首页上点击一级分类跳转到商品列表页面,左侧显示一级分类与二级分类信息。
1、在menu.jsp上添加action,传递一级分类cid。
<li><a href="${pageContext.request.contextPath }/product_findByCid?cid=<s:property value="#c.cid"/>"><s:property value="#c.cname"/></a>|</li>
* cn.itcast.shop.categorysecond
* action
* CategoryAction
* service
* CategoryService
* dao
* CategoryDao
* vo
* CategorySecond
* CategorySecond.hbm.xml
3、配置一级分类和二级分类的关联关系
CategorySecond.hbm.xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping> <class name="cn.xdy.shop.categorySecond.vo.CategorySecond" table="categorysecond"> <id name="csid"> <generator class="native"/> </id> <property name="csname"/> <many-to-one name="category" class="cn.xdy.shop.category.vo.Category" column="cid"/> </class> </hibernate-mapping>
package cn.xdy.shop.categorySecond.vo; import cn.xdy.shop.category.vo.Category; public class CategorySecond { private String csid; private String csname; private Category category; public String getCsid() { return csid; } public void setCsid(String csid) { this.csid = csid; } public String getCsname() { return csname; } public void setCsname(String csname) { this.csname = csname; } public Category getCategory() { return category; } public void setCategory(Category category) { this.category = category; } }Category.hbm.xml中加入CategorySecond的信息
<set name="categorySeconds" lazy="false" order-by="cid"> <key column="cid"/> <one-to-many class="cn.xdy.shop.categorySecond.vo.CategorySecond"/> </set>
private Set<CategorySecond> categorySeconds = new HashSet<CategorySecond>(); public Set<CategorySecond> getCategorySeconds() { return categorySeconds; } public void setCategorySeconds(Set<CategorySecond> categorySeconds) { this.categorySeconds = categorySeconds; }4、编写Action中方法findByCid,因session中有分类信息,所以页面上直接从session中取即可。
/** * 根据分类ID查询所有 * @return */ public String findByCid(){ //因为IndexAction中查询了一级分类存入session中,所以此处不再查询,页面上直接从session中取即可。 return "findByCid"; }
<!-- 商品action --> <action name="product_*" class="productAction" method="{1}"> <result name="findByPid">/WEB-INF/jsp/product.jsp</result> <result name="findByCid">/WEB-INF/jsp/productList.jsp</result> </action>
