Spring Boot索引未加载 - java

我有一个Spring Boot应用程序。

我没有使用@EnableWebMvc，并且我的资源在src/main/resources/static文件夹中。当我尝试加载localhost:8080/ui/时，它只是下载一个随机文件（类型：八位字节流）。如果我直接使用/ui/index.html则可以。

我也在使用WebSecurityConfigurerAdapter，但这似乎不是问题的原因。

有人遇到过吗？我希望在我请求localhost:8080/ui/时加载index.html文件

Spring Boot索引未加载 - java

我如何开始申请：

package my.package;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

//@EnableWebMvc //Breaks js resource loading
@SpringBootApplication
@EnableJpaRepositories
@EnableZuulProxy
public class MyApplication {

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

参考方案

Spring Boot将自动添加位于以下任何目录中的静态Web资源：Link

/META-INF/resources/
/resources/
/static/
/public/

默认情况下，Spring Boot从“ / static”（或“ / public”）的类路径中的资源中提供静态内容。

index.html资源是特殊的，因为它用作“欢迎页面”（如果存在），这意味着它将用作根资源，即在我们的示例中为http://localhost:8080/。 Link

对于您的情况，您需要告诉index.html的春季位置

public class MyApplication {


    @Bean
    WebMvcConfigurer configurer () {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addResourceHandlers (ResourceHandlerRegistry registry) {
                registry.addResourceHandler("/ui/").
                          addResourceLocations("classpath:/static/ui/index.html");
            }
        };
    }


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