2.自动依赖配置

3.核心注解@SpringBootApplication

这里主要关注@SpringBootApplication注解，它包括三个注解：

@Configuration：表示将该类作用springboot配置文件类。

@EnableAutoConfiguration:表示程序启动时，自动加载springboot默认的配置。

@ComponentScan:表示程序启动是，自动扫描当前包及子包下所有类。

 

4.Spring Boot 非web应用程序实例

5.JavaConfig注入方式

6.集成log4j2

boot默认是logback

Logger.getLogger()和LogFactory.getLog()的区别

1.Logger.getLogger()是使用log4j的方式记录日志；

2.LogFactory.getLog()则来自apache的common-logging包

3.LoggerFactory.getLogger()则来自slf4j的包

logback:

oracle批量更新和插入(sql形式)：https://www.cnblogs.com/feixian/p/5960111.html

Cause: java.sql.SQLSyntaxErrorException: ORA-01745: 无效的主机/绑定变量名;

https://www.aliyun.com/jiaocheng/787683.html

因为拼接sql方式一旦数据量超过3000以上，sql长度有限制！！只能采用jdbc方式批量插入

单元测试@springboottest  报错Failed to load ApplicationContext，默认走logback

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest

@Test
