注：

[[${coder.user_name}]] 和 <span th:text="${coder.user_name}">span> 两种写法作用相同。

pagehelper插件的封装实体类pageInfo有两个属性prePage和nextPage，表示上一页的页码数和下一页的页码数，可以方便用来写上一页和下一页的功能。

thymeleaf给方法传入前台参数的写法:th:οnclick="pass([[${coder.coder_id}]])"

代码举例：

<tr th:each="coder,coderList:${pageInfo.list}">
    <td><input name="ids" type="checkbox">td>
    <td>
        [[${coder.user_name}]]
    td>
    <td>[[${coder.user_name}]]td>
    <td>[[${coder.user_name}]]td>
    <td>[[${coder.user_name}]]td>
    <td>[[${coder.user_name}]]td>
    <td>[[${coder.user_name}]]td>
    <td>[[${coder.user_name}]]td>
    <td><span th:text="${coder.coder_classification}">span>td>

    <td class="text-center">
        <button type="button" class="btn bg-olive btn-xs" th:onclick="pass([[${coder.coder_id}]])">通过button>
        <button type="button" class="btn bg-yellow btn-xs" th:onclick="fail([[${coder.coder_id}]])">不通过button>
    td>
tr>

<div class="pull-left">
    <div class="form-group form-inline">
        总共[[${pageInfo.pages}]]页，共[[${pageInfo.total}]]条数据。 每页
        <select class="form-control" id="changePageSize" onchange="changePageSize()">
            <option value="2" th:selected="${pageInfo.size == 2}">2option>
            <option value="4" th:selected="${pageInfo.size == 4}">4option>
            <option value="6" th:selected="${pageInfo.size == 6}">6option>
            <option value="8" th:selected="${pageInfo.size == 8}">8option>
            <option value="10" th:selected="${pageInfo.size == 10}">10option>
        select> 条
