springboot集成swagger

1.首先引入jar包

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.9.2</version>
</dependency>
<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>swagger-bootstrap-ui</artifactId>
    <version>1.9.2</version>
</dependency>
2.添加swagger配置类

package com.xxxx.xxx.client.config;

import springfox.documentation.service.Contact;
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.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

/**
 * @author zhangshiyu@xxx.com
 * @version 1.0
 * @date 2020/5/28 16:56
 */
@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //为当前包路径
                .apis(RequestHandlerSelectors.basePackage("com.xxxx"))
                .paths(PathSelectors.any())
                .build();
//        return new Docket(DocumentationType.SWAGGER_2).select().apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)).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("xxxxSwaggerAPI")
                //创建人
                .contact(new Contact("xxxx", "", ""))
                //版本号
                .version("1.0")
                //描述
                .description("API xxxxx")
                .build();
    }
}
3.在controller上增加注解

@Api(description = "xxxx接口",tag = "xxx")  controller类上 描述会展示在页面上

public class IQuestionManagerController {

@ApiOperation(value = "描述", notes = "说明")

@ApiImplicitParam(name = "questionDto",value = "问题idDto",paramType = "body",required = true, dataType = "QuestionDto")
方法上

public QuestionDto getQuestionByQuestionId(@RequestBody QuestionDto questionDto){

@Configuration
@EnableSwagger2 配置类上
