使用的技术:
Spring+Freemarker
其中Spring包括SpringJdbc、声明式事务、SpringMVC、(单元测试没写,偷个懒)...
View层使用就是FreeMarker+HTML
搭建开发环境:
Spring开发需要的
org.springframework.aop-3.1.0.RELEASE.jar
org.springframework.asm-3.1.0.RELEASE.jar
org.springframework.beans-3.1.0.RELEASE.jar
org.springframework.context-3.1.0.RELEASE.jar

com.springsource.org.apache.commons.logging-1.1.1.jar
com.springsource.org.aspectj.weaver-1.6.8.RELEASE.jar
com.springsource.org.junit-4.7.0.jar
整合FreeMarker需要此Jar
org.springframework.context.support-3.1.0.RELEASE.jar
FreeMarker核心jar文件(就一个)
freemarker.jar
数据库驱动
ojdbc14.jar
开发:
数据库脚本:
--创建商品表 create table guestbook( id varchar2(255) primary key, name varchar2(255), author varchar2(255), price number(6,2), quantity number, description varchar2(255) ); --主键采用UUID,由程序给出
持久层:
package org.chendl.freemarkercrud.dao.impl; import java.io.Serializable; import java.sql.Types; import java.util.List; import org.chendl.freemarkercrud.dao.ProductDao; import org.chendl.freemarkercrud.domain.Product; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.jdbc.core.BeanPropertyRowMapper; import org.springframework.jdbc.core.JdbcTemplate; import org.springframework.stereotype.Repository; @Repository public class ProductDaoImpl implements ProductDao { @Autowired private JdbcTemplate jdbcTemplate; @Override public void save(Product product) { String sql = "INSERT INTO product(id,name,author,price,quantity,description)VALUES(?,?,?,?,?,?)"; Object[] args = { product.getId(), product.getName(), product.getAuthor(), product.getPrice(), product.getQuantity(), product.getDescription() }; int[] argTypes = { Types.VARCHAR, Types.VARCHAR, Types.VARCHAR, Types.DECIMAL, Types.INTEGER, Types.VARCHAR }; jdbcTemplate.update(sql, args, argTypes); } @Override public void update(Product product) { String sql = "UPDATE product SET name=?,author=?,price=?,quantity=?,description=? WHERE id=?"; Object[] args = { product.getName(), product.getAuthor(), product.getPrice(), product.getQuantity(), product.getDescription(), product.getId() }; int[] argTypes = { Types.VARCHAR, Types.VARCHAR, Types.DECIMAL, Types.INTEGER, Types.VARCHAR, Types.VARCHAR }; jdbcTemplate.update(sql, args, argTypes); } @Override public void delete(Serializable id) { String sql = "DELETE FROM product WHERE id=?"; Object[] args = { id }; int[] argTypes = { Types.VARCHAR }; jdbcTemplate.update(sql, args, argTypes); } @Override public Product findById(Serializable id) { String sql = "SELECT * FROM product WHERE id=?"; List<Product> list = jdbcTemplate.query(sql, BeanPropertyRowMapper.newInstance(Product.class), id); return list.get(0); } @Override public List<Product> findAll() { String sql = "SELECT * FROM product"; List<Product> list = jdbcTemplate.query(sql, BeanPropertyRowMapper.newInstance(Product.class)); return list; } }
业务层很简单就是调用Dao而已,具体的看附件
Web层:
package org.chendl.freemarkercrud.web.action; import java.util.List; import org.chendl.freemarkercrud.domain.Product; import org.chendl.freemarkercrud.service.ProductService; import org.chendl.freemarkercrud.util.ToolUtil; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; @Controller public class ProductController { @Autowired private ProductService productService; /** 列表 */ @RequestMapping("/list.action") public ModelAndView list() { List<Product> list = productService.getAll(); return new ModelAndView("list", "list", list); } /** 添加页面 */ @RequestMapping("/saveUI.action") public String saveUI() { return "save"; } /** 添加 */ @RequestMapping("/save.action") public String save(Product product) { product.setId(ToolUtil.getUUID()); //设置主键UUID productService.save(product); return "redirect:list.action"; } /** 编辑页面 */ @RequestMapping("/editUI.action") public ModelAndView editUI(String id) { Product product = productService.getById(id); return new ModelAndView("edit", "product", product); } /** 编辑 */ @RequestMapping("/edit.action") public String edit(Product product) { productService.update(product); return "redirect:list.action"; } /** 删除 */ @RequestMapping("/delete.action") public String delete(String id) { productService.delete(id); return "redirect:list.action"; } }

以上的是关键代码。
今天也是自己第一天学FreeMarker。上面写的就当做自己的一份笔记。
感性觉得ftl比jsp快,第一次运行几乎不需要等待,而且配置很灵活。
但是还有一个问题没有解决:乱码问题。google后,也没找到太好的方法,可能没找对。
留个疑问吧... 希望有“达人”留言...不胜感激...
