springboot整合swagger

1、Swagger简介

2、整合步骤

 项目整体架构如下：

        2.1  首先构建一个maven项目，添加依赖，我本项目只是一个子模块，所以相应的版本都是依赖于父版本的，看不到版本号，swagger使用的是2.9.2版本

<dependencies>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>
        </dependency>
</dependencies>

        2.2 创建Swagger配置类SwaggerConfig

package com.swagger.config;
 
import org.springframework.boot.autoconfigure.condition.ConditionalOnProperty;
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.WebMvcConfigurer;
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;
@Configuration
@ConditionalOnProperty(prefix = "swagger",value = {"enable"},havingValue = "true")
public class SwaggerConfig implements WebMvcConfigurer {
 
    @Bean
    public Docket buildDocket() {
        // 要扫描的API(Controller)基础包
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(buildApiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.swagger.controller"))
                .paths(PathSelectors.any())
                .build();
    }
 
    private ApiInfo buildApiInfo() {
        Contact contact = new Contact("开发者", "", "");
        return new ApiInfoBuilder()
                .title("测试‐应用API文档")
                .description("")
                .contact(contact)
                .version("1.0.0")
                .build();
    }
 
    /*** 添加静态资源文件，外部可以直接访问地址 ** @param registry */
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry
                .addResourceHandler("/**")
                .addResourceLocations("classpath:/static/");
        registry
                .addResourceHandler("swagger‐ui.html")
                .addResourceLocations("classpath:/META‐INF/resources/");
        registry
                .addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META‐INF/resources/webjars/");
    }
}

               2.3 在Controller层创建SwaggerController类方便测试，并添加swagger相应注解

package com.swagger.controller;
 
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
 
@Api(value = "测试平台 ",tags = "测试平台")
@RestController
public class SwaggerController {
 
    @ApiOperation("测试")
    @GetMapping(path = "/hello")
    public String hello(){
        return "hello";
    }
 
    @ApiOperation("测试2")
    @ApiImplicitParam(name = "name",value = "姓名",required = true,dataType = "string")
    @GetMapping("/hi")
    public String hi(String name){
        return "hi : "+name;
    }
}

常用Swagger注解如下：

@Api：修饰整个类，描述Controller的作用 @ApiOperation：描述一个类的一个方法，或者说一个接口

@ApiParam：单个参数的描述信息

@ApiModel：用对象来接收参数

@ApiModelProperty：用对象接收参数时，描述对象的一个字段

@ApiResponse：HTTP响应其中1个描述

@ApiResponses：HTTP响应整体描述

@ApiIgnore：使用该注解忽略这个API

@ApiError ：发生错误返回的信息

@ApiImplicitParam：一个请求参数

@ApiImplicitParams：多个请求参数的描述信息

  2.4 创建启动类SwaggerApplication 

package com.swagger;
 
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
 
@SpringBootApplication
@EnableSwagger2     //开启swagger
public class SwaggerApplication {
    public static void main(String[] args) {
        SpringApplication.run(SwaggerApplication.class,args);
    }
}

2.5 启动SwaggerApplication ，访问http://localhost:8080/swagger-ui.html
