Spring集成Swagger，Java自动生成Api文档

博主很懒...

Swagger官网：http://swagger.io

GitHub地址：https://github.com/swagger-api

官方注解文档：http://docs.swagger.io/swagger-core/apidocs/index.html

Swagger-UI地址：https://github.com/swagger-api/swagger-ui

swagger最终效果图

好，开始说Spring怎么配置Swagger了

1.pom.xml引入需要的jar包

<!-- 构建Restful API 我这版本是2.6.1 -->
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>${swagger2.version}</version>
</dependency>
<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger-ui</artifactId>
    <version>${swagger2.version}</version>
</dependency>

2.扫描你的Swagger2config.java所在的包

<!-- url是你需要扫描swagger的包路径 -->
<context:component-scan  base-package="com.nickwilde.microtrain.common.config.swagger"/>

3.Swagger2config.java[类名自定义]

package com.nickwilde.microtrain.common.config.swagger2;

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;

/**
 * @author NickWilde
 * @version 2018/1/18 10:23
 * @description: Swagger2Config
 * TODO 用一句话描述
 */
@Configuration
@EnableSwagger2
public class Swagger2Config{
    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2).forCodeGeneration(true)
                .select()
                .apis(RequestHandlerSelectors.any())
                //过滤生成链接
                .paths(PathSelectors.any())
                .build()
                .apiInfo(apiInfo());
    }

    //api接口作者相关信息
    private ApiInfo apiInfo() {
        Contact contact = new Contact("NickWilde", "", "1064698801@qq.com");
        ApiInfo apiInfo = new ApiInfoBuilder()
                .license("Apache License Version 2.0")
                .title("Unexpectedly系统")
                .description("接口文档")
                .contact(contact)
                .version("1.0")
                .build();
        return apiInfo;
    }
}

4.给你的controller加上额外注解（不加也是有的）

@ApiOperation(value="根据User对象创建用户", notes="根据User对象创建用户",httpMethod = "POST") //httpMehtod如果不定义，那么swagger会有把该接口的所有请求方法都一一列举出来
@ApiImplicitParam(name = "data", value = "data描述", required = true, dataType = "UserInfo") //参数定义..类型..之类的，这是基础简单，其余的看api吧~
