SpringBoot连接Presto，亲测有效

SpringBoot连接Presto，亲测有效

1. 配置依赖

    
    
      com.facebook.presto
      presto-jdbc
      0.203
    

2. 配置连接参数

#presto
spring.datasource.presto.name=presto
spring.datasource.presto.type=org.apache.tomcat.jdbc.pool.DataSource
spring.datasource.presto.driver-class-name=com.facebook.presto.jdbc.PrestoDriver
spring.datasource.presto.jdbc-url=jdbc:presto://127.0.0.1:8889/hive/test
spring.datasource.presto.username=root

3. 配置prestojdbc模板

@Slf4j
@Configuration
public class PrestoConfig {

    @Bean(name = "prestoDataSource")
    @ConfigurationProperties(prefix = "spring.datasource.presto")
    public DataSource prestoDataSource() {
        log.info("-------------------- presto init ---------------------");
        return DataSourceBuilder.create().build();
    }

    @Bean(name = "prestoTemplate")
    public JdbcTemplate prestoJdbcTemplate(@Qualifier("prestoDataSource") DataSource dataSource) {
        return new JdbcTemplate(dataSource);
    }
}

4. 使用模板

	@Autowired
	@Qualifier("prestoTemplate")
	private JdbcTemplate prestoTemplate;
