博客探讨了在Spring MVC中，一个Controller方法是否能够同时接收两个@RequestBody注解的参数，通过实例展示了如何实现这一操作，并展示了控制台打印的结果以及相关的实体类Product和ProductOrder。

看图：

controller层

    @RequestMapping("/testJson")
    public void testJson(@RequestBody Product product, String gender, @RequestBody ProductOrder order){
        System.out.println(order);
        System.out.println(gender);
        System.out.println(product);

    }

控制台打印

实体类Product

package com.techman.tmy.entity;

import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.Data;

import java.util.Date;
@Data
public class Product {
    private  int id;
    private String category;
    private String name;
    private  String productNo;
    private   String description;
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8" )
    private Date createTime;

}

实体类ProductOrder

package com.techman.tmy.entity;

import com.fasterxml.jackson.annotation.JsonFormat;
import lombok.Data;

import java.util.Date;
@Data
public class ProductOrder {
    private int id;
    private int productId;
    private int editionId;
    private String orderNo;
    private String status;
    private String description;
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8" )
    private Date createTime;
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss", timezone = "GMT+8" )
    private  Date modifyTime;}`
