2.yam配置
# 端口号
server:
port: 8081
# 数据库
spring:
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
username: root
password: root
url: jdbc:mysql://127.0.0.1:3306/nodepad_mblog?useUnicode=true&characterEncoding=utf8&autoReconnect=true&serverTimezone=GMT%2B8
type: com.zaxxer.hikari.HikariDataSource
# sql日志打印
mybatis-plus:
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
3.启动类
// 我们这里还没有配置数据库，exclude = {DataSourceAutoConfiguration.class就是启动时不加载数据库
// @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class})
@Slf4j
@SpringBootApplication
public class BlogApplication {
public static void main(String[] args) {
ConfigurableApplicationContext context = SpringApplication.run(BlogApplication.class, args);
String port = context.getEnvironment().getProperty("server.port");
log.info("http://localhost:"+port);
}
}
