Spring boot allows defining datasource configuration in two ways: Java configuration. Properties configuration. During application startup, the DataSourceAutoConfiguration checks for DataSource.class (or EmbeddedDatabaseType.class) on the classpath and a few other things before configuring a DataSource bean for us.

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.. In addition, Spring Boot automatically configures a lightning-fast connection pool, either HikariCP, Apache Tomcat, or Commons DBCP, in that order, depending on which are on the classpath.

Spring Boot YAML Auto Data Source Configuration Issue - Data Source URL not picked up Hot Network Questions Can you determine the order of "at the end of a short rest" effects?

When dealing with just one datasource and Spring Boot, data source configuration is simple. Spring Boot can provide a lot of auto configuration. However, if you need to connect to multiple datasources with Spring Boot, additional configuration is needed. You need to provide configuration data to Spring Boot, customized for each data source.

To configure your own DataSource, define a Bean of that type in your configuration. Spring Boot reuses your DataSource anywhere one is required, including database initialization. If you need to externalize some settings, you can bind your DataSource to the environment (see "Section 25.8.1, "Third-party Configuration"").. The following example shows how to define a data source in a bean:

Spring Boot relies on HikariCP as the default connection pool. Adding in your project spring-boot-starter-jdbc or spring-boot-starter-data-jpa "starters" will automatically add a dependency to HikariCP with the default settings. It's important to know how to alter the configuration of your connection pool.

Build the blank project, if you get any Exception related to main class then create a class called JndiDatasourceApp under package com.roytuts.spring.boot.jndi.datasource with main method and try to build. Application Configuration. Create below application.properties file under src/main/resources directory.

We do this by adding the following configuration properties to application.properties: We can see now a property named spring.datasource.type that defines the type of DataSource to be used. This prompts Spring Boot to switch to Oracle UCP instead of HikariCP. There are additional properties that make sense for UCP as well.

1. Overview. Simply put, the Spring Boot autoconfiguration represents a way to automatically configure a Spring application based on the dependencies that are present on the classpath. This can make development faster and easier by eliminating the need for defining certain beans that are included in the auto-configuration classes.

Spring Boot auto-configuration attempts to automatically configure your Spring application based on the jar dependencies that you have added. For example, If HSQLDB is on your classpath, and you have not manually configured any database connection beans, then we will auto-configure an in-memory database. You need to opt-in to auto-configuration by adding the EnableAutoConfiguration or ...
