Quick Start

Approach 1: Direct Usage

@Bean
public DataSource beecpDataSrouce(){
  BeeDataSourceConfig config = new BeeDataSourceConfig(driver,url,user,password);
  return new BeeDataSource(config);
}

Approach 2: ?BeeCP-Starter (recommended)

# application.yml
spring:
  datasource:
    dsId: ds1,ds2
    ds1:
      primary: true
      poolName: ds1
      driverClassName: com.mysql.cj.jdbc.Driver
      jdbcUrl: jdbc:mysql://localhost:3306/test1
      password: root
      username: root
    ds2:
      poolName: ds2
      driver-class-name: com.mysql.cj.jdbc.Driver
      jdbc-url: jdbc:mysql://localhost:3306/test2
      password: root
      username: root

@Service
public class MyService{
  @AutoWired
  @Qualifier("ds1")
  private DataSource ds1;

  @AutoWired
  @Qualifier("ds2")
  private DataSource ds2;

  ......
}

Approach 3: Dynamic-datasource(recommended)

It is a data source management tool based on the Spring Boot platform, which is widely used in China.

More Properties

Release Approach

• Standalone Edition: Compatible with Java 7+ on lower versions (theoretically usable on higher Java versions as long as the com.sun.UnSafe class has not been removed).
• Combined Edition: Compatible with Java 17+ on higher versions, featuring a combined product suite of connection pool, object pool, task pool, etc. The following VM argument must be added at runtime: --add-exports java.base/jdk.internal.misc=ALL-UNNAMED.
