jquery转发器

$(document).ready(function () {
        'use strict';
        window.id = 0;
        $('.repeater').repeater(
            {
                show: function () {
                    $(this).slideDown();
                },
                hide: function (deleteElement) {
                    $(this).slideUp(deleteElement);
                },
                defaultValues: {
                    'fieldName': 'authorsLastName',
                    'operator': 'equal',
                    'conjunctionOperator': 'and'
                },
                initEmpty: true
            }
        );
    });

Spring Controller

@RequestMapping(value = "/post/report2", method = RequestMethod.POST)
    public ModelAndView viewPostReport2(@RequestParam(value="filterInputs[][]") String[][] filterputsm, HttpServletRequest request) throws Exception {
        try {
            ModelAndView view = new ModelAndView("report/post-report");
            return view;
        } catch (Exception e) {
            LOGGER.error(e.getMessage());
            e.printStackTrace();
            throw e;
        }
    }

日志

Resolved [org.springframework.web.bind.MissingServletRequestParameterException: Required String[][] parameter 'filterInputs[][]' is not present]

错误页面

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Bad Request, status=400).
Required String[][] parameter 'filterInputs[][]' is not present

Formdata

filterInputs[0][id]: 
filterInputs[0][fieldName]: authorsLastName
filterInputs[0][operator]: equal
filterInputs[0][searchValue]: 
filterInputs[0][conjunctionOperator]: and
filterInputs[1][id]: 
filterInputs[1][fieldName]: authorsLastName
filterInputs[1][operator]: equal
filterInputs[1][searchValue]: 
filterInputs[1][conjunctionOperator]: and
filterInputs[2][id]: 
filterInputs[2][fieldName]: authorsLastName
filterInputs[2][operator]: equal
filterInputs[2][searchValue]: 
filterInputs[2][conjunctionOperator]: and

我面临的问题是将上述表单数据提交给spring控制器。我曾尝试使用@ModelAttribute和包装器类如下

@Data
@NoArgsConstructor
public class FilterWrapper {

    List<FilterInput> filterInputs = Collections.emptyList();
}

@Data
@NoArgsConstructor
public class FilterInput {
    @NotNull
    private String fieldName;

    @NotNull
    private String operator;

    @NotNull
    private String searchValue;

    private String conjunctionOperator;

    private String id;
}

错误：Bean类[com.misyn.datatable.mapping.FilterWrapper]的无效属性'filterInputs [0] [conjunctionOperator]'：非法尝试获取属性'filterInputs'引发异常；嵌套的异常是java.lang.UnsupportedOperationExceptio
