【问题描述】：

在尝试访问 Swagger 文档时，我遇到了这个错误：

Whitelabel 错误页面此应用程序没有明确的映射 /error，因此您将其视为后备。

Wed Sep 23 09:38:17 BRT 2020 There was an unexpected error (type=Not 找到，状态=404）。没有可用的消息

我不知道会是什么......

pom.xml：

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>3.0.0</version>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>3.0.0</version>
        </dependency>

类配置：

package com.simulacao.api.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
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 bancoApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.simulacao.api"))
                .paths(PathSelectors.regex("/*.*"))
                .build()
                .apiInfo(metaInfo());
    }

    private ApiInfo metaInfo() {
        return new ApiInfoBuilder()
                .title("API Rest")
                .description("\"API Rest\"")
                .version("1.0.0")
                .license("Apache License Version 2.0")
                .licenseUrl("https://www.apache.org/licenses/LICENSE-2.0\"")
                .build();
    }
}

控制器：

@RestController
@RequestMapping(value = "/api/customer")
@Api(value = "API Rest Customer")
@CrossOrigin(origins = "*")
public class CustomerController {

    @Autowired
    private CustomerService customerService;

    @Autowired
    private AccountService accountService;

    @Autowired
    private CustomerRepository customerRepository;

    @GetMapping
    @ApiOperation(value = "Returns a list of customers")
    public ResponseEntity<List<Customer>> showAll() {
        return ResponseEntity.ok(this.customerService.findAll());
    }

标签： java spring-boot swagger

【解决方案1】：

请添加这些配置

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {


    //Swagger UI property
    registry.addResourceHandler("swagger-ui.html")
            .addResourceLocations("classpath:/META-INF/resources/");

    registry.addResourceHandler("/webjars/**")
            .addResourceLocations("classpath:/META-INF/resources/webjars/");
}

这必须在实现的配置中用“WebMvcConfigurer”声明。

【解决方案2】：

对于带有 SpringFox 3 的 Spring Boot，您只需要以下内容：

    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-boot-starter</artifactId>
        <version>3.0.0</version>
    </dependency>

而/swagger-ui.html 现在是/swagger-ui/index.html 或/swagger-ui。来自doc

swagger-ui 位置已从 http://host/context-path/swagger-ui.html 移动到 http://host/context-path/swagger-ui/index.html 或 http://host/简称context-path/swagger-ui/
