优雅的接收参数
接收参数
接收请求参数和自定类型转换器
服务端接收访问数据
Springboot 接收参数的几种常用方式
微信小程序使用navigateTo进行数据传递
react-router-dom部分笔记
React中向路由组件传递参数
call 和 apply
Restful风格

背景：在开发中特别是做保存逻辑的时候，后端需要接收很多业务参数。
html页面（上传的参数js对象和Java对象对应，js数组和Java集合对应，字段名字也要对应）：

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<script src='jquery-2.1.4.min.js'></script>
</head>
<body>
    <button onclick='send()'>try</button>
    
    <script>
        function send(){
            var obj = new Object();
            
            // 基本信息
            var baseInfo = new Object();
            baseInfo.name = 'tianye';
            baseInfo.age = 18;
            baseInfo.sex = '男';
            obj.baseInfo = baseInfo;
            
            // 折扣优惠
            var discount = new Array();
            var discountChild1 = new Object();
            discountChild1.discountIds = '1,2,3';
            discountChild1.productIds = '12,23,45,23';
            var discountChild2 = new Object();
            discountChild2.discountIds = '12,222,322';
            discountChild2.productIds = '122,233,455,2366';
            discount.push(discountChild1);
            discount.push(discountChild2);
            obj.discount = discount;
            
            // 楼栋别名
            var product = new Array();
            var productChild1 = new Object();
            var productChild2 = new Object();
            productChild1.id = 222;
            productChild1.name = 'sasfds';
            productChild1.sort = 2;
            productChild2.id = 333;
            productChild2.name = 'sfdsfdsfsadf';
            productChild2.sort = 1;
            product.push(productChild1,productChild2);
            obj.product = product;
            
            console.log(obj);
            console.log(JSON.stringify(obj));
            
            $.ajax({
                url: 'http://localhost:8080/ajax/test1',
                type: 'post',
                contentType: 'application/json;charset=utf-8',
                data: JSON.stringify(obj),
                success: function(data){
                    console.log(data);
                    console.log(JSON.stringify(data));
                }
            });
        }
    </script>
 
</body>
</html>

Controller处理器：

package com.example.demo.web;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import com.example.demo.domain.AjaxDTO;

@Controller
@RequestMapping("/ajax")
public class AjaxController {
    
    @RequestMapping("/test1")
    @ResponseBody
    public AjaxDTO test1(@RequestBody AjaxDTO AjaxDTO) {
        System.out.println(AjaxDTO.getBaseInfo());
        System.out.println(AjaxDTO.getDiscount());
        System.out.println(AjaxDTO.getProduct());
        return AjaxDTO;
    }

}

实体Bean

package com.example.demo.domain;
import java.util.List;
public class AjaxDTO {
    
    private BaseInfo baseInfo;
    
    private List<Discount> discount;
    
    private List<Product> product;

    // 忽略get，set方法
}


package com.example.demo.domain;
public class BaseInfo {
    
    private String name;
    
    private Integer age;
    
    private String sex;

    // 忽略get，set方法
}


package com.example.demo.domain;
public class Discount {
    
    private String discountIds;
    
    private String productIds;

    // 忽略get，set方法
}


package com.example.demo.domain;
public class Product {
    
    private Integer id;
    
    private String name;
    
    private Integer sort;

    // 忽略get，set方法
}
