Deinum's comment You need to specify the JPA configuration information as the Spring RestBucks App is using Spring Data JPA.. HikariCP, Tomcat Pooling and Commons DBCP2. I have deployed my Spring Boot web app in Azure cloud. Use jdbcUrl configuration instead. Here is a list of JDBC DataSource classes for popular databases: As you can see, with Spring Boot we have to specify only few dependencies: Spring Boot Starter Web, Spring Boot Data JPA, Spring Boot ThymeLeaf and MySQL JDBC driver. As soon as we include spring-boot-starter-data-jpa into our pom.xml, we'll transitively include a dependency to the Tomcat JDBC implementation. Spring Boot : Steps to Configure JNDI DataSource with External Tomcat. We can do so in the application.properties file:. In Spring Boot 2.0 release, default database pooling technology has been switched from Tomcat Pool to HikariCP. Configuration for Spring Datasource, JPA & Hibernate in application.properties. writing only repository interfaces that extend CrudRepository / JpaRepository.And Spring Boot makes it In addition when the reverse proxy terminates the https connection, it may be necessary to configure server.forward-headers-strategy=native (also see Spring Boot Reference Guide). Spring Boot uses an opinionated algorithm to scan for and configure a DataSource.This allows us to easily get a fully-configured DataSource implementation by default.. For example, a commonly requested setup is to (1) Spring Boot 2 configures a composite MeterRegistry to which any number of registry implementations can be added, allowing you to ship your metrics to more than one monitoring system. The easiest, which also sets a default configuration repository, is by launching it with spring.config.name=configserver (there is a configserver.yml in the Config Server jar). As soon as we include spring-boot-starter-data-jpa into our pom.xml, we'll transitively include a dependency to the Tomcat JDBC implementation. server.contextPath=/ debug=true # Spring data source needed for Spring boot to behave # Pre Spring Boot v2.0.0.M6 without below Spring Boot defaults to tomcat-jdbc connection pool included # in spring-boot-starter-jdbc and as compiled dependency under spring-boot-starter-data-jpa spring.datasource.type=com.zaxxer.hikari.HikariDataSource Use Spring web tool or your development tool (Spring Tool Suite, Eclipse, Intellij) to create a Spring Boot project.
