Swagger
Swagger 是一个规范和完整的框架,用于生成、描述、调用和可视化 RESTful 风格的 Web 服务。
1、导入依赖
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.9.2</version>
</dependency>
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger-ui</artifactId>
<version>2.9.2</version>
</dependency>
2、SwaggerConfig配置
package com.sw.swagger.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import org.springframework.core.env.Profiles;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
import java.util.ArrayList;

@Configuration
@EnableSwagger2
public class SwaggerConfig {
//配置Swagger的Docket
@Bean
public Docket docket(Environment environment) {
//配置哪种环境下需要启用Swagger
Profiles profiles = Profiles.of("dev", "test");
//监听配置文件
boolean flag = environment.acceptsProfiles(profiles);
//链式编程
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.enable(flag) //配置是否启动Swagger,默认为true,如需关闭须手动设置为false
.select()
//RequestHandlerSelectors 配置扫描接口的方式
//basePackage() 指定要扫描的包
//any() 扫描全部
//none() 不扫描
//withClassAnnotation(Controller.class) 扫描类注解(参数是一个注解的反射对象)
//withMethodAnnotation(RequestMapping.class) 扫描方法上的注解
.apis(RequestHandlerSelectors.basePackage("com.sw.swagger.controller"))
//paths() 过滤的路径
.paths(PathSelectors.ant("/**"))
.build();
}
//配置Swagger apiInfo
private ApiInfo apiInfo(){
//作者信息
Contact contact = new Contact("suaix","http://wangchouchou.com","281463547@qq.com");
return new ApiInfo(
"Swagger StudyDemo",
"SwaggerStudy",
"1.0",
"http://wangchouchou.com",
contact,
"Apache 2.0",
"http://www.apache.org/licenses/LICENSE-2.0",
new ArrayList());
}
}
Docket配置
//配置Swagger的Docket
@Bean
public Docket docket(Environment environment) {
//配置哪种环境下需要启用Swagger
Profiles profiles = Profiles.of("dev", "test");
//监听配置文件
boolean flag = environment.acceptsProfiles(profiles);
//链式编程
return new Docket(DocumentationType.SWAGGER_2)
.apiInfo(apiInfo())
.enable(flag) //配置是否启动Swagger,默认为true,如需关闭须手动设置为false
.select()
//RequestHandlerSelectors 配置扫描接口的方式
//basePackage() 指定要扫描的包
//any() 扫描全部
//none() 不扫描
//withClassAnnotation(Controller.class) 扫描类注解(参数是一个注解的反射对象)
//withMethodAnnotation(RequestMapping.class) 扫描方法上的注解
.apis(RequestHandlerSelectors.basePackage("com.sw.swagger.controller"))
//paths() 过滤的路径
.paths(PathSelectors.ant("/**"))
.build();
}
配置什么环境下需要使用Swagger
通过监听配置文件实现
//配置那种环境下需要启用Swagger
Profiles profiles = Profiles.of("dev", "test");
//监听配置文件
boolean flag = environment.acceptsProfiles(profiles);
3、配置文档分组
.groupName("Demo")
如何配置实现多个分组?
配置多个Docket实例即可
4、实体类
package com.sw.swagger.pojo;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
/**
* @Author suaxi
* @Date 2020/12/26 14:39
*/
//@Api("用户实体类")
@ApiModel("用户实体类")
public class User {
@ApiModelProperty("用户名")
public String username;
@ApiModelProperty("密码")
public String password;
}
5、Controller
package com.sw.swagger.controller;
import com.sw.swagger.pojo.User;
import io.swagger.annotations.ApiOperation;
import io.swagger.annotations.ApiParam;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @Author suaxi
* @Date 2020/12/26 10:59
*/
@RestController
public class HelloController {
@ApiOperation("POST测试")
@PostMapping("/hello")
public String helloTest(@ApiParam("用户名") String username){
return "swagger-springboot";
}
@ApiOperation("返回User对象")
@PostMapping("/u")
public User user(){
return new User();
}
@ApiOperation("Hello控制类")
@GetMapping("/h")
public String hello(){
return "swagger-springboot";
}
}
小结:
1、通过Swagger可以给一些难以理解的属性或接口添加注释信息
2、接口文档实时更新
3、在线测试
