背景：在開發(fā)中特別是做保存邏輯的時候，后端需要接收很多業(yè)務(wù)參數(shù)。
html頁面（上傳的參數(shù)js對象和Java對象對應(yīng)，js數(shù)組和Java集合對應(yīng)，字段名字也要對應(yīng)）：

Controller處理器：
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;
}
}
實體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 {
