Spring Initializr is the backend web API that can quickly generate a sample spring-boot project. It is exactly the backend API that powered the famous start.spring.io. Kafdrop is the web client that managing Kafka.

Answer : Why are you trying to roll your own solution. Spring-boot already supports that. If you don't already have one, add an application.properties file to src\main\resources . In that properties file, add 2 properties: server.contextPath=/mainstay server.port=12378 UPDATE (Spring Boot 2.0) As of Spring Boot 2.0 (due to the support of both Spring MVC and Spring WebFlux) the contextPath has been changed to the following: server.servlet.contextPath=/mainstay You can then remove your configuration for the custom servlet container. If you need to do some post processing on the container you can add a EmbeddedServletContainerCustomizer implementation to your configuration (for instance to add the error pages). Basically the properties inside the application.properties serve as a default you can always override them by using another application.properties next to the artifact you deliver or by adding JVM parameters ( -Dserver.port=6666 ).

Answer : As pointed put by Nicoll, With Spring Cloud Vault 3.0 and Spring Boot 2.4, the bootstrap context initialization ( bootstrap.yml , bootstrap.properties ) of property sources was deprecated . This can be fixed in one of the 2 ways Use Spring Boot 2.4.0 Config Data API to import configuration from Vault (Preferred) Legacy Processing: Enable the bootstrap context either by setting the configuration property spring.cloud.bootstrap.enabled=true or by including the dependency <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-bootstrap</artifactId> </dependency> 1. Use Spring Boot 2.4.0 Config Data API (Preferred) Move bootstrap.yml configuration to application.yml and updated file looks like below application.yml spring: cloud: vault: authentication: APPROLE app-role: role-id: ${role-id} secret-id: ${secret-id} role: pres-read app-role...

Answer : Not sure what you are trying to do but your @ContextConfiguration is useless as you aren't using Spring Test to run your test (that would require a @RunWith or one of the super classes from Spring Test). Next you are adding a singleton which is already fully mocked and configured (that is what the context assumes). I strongly suggest to use Spring instead of working around it. First create a configuration inside your test class for testing, this configuration should do the scanning and register the mocked bean. Second use Spring Test to run your test. @ContextConfiguration public class SoftwareServiceTests extends AbstractJUnit4SpringContextTests { private static final Logger LOGGER = LoggerFactory.getLogger(SoftwareServiceTests.class.getName()); @Autowired private SoftwareService softwareService; @Test(expected = ValidationException.class) public void testAddInvalidSoftware() throws ValidationException { LOGGER.info("Testing a...
