二、SpringBoot 整合 swagger2 (swagger2 版本 2.8.0)

（一）添加依赖

		<swagger.version>2.8.0</swagger.version>

		<!-- swagger2  restful api 文档  start -->
		<dependency>
			<groupId>io.springfox</groupId>
			<artifactId>springfox-swagger2</artifactId>
			<version>${swagger.version}</version>
		</dependency>
		<dependency>
			<groupId>io.springfox</groupId>
			<artifactId>springfox-swagger-ui</artifactId>
			<version>${swagger.version}</version>
		</dependency>
		<!-- swagger2  restful api 文档  end -->

（二）swagger2的配置启动类

package com.tushuo.config;

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;

/**
 * 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
 * @author 咸鱼

 */
@Configuration
@EnableSwagger2
public class SwaggerConfiguration {
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                //api所在包路径（这个包指的是我们在哪些类中使用swagger2来测试）
                .apis(RequestHandlerSelectors.basePackage("com.tushuo.controller"))
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                //页面标题
                .title("api文档")
                //描述
                .description("restful 风格接口")
                //创建人
                .contact(new Contact("咸鱼", "https://blog.****.net", "[email protected]"))
                //版本号
                .version("1.0")
                .build();
    }
}

（三）使用案例

1、添加相关注解

@RestController
@RequiredArgsConstructor(onConstructor = @__(@Autowired))
@Api("测试 UserController 相关api")
public class UserController {

    private final UserService userService;

    @ApiOperation(value = "保存用户", notes = "保存用户")
    @ApiImplicitParam(name = "user", value = "User", required = true, dataType = "User")
    @PostMapping("/user")
    public boolean addUser(@RequestBody User user) {
        return userService.save(user);
    }
}

2、访问http://localhost:8080/swagger-ui.html
