不同环境运行不同的逻辑

		
@Configuration
public class DataSourceConfig {

    @Bean
    @Profile("dev")
    public DataSource devDataSource() {
        System.out.println(" dev DataSource !!");
        BasicDataSource basicDataSource = new BasicDataSource();
        basicDataSource.setDriverClassName("com.mysql.jdbc.Driver");
        basicDataSource.setUrl("jdbc:mysql://localhost:3308/neo");
        basicDataSource.setUsername("root");
        basicDataSource.setPassword("123456");
        return basicDataSource;
    }

    @Bean
    @Profile("prod")
    public DataSource prodDataSource() {
        System.out.println(" prod DataSource !!");
        BasicDataSource basicDataSource = new BasicDataSource();
        basicDataSource.setDriverClassName("com.mysql.jdbc.Driver");
        basicDataSource.setUrl("jdbc:mysql://localhost:3306/neo");
        basicDataSource.setUsername("root");
        basicDataSource.setPassword("123456");
        return basicDataSource;
    }
}
		
		

匹配多个环境

		
@Profile({"dev", "test", "grey", "prod"})
