最简单的springboot整合swagger

1、 直入正题，导入pom依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>org.example</groupId>
    <artifactId>swagger</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <parent>
        <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.2.1.RELEASE</version>
        <relativePath/>
    </parent>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <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>

        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.26</version>
        </dependency>

    </dependencies>
</project>

2、新建启动类

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

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

3、新建用户

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.io.Serializable;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class User implements Serializable {

    private String name;

    private Integer age;

    private String addr;

}

4、新建controller

import com.xxxx.entity.User;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/admin")
public class DemoController {


    @GetMapping("getUser")
    public User getUser(User u) {
        User user = new User();
        user.setName("张三");
        user.setAge(18);
        user.setAddr("北京海淀");
        return user;
    }
}

5、新建配置类

package com.xxxx.config;

import org.apache.flink.shaded.curator.org.apache.curator.shaded.com.google.common.base.Predicates;
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.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 Swagger2Config {

    @Bean
    public Docket adminApiConfig() {
        return new Docket(DocumentationType.SWAGGER_2)
                .groupName("adminApi")
                .apiInfo(adminApiInfo())
                .select()
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo adminApiInfo() {
        return new ApiInfoBuilder()
                .title("后台管理系统-API文档")
                .description("本文档描述了后台管理系统微服务接口定义")
                .version("1.0")
                .contact(new Contact("swagger", "http://swagger.com", "XXXXX@qq.com"))
                .build();
    }

}

6、整体图

7、启动项目，web页面
