我是靠谱客的博主自觉电源，最近开发中收集的这篇文章主要介绍SpringBoot中部署Swagger2和Swagger-UI，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1 Gradle配置
在dependencies中添加以下依赖：

implementation("io.springfox:springfox-swagger2:2.7.0")
implementation("io.springfox:springfox-swagger-ui:2.7.0")

具体的版本可以在https://mvnrepository.com/artifact/io.springfox中查看到

2 添加Swagger2配置类

package com.learning.test;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
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;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableWebMvc
@EnableSwagger2
public class Swagger2Configuration implements WebMvcConfigurer {
  
//swagger2的配置文件，这里可以配置swagger2的一些基本的内容，比如扫描的包等等
  @Bean
  public Docket createRestApi() {
    return new Docket(DocumentationType.SWAGGER_2)
        .apiInfo(apiInfo())
        .select()
        .apis(RequestHandlerSelectors.basePackage("com.learning.test.controller"))
        .paths(PathSelectors.any())
        .build();
  }

  // 构建api文档的详细信息
  private ApiInfo apiInfo() {
    return new ApiInfoBuilder()
        // 页面标题
        .title("API接口说明")
        // 创建人
        .contact(new Contact("lasdaybg", "", ""))
        // 版本号
        .version("")
        // 描述
        .description("")
        .build();
  }
  
  @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/");
  }
}

3 Controller示例

package com.learning.test.controller;

import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import com.learning.test.model.MyObject;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;

@RestController
@RequestMapping(value = "/test")
@Api("测试接口")
public class TestController {
  @RequestMapping(method = RequestMethod.GET)
  @ApiOperation(value = "查询对象")
  @ApiImplicitParams({
      @ApiImplicitParam(name = "param1", value = "入参1"),
      @ApiImplicitParam(name = "param2", value = "入参2")})
  public MyObject get(@RequestParam(required = false) String param1,
                      @RequestParam(required = false) String param2) {
    return new MyObject();
  }

  @RequestMapping(method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_UTF8_VALUE)
  @ApiOperation(value = "创建对象")
  public void create(@RequestBody(required = false) MyObject myObject) {}
}

MyObject的类声明如下：
package com.learning.test.model;

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;

@Data
@ApiModel(value = "MyObject", description = "数据模型")
public class MyObject {

  @ApiModelProperty(value = "名称")
  private String name;

  @ApiModelProperty(value = "参数1")
  private Integer param1;

  @ApiModelProperty(value = "参数2")
  private Boolean param2;
}
