Swagger2 的作用

  1. 随项目自动生成强大RESTful API文档，减少工作量
  2. API文档与代码整合在一起，便于同步更新API说明
  3. 页面测试功能来调试每个RESTful API

修改pom文件，添加swagger2的相关依赖

<dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.7.0</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.7.0</version>
        </dependency>

新建一个swagger的配置类SwaggerConfig.java

package com.caojiulu.utils;

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 SwaggerConfig {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.caojiulu"))// 指定扫描包下面的注解
                .paths(PathSelectors.any())
                .build();
    }
    // 创建api的基本信息
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("集成Swagger2构建RESTful APIs")
                .description("集成Swagger2构建RESTful APIs")
                .termsOfServiceUrl("http://www.xiangxueketang.cn/")
                .contact(new Contact("enjoy","com.caojiulu","caojiulu@caojiulu.cn"))
                .version("1.0.0")
                .build();
    }
}
