本文主要是介绍swagger接口文档工具，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
（1）导入依赖
<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.9.2</version>
</dependency>
<dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.9.2</version>
</dependency>
``
（2） swagger常用注解
@Api用在请求的类上，例如Controller，表示对类的说明
@ApiModel用在类上，通常是实体类，表示一个返回响应数据的信息
@ApiModelProperty 用在属性上，描述响应类的属性
@ApiOperation 用在请求的方法上，说明方法的用途、作用
@ApiImplicitParams 用在请求的方法上，表示一组参数说明
@ApiImplicitParam 用在@ApiImplicitParams注解中，指定一个请求参数的各个方面第一步：创建maven工程swagger_demo并配置pom.xml文件```java
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><parent><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-parent</artifactId><version>2.2.2.RELEASE</version><relativePath/></parent><groupId>cn.swagger</groupId><artifactId>swagger_demo</artifactId><version>0.0.1-SNAPSHOT</version><name>swagger_demo</name><description>Demo project for Spring Boot</description><properties><java.version>1.8</java.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger-ui</artifactId><version>2.9.2</version></dependency><dependency><groupId>io.springfox</groupId><artifactId>springfox-swagger2</artifactId><version>2.9.2</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId></dependency></dependencies>
</project>
第二步：创建application.yml文件
server:port: 9000
第三步： 创建实体类User和Menu
@Data
@ApiModel(description = "用户实体")
public class User {@ApiModelProperty(value = "主键")private int id;@ApiModelProperty(value = "姓名")private String name;@ApiModelProperty(value = "年龄")private int age;@ApiModelProperty(value = "地址")private String address;
}
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
@Data
@ApiModel(description = “菜单实体”)
public class Menu {
@ApiModelProperty(value = “主键”)
private int id;
@ApiModelProperty(value = “菜单名称”)
private String name;
}
第四步：创建UserController和MenuController第四步：创建UserController和MenuController```java
@RestController
@RequestMapping("/user")
@Api(tags = "用户控制器")
public class UserController {@GetMapping("/getUsers")@ApiOperation(value = "查询所有用户", notes = "查询所有用户信息")public List<User> getAllUsers(){User user = new User();user.setId(100);user.setName("itcast");user.setAge(20);user.setAddress("bj");List<User> list = new ArrayList<>();list.add(user);return list;}@PostMapping("/save")@ApiOperation(value = "新增用户", notes = "新增用户信息")public String save(@RequestBody User user){return "OK";}@PutMapping("/update")@ApiOperation(value = "修改用户", notes = "修改用户信息")public String update(@RequestBody User user){return "OK";}@DeleteMapping("/delete")@ApiOperation(value = "删除用户", notes = "删除用户信息")public String delete(int id){return "OK";}@ApiImplicitParams({@ApiImplicitParam(name = "pageNum", value = "页码", required = true, type = "Integer"),@ApiImplicitParam(name = "pageSize", value = "每页条数", required = true, type = "Integer"),})@ApiOperation(value = "分页查询用户信息")@GetMapping(value = "page/{pageNum}/{pageSize}")public String findByPage(@PathVariable Integer pageNum,@PathVariable Integer pageSize) {return "OK";}
}
@RestController
@RequestMapping("/menu")
@Api(tags = "菜单控制器")
public class MenuController {@GetMapping("/getMenus")@ApiOperation(value = "查询所有菜单", notes = "查询所有菜单信息")public List<Menu> getMenus(){Menu menu = new Menu();menu.setId(100);menu.setName("itcast");List<Menu> list = new ArrayList<>();list.add(menu);return list;}@PostMapping("/save")@ApiOperation(value = "新增菜单", notes = "新增菜单信息")public String save(@RequestBody Menu menu){return "OK";}@PutMapping("/update")@ApiOperation(value = "修改菜单", notes = "修改菜单信息")public String update(@RequestBody Menu menu){return "OK";}@DeleteMapping("/delete")@ApiOperation(value = "删除菜单", notes = "删除菜单信息")public String delete(int id){return "OK";}@ApiImplicitParams({@ApiImplicitParam(name = "pageNum", value = "页码", required = true, type = "Integer"),@ApiImplicitParam(name = "pageSize", value = "每页条数", required = true, type = "Integer"),})@ApiOperation(value = "分页查询菜单信息")@GetMapping(value = "page/{pageNum}/{pageSize}")public String findByPage(@PathVariable Integer pageNum,@PathVariable Integer pageSize) {return "OK";}
}
第五步：创建配置类SwaggerAutoConfiguration
@Configuration
@EnableSwagger2
public class SwaggerAutoConfiguration {@Beanpublic Docket createRestApi1() {Docket docket = new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).groupName("用户接口组").select()//为当前包路径.apis(RequestHandlerSelectors.basePackage("cn.swagger.controller.user")).build();return docket;}@Beanpublic Docket createRestApi2() {Docket docket = new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo()).groupName("菜单接口组").select()//为当前包路径.apis(RequestHandlerSelectors.basePackage("cn.swagger.controller.menu")).build();return docket;}//构建 api文档的详细信息private ApiInfo apiInfo() {return new ApiInfoBuilder()//页面标题.title("API接口文档")//创建人.contact(new Contact("百度", "http://www.baidu.com", ""))//版本号.version("1.0")//描述.description("API 描述").build();}
}
第六步：创建启动类SwaggerDemoApplication
@SpringBootApplication
public class SwaggerDemoApplication {public static void main(String[] args) {SpringApplication.run(SwaggerDemoApplication.class, args);}
}
