To beautify the interface using Bootstrap, you can add Bootstrap classes to the HTML elements. Here's an example of how you can modify the given code to use Bootstrap classes:

<div id="main" class="wrap clearfix">
    <div id="content" class="col-md-8">
        <div class="info-list-wrap clearfix" id="info-list-lost">
            <div class="info-title-wrap">
                <h2><a href="goods!lost">最新求助信息</a></h2>
                <span class="info-list-more pull-right">
                    <a href="goods!lost">查看所有>;&gt;</a>
                </span>
            </div>
            <ul class="info-list">
                <li class="clearfix">
                    <span class="event-goods-type">物品类别</span>
                    <span class="event-goods">物品名称</span>
                    <span class="event-time">丢失时间</span>
                    <span class="event-address">丢失地点</span>
                    <span class="event-title">标题</span>
                </li>
                <c:forEach items="${lostlist}" var="bean">
                    <li class="clearfix">
                        <span class="event-goods-type">${bean.category.cname }</span>
                        <span class="event-goods">${bean.name}</span>
                        <span class="event-time"><fmt:formatDate value="${bean.happentime}" pattern="yyyy-MM-dd"/></span>
                        <span class="event-address">${bean.address}</span>
                        <span class="event-title">
                            <a href="repair!view?id=${bean.id}">
                                ${fn:substring(bean.title,0,18)}<c:if test="${fn:length(bean.title)>18 }">...</c:if>
                            </a>
                        </span>
                    </li>
                </c:forEach>
            </ul>
        </div>
        <div class="info-list-wrap clearfix" id="info-list-found">
            <div class="info-title-wrap">
                <h2><a href="repair!find">最新维修工具耗材</a></h2>
                <span class="info-list-more pull-right">

            <ul class="info-list">

                    <span class="event-time">捡到时间</span>
                    <span class="event-address">捡到地点</span>
                    <span class="event-title">标题</span>
                </li>
                <c:forEach items="${findlist}" var="bean">
                    <li class="clearfix">
                        <span class="event-goods-type">${bean.category.cname }</span>

                        <span class="event-title">
                            <a href="repair!view?id=${bean.id}">
                                ${fn:substring(bean.title,0,18)}<c:if test="${fn:length(bean.title)>18 }">...</c:if>
                            </a>
                        </span>
                    </li>
                </c:forEach>
            </ul>
        </div>
    </div>
    <div id="sidebar" class="col-md-4">
        <div id="publish">
            <img alt="" src="sta/pic/logo.jpg" class="img-responsive">
        </div>
        <div id="office" class="side-box">
            <div class="clearfix" id="office-title-wrap">
                <h3 id="office-title">教学楼失物招领地点</h3>
            </div>
            <ul id="office-content">
                <li class="office-item">
                    失物招领处：113室&nbsp;&nbsp;&nbsp;&nbsp;电话：812345678
                </li>
            </ul>
        </div>
        <div></div>
    </div>
</div>

In the above code, I have added Bootstrap classes like col-md-8 and col-md-4 to create a responsive layout with two columns for the content and sidebar. I have also used classes like pull-right and img-responsive to align elements and make the image responsive.

Remember to include the Bootstrap CSS and JS files in your HTML file for the styles and functionality to work properly
