1 在jsp页面加上 orderable 和 orderableProperty
<liferay-ui:search-container-column-text name="updateDate" value="${updateDate}" orderable="<%= true %>" orderableProperty="updateDate" />
2. 自定义排序的类
package com.labimo.lesson.portlet.util; import com.labimo.lesson.model.Lesson; import com.liferay.portal.kernel.util.OrderByComparator; import com.liferay.portal.kernel.util.OrderByComparatorFactory; public class LessonNameComparator extends OrderByComparator { private static final long serialVersionUID = -4030654580941693641L; public static String ORDER_COl = "name"; public static String ORDER_BY_ASC = "name ASC"; public static String ORDER_BY_DESC = "name DESC"; public LessonNameComparator() { this(false); } public LessonNameComparator(boolean asc) { _asc = asc; } public int compare(Object obj1, Object obj2) { Lesson instance1 = (Lesson) obj1; Lesson instance2 = (Lesson) obj2; int value = instance1.getName().toLowerCase().compareTo(instance2.getName().toLowerCase()); if(_asc) { return value; } else { return -value; } } public String getOrderBy() { if (_asc) { return ORDER_BY_ASC; } else { return ORDER_BY_DESC; } } private boolean _asc; }
在MVCPortlet 的自实现类里面加上下面代码
// sort String orderByCol = ParamUtil.getString(renderRequest, "orderByCol"); String orderByType = ParamUtil.getString(renderRequest, "orderByType"); String curValue = ParamUtil.getString(renderRequest, "curr"); if(Validator.isNull(orderByCol)){ orderByCol = LessonNameComparator.ORDER_COl; } if(Validator.isNull(orderByType)){ orderByType = "asc"; } OrderByComparator orderByComparator = null ; if(LessonNameComparator.ORDER_COl.equals(orderByCol)){ if(orderByType!=null && orderByType.equalsIgnoreCase("desc")){ orderByComparator = new LessonNameComparator(false); }else{ orderByComparator = new LessonNameComparator(true); } } // 设置传进来的值 searchContainer.setOrderByCol(orderByCol); searchContainer.setOrderByType(orderByType);
