SpringBoot配置Swagger实例（POST接收json参数）

工程目录结构：

首先，引入jar包，只需要以下两个即可

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.4.</version>
</dependency>

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>2.4.</version>
</dependency>

1、Swagger配置类

package com.mark.swagger;

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 Swagger2 {
//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()
                //为当前包路径
                .apis(RequestHandlerSelectors.basePackage("com.mark"))
                .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("WangXiaodong", "http://www.baidu.com", ""))
                //版本号
                .version("1.0")
                //描述
                .description("API 描述")
                .build();
    }

}

注意修改：basePackage("接口所在controller的包路径")

2、实体类

接口接收入参为json串，需由实体类转化为对应key-value

package com.mark.swagger;

public class User {

    private String name;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "User [name=" + name + "]";
    }

}

3、接口所在Controller

package com.mark.swagger;

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.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;

@RestController
@RequestMapping("/hello")
@Api(value = "/hello")
public class SwagController {

    @ApiOperation(value = "查询用户", notes = "查询用户")
    @ApiImplicitParams({@ApiImplicitParam(name = "name", value = "姓名", required = true, dataType = "String"),
    })
    @RequestMapping(value = "/getName",method=RequestMethod.POST)
    @ResponseBody
    public User getName(@RequestBody User name) {
        System.out.println(name.toString());
        return name;
    }

}

通过@RequestBody注解，将接收到的json参数，转化为实体类User对应的值

4、SpringBoot启动类

虽然大家都知道，还是来一个吧

package com.mark;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

 测试

输入地址：localhost:8080/swagger-ui.html

如下所示：出现刚才写的接口

点击SHow/Hide

1、/hello/getName：路径

2、Model：入参json对应的model，就是上面的User

3、填写要传入的参数（json格式）

传入参数：

{
  "name": "WangXiaodong"
}

测试结果：
