## springbootapplication爆红
|
||
|
|
|
||
|
|
```xml
|
||
|
|
原因就是在pom。xml中没有导入相关的依赖 就是
|
||
|
|
<dependency>
|
||
|
|
<groupId>org.springframework.boot</groupId>
|
||
|
|
<artifactId>spring-boot-starter</artifactId>
|
||
|
|
</dependency>
|
||
|
|
```
|
||
|
|
|
||
|
|
## 一切的起源@SpringBootApplication
|
||
|
|
|
||
|
|
```java
|
||
|
|
@SpringBootConfiguration -》@Configuration &&@Component
|
||
|
|
@EnableAutoConfiguration 自动导入包
|
||
|
|
@ComponentScan 扫描当前主启动类同级的包
|
||
|
|
```
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
## @ConfigurationProperties
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
这个@ConfigurationProperties 可以让类与ymal中的同名类进行赋值 当然 ```前提是prefix 要相同```
