knife4j只用此插件的最简洁开发方式

一、POM添加

在pom文件里添加包

1  
2 <dependency> 
3 <groupId>com.github.xiaoymingroupId> 
4 <artifactId>knife4j-spring-boot-starterartifactId> <version>1.9.6version> 
5 dependency>

View Code

二、配置添加，相当于添加

 1 package com.mrliu.undertow.conf;
 2 
 3 import com.github.xiaoymin.knife4j.spring.annotations.EnableSwaggerBootstrapUi;
 4 import org.springframework.context.annotation.Bean;
 5 import org.springframework.context.annotation.Configuration;
 6 import springfox.documentation.builders.ApiInfoBuilder;
 7 import springfox.documentation.builders.PathSelectors;
 8 import springfox.documentation.builders.RequestHandlerSelectors;
 9 import springfox.documentation.service.ApiInfo;
10 import springfox.documentation.service.Contact;
11 import springfox.documentation.spi.DocumentationType;
12 import springfox.documentation.spring.web.plugins.Docket;
13 import springfox.documentation.swagger2.annotations.EnableSwagger2;
14 
15 /**
16  * @author liuyang
17  */
18 @Configuration
19 @EnableSwagger2
20 @EnableSwaggerBootstrapUi
21 public class Swagger2Config {
22 
23     /**
24      * 创建连接的包信息
25      * 

26      * 配置统一返回的controller路径RequestHandlerSelectors.basePackage
27      *
28      * @return 返回创建状况
29      */
30     @Bean
31     public Docket createRestApi() {
32         return new Docket(DocumentationType.SWAGGER_2)
33                 .useDefaultResponseMessages(false)
34                 .apiInfo(apiInfo())
35                 .select()
36                 .apis(RequestHandlerSelectors.basePackage("com.mrliu.undertow.controller"))
37                 .paths(PathSelectors.any())
38                 .build();
39 
40     }
41 
42 
43     /**
44      * 设置文档信息主页的内容说明
45      *
46      * @return 文档信息
47      */
48     private ApiInfo apiInfo() {
49         return new ApiInfoBuilder()
50                 .title("Project textBook API ")
51                 .description("服务接口")
52                 .termsOfServiceUrl("http://localhost:8001/")
53                 .contact(new Contact("Mr Liu", "http://localhost:8999/", "[email protected]"))
54                 .license("what")
55                 .version("1.0")
56                 .build();
57     }
58 
59 }

View Code

apiInfo()设置后会改变如图

三、bean实体类添加

 1 /**
 2  * @author Administrator
 3  */
 4 @ApiModel("用户对象")
 5 @Data
 6 public class UserVO {
 7 
 8     @ApiModelProperty(required = true, notes = "用户名", example = "blues")
 9     private String name;
10 
11     @ApiModelProperty(required = true, notes = "用户返回消息", example = "hello world")
12     private String words;
13 
14 
15     public UserVO(String name, String words) {
16         this.name = name;
17         this.words = words;
18     }
19 }

View Code

主要是添加注解

@ApiModel("用户对象") -----实体类注解添加 添加后结果如图所示:

@ApiModelProperty(required = true, notes = "用户名", example = "blues") 字段注解添加 添加后结果如图所示:

四、Controller添加

• 1、GET方式访问
  
  

   1 package com.mrliu.undertow.controller;
   2 
   3 import com.mrliu.undertow.base.Results;
   4 import com.mrliu.undertow.pojo.UserVO;
   5 import io.swagger.annotations.*;
   6 import org.springframework.web.bind.annotation.GetMapping;
   7 import org.springframework.web.bind.annotation.PathVariable;
   8 import org.springframework.web.bind.annotation.RequestMapping;
   9 import org.springframework.web.bind.annotation.RestController;
  10 
  11 import javax.servlet.http.HttpServletRequest;
  12 import javax.servlet.http.HttpServletResponse;
  13 import java.io.IOException;
  14 
  15 /**
  16  * @author Administrator
  17  */
  18 @Api(tags = "HELLO CONTROLLER 测试功能接口")
  19 @RestController
  20 public class HelloController {
  21 
  22 
  23     @ApiImplicitParams({
  24             @ApiImplicitParam(name = "name",value = "用户名称",required = true,dataType = "String",paramType = "path",example = "blues")
  25     })
  26     @ApiResponses(value = {
  27             @ApiResponse(code = 200, message = "接口返回成功状态"),
  28             @ApiResponse(code = 500, message = "接口返回未知错误，请联系开发人员调试")
  29     })
  30     @ApiOperation(value = "Hello 测试接口", notes = "访问此接口，返回hello语句，测试接口")
  31     @GetMapping("hello/{name}")
  32     public Results hello(@PathVariable String name){
  33         UserVO userVO = new UserVO(name,"hello " + name);
  34         Results results = new Results<>(200,"SUCCESS", userVO);
  35         return results;
  36     }
  37 }

  View Code
   界面生成:

• 2、POST方式访问

 1 @Api(tags = "HELLO CONTROLLER 测试功能接口")
 2 @RestController
 3 public class HelloController {
 4 
 5 
 6     @ApiImplicitParams({
 7             @ApiImplicitParam(name = "name",value = "用户名称",required = true,dataType = "String",paramType = "path",example = "blues")
 8     })
 9     @ApiResponses(value = {
10             @ApiResponse(code = 200, message = "接口返回成功状态"),
11             @ApiResponse(code = 500, message = "接口返回未知错误，请联系开发人员调试")
12     })
13     @ApiOperation(value = "Hello 测试接口", notes = "访问此接口，返回hello语句，测试接口")
14     @PostMapping("hello/{name}")
15     public Results hello(@RequestBody UserVO userVO){
16         Results results = new Results<>(200,"SUCCESS", userVO);
17         return results;
18     }
19 }

View Code

五、访问URL

http://localhost:7788/doc.html

六、兼容swagger-ui访问

http://localhost:7788/swagger-ui.html

七、测试

填入参数

对象请求访问

八、API文档复制

复制后可生成markdow文档，使用showdoc，即可翻译成文档，下载html、PDF、word等格式
