SpringBoto集成Knife4j

添加maven，可以去官方找最新的

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

创建Swagger配置依赖

@Configuration
@EnableSwagger2WebMvc
public class Knife4jConfigruation {

    @Bean(value = "defaultApi2")
    public Docket defaultApi2(){
        Docket docket = new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(new ApiInfoBuilder()
                        .title("demo1")         //标题
                        .description("# swagger-bootstrap-ui-demo RESTful APIs")    //描述
                        .termsOfServiceUrl("http://www.xx.com")
                        .version("1.0")
                        .build())
                //分组名称
                .groupName("2.x版本")
                .select()
                //这里指包的路径
                .apis(RequestHandlerSelectors.basePackage("com.example.demo.cotroller"))
                .paths(PathSelectors.any())
                .build();

        return docket;
    }
}

整个工程

DomeController和TextController测试接口

/**
 * 测试类
 */
@Api(tags = "首页模块")
@RestController
public class TextController {
    /**
     * 首页
     * @return String
     */
    @ApiImplicitParam(name = "name", value = "姓名", required = true)
    @ApiOperation("向客人问好")
    @PostMapping("index")
    public String index(String name){
        if(!name.equals(""))
        return "holle "+name;
        return "holle world";
    }
}

/**
 * 测试
 */
@Api(tags = "测试")
@RestController
public class DomeController {
    /**
     *
     * @param num
     * @return  String
     */
    @ApiImplicitParam(name = "num",value = "数字",required = true)
    @ApiOperation("像世界问好")
    @GetMapping("show")
    public String show(int num){
        return num+"你好 欢迎使用Knife4j";
    }
}

然后启动spring boot工程 访问地址:http://localhost:8080/doc.html

这样就ok了
