SpringBoot引入Swagger3
Swagger3介绍
开发中有很多接口的开发,接口需要配合完整的接口文档才更方便沟通、使用,Swagger是一个用于自动生成在线接口文档的框架,并可在线测试接口,可以很好的跟Spring结合,只需要添加少量的代码和注解即可,而且在接口变动的同时,即可同步修改接口文档,不用再手动维护接口文档。Swagger3是17年推出的最新版本,相比于Swagger2配置更少,使用更方便
开发环境
JDK 11
SpringBoot 2.5.4
添加Maven依赖
io.springfox
springfox-boot-starter
3.0.0
添加Swagger配置类
package com.springboot.admin.Swagger;
import io.swagger.annotations.ApiOperation;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.oas.annotations.EnableOpenApi;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
@EnableOpenApi
@Configuration
public class SwaggerConfig {
@Bean
public Docket createRestApi() {
return new Docket(DocumentationType.OAS_30)
.apiInfo(apiInfo())
.select()
//设置通过什么方式定位需要自动生成文档的接口,这里定位方法上的@ApiOperation注解
.apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
//接口URI路径设置,any是全路径,也可以通过PathSelectors.regex()正则匹配
.paths(PathSelectors.any())
.build();
}
private ApiInfo apiInfo() {
return new ApiInfoBuilder()
.title("Swagger3接口文档")
.version("1.0")
.description("API 描述")
.build();
}
}
使用Swagger
- 在接口类上添加@Api(tags = "操作接口"),tags的值是该类的作用,在文档页面会显示,value不会显示
- 在需要生成文档的接口上添加注解@ApiOperation
- 对请求参数添加@ApiParam
示例如下
package com.springboot.admin.controller;
import com.springboot.admin.jwt.JwtAuthService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.system.ApplicationHome;
import org.springframework.security.access.annotation.Secured;
import org.springframework.security.access.prepost.PreAuthorize;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
@Api(tags = "测试接口")
public class TestController {
@Autowired
JwtAuthService jwtAuthService;
@GetMapping("/test")
@ApiOperation(value="测试接口1", notes="获取当前目录")
@ApiImplicitParams({
@ApiImplicitParam(name = "name", value = "名字", dataType = "String", required = true),
@ApiImplicitParam(name = "typeId", value = "类型ID", dataType = "Long", required = true)
})
public String test() throws Exception {
// 获取当前目录
ApplicationHome ah = new ApplicationHome(JwtAuthService.class);
String docStorePath = ah.getSource().getParentFile().toString();
System.out.println(docStorePath);
return "hello world";
}
@GetMapping("/a")
@Secured("ROLE_abc")
@ApiOperation(value="测试接口2", notes="测试权限接口")
public String a() {
return "hello a api";
}
@GetMapping("/b")
@PreAuthorize("hasRole('abcc')")
@ApiOperation(value = "测试接口3",notes="测试权限接口333")
public String b() {
return "hello b api";
}
}
查看效果:
启动服务后,就可以查看在线文档了,本地服务的地址是http://localhost:8080/swagger-ui/index.html,还可以通过Try it out 来测试。
如果应用有带上下文,那么地址地址也要加上上下文,比如:http://localhost:8091/bootService/swagger-ui/index.html
注意:
如果应用有引入security,那么需要将swagger相关资源放行:
// 放行swagger3相关资源
.antMatchers("/swagger-ui/**").permitAll()
.antMatchers("/webjars/**").permitAll()
.antMatchers("/v3/**").permitAll()
.antMatchers("/swagger-resources/**").permitAll()
