作为前后端分离项目，使用api文档能够适量的解决前后端的一些沟通，同时这个swagger也可作为后端测试工具

springboot三部曲

第一，引pom.xml

 <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <swagger.version>2.6.1</swagger.version>
    </properties>
<!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger2 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>${swagger.version}</version>
        </dependency>
        <!-- https://mvnrepository.com/artifact/io.springfox/springfox-swagger-ui -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>${swagger.version}</version>
        </dependency>

加入配置类

package com.dc.dreamidlefish.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.ParameterBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.schema.ModelRef;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.service.Parameter;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

import java.util.ArrayList;
import java.util.List;

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket createRestApi(){
        ParameterBuilder builder = new ParameterBuilder();
        builder.name("Authentication").description("登陆需要验证").modelRef(new ModelRef("String")).parameterType("header").required(false).build();
        List<Parameter> parameters = new ArrayList<>();
        parameters.add(builder.build());


        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .useDefaultResponseMessages(false)
                .globalOperationParameters(parameters)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.dc.dreamidlefish.controller"))
                .paths(PathSelectors.any())
                .build();

    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("名称")
                .description("描述")
                //.termsOfServiceUrl("localhost://")
                .contact(new Contact("作者","http://www.baidu.com","[email protected]"))
                .version("0.1")
                .build();
    }
}

启动项目 输入http://localhost:项目端口号/swagger-ui.html

在使用springboot的时候 很方便 总结 就是大部分的是 引入pom 修改配置信息
加入注解 就ok
