swagger配置config

package com.example.config;



import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import org.springframework.core.env.Profiles;
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 java.util.ArrayList;

@Configuration
public class SwaggerConfig {
//    http://localhost:8080/swagger-ui/index.html新版路径
    @Bean//配置swagger的Docket bean实例
    public Docket docket(Environment environment){

        //设置当前要显示的Swagger环境
        Profiles of = Profiles.of("dev", "text");
        //获取当前项目环境
        boolean b = environment.acceptsProfiles(of);


        return new Docket(DocumentationType.SWAGGER_2)
                .enable(b)//是否启用swagger是false 默认true
                .apiInfo(apiInfo())
                .select()
                //RequestHandlerSelectors配置要扫描接口的方式
                //any()扫描全部
                //none()不扫描
                //withClassAnnotation()扫描类上的注解,参数是一个注解的反射对象
                //withMethodAnnotation()扫描方法上的注解
                //basePackage()指定要扫描那个包
                .apis(RequestHandlerSelectors.basePackage("com.example.controller"))
                //.paths(PathSelectors.ant("/hello/**"))//过滤什么路径
                .build()
                ;
    }


    //配置swagger的一些信息 作者信息
    public ApiInfo apiInfo(){
        Contact contact = new Contact("鲁家见","","482475181@qq.com");
        return new ApiInfo(
                "L的swagger的API文档",
                "学生管理项目文档",
                "1.0",
                "urn:tos",
                contact,
                "Apache 2.0",
                "http://www.apache.org/licenses/LICENSE-2.0",
                new ArrayList<>());
    }

}

controller普通接口

package com.example.controller;


import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class HelloController {
    @GetMapping("/hello")
    public String Hello(){
        return "hello";
    }
    @PostMapping("/hello1")
    public String Hello1(String name ,String password){
        return "你输入的用户名和密码分别是"+name+":"+password;
    }
}

运行主类

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;

@EnableWebMvc//一定记住启动类加入@EnableWebMvc注解，不然会空指针异常,用Swagger
@SpringBootApplication
public class SpringbootSwaggerApplication {

    public static void main(String[] args) {
        SpringApplication.run(SpringbootSwaggerApplication.class, args);
    }

}

yml设置项目环境

yml

spring:
  profiles:
    active: dev

yml-pev

server:
  port: 8081

yml-pvo
