postman测试传参格式

• 创建User实体

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

@Data
@NoArgsConstructor
@AllArgsConstructor
public class User {

    private Integer id;

    private String name;
}

1. 接口参数是集合

	@PostMapping("/test1")
    public String test1(@RequestBody List<User> userList) {

        return "SUCCESS";

    }

postman传参形式：

[
    {
        "id": 1,
        "name": "ff"
    },
    {
        "id": 2,
        "name": "dfu"
    }
]

测试结果：

2. bean实体传参

①创建DTO，封装List集合

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import java.util.List;

@Data
@AllArgsConstructor
@NoArgsConstructor
public class UserDTO {

    private List<User> userList;

}

②参数传DTO

 @PostMapping("/test2")
    public String test2(@RequestBody UserDTO userDTO) {

        return "userDTO SUCCESS";

    }

③JSON传参形式

{
    "userList": [
        {
            "id": 1,
            "name": "ff"
        },
        {
            "id": 2,
            "name": "dfu"
        }
    ]
}

④postman测试
