mysql - foreach内部sql :query jSTL

Question

我有 2 个 jsp 文件，第一个文件中有一个表单:

        <form action="searchresult" method="POST"> Words seperated by commas <br><br><br>
            Enter words you look for: <input type="text" name="searchText" value="" />
            <button type="submit" name="titleSearch" value="costam">Search in title</button>
            <button type="submit" name="contentSearch">Search in content</button>
        </form>  

在第二个jsp中，我从上面的表单中分割了文本

        <c:set var="searchText" value="${param.searchText}"/>
        <c:set var="splitted" value="${fn:split(searchText, ',')}" />

然后我想检查数据库中的任何记录是否包含“分割”数组中的任何单词

        <c:if test="${not empty param.titleSearch}">
            <sql:query var="result1" dataSource="jdbc/myProba">
                SELECT title, shortcon FROM bazaprojekt.ad WHERE
                    <c:forEach items="${splitted}" var="word">
                        title LIKE ? <sql:param value='${word}'/> OR
                    </c:forEach>
            </sql:query>
        </c:if>
            <c:forEach var="row" items="${result1.rows}">  
                <div class="adtitle">
                    <a href="singlead?idad=<c:out value="${row.idad}"/>"><c:out value="${row.title}"/></a>                        
                    <p>
                    <c:out value="${row.shortcon}"/>
                    </p>
                </div>
            </c:forEach> 

我试图在循环中执行此操作，但这当然不起作用。正确的做法是什么？

感谢您的回答，Sas，我想它会起作用，无论如何我自己解决了它，这是代码:

        <c:if test="${not empty param.titleSearch}">
            <sql:query var="result1" dataSource="jdbc/myProba">
                SELECT idad, title, shortcon FROM bazaprojekt.ad WHERE
                <c:if test="${fn:length(splitted) == 1}">
                    <c:forEach items="${splitted}" var="word">
                        title LIKE '%<c:out value='${word}'/>%'
                    </c:forEach>
                </c:if>
                <c:if test="${fn:length(splitted)  > 1}">
                    <c:forEach items="${splitted}" var="word" begin="0" end="${fn:length(splitted) -2}">
                        title LIKE '%<c:out value='${word}'/>%' OR
                    </c:forEach>
                    <c:forEach items="${splitted}" var="word" begin="${fn:length(splitted) -1}" end="${fn:length(splitted) -1}">
                        title LIKE '%<c:out value='${word}'/>%'
                    </c:forEach>                            
                </c:if>                            
            </sql:query>
        </c:if>
