javascript - Spring Boot - 为什么我的应用程序找不到静态资源？

Question

我正在试用 Spring Boot，但无法访问 CSS、图像和 JS 文件。

我有这个@SpringBootApplication 类:

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

我的 application.properties文件内容如下:

spring.datasource.url=jdbc:mysql://localhost:3306/<schema>?autoReconnect=true&useSSL=false
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.name=<sql-databasename>
spring.datasource.username=<sql-username>
spring.datasource.password=<sql-password>
#spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database=MYSQL
spring.jpa.database-platform=org.hibernate.dialect.MySQLDialect
spring.jpa.show-sql=false 
spring.jpa.hibernate.ddl-auto=update

# EMBEDDED SERVER CONFIGURATION (ServerProperties)
server.context-path=/<application-name>
server.display-name=<application-name>
server.port=8080
server.session.cookie.max-age=3600

# SPRING MVC (WebMvcProperties)
spring.mvc.favicon.enabled=true
spring.mvc.date-format=dd/MM/yyyy
spring.mvc.locale=pt_BR
spring.mvc.locale-resolver=accept-header
spring.mvc.servlet.load-on-startup=-1
spring.mvc.static-path-pattern=/**

# SPRING RESOURCES HANDLING (ResourceProperties)
spring.resources.add-mappings=true
spring.resources.cache-period=1
spring.resources.static-locations=classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/**,classpath:/public/**

# THYMELEAF (ThymeleafAutoConfiguration)
spring.thymeleaf.cache=true
spring.thymeleaf.check-template-location=true
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html
spring.thymeleaf.mode=HTML5
spring.thymeleaf.encoding=UTF-8
spring.thymeleaf.content-type=text/html

纯粹是还没有完全理解 Spring Boot 是如何工作的，我一直没能摆脱这个配置文件:

@Configuration
@EnableAutoConfiguration
@ComponentScan(basePackages = "b.c.g.c")
public class CmsBootApplicationConfiguration extends WebMvcConfigurerAdapter {

    @Bean(name = "messageSource")
    @Description("Spring message resolver")
    public MessageSource messageSource() {
        ResourceBundleMessageSource messageSource = new ResourceBundleMessageSource();
        messageSource.setBasename("i18n/messages");
        messageSource.setFallbackToSystemLocale(false);
        messageSource.setCacheSeconds(0);
        messageSource.setDefaultEncoding("utf-8");
        return messageSource;
    }

    @Bean(name = "localeResolver")
    @Description("Spring locale resolver")
    public LocaleResolver localeResolver() {
        SessionLocaleResolver resolver = new SessionLocaleResolver();
        resolver.setDefaultLocale(new Locale("pt", "BR"));
        return resolver;
    }

    @Bean(name = "multipartResolver")
    public StandardServletMultipartResolver resolver() {
        return new StandardServletMultipartResolver();
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("classpath:/resources/**").addResourceLocations("/resources/");
    }

    @Bean
    public UrlTemplateResolver urlTemplateResolver() {
        return new UrlTemplateResolver();
    }
}

静态资源位于此处:

src/main/resources
    static
        css/
        img/
        js/

但是，当我尝试访问任何静态资源时，例如在下面的浏览器调用中:

http://localhost:8080/<application-name>/static/css/bootstrap.min.css

结果是:

{"timestamp":1472734923645,"status":404,"error":"Not Found","message":"No message available","path":"/cms/static/css/bootstrap.min .css”

但是文件是在那里...

我浏览了一下，但在 Spring Boot Reference Guide 找不到解决方案.

我做错了什么以及如何让它发挥作用？

删除 spring.resources.static-locations从你的配置，除非你想改变它，/static/默认包含。
资源在 static目录包含在 http 路径中。
引用资源时不包括 static .
文件src/main/resources/static/css/bootstrap.min.css应该可以在 http://localhost:8080/appname/css/bootstrap.min.css 上找到
