springboot如何整个Swagger呢？

springboot整个swagger的步骤

步骤1:引入jar包

	<!-- swagger -->
	<dependency>
		<groupId>io.springfox</groupId>
		<artifactId>springfox-swagger2</artifactId>
		<version>2.5.0</version>
	</dependency>
	<!-- swagger-ui -->
	<dependency>
		<groupId>io.springfox</groupId>
		<artifactId>springfox-swagger-ui</artifactId>
		<version>2.5.0</version>
	</dependency>

swagger2的配置文件设置

package com.java265.spring;

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.java265"))
                .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("java265", "http://www.java265.com", ""))
                //版本号
                .version("2.0")
                //描述
                .description("API 描述")
                .build();
    }
}

controller编写

package com.java265.spring.controller;

import com.java265.spring.model.User;
import com.java265.spring.service.UserService;
import io.swagger.annotations.Api;

import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiOperation;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("api")
@Api("swaggerDemoController相关的api")
public class SwaggerDemoController {

    @Autowired
    private UserService userService;

    private static final Logger logger= LoggerFactory.getLogger(SwaggerDemoController.class);


    @ApiOperation(value = "使用id查询用户信息", notes = "从数据库中查询用户信息")
    @ApiImplicitParam(name = "id", value = "UserID", paramType = "path", required = true, dataType = "Long")
    @RequestMapping(value = "/{id}", method = RequestMethod.GET)
    public User getStudent(@PathVariable Long id) {
        logger.info("查询用户信息");
        return userService.selectByPrimaryKey(id);
    }
}

使用以上方式就可实现swagger2与springboot就集成完毕了
