SpringBoot快速入门-SpringBoot 2.5.x系列的Swagger2配置

1、引入pom

<dependency>
  <groupId>io.springfox</groupId>
  <artifactId>springfox-swagger2</artifactId>
  <version>2.9.2</version>
</dependency>
<dependency>
  <groupId>io.springfox</groupId>
  <artifactId>springfox-swagger-ui</artifactId>
  <version>2.9.2</version>
</dependency>

2、添加Swagger配置类

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

/**
 * IT之美 Swagger配置类
 */
@Configuration
@EnableSwagger2
public class Swagger2 {

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .enable(true) 
                .useDefaultResponseMessages(false)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))
                .paths(PathSelectors.any())
                .build();
    }
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("swagger API文档")
                .description("接口文档")
                .version("1.0")
                .build();
    }

}

3、添加Controller

import com.itzhimei.handle.Person7;
import com.itzhimei.handle.Person8;
import io.swagger.annotations.Api;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import java.util.Arrays;

/**
 * Hello world!
 *
 */
@Api(tags = "Hello World App2")
@RestController
public class App2
{

    @Autowired
    private Person7 person7;

    @Autowired
    private Person8 person8;

    @GetMapping("/hello2")
    public String hello(@RequestParam(value = "name", defaultValue = "World") String name) {
        return String.format("Hello2 %s!", name);
    }

    @GetMapping("/getPerson7")
    public Person7 getPerson7() {
        return person7;
    }

    @GetMapping("/getPerson8")
    public Person8 getPerson8() {
        return person8;
    }

}

4、启动应用程序

5、查看文档
localhost:8081/swagger-ui.html#/

页面输出：
