springboot集成swagger

一、加入依赖

<dependency>
                <groupId>io.springfox</groupId>
                <artifactId>springfox-swagger2</artifactId>
                <version>2.7.0</version>
            </dependency>
            <dependency>
                <groupId>io.springfox</groupId>
                <artifactId>springfox-swagger-ui</artifactId>
                <version>2.7.0</version>
            </dependency>

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
@EnableSwagger2
public 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 ResponseEntity<JsonResult> selectByPrimaryKey(@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<JsonResult> 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<JsonResult> 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 ResponseEntity<Order> getOrderById(@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 ResponseEntity<User> createUser(@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 ResponseEntity<Order> getOrderById(
      @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 ResponseEntity<String> placeOrder(
      @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 ResponseEntity<String> placeOrder(
      @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。
