Dynamic Datasource Spring Boot Starter

Spring Boot application integrates dynamic DataSource quickly.

Quickstart

• Import dependencies

    <dependency>
        <groupId>cn.unikue.springstarter</groupId>
        <artifactId>dynamic-datasource-spring-boot-starter</artifactId>
        <version>LATEST</version>
    </dependency>

By default, this starter will auto take effect, you can turn it off by spring.dynamic-datasource.enabled = false

• Configure Spring Boot application.yml with prefix spring.dynamic-datasource

spring:
    dynamic-datasource:
        datasource-route:
            testdb1:
                url: 'jdbc:mysql://127.0.0.1:3306/test_db1'
                driver-class-name: com.mysql.cj.jdbc.Driver
                type: com.zaxxer.hikari.HikariDataSource
            testdb2:
                url: 'jdbc:mysql://127.0.0.1:3306/test_db2'
                driver-class-name: com.mysql.cj.jdbc.Driver
                type: com.mchange.v2.c3p0.ComboPooledDataSource
            testdb3:
                url: 'jdbc:mysql://127.0.0.1:3306/test_db3'
                driver-class-name: com.mysql.cj.jdbc.Driver
                type: org.apache.commons.dbcp2.BasicDataSource

The identifiers (testdb1, testdb2, testdb3) are used as keys for switching several DataSource, they could be any names if you like, just attention that, these names must be alphanumeric.

• Annotate your (non-static) method with @DataSourceRouting annotation, done! Take one of the previous database testdb1 for example, the annotation is

    @DataSourceRouting(key = "testdb1")

Note that the key segment, that is the database identifier under your datasource-route node of the previous step.

• Optional feature: You can also define your databases in code (not just the application.properties), what you have to do is declaring DataSource beans with the @DataSourceDefinition annotation.

• This starter supports the most popular data source pools in the word, including

  • c3p0
  • dbcp2
  • druid
  • hikari
  • oracle ucp
  • tomcat
  • vibur
