注解解释

参数详解可参考：https://blog.csdn.net/jiangyu1013/article/details/83107255

主要参数：
@Api：修饰整个类，描述Controller的作用
　　例如：@Api(value="书籍controller",tags={"书籍操作接口"})


@ApiOperation：描述一个类的一个方法，或者说一个接口
　　例如
　　@ApiOperation(value="form格式提交创建图书", notes="form格式提交创建图书(哈哈哈)")

    @ApiImplicitParams：用在请求的方法上，表示一组参数说明
    @ApiImplicitParam：用在@ApiImplicitParams注解中，指定一个请求参数的各个方面
        name：参数名
        value：参数的汉字说明、解释
        required：参数是否必须传
        paramType：参数放在哪个地方
            · header --> 请求参数的获取：@RequestHeader
            · query --> 请求参数的获取：@RequestParam
            · path（用于restful接口）--> 请求参数的获取：@PathVariable
            · body（不常用）
            · form（不常用）    
        dataType：参数类型，默认String，其它值dataType="Integer"       
        defaultValue：参数的默认值
　　例如：
　　@ApiImplicitParams({
            @ApiImplicitParam(name = "name", value = "名称", required = true, dataType = "String",paramType = "query"),
            @ApiImplicitParam(name = "price", value = "价格", required = true, dataType = "float",paramType = "query")
    })


paramType 有五个可选值 ： path, query, body, header, form
例如 我是从路径中去读的值　　http://localhost:8088/bookcurd/1
　　@ApiImplicitParam(name = "id", value = "ID", required = true, dataType = "Long",paramType = "path")

Content-type常见类型：
  1.application/x-www-form-urlencoded
  2.application/json
  3.multipart/form-data
  4.text/xml
  consumes = "application/x-www-form-urlencoded;charset=utf-8"     指定处理请求的提交内容类型（Content-Type），例如application/json, text/html
  produces = "application/json;charset=utf-8"     返回json格式数据



@ApiParam：单个参数描述
@ApiModel：用对象来接收参数
@ApiProperty：用对象接收参数时，描述对象的一个字段
@ApiResponse：HTTP响应其中1个描述
@ApiResponses：HTTP响应整体描述
@ApiIgnore：使用该注解忽略这个API
@ApiError ：发生错误返回的信息
@ApiParamImplicitL：一个请求参数
@ApiParamsImplicit 多个请求参数

package com.youxiu326.controller;

import com.youxiu326.entity.Book;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
