web开发
1)、创建SpringBoot应用,选中我们需要的模块;
2)、SpringBoot已经默认将这些场景已经配置好了,只需要在配置文件中指定少量配置就可以运行起来
3)、自己编写业务代码;

自动配置原理?
这个场景SpringBoot帮我们配置了扫码?能不能修改?能不能改哪些配置?能不能扩展?xxx
xxxAutoConfiguration:帮我们给容器中自动配置组件;
xxxProperties:配置类来 封装配置文件的内容;

2、SpringBoot对静态资源的 映射规则

@ConfigurationProperties(prefix="spring.resources",ignoreUnknownFields=false)
public class ResourceProperties implements ResourceLoaderAware{

//可以设置和静态资源又关的的 参数,缓存时间

 1 public void addResourceHandlers(ResourceHandlerRegistry registry) {
 2     if (!this.resourceProperties.isAddMappings()) {
 3         logger.debug("Default resource handling disabled");
 4     } else {
 5         Duration cachePeriod = this.resourceProperties.getCache().getPeriod();
 6         CacheControl cacheControl = this.resourceProperties.getCache().getCachecontrol().toHttpCacheControl();
 7         if (!registry.hasMappingForPattern("/webjars/**")) {
 8             this.customizeResourceHandlerRegistration(registry.addResourceHandler(new String[]{"/webjars/**"}).addResourceLocations(new String[]{"classpath:/META-INF/resources/webjars/"}).setCachePeriod(this.getSeconds(cachePeriod)).setCacheControl(cacheControl));
 9         }
10 
11         String staticPathPattern = this.mvcProperties.getStaticPathPattern();
12         if (!registry.hasMappingForPattern(staticPathPattern)) {
13             this.customizeResourceHandlerRegistration(registry.addResourceHandler(new String[]{staticPathPattern}).addResourceLocations(getResourceLocations(this.resourceProperties.getStaticLocations())).setCachePeriod(this.getSeconds(cachePeriod)).setCacheControl(cacheControl));
14         }
15 
16     }
17 }
addResourceHandlers
