7、配置domain
package com.yami.domain; import java.io.Serializable; public class Product implements Serializable { private static final long serialVersionUID = -7492639752670189553L; private String productId; private String categoryId; private String description; public String getProductId() { return productId; } public void setProductId(String productId) { this.productId = productId.trim(); } public String getCategoryId() { return categoryId; } public void setCategoryId(String categoryId) { this.categoryId = categoryId; } public String getDescription() { return description; } public void setDescription(String description) { this.description = description; } }
配置mapper
package com.yami.mapper; import com.yami.domain.Product; public interface ProductMapper { Product getProduct(String productId); }
配置mapper xml
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.yami.mapper.ProductMapper"> <cache /> <select id="getProduct" parameterType="string" resultType="Product"> SELECT product_id , description, category_id FROM product WHERE product_id = #{productId} </select> </mapper>
