Spring Boot 集成 Swagger 文档的代码实现~

集成 Swagger

1. 在 idea 中先创建一个Spring Boot 项目

2. 修改 pom 文件

<?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>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.4.3</version>
        <relativePath/>
    </parent>

    <groupId>top.shijialeya.swagger</groupId>
    <artifactId>swagger</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <!-- 让 Maven 打包的时候忽略单元测试 -->
        <skipTests>true</skipTests>
    </properties>

    <dependencies>
        <!-- spring mvc 的集成包 -->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <!-- 导入 Swagger -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
        </dependency>
        <!-- Swagger 前端页面包 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>

    </dependencies>

</project>

Swagger 现在版本出到了 3.0.0,但在目前为止 2.9.2 版本最受欢迎使用最多,这里使用 2.9.2 版本的。

3. 编写 Swagger 配置类

package top.shijialeya.swagger.config;

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.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

/**
 * @CreateTime: 2021/2/28 9:03
 * @Description: Swagger 配置类
 */

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket createRestApi() {
        Docket docket = new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(new ApiInfoBuilder().build())
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.any())
                .build();
        return docket;
    }
}

4. 编写启动器类

package top.shijialeya.swagger;

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

@SpringBootApplication
public class SwaggerApplication {
    public static void main(String[] args) {
        SpringApplication.run(SwaggerApplication.class, args);
    }
}
  1. 修改 application.yml 文件
server:
  port: 8080
  1. 执行启动器类

  2. 在浏览器中数输入地址:http://localhost:8080/swagger-ui.html,即可打开 Swagger 页面,如下:

    到目前为止就已经集成好了!


接下来编一个控制器类来测试看看效果。
映射路径为 hello,并且该路径返回 hello world字符串。

package top.shijialeya.swagger.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class HelloController {

    @RequestMapping("hello")
    @ResponseBody
    public Object hello(){
        return "hello World";
    }
}

再来查看 swagger 页面:http://localhost:8080/swagger-ui.html,此时就多了一个 Hello Controller 栏目,打开该栏目:
