maven项目集成swagger

版本：
JDK 1.8
maven 3.5.2

首先pom添加依赖。

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.8.0</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.8.0</version>
        </dependency>

然后添加一个swagger2类

具体代码如下：

package com;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
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
@EnableWebMvc
public class Swagger2 {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //为当前包路径
                .apis(RequestHandlerSelectors.basePackage("com.jiang"))
                .paths(PathSelectors.any())
                .build();
    }
    //构建 api文档的详细信息函数,注意这里的注解引用的是哪个
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                //页面标题
                .title("Spring Boot测试使用 Swagger2 构建RESTful API")
                //创建人
                .contact(new Contact("Jiang", "http://www.baidu.com", "40061576@qq.com"))
                //版本号
                .version("1.0")
                //描述
                .description("API 描述")
                .build();
    }
}

但是这样之后，并不能正常的加载http://localhost:8080/swagger-ui.html，报错如下：

控制台报错如下：

2018-08-28 22:24:42.960  INFO 15720 --- [nio-8080-exec-1] o.s.web.servlet.DispatcherServlet        : FrameworkServlet 'dispatcherServlet': initialization completed in 12 ms
2018-08-28 22:24:42.968  WARN 15720 --- [nio-8080-exec-1] o.s.web.servlet.PageNotFound             : No mapping found for HTTP request with URI [/jiangyi/swagger-ui.html] in DispatcherServlet with name 'dispatcherServlet'

• 解决办法

增加一个配置类，用来匹配swagger-ui.html

package com.jiangyi.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.http.CacheControl;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

import java.util.concurrent.TimeUnit;

@Configuration
@EnableWebMvc
public class WebConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/")
                .setCacheControl(CacheControl.maxAge(1, TimeUnit.HOURS).cachePublic());
        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/")
                .setCacheControl(CacheControl.maxAge(1, TimeUnit.HOURS).cachePublic());
    }

}

这样就解决了上面路径找不到的问题了。访问http://localhost:8080/swagger-ui.html就可以正常显示了。
