@Validated多层校验，不去读文档，在往上东拼西凑，知道这么个东西挺好用。
但是如何去校验对象参数的属性就犯难了。
百度了一下—

是它，是它，就是它 ╮(￣▽ ￣)╭ @Valid

request

public class xxxxxxxxxxxRequest implements Serializable {

    private static final long serialVersionUID = 1L;
    
    @NotBlank(message = "xxxx不能为空")
    private String bidSeq;

    @NotBlank(message = "xxxxxx不能为空")
    private String quoteSeq;
    @Valid
    private QuotePrice quotePrice;
    @Valid
	private List<QuotePrice> quotePrices;
    
public static class QuotePrice implements Serializable {
        
        private static final long serialVersionUID = 1L;

        @NotBlank(message = "报价单项号不能为null")
        private String quoteItemSeq;

        @NotNull(message = "报价类型不能为null")
        private Integer priceType;
        
        @NotBlank(message = "报价金额不能为null")
        private String price;
}
}

controller

    @RequestMapping("/xxxxx")
    public Result<Object> xxxxx(@Validated @RequestBody xxxxxxxxxxxRequest request){
    		return programBidProductService.xxxxx(request);
    }
