1.如果不是 /webjars/** 资源
if (!registry.hasMappingForPattern("/webjars/**")) { this.customizeResourceHandlerRegistration(registry.addResourceHandler(new String[]{"/webjars/**"}).addResourceLocations(new String[]{"classpath:/META-INF/resources/webjars/"}).setCachePeriod(this.getSeconds(cachePeriod)).setCacheControl(cacheControl)); } String staticPathPattern = this.mvcProperties.getStaticPathPattern(); if (!registry.hasMappingForPattern(staticPathPattern)) { this.customizeResourceHandlerRegistration(registry.addResourceHandler(new String[]{staticPathPattern}).addResourceLocations(WebMvcAutoConfiguration.getResourceLocations(this.resourceProperties.getStaticLocations())).setCachePeriod(this.getSeconds(cachePeriod)).setCacheControl(cacheControl)); }
spring boot 会通过这个 方法 getStaticLocations 查找
public String[] getStaticLocations() { return this.staticLocations; }
通过这个 方法返回 staticLocations 资源文件
private static final String[] CLASSPATH_RESOURCE_LOCATIONS = new String[]{"classpath:/META-INF/resources/", "classpath:/resources/", "classpath:/static/", "classpath:/public/"}; private String[] staticLocations; private boolean addMappings; private final ResourceProperties.Chain chain; private final ResourceProperties.Cache cache; public ResourceProperties() { this.staticLocations = CLASSPATH_RESOURCE_LOCATIONS; this.addMappings = true; this.chain = new ResourceProperties.Chain(); this.cache = new ResourceProperties.Cache(); }
从这里可以看出是一个数组
"classpath:/META-INF/resources/",
"classpath:/resources/",
"classpath:/static/",
"classpath:/public/"}
所以在项目中 我们可以将静态文件放入 这些文件夹中
