SpringBoot 整合 pgSQL? 看这一篇就够了

SpringBoot 整合 pgSQL? 看这一篇就够了

---

一、导入XML依赖

		<dependency>
			<groupId>org.postgresql</groupId>
			<artifactId>postgresql</artifactId>
		</dependency>

二、配置yaml文件

spring:
  datasource:
    driver-class-name: org.postgresql.Driver
    username: postgres
    password: *******
    url: jdbc:postgresql://127.0.0.1:5432/postgres

三、简单测试

@Slf4j
@SpringBootTest
class Boot05WebAdminApplicationTests {

    @Autowired
    JdbcTemplate jdbcTemplate;

    @Test
    void contextLoads() {
//        jdbcTemplate.queryForObject("select * from account_tbl")
//        jdbcTemplate.queryForList("select * from account_tbl",)
        Long aLong = jdbcTemplate.queryForObject("select count(*) from account_tbl", Long.class);
        log.info("记录总数：{}",aLong);
    }
}
