1、是一款让你更好的书写API文档的规范且完整框架。
2、提供描述、生产、消费和可视化RESTful Web Service。
3、是由庞大工具集合支撑的形式化规范。这个集合涵盖了从终端用户接口、底层代码库到商业API管理的方方面面。
1、在pom.xml文件中添加第三方swagger依赖()
com.spring4all
swagger-spring-boot-starter
1.7.0.RELEASE
2、在Spring Boot项目的启动类上添加@EnableSwagger2Doc注解,就可以直接使用啦。
3、https://github.com/SpringForAll/spring-boot-starter-swagger这是GitHub上这个swagger依赖实现的项目,里面有详细的讲解。
io.springfox
springfox-swagger2
2.7.0
io.springfox
springfox-swagger-ui
2.7.0
需要特别注意的是swagger scan base package,这是扫描注解的配置,即你的API接口位置。

//本controller的功能描述
@Api(value = "pet", description = "the pet API")
public interface PetApi {
//option的value的内容是这个method的描述,notes是详细描述,response是最终返回的json model。其他可以忽略
@ApiOperation(value = "Add a new pet to the store", notes = "", response = Void.class, authorizations = {
@Authorization(value = "petstore_auth", scopes = {
@AuthorizationScope(scope = "write:pets", description = "modify pets in your account"),
@AuthorizationScope(scope = "read:pets", description = "read your pets")
})
}, tags={ "pet", })
//这里是显示你可能返回的http状态,以及原因。比如404 not found, 303 see other
@ApiResponses(value = {
@ApiResponse(code = 405, message = "Invalid input", response = Void.class) })
@RequestMapping(value = "/pet",
produces = { "application/xml", "application/json" },
consumes = { "application/json", "application/xml" },
method = RequestMethod.POST)
ResponseEntity addPet(
//这里是针对每个参数的描述
@ApiParam(value = "Pet object that needs to be added to the store" ,required=true ) @RequestBody Pet body);
在配置文件中,application.yml中声明:
springfox.documentation.swagger.v2.path: /api-docs
这个path就是json的访问request mapping.可以自定义,防止与自身代码冲突。
API doc的显示路由是:http://localhost:8080/swagger-ui.html
如果项目是一个webservice,通常设定home / 指向这里:
@Controller
public class HomeController {
@RequestMapping(value = "/swagger")
public String index() {
System.out.println("swagger-ui.html");
return "redirect:swagger-ui.html";
}
}
Api 用在类上,说明该类的作用。可以标记一个Controller类做为swagger 文档资源,使用方式:
@Api(value = "/user", description = "Operations about user")
ApiOperation:用在方法上,说明方法的作用,每一个url资源的定义,使用方式:
@ApiOperation(
value = "Find purchase order by ID",
notes = "For valid response try integer IDs with value <= 5 or > 10. Other values will generated exceptions",
response = Order,
tags = {"Pet Store"})
ApiParam请求属性,使用方式:
public ResponseEntity createUser(@RequestBody @ApiParam(value = "Created user object", required = true) User user)
ApiResponse:响应配置,使用方式:
@ApiResponse(code = 400, message = "Invalid user supplied")
ApiResponses:响应集配置,使用方式:
@ApiResponses({ @ApiResponse(code = 400, message = "Invalid Order") })
响应头设置,使用方法
@ResponseHeader(name="head1",description="response head conf")
