官方文档：https://doc.xiaominfo.com/knife4j
版本兼容说明：https://doc.xiaominfo.com/docs/quick-start/start-knife4j-version
升级说明：https://doc.xiaominfo.com/docs/upgrading/upgrading-to-v4

版本兼容惯关系：
springboot 1.5.x~2.0.0 对应 =Knife4j 4.0.0

1.引入依赖：


    
    
      com.github.xiaoymin
      knife4j-spring-boot-starter
      2.0.9
    
注意：本次整合springboot版本为2.3.12

2.配置类

Configuration
@EnableKnife4j
@EnableSwagger2WebMvc  // 如果是 knife4j 3.x版本，则只需要去除掉该注解即可
public class SwaggerConfig {

    private String basePackage = "com.xxx.xxx.controller";

    @Bean
    public Docket createRestApi() {

        return new Docket(DocumentationType.SWAGGER_2)
                .useDefaultResponseMessages(false)
                .groupName("api")
                .enable(true)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage(basePackage)) // 基于包扫描
                .apis(RequestHandlerSelectors.withClassAnnotation(Api.class))  // 基于注解
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class)) 
                .paths(PathSelectors.any())
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("API 接口文档")
                .description("Restful API 接口文档")
                .version("1.0")
                .contact(new Contact("联系人姓名","联系人url","联系人email"))
                .termsOfServiceUrl("服务条款URL")
                .license("xxx License Version 1.0")
                .licenseUrl("http://www.xxx.xxx/licenses/LICENSE-1.0")
                .build();
    }

}


3.配置文件

# 版本建议：3.0~3.0.3   底层依赖springfox框架版本升级至3.0.3,OpenAPI规范是v3,过度版本，建议开发者不要使用
knife4j.enable=true
# 是否开启生产环境屏蔽   true:关闭swagger，false:开启swagger
# true - 设置未true报错：You do not have permission to access this page - 即生产环境禁止访问
knife4j.production=false
knife4j.setting.language=zh-CN



4.编写代码Controller

@Api(tags = "测试接口")
@Controller
@RequestMapping("/test")
public class TestController {

    @Autowired
    private RedisTemplate redisTemplate;


    @ApiOperation("set value 操作")
    @ResponseBody
    @RequestMapping(value = "/set", method = RequestMethod.POST)
    public String setVal(String key, String value) {

        redisTemplate.opsForValue().set(key, value);

        return "success set val";
    }

    @ApiOperation("get 操作")
    @ResponseBody
    @RequestMapping(value = "/get", method = RequestMethod.GET)
    public String getValue(String key) {

        String result = (String) redisTemplate.opsForValue().get(key);

        System.err.println("======> 返回结果result：" + result);

        return result;
    }


}
