java - 无法让 springfox-swagger-ui 与 Spring MVC 一起工作

Question

我花了几天时间寻找并未能找到解决方案，大多数示例处理 spring boot 和 gradle，我只使用 spring mvc 和 maven。

如果我删除 springfox-swagger-ui 依赖项，应用程序运行正常，并且以下返回 JSON 符合预期 http:\\localhost:8080\restful\v2\api-docs?group=restful-api

出于某种原因，我的 spring 应用程序无法通过 swagger-ui.html，如果我设置 index.html，它会给出相同的响应

我试过添加:

1. web.xml 中的欢迎列表文件
2. 资源处理程序
3. 默认 Servlet 处理

没有效果。

应用配置

package au.com.speak.restful.spring;

import org.springframework.context.MessageSource;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.support.ReloadableResourceBundleMessageSource;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import     org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.i18n.CookieLocaleResolver;
import org.springframework.web.servlet.i18n.LocaleChangeInterceptor;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "au.com.speak.restful.api" })
public class AppConfig extends WebMvcConfigurerAdapter {

    // ========= Overrides ===========

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new LocaleChangeInterceptor());
    }

    // ========= Beans ===========

    @Bean(name = "localeResolver")
    public LocaleResolver getLocaleResolver() {
        return new CookieLocaleResolver();
    }

    @Bean(name = "messageSource")
    public MessageSource getMessageSources() {
        ReloadableResourceBundleMessageSource messageSource = new     ReloadableResourceBundleMessageSource();
        messageSource.setBasenames("/WEB-INF/resources/properties/error", "/WEB-INF/resources/properties/validation");
        messageSource.setCacheSeconds(0);

        return messageSource;
    }
}

Swagger 配置

package au.com.speak.restful.spring;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig  {

    @Bean
    public Docket restfulApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("restful-api")
                .select()
                .build()
                .apiInfo(apiInfo());
    }

    private ApiInfo apiInfo() {

        ApiInfo apiInfo = new ApiInfo(
                "My Apps API Title",
                "My Apps API Description",
                "My Apps API Version",
                "My Apps API terms of service",
                "My Apps API Contact Email",
                "My Apps API Licence Type",
                "My Apps API License URL"
        );
        return apiInfo;
    }
}

我的代码如下:

通过将以下内容添加到 AppConfig 中进行修复。

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    registry
        .addResourceHandler("swagger-ui.html")
        .addResourceLocations("classpath:/META-INF/resources/");
    registry
        .addResourceHandler("/webjars/**")
        .addResourceLocations("classpath:/META-INF/resources/webjars/");
}
