中配置的静态位置对/**的请求进行评估 resourceProperties。

在应用程序上添加以下内容。属性，可能是你唯一需要做的事情…

spring.resources.static-locations=classpath:/myresources/

这将覆盖默认的静态位置，即:

ResourceProperties.CLASSPATH_RESOURCE_LOCATIONS = { "classpath:/META-INF/resources/",
        "classpath:/resources/", "classpath:/static/", "classpath:/public/" };

您可能不想这样做，只需确保您的资源最终位于这些默认文件夹中的一个。

执行请求: 如果我将example.html存储在/public/example.html 然后我可以像这样访问它:

<host>/<context-path?if you have one>/example.html

如果我想要另一个uri，如<host>/<context-path>/magico/*用于类路径:/magicofiles/*中的文件，则需要更多的配置

@Configuration
class MyConfigClass implements WebMvcConfigurer

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry.addResourceHandler("/magico/**").addResourceLocations("/magicofiles/");
}

如上所述，文件应该在$ClassPath/static/images/name.png， (/static or /public or /resources or /META-INF/resources)。这个$ClassPath表示main/resources或main/java目录。

如果你的文件不在标准dirs中，你可以添加以下配置:

@Configuration
@EnableWebSecurity
public class SecurityConfig extends WebSecurityConfigurerAdapter {

@Override
public void configure(WebSecurity web) throws Exception {
    web.ignoring().antMatchers("/lib/**"); // like this
}

@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) throws Exception {
        // ... etc.
}
...

}

给定src/main/resources/static下的资源， 如果你添加了这段代码，那么src/main/resources/static中的所有静态内容将在"/"下可用:

@Configuration
public class StaticResourcesConfigurer implements WebMvcConfigurer {
    public void addResourceHandlers(final ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("classpath:/resources/static/");
    }
}

不是说过了一年多才让死人复活，但之前所有的答案都忽略了一些关键点:

@EnableWebMvc on your class will disable org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration. That's fine if you want complete control but otherwise, it's a problem. There's no need to write any code to add another location for static resources in addition to what is already provided. Looking at org.springframework.boot.autoconfigure.web.ResourceProperties from v1.3.0.RELEASE, I see a field staticLocations that can be configured in the application.properties. Here's a snippet from the source: /** * Locations of static resources. Defaults to classpath:[/META-INF/resources/, * /resources/, /static/, /public/] plus context:/ (the root of the servlet context). */ private String[] staticLocations = RESOURCE_LOCATIONS; As mentioned before, the request URL will be resolved relative to these locations. Thus src/main/resources/static/index.html will be served when the request URL is /index.html. The class that is responsible for resolving the path, as of Spring 4.1, is org.springframework.web.servlet.resource.PathResourceResolver. Suffix pattern matching is enabled by default which means for a request URL /index.html, Spring is going to look for handlers corresponding to /index.html. This is an issue if the intention is to serve static content. To disable that, extend WebMvcConfigurerAdapter (but don't use @EnableWebMvc) and override configurePathMatch as shown below: @Override public void configurePathMatch(PathMatchConfigurer configurer) { super.configurePathMatch(configurer); configurer.setUseSuffixPatternMatch(false); }

恕我直言，在代码中减少错误的唯一方法就是不要尽可能地编写代码。使用已经提供的东西，即使这需要一些研究，但回报是值得的。

2021年7月编辑:

WebMvcConfigurerAdapter自Spring 5以来已弃用。实现WebMvcConfigurer并使用@Configuration进行注释。

我认为前面的回答很好地解决了这个问题。然而，我要补充的是，当你在应用程序中启用了Spring Security时，你可能必须明确地告诉Spring允许对其他静态资源目录的请求，例如“/static/fonts”。

在我的情况下，我有“/static/css”，“/static/js”，“/static/images”默认允许，但/static/fonts/**被我的Spring安全实现阻塞。

下面是我如何解决这个问题的示例。

@Configuration
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
.....
    @Override
    protected void configure(final HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/", "/fonts/**").permitAll().
        //other security configuration rules
    }
.....
}

只是为一个老问题补充另一个答案……人们已经提到@EnableWebMvc将阻止WebMvcAutoConfiguration加载，这是负责创建静态资源处理程序的代码。还有其他一些条件也会阻止WebMvcAutoConfiguration的加载。要明白这一点，最明确的方法是查看源代码:

https://github.com/spring-projects/spring-boot/blob/master/spring-boot-project/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/web/servlet/WebMvcAutoConfiguration.java#L139-L141

在我的例子中，我包括了一个库，它有一个从WebMvcConfigurationSupport扩展的类，这是一个将阻止自动配置的条件:

@ConditionalOnMissingBean(WebMvcConfigurationSupport.class)

重要的是不要从WebMvcConfigurationSupport扩展。相反，从WebMvcConfigurerAdapter扩展。

更新:正确的方法做到这一点在5。实现WebMvcConfigurer
