Question

我使用Spring Boot主要是为一些静态内容提供一些基本的附加功能。

最近，我以某种方式设法通过以下方式将默认/视图映射到我的index.html：

@Configuration
@EnableAutoConfiguration
@EnableWebMvc
@ComponentScan
public class WebStarter extends WebMvcConfigurerAdapter {

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


    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("index.html");
    }

    public static void main(String[] args) throws Exception {
        run(WebStarter.class, args);
    }
}

现在我无法解决这个问题，我无法理解为什么。我只是得到以下异常：

javax.servlet.ServletException: Could not resolve view with name 'index.html' in servlet with name 'dispatcherServlet'

也许它与Spring Boot版本有某种联系，因为我最近在改变它。或者还有其他方法如何映射默认视图？

好吧，我解决了。不确定是否是coreect，但至少它是否有效。刚刚添加了我自己的资源解析器并注册了它。

    @Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
  registry.addResourceHandler("/").addResourceLocations("classpath:/www/").resourceChain(true).addResolver(new CustomResourceResolver("/", "/index.html"));
}

解析器：

public class CustomResourceResolver implements ResourceResolver {

private String requestPath;

private String resource;

public CustomResourceResolver(String requestPath, String resource) {
    this.requestPath = requestPath;
    this.resource = resource;
}

@Override
public Resource resolveResource(HttpServletRequest request, String requestPath, List<? extends Resource> locations, ResourceResolverChain chain) {

    if (!this.requestPath.equals(requestPath)) {
        return null;
    }

    try {

        for (Resource location : locations) {
            File file = new File(location.getFile(), resource);
            if (file.exists()) {
                return new FileSystemResource(file);
            }
        }

        return null;
    } catch (IOException e) {
        throw new RuntimeException(e);
    }
}

@Override
public String resolveUrlPath(String resourcePath, List<? extends Resource> locations, ResourceResolverChain chain) {
    return null;
}

在spring boot中使用java config的欢迎文件
