搜索功能的实现

Controller层

/**
     * Lcsx列表界面
     *
     * @return
     */
    @RequestMapping(value = "/lcsxListUI")
    @HtmlTitle(title = "临床舌象")
    public String lcsxListUI(Model model, @ModelAttribute("search") LcsxSearch search, @PageableDefault(size = 10)Pageable pageable){
        Page<Lcsx> lcsxes = lcsxService.findLcsxPage(search,pageable);
        model.addAttribute("page",lcsxes);
        return "sysAdmin/lcsx/lcsxListUI";
    }

Service

/**
     * Lcsx列表界面
     *
     * @param search
     * @param pageable
     * @return
     */
    public Page<Yggl> findYgglPage(YgglSearch search, Pageable pageable) {
        Page<Yggl> ygglPage = ygglRepository.findAll((root, query, cb) -> {
            List<Predicate> predicateList = new ArrayList<>();
            if (StringUtils.isNotBlank(search.getTsch())) {
                predicateList.add(cb.like(root.get("tsch"), "%" + search.getTsch() + "%"));
            }
            if (search.getKsrq()!= null) {
                predicateList.add(cb.greaterThanOrEqualTo(root.get("ksrq"), DateUtils
                        .parseDate(DateUtils.formatDate(search.getKsrq(), "yyyy-MM-dd") + " 00:00:00")));
            }
            if (search.getJsrq() != null) {
                predicateList.add(cb.lessThanOrEqualTo(root.get("jsrq"), DateUtils
                        .parseDate(DateUtils.formatDate(search.getJsrq(), "yyyy-MM-dd") + " 23:59:59")));
            }
            query.where(predicateList.toArray(new Predicate[]{}));
            return null;
        }, pageable);
        return ygglPage;
    }

针对封装（vo层）

package org.lf.admin.api.baseapi.vo;

import lombok.Data;

import java.sql.Date;

@Data
public class YgglSearch {

    private String tsch;

    private Date ksrq;

    private Date jsrq;

}

主界面（html）

<div class="list-search">
            <form th:action="@{/yggl/ygglListUI}"
                  class="form-inline input-line" th:method="post" id="search-form" name="searchForm">
