thymeleaf : input/select/radio回显

thymeleaf中不用自己去写checked="checked" selected="selected"这种代码，他自己会选。

input

<input type="text" class="form-control1" id="name" name="name" th:value="${user.name}">

select

<label  class="col-sm-2 control-label">类别</label>
<div class="col-sm-8">
    <select  name="cId" id="cId" class="form-control1" >
        <option value="1" th:field="*{book.cId}">目录1</option>
        <option value="2" th:field="*{book.cId}">目录2</option>
        <option value="3" th:field="*{book.cId}">目录3</option>
        <option value="4" th:field="*{book.cId}">目录4</option>
    </select>
</div>

radio（*{回显数据}）

    <label for="isBoy" class="col-sm-2 control-label">是否男生</label>
    <div id="isBoy" class="col-sm-8">
        <div class="radio-inline">
            <label><input name="isBoy" type="radio" value="1"  th:field="*{book.isBoy}"/> 否</label>
        </div>
        <div class="radio-inline">
            <label><input name="isBoy" type="radio" value="0"  th:field="*{book.isBoy}"/> 是</label>
        </div>
    </div>
