這篇文章主要介紹了Springboot-swagger配置(idea社區(qū)版2023.1.4+apache-maven-3.9.3-bin),本文給大家介紹的非常詳細，對大家的學習或工作具有一定的參考借鑒價值，需要的朋友可以參考下

1、pom.xml的jar包引入

這里為了后文操作方便，我多添加了一個commons-lang3的包用于字符串的非空判斷。

    <!-- swagger包這里2.9.2 -->
    <dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-swagger2</artifactId>
      <version>2.9.2</version>
    </dependency>
    <dependency>
      <groupId>io.springfox</groupId>
      <artifactId>springfox-swagger-ui</artifactId>
      <version>2.9.2</version>
    </dependency>
    <!-- 用作字符串非空判斷 -->
    <dependency>
      <groupId>org.apache.commons</groupId>
      <artifactId>commons-lang3</artifactId>
      <version>3.12.0</version>
    </dependency>

2、創(chuàng)建【com.item.swagger】的配置文件【SwaggerConfig.java】

package com.item.swagger;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@Configuration
@EnableSwagger2
public class SwaggerConfig {
    private static Logger log = LoggerFactory.getLogger(SwaggerConfig.class);
    @Bean
    public Docket createRestApi() {
        log.info("進入到swagger的配置中");
        return new Docket(DocumentationType.SWAGGER_2)
                // 指定構(gòu)建api文檔的詳細信息的方法：apiInfo()
                .apiInfo(apiInfo())
                .groupName("紅目香薰·為大一孩子準備的")
                .select()
                // 指定要生成api接口的包路徑，這里把controller作為包路徑，生成controller中的所有接口
                .apis(RequestHandlerSelectors.basePackage("com.item.controller"))
                .paths(PathSelectors.any())
                .build();
    }
    /**
     * 構(gòu)建api文檔的詳細信息
     * @return
     */
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                // 設置頁面標題
                .title("Spring Boot集成Swagger2接口總覽")
                // 設置接口描述
                .description("Swagger接口")
                // 設置聯(lián)系方式
                .contact(new Contact("測試swagger","https://laoshifu.blog.csdn.net/",""))
                // 設置版本
                .version("1.0")
                // 構(gòu)建
                .build();
    }
}

配置文件在上文的代碼中就可以看到，并且我寫了很多注釋，應該是可以幫助到大家的。

3、示例swagger注解寫法

package com.item.controller;
import com.item.model.Users;
import com.item.service.UsersService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import org.apache.commons.lang3.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.*;
import javax.servlet.http.HttpServletRequest;
import java.util.HashMap;
import java.util.List;
@Api("用戶操作接口")
@RestController
@CrossOrigin
public class UsersController {
    @Autowired
    private UsersService usersService;
    /**
     * 獲取所有信息
     * @return
     */
    @GetMapping("/GetInfoApi")
    @ApiOperation(value = "獲取信息",notes = "沒啥留言的")
    public Object GetInfoApi(){
        List<Users> list=usersService.GetInfo();
        HashMap<String,Object> map=new HashMap<String,Object>();
        map.put("state",true);
        map.put("msg","成功");
        map.put("result",list);
        return map;
    }
    @GetMapping("/GetName")
    @ApiOperation(value = "獲取信息",notes = "沒啥留言的")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "nickName",required = true,paramType = "query",dataType = "String",value = "通過昵稱模糊查詢")
    })
    public Object GetName(HttpServletRequest request,Model model){
        String nickName = request.getParameter("nickName");
        List<Users> list=usersService.SelectName(nickName);
        HashMap<String,Object> map=new HashMap<String,Object>();
        map.put("state",true);
        map.put("msg","成功");
        map.put("result",list);
        return map;
    }
    /**
     * 添加信息
     * @param userName
     * @param pwd
     * @param nickName
     * @return
     */
    @PostMapping(value = "/UserAddInfoApi")
    @ApiOperation(value = "添加",notes = "沒啥留言的")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "userName",required = true,paramType = "query",dataType = "String",value = "用戶名"),
            @ApiImplicitParam(name = "pwd",required = true,paramType = "query",dataType = "String",value = "密碼"),
            @ApiImplicitParam(name = "nickName",required = true,paramType = "query",dataType = "String",value = "昵稱")
    })
    public Object UserAddInfoApi(String userName,String pwd,String nickName){
        HashMap<String,Object> map=new HashMap<String,Object>();
        if(
                StringUtils.isEmpty(userName)||
                        StringUtils.isEmpty(pwd)||
                        StringUtils.isEmpty(nickName)
        ){
            map.put("state",false);
            map.put("msg","參數(shù)不潤許為空");
            map.put("result","");
            return map;
        }
        usersService.UsersAddInfo(userName, pwd, nickName);
        map.put("state",true);
        map.put("msg","成功");
        map.put("result","");
        return map;
    }
    /**
     * 單個查詢
     * @param id
     * @return
     */
    @GetMapping("/UsersSelectById")
    @ApiOperation(value = "id查詢",notes = "沒啥留言的")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "id",required = true,paramType = "query",dataType = "String",value = "編號")
    })
    public Object UsersSelectById(String id){
        Users users = usersService.UsersSelectById(Integer.parseInt(id));
        HashMap<String,Object> map=new HashMap<String,Object>();
        map.put("state",true);
        map.put("msg","成功");
        map.put("result",users);
        return map;
    }
    /**
     * 修改api
     * @param id
     * @param pwd
     * @return
     */
    @PostMapping(value = "/UserUpdateInfoApi")
    @ApiOperation(value = "添加",notes = "沒啥留言的")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "id",required = true,paramType = "query",dataType = "String",value = "編號"),
            @ApiImplicitParam(name = "pwd",required = true,paramType = "query",dataType = "String",value = "密碼"),
    })
    public Object UserUpdateInfoApi(String id,String pwd){
        usersService.UsersUpdateInfo(pwd,Integer.parseInt(id));
        HashMap<String,Object> map=new HashMap<String,Object>();
        map.put("state",true);
        map.put("msg","成功");
        map.put("result","");
        return map;
    }
    /**
     * 刪除api
     * @param id
     * @return
     */
    @GetMapping(value = "/UsersDeleteById")
    @ApiOperation(value = "根據(jù)id刪除",notes = "沒啥留言的")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "id",required = true,paramType = "query",dataType = "String",value = "編號")
    })
    public Object UsersDeleteById(String id){
        usersService.UsersDeleteById(Integer.parseInt(id));
        HashMap<String,Object> map=new HashMap<String,Object>();
        map.put("state",true);
        map.put("msg","成功");
        map.put("result","");
        return map;
    }
}

4、swagger的常用注解

@Api：用于標識一個類為 Swagger 文檔的資源。用法示例：@Api(value = "User API", = "User Management")

@ApiOperation：用于描述一個方法的操作信息。用法示例：@ApiOperation(value = "Get user by ID", notes = "Returns a user based on ID")

@ApiParam：用于描述一個方法參數(shù)的信息。用法示例：@ApiParam(value = "User ID", required = true) @PathVariable("id") Long id

@ApiModel：用于描述一個數(shù)據(jù)模型（DTO）的信息。用法示例：@ApiModel(value = "User", description = "User details")

@ApiModelProperty：用于描述一個屬性或字段的信息。用法示例：@ApiModelProperty(value = "User name")

@ApiResponses：用于描述一個方法的多個響應。用法示例：@ApiResponses(value = { @ApiResponse(code = 200, message = "Success"), @ApiResponse(code = 404, message = "Not Found") })

@ApiIgnore：用于指定某個方法或類不在 Swagger 文檔中顯示。用法示例：@ApiIgnore

5、訪問效果

網(wǎng)頁的路徑是【http://127.0.0.1:8088/MyAPI/swagger-ui.html】，拼接方法是【ip:port/path/swagger-ui.html】

這里的path是在配置文件中的服務路徑【server.servlet.context-path=/MyAPI】

總結(jié)

swagger是比較常用的一種API交流插件，JAVA和.NET都用，且大多數(shù)程序員都會使用，方便大家交流API。
