1.问题：前端到底能不能将BigDecimal传个我啊？

答：虽然说前端没有这样的数据类型，但是后台能接受到成BigDecimal

2.问题：themleaf对于如果是1则显示A 如果是2显示B 如果是3显示C 如果是4显示D

虽然有th:text="${a==a?'a':'不是a'}”我这个岂不是写的又臭又长

答：是的

内容如下，真实可测

<td th:text="${worksheetOne.worksheetPrior==1?'A':( worksheetOne.worksheetPrior==2?'B':(worksheetOne.worksheetPrior==3?'C':(worksheetOne.worksheetPrior==4?'D':worksheetOne.worksheetPrior)))  }">A</td>

3.themleaf字符串截取，前10位

th:text="${#strings.abbreviate(worksheetOne.content,10)}"

str截取0-10位，后面的全部用…这个点代替，注意，最小是3位

4.对象传参方法如下

function findEmpByUserId() {
    var userId = parseInt($(".p_user").text());
    console.log("hehe"+userId);
    util.ajax('/setting/empList/findEmpByName?userId='+userId, {}, function (result) {
        if (result.success) {
            console.log(result)
            console.log(result.spUserDto.fullName);
            $(".p_user").text(result.spUserDto.fullName);
        }
    });
}

而不是

function findEmpByUserId() {
    var userId = parseInt($(".p_user").text());
    console.log("hehe"+userId);
    util.ajax('/setting/empList/findEmpByName', {userId: userId}, function (result) {
        if (result.success) {
            $('#p_user').append("<p>" + result + "</p>")
        }
    });
}

5.themleaf 后台需要传入page对象

 <ul class="pagination" th:if="${!#lists.isEmpty(contractResourceDtoList)}">
                <li><a href="#" th:href="@{'/resource/resourceInfo?resourceId='+${resourceDto.resourceId}+'&pageNo1='+${page1.previous}}">«</a></li>
                <li th:each="i : ${#numbers.sequence(page1.pageFrom, page1.pageTo, 1)}" th:class="${i} == ${page1.page} ? 'active' : ''">
                    <a href="#" th:href="@{'/resource/resourceInfo?resourceId='+${resourceDto.resourceId}+'&pageNo1='+${i}}" th:text="${i}">1</a>
                </li>
                <li><a href="#" th:href="@{'/resource/resourceInfo?resourceId='+${resourceDto.resourceId}+'&pageNo1='+${page1.next}}">»</a></li>
            </ul>

5.themleaf 或者表达式写法

  <div th:if="${list.pdType} == 5 or ${list.pdType}==6">... do something ...</div>
