# 1、model定义 #

import lombok.Data;
    
    import javax.validation.constraints.NotNull;
    
    /**
     * @ClassName User
     * @Description:
     * @Author ybwei
     * @Date 2020/8/18
     * @Version V1.0
     **/
    @Data
    public class User {
        @NotNull(message = "id不为空")
        private Long id;
        @NotNull(message = "name不为空")
        private String name;
    }

# 2、接口定义 #

使用@Validated+@Valid

import com.alibaba.fastjson.JSON;
    import com.spring.pro.model.User;
    import lombok.extern.slf4j.Slf4j;
    import org.springframework.validation.annotation.Validated;
    import org.springframework.web.bind.annotation.PostMapping;
    import org.springframework.web.bind.annotation.RequestBody;
    import org.springframework.web.bind.annotation.RestController;
    
    import javax.validation.Valid;
    import java.util.List;
    
    /**
     * @ClassName: ValidateController
     * @Description:
     * @author weiyb
     * @date 2017年12月24日 上午10:26:29
     * 
     */
    @RestController
    @Validated
    @Slf4j
    public class ValidateController {
    
    	/**
    	 * @Description:
    	 * @Param: [user]
    	 * @Return: java.lang.String
    	 * @Author: ybwei
    	 * @Date: 2020/8/18
    	 **/
    	@PostMapping("/test")
    	public String test(@Valid @RequestBody List<User> user){
    		log.info("user:{}", JSON.toJSONString(user));
    		return "OK";
    	}
    }

# 3、请求参数 #

[{
    	"id": 0,
    	"name": "zhangsan0"
    }, {
    	"id": 1,
    	"name": "zhangsan1"
    }, {
    	"id": 2,
    	"name": "zhangsan2"
    }, {
    	"id": 3,
    	"name": "zhangsan3"
    }, {
    	"name": "zhangsan4"
    }]

返回结果

{
        "timestamp": "2020-08-18T06:11:40.976+0000",
        "status": 500,
        "error": "Internal Server Error",
        "message": "test.user[4].id: id不为空",
        "path": "/test"
    }
