如何在JSP中检查字段的内容

我有一张桌子：

<c:forEach var="employee" items="${employees}">
    <tr>
        <td>${employee.id}</td>
        <td>${employee.gender.gender}</td>
        <td>${employee.name}</td>
        <td>${employee.surname}</td>
        <c:if test="${employee.appointment.appointment eq NAVIGATOR}">//Checking value of field
            <td>${employee.appointment.appointment}</td>
        </c:if>
    </tr>
</c:forEach>

${employee.id}
${employee.gender.gender}
${employee.name}
${雇员姓氏}
//字段的检查值
${employee.appointment.appointment}

我要检查字段的值：

${employee.appointment.appointment}

---

如何操作？

如果要检查employee.appointment.appointment的值，则需要将导航器放在类似“NAVIGATOR”的引号中

<c:if test="${employee.appointment.appointment eq 'NAVIGATOR'}">
      <td>${employee.appointment.appointment}</td>
</c:if>

${employee.appointment.appointment}

如果要检查employee.appointment.appointment的值，则需要将导航器放在类似“NAVIGATOR”的引号中

<c:if test="${employee.appointment.appointment eq 'NAVIGATOR'}">
      <td>${employee.appointment.appointment}</td>
</c:if>

${employee.appointment.appointment}
