这篇文章主要介绍了Springboot-swagger配置(idea社区版2023.1.4+apache-maven-3.9.3-bin),本文给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下

本文是配置swagger的文章，版本是【2.9.2】

1、pom.xml的jar包引入

这里为了后文操作方便，我多添加了一个commons-lang3的包用于字符串的非空判断。

    <!-- swagger包这里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>
    <!-- 用作字符串非空判断 -->
    <dependency>
      <groupId>org.apache.commons</groupId>
      <artifactId>commons-lang3</artifactId>
      <version>3.12.0</version>
    </dependency>

2、创建【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("进入到swagger的配置中");
        return new Docket(DocumentationType.SWAGGER_2)
                // 指定构建api文档的详细信息的方法：apiInfo()
                .apiInfo(apiInfo())
                .groupName("红目香薰·为大一孩子准备的")
                .select()
                // 指定要生成api接口的包路径，这里把controller作为包路径，生成controller中的所有接口
                .apis(RequestHandlerSelectors.basePackage("com.item.controller"))
                .paths(PathSelectors.any())
                .build();
    }
    /**
     * 构建api文档的详细信息
     * @return
     */
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                // 设置页面标题
                .title("Spring Boot集成Swagger2接口总览")
                // 设置接口描述
                .description("Swagger接口")
                // 设置联系方式
                .contact(new Contact("测试swagger","https://laoshifu.blog.csdn.net/",""))
                // 设置版本
                .version("1.0")
                // 构建
                .build();
    }
}

配置文件在上文的代码中就可以看到，并且我写了很多注释，应该是可以帮助到大家的。

3、示例swagger注解写法

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("用户操作接口")
@RestController
@CrossOrigin
public class UsersController {
    @Autowired
    private UsersService usersService;
    /**
     * 获取所有信息
     * @return
     */
    @GetMapping("/GetInfoApi")
    @ApiOperation(value = "获取信息",notes = "没啥留言的")
    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 = "获取信息",notes = "没啥留言的")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "nickName",required = true,paramType = "query",dataType = "String",value = "通过昵称模糊查询")
    })
    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 = "没啥留言的")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "userName",required = true,paramType = "query",dataType = "String",value = "用户名"),
            @ApiImplicitParam(name = "pwd",required = true,paramType = "query",dataType = "String",value = "密码"),
            @ApiImplicitParam(name = "nickName",required = true,paramType = "query",dataType = "String",value = "昵称")
    })
    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","参数不润许为空");
            map.put("result","");
            return map;
        }
        usersService.UsersAddInfo(userName, pwd, nickName);
        map.put("state",true);
        map.put("msg","成功");
        map.put("result","");
        return map;
    }
    /**
     * 单个查询
     * @param id
     * @return
     */
    @GetMapping("/UsersSelectById")
    @ApiOperation(value = "id查询",notes = "没啥留言的")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "id",required = true,paramType = "query",dataType = "String",value = "编号")
    })
    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 = "没啥留言的")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "id",required = true,paramType = "query",dataType = "String",value = "编号"),
            @ApiImplicitParam(name = "pwd",required = true,paramType = "query",dataType = "String",value = "密码"),
    })
    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;
    }
    /**
     * 删除api
     * @param id
     * @return
     */
    @GetMapping(value = "/UsersDeleteById")
    @ApiOperation(value = "根据id删除",notes = "没啥留言的")
    @ApiImplicitParams({
            @ApiImplicitParam(name = "id",required = true,paramType = "query",dataType = "String",value = "编号")
    })
    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：用于标识一个类为 Swagger 文档的资源。用法示例：@Api(value = "User API", = "User Management")

@ApiOperation：用于描述一个方法的操作信息。用法示例：@ApiOperation(value = "Get user by ID", notes = "Returns a user based on ID")

@ApiParam：用于描述一个方法参数的信息。用法示例：@ApiParam(value = "User ID", required = true) @PathVariable("id") Long id

@ApiModel：用于描述一个数据模型（DTO）的信息。用法示例：@ApiModel(value = "User", description = "User details")

@ApiModelProperty：用于描述一个属性或字段的信息。用法示例：@ApiModelProperty(value = "User name")

@ApiResponses：用于描述一个方法的多个响应。用法示例：@ApiResponses(value = { @ApiResponse(code = 200, message = "Success"), @ApiResponse(code = 404, message = "Not Found") })

@ApiIgnore：用于指定某个方法或类不在 Swagger 文档中显示。用法示例：@ApiIgnore

5、访问效果

网页的路径是【http://127.0.0.1:8088/MyAPI/swagger-ui.html】，拼接方法是【ip:port/path/swagger-ui.html】

这里的path是在配置文件中的服务路径【server.servlet.context-path=/MyAPI】

总结

swagger是比较常用的一种API交流插件，JAVA和.NET都用，且大多数程序员都会使用，方便大家交流API。
