Therefore you need some mechanism by which you ensure that your method has been executed at least once. Example Project. Spring Boot provides a @SpringBootTest annotation which can be used as an alternative to the standard spring-test @ContextConfiguration annotation when you need Spring Boot features. This also increases code coverage of ResultSetExtractor code. Next define the class to configure route-package com.javainuse; import org.apache.camel.builder.RouteBuilder; public class SimpleRouteBuilder extends RouteBuilder { @Override public void configure() throws Exception { from("{{route.start}}").split().tokenize("\n").to("{{route.end}}"); } } Next define the xml configuration … For example, a DAO class should not encapsulate both the code for querying data over JDBC and the code for obtaining the JDBC connection. Spring boot H2 in-memory (or embedded) database example is a simple Spring boot application to demonstrate how to connect H2 database using Spring boot with JPA and test database results with a simple test case and from H2 console web browser.
