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>
2、创建二级分类的包及类
* 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>
CategorySecond.java
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>
Category.java中加入二级分类信息
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";
}
5、Struts.xml中配置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>
6、编写productList.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
