    private int page;

    private int pageSize;

    private String sort;

    private String order;

    private Map<String,Objects> searchParams;

    public int getPage() {
        return page;
    }

    public void setPage(int page) {
        this.page = page;
    }

    public int getPageSize() {
        return pageSize;
    }

    public void setPageSize(int pageSize) {
        this.pageSize = pageSize;
    }

    public void setSort(String sort) {
        this.sort = sort;

    参数格式不对···拼json····{“searchParams”:[{key:value},{key,value}]}searchParams你定义的是map类型。其实吧,传参还是按照之前的方法就行,这和springboot没有关系。可以查看我的spring文章系列
    麻烦你用swagger整合一下,然后自己看看swagger发出的,和你自己发出的,有什么不同。好的谢谢
