引入swagger-ui

在pom.xml檔案中引入swagger-ui修改的jar包

<dependency
 
>
    <groupId>io.springfox</groupId>

</dependency>

重新匯入pom，更新jar包

新增Swagger2Config類

解決swagger報swagger-resources/configuration/ui 404找不到異常：

package com.example.demo.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework
 
.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class Swagger2Config extends WebMvcConfigurerAdapter {
    private String basePackage = "com.example.demo.controller";

    @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/");
    }
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage(this.basePackage))
                .paths(PathSelectors.any()).build();
    }
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("FCat專案 APIs")
                .description("angular、spring cloud實戰專案：https://gitee.com/xfdm/FCat")
                .termsOfServiceUrl("http://fcat.xfdmao.com/")
                .contact(new Contact("fier", "http://blog.xfdmao.com", "[email protected]"))
                .version("1.0")
                .build();
    }
}
