Knife4j 接口文档 替代 老版本的Swagger-ui

中文文档：https://doc.xiaominfo.com/knife4j/documentation/get_start.html

第一步：在maven项目的pom.xml中引入Knife4j的依赖包，代码如下：

<dependency>
    <groupId>com.github.xiaoymin</groupId>
    <artifactId>knife4j-spring-boot-starter</artifactId>
    <version>2.0.7</version>
</dependency>

第二步：创建Swagger配置依赖，代码如下：

@Configuration
@EnableSwagger2WebMvc
public class Knife4jConfiguration {

    @Bean(value = "defaultApi2")
    public Docket defaultApi2() {
        Docket docket=new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(new ApiInfoBuilder()
                        //.title("swagger-bootstrap-ui-demo RESTful APIs")
                        .description("# swagger-bootstrap-ui-demo RESTful APIs")
                        .termsOfServiceUrl("http://www.xx.com/")
                        .contact("xx@qq.com")
                        .version("1.0")
                        .build())
                //分组名称
                .groupName("2.X版本")
                .select()
                //这里指定Controller扫描包路径
                .apis(RequestHandlerSelectors.basePackage("com.github.xiaoymin.knife4j.controller"))
                .paths(PathSelectors.any())
                .build();
        return docket;
    }
}

IndexController.java包含一个简单的RESTful接口,代码示例如下：

@Api(tags = "首页模块")
@RestController
public class IndexController {

    @ApiImplicitParam(name = "name",value = "姓名",required = true)
    @ApiOperation(value = "向客人问好")
    @GetMapping("/sayHi")
    public ResponseEntity<String> sayHi(@RequestParam(value = "name")String name){
        return ResponseEntity.ok("Hi:"+name);
    }
}
