一、加入依赖
io.springfox springfox-swagger2 2.7.0 io.springfox springfox-swagger-ui 2.7.0
二、创建Swagger2配置类
package com.sxdx.oa_service.config;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.web.bind.annotation.RestController;import springfox.documentation.builders.ApiInfoBuilder;import springfox.documentation.builders.PathSelectors;import springfox.documentation.builders.RequestHandlerSelectors;import springfox.documentation.service.ApiInfo;import springfox.documentation.spi.DocumentationType;import springfox.documentation.spring.web.plugins.Docket;import springfox.documentation.swagger2.annotations.EnableSwagger2;@Configuration@EnableSwagger2public class SwaggerConfiguration { @Bean public Docket createRestApi() { return new Docket(DocumentationType.SWAGGER_2) .apiInfo(apiInfo()) .select() //.apis(RequestHandlerSelectors.basePackage("com.sxdx.oa_service"))//配置需要生成文档的扫码路径 .apis(RequestHandlerSelectors.withClassAnnotation(RestController.class))//配置需要生成文档的类型,此处为所有添加了@RestController注解的类 .paths(PathSelectors.any()) .build(); } private ApiInfo apiInfo() { return new ApiInfoBuilder() .title("RESTful APIs") .description("oa_frame 接口文档") //.termsOfServiceUrl("http://easonjim.com/") .contact("高一鹏") .version("1.0") .build(); }}
三、代码示例
package com.sxdx.oa_service.springCacheTest.controller;import com.sxdx.oa_service.bootTest.bean.JsonResult;import com.sxdx.oa_service.springCacheTest.model.Department;import com.sxdx.oa_service.springCacheTest.service.CacheTestService;import io.swagger.annotations.Api;import io.swagger.annotations.ApiOperation;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.http.ResponseEntity;import org.springframework.web.bind.annotation.*;@RestController@Api(value = "缓存练习接口",tags = {"缓存练习接口"},description="用于练习spring缓存及redis",hidden = false)public class CacheTestController { @Autowired private CacheTestService cacheTestService; @ApiOperation( value = "通过id查询部门信息", notes="通过id查询部门信息") @GetMapping(value = "selectDeptById/{id}") public ResponseEntityselectByPrimaryKey(@PathVariable Integer id){ JsonResult r = new JsonResult(); try { Department department = cacheTestService.selectByPrimaryKey(id); r.setResult(department); r.setStatus("success"); } catch (Exception e) { r.setResult(e.getClass().getName() + ":" + e.getMessage()); r.setStatus("failure"); e.printStackTrace(); } return ResponseEntity.ok(r); } @ApiOperation(value = "修改部门信息", notes="修改部门信息") @PostMapping(value = "updateByPrimaryKeySelective") public ResponseEntity updateByPrimaryKeySelective(@RequestBody Department dept){ JsonResult r = new JsonResult(); try { Department department = cacheTestService.updateByPrimaryKeySelective(dept); r.setResult(department); r.setStatus("success"); } catch (Exception e) { r.setResult(e.getClass().getName() + ":" + e.getMessage()); r.setStatus("failure"); e.printStackTrace(); } return ResponseEntity.ok(r); } @ApiOperation(value = "通过id 删除部门", notes="通过id 删除部门") @GetMapping (value = "deleteDeptById/{id}") public ResponseEntity updateByPrimaryKeySelective(@PathVariable Integer id){ JsonResult r = new JsonResult(); try { int num = cacheTestService.deleteByPrimaryKey(id); r.setResult("已删除"); r.setStatus("success"); } catch (Exception e) { r.setResult(e.getClass().getName() + ":" + e.getMessage()); r.setStatus("failure"); e.printStackTrace(); } return ResponseEntity.ok(r); }}
四、生成的文档效果(http://127.0.0.1:8080/oaframe/swagger-ui.html)
五、各个注解的介绍(转载自https://www.cnblogs.com/hyl8218/p/8520994.html)
常用到的注解有:
- Api
- ApiModel
- ApiModelProperty
- ApiOperation
- ApiParam
- ApiResponse
- ApiResponses
- ResponseHeader
1. api标记
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")
与Controller注解并列使用。 属性配置:
属性名称 | 备注 |
---|---|
value | url的路径值 |
tags | 如果设置这个值、value的值会被覆盖 |
description | 对api资源的描述 |
basePath | 基本路径可以不配置 |
position | 如果配置多个Api 想改变显示的顺序位置 |
produces | For example, "application/json, application/xml" |
consumes | For example, "application/json, application/xml" |
protocols | Possible values: http, https, ws, wss. |
authorizations | 高级特性认证时配置 |
hidden | 配置为true 将在文档中隐藏 |
在SpringMvc中的配置如下:
@Controller@RequestMapping(value = "/api/pet", produces = {APPLICATION_JSON_VALUE, APPLICATION_XML_VALUE})@Api(value = "/pet", description = "Operations about pets") public class PetController { }
2. ApiOperation标记
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"})
与Controller中的方法并列使用。
属性配置:属性名称 | 备注 |
---|---|
value | url的路径值 |
tags | 如果设置这个值、value的值会被覆盖 |
description | 对api资源的描述 |
basePath | 基本路径可以不配置 |
position | 如果配置多个Api 想改变显示的顺序位置 |
produces | For example, "application/json, application/xml" |
consumes | For example, "application/json, application/xml" |
protocols | Possible values: http, https, ws, wss. |
authorizations | 高级特性认证时配置 |
hidden | 配置为true 将在文档中隐藏 |
response | 返回的对象 |
responseContainer | 这些对象是有效的 "List", "Set" or "Map".,其他无效 |
httpMethod | "GET", "HEAD", "POST", "PUT", "DELETE", "OPTIONS" and "PATCH" |
code | http的状态码 默认 200 |
extensions | 扩展属性 |
在SpringMvc中的配置如下:
@RequestMapping(value = "/order/{orderId}", method = GET) @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.class, tags = { "Pet Store" }) public ResponseEntitygetOrderById(@PathVariable("orderId") String orderId) throws NotFoundException { Order order = storeData.get(Long.valueOf(orderId)); if (null != order) { return ok(order); } else { throw new NotFoundException(404, "Order not found"); } }
3. ApiParam标记
ApiParam请求属性,使用方式:
public ResponseEntitycreateUser(@RequestBody @ApiParam(value = "Created user object", required = true) User user)
与Controller中的方法并列使用。
属性配置:
属性名称 | 备注 |
---|---|
name | 属性名称 |
value | 属性值 |
defaultValue | 默认属性值 |
allowableValues | 可以不配置 |
required | 是否属性必填 |
access | 不过多描述 |
allowMultiple | 默认为false |
hidden | 隐藏该属性 |
example | 举例子 |
在SpringMvc中的配置如下:
public ResponseEntitygetOrderById( @ApiParam(value = "ID of pet that needs to be fetched", allowableValues = "range[1,5]", required = true) @PathVariable("orderId") String orderId)
4. ApiResponse
ApiResponse:响应配置,使用方式:
@ApiResponse(code = 400, message = "Invalid user supplied")
与Controller中的方法并列使用。 属性配置:
属性名称 | 备注 |
---|---|
code | http的状态码 |
message | 描述 |
response | 默认响应类 Void |
reference | 参考ApiOperation中配置 |
responseHeaders | 参考 ResponseHeader 属性配置说明 |
responseContainer | 参考ApiOperation中配置 |
在SpringMvc中的配置如下:
@RequestMapping(value = "/order", method = POST) @ApiOperation(value = "Place an order for a pet", response = Order.class) @ApiResponses({ @ApiResponse(code = 400, message = "Invalid Order") }) public ResponseEntityplaceOrder( @ApiParam(value = "order placed for purchasing the pet", required = true) Order order) { storeData.add(order); return ok(""); }
5. ApiResponses
ApiResponses:响应集配置,使用方式:
@ApiResponses({ @ApiResponse(code = 400, message = "Invalid Order") })
与Controller中的方法并列使用。 属性配置:
属性名称 | 备注 |
---|---|
value | 多个ApiResponse配置 |
在SpringMvc中的配置如下:
@RequestMapping(value = "/order", method = POST) @ApiOperation(value = "Place an order for a pet", response = Order.class) @ApiResponses({ @ApiResponse(code = 400, message = "Invalid Order") }) public ResponseEntityplaceOrder( @ApiParam(value = "order placed for purchasing the pet", required = true) Order order) { storeData.add(order); return ok(""); }
6. ResponseHeader
响应头设置,使用方法
@ResponseHeader(name="head1",description="response head conf")
与Controller中的方法并列使用。 属性配置:
属性名称 | 备注 |
---|---|
name | 响应头名称 |
description | 头描述 |
response | 默认响应类 Void |
responseContainer | 参考ApiOperation中配置 |
在SpringMvc中的配置如下:
@ApiModel(description = "群组")
7. 其他
- @ApiImplicitParams:用在方法上包含一组参数说明;
- @ApiImplicitParam:用在@ApiImplicitParams注解中,指定一个请求参数的各个方面
- paramType:参数放在哪个地方
- name:参数代表的含义
- value:参数名称
- dataType: 参数类型,有String/int,无用
- required : 是否必要
- defaultValue:参数的默认值
- @ApiResponses:用于表示一组响应;
- @ApiResponse:用在@ApiResponses中,一般用于表达一个错误的响应信息;
- code: 响应码(int型),可自定义
- message:状态码对应的响应信息
- @ApiModel:描述一个Model的信息(这种一般用在post创建的时候,使用@RequestBody这样的场景,请求参数无法使用@ApiImplicitParam注解进行描述的时候;
- @ApiModelProperty:描述一个model的属性。
