《Spring开发流程》doc版.doc

1 建立工程首先在eclipses上建立一个web工程，点击File-new-Others，选择Web Project，如下图所示：点击next，在Project Name中填入工程名称，在J2EE Specificatio Level选项中选择J2EE1.4，点击Finish就建立了一个Structs工程。2 引入Spring需要的jar包将spring.jar，commons-logging-1.0.4.jar，standard.jar，log4j-1.2.9.jar，jstl.jar包拷贝到工程所在目录WebRoot/WEB-INF/lib下。3. 发JSP页面主要有两个JSP页面，分别为hello.jsp和priceincrease.jsp。Include.jsp:引入了jstl的两个标签Index.jsp 启动后便跳转到hello.htm页面 Example - Spring Application This is my test. Hello.jsp：headingGreeting Products$a href=Increase PricesPriceincrease.jsp：Increase (%):input type=text name=percentage value=Please fix all errors!a href=Home4. 开发业务逻辑程序1)com.zznode.dp.springapp.bus包Poduct.java ： Product的JavaBeanpackage com.zznode.dp.springapp.bus;import java.io.Serializable;public class Product implements Serializable private String description; private double price; private int id;public void setId(int i) id = i; public int getId() return id; public void setDescription(String s) description = s; public String getDescription() return description; public void setPrice(double d) price = d; public double getPrice() return price; ProductManager.java 类似EJB，提供了两个对Product的操作：getProducts()和increasePrice()，分别来获得所有产品列表和增加产品价格。package com.zznode.dp.springapp.bus;import java.io.Serializable;import java.util.List;import java.util.ListIterator;import com.zznode.dp.springapp.db.ProductManagerDao;public class ProductManager implements Serializable private List products; private ProductManagerDao pmd;public void setProductManagerDao(ProductManagerDao pmd) this.pmd = pmd; public void setProducts(List p) products = p; public List getProducts() products = pmd.getProductList();return products; public void increasePrice(int pct) ListIterator li = products.listIterator(); while (li.hasNext() Product p = (Product) li.next(); pmd.increasePrice(p, pct); PriceIncrease.java package com.zznode.dp.springapp.bus;import mons.logging.Log;import mons.logging.LogFactory;public class PriceIncrease /* Logger for this class and subclasses */ protected final Log logger = LogFactory.getLog(getClass(); private int percentage; public void setPercentage(int i) percentage = i; (Percentage set to + i); public int getPercentage() return percentage; PriceIncreaseValidator.java 对增加的价格进行验证的类，验证输入的增加价格是否超过50%package com.zznode.dp.springapp.bus;import java.io.Serializable;import org.springframework.validation.Validator;import org.springframework.validation.Errors;import mons.logging.Log;import mons.logging.LogFactory;public class PriceIncreaseValidator implements Validator private int DEFAULT_MIN_PERCENTAGE = 0; private int DEFAULT_MAX_PERCENTAGE = 50; private int minPercentage = DEFAULT_MIN_PERCENTAGE; private int maxPercentage = DEFAULT_MAX_PERCENTAGE; /* Logger for this class and subclasses */ protected final Log logger = LogFactory.getLog(getClass(); public boolean supports(Class clazz) return clazz.equals(PriceIncrease.class); public void validate(Object obj, Errors errors) PriceIncrease pi = (PriceIncrease) obj; if (pi = null) errors.rejectValue(percentage, error.not-specified, null, Value required.); else (Validating with + pi + : + pi.getPercentage(); if (pi.getPercentage() maxPercentage) errors.rejectValue(percentage, error.too-high,new Object new Integer(maxPercentage), Value too high.); if (pi.getPercentage() = minPercentage) errors.rejectValue(percentage, error.too-low,new Object new Integer(minPercentage), Value too low.); public void setMinPercentage(int i) minPercentage = i; public int getMinPercentage() return minPercentage; public void setMaxPercentage(int i) maxPercentage = i; public int getMaxPercentage() return maxPercentage; 2)com.zznod.dp.springapp.webPriceIncreaseFormController.java PriceIncrease.jsp的窗口控制类，当用户输入增加价格后点击提交按钮后，将调用本类的onSubmit()函数，然后调用ProductManager类提供的接口对价格进行计算和入库。package com.zznode.dp.springapp.web;import org.springframework.web.servlet.mvc.SimpleFormController;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.view.RedirectView;import javax.servlet.ServletException;import javax.servlet.http.HttpServletRequest;import mons.logging.Log;import mons.logging.LogFactory;import com.zznode.dp.springapp.bus.ProductManager;import com.zznode.dp.springapp.bus.PriceIncrease;public class PriceIncreaseFormController extends SimpleFormController /* Logger for this class and subclasses */ protected final Log logger = LogFactory.getLog(getClass(); private ProductManager prodMan; public ModelAndView onSubmit(Object command) throws ServletException int increase = (PriceIncrease) command).getPercentage(); prodMan.increasePrice(increase); (Increasing prices by + increase + %.); (returning from PriceIncreaseForm view to + getSuccessView(); return new ModelAndView(new RedirectView(getSuccessView(); protected Object formBackingObject(HttpServletRequest request) throws ServletException PriceIncrease priceIncrease = new PriceIncrease(); priceIncrease.setPercentage(20); return priceIncrease; public void setProductManager(ProductManager pm) prodMan = pm; public ProductManager getProductManager() return prodMan; SpringappController.java 主页面的控制类，调用handleRequest()函数对请求进行处理，在本例中，在页面显示当前时间，并显示所有产品的描述和价格信息package com.zznode.dp.springapp.web;import org.springframework.web.servlet.mvc.Controller;import org.springframework.web.servlet.ModelAndView;import javax.servlet.ServletException;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import java.io.IOException;import mons.logging.Log;import mons.logging.LogFactory;import java.util.Map;import java.util.HashMap;import com.zznode.dp.springapp.bus.Product;import com.zznode.dp.springapp.bus.ProductManager;public class SpringappController implements Controller /* Logger for this class and subclasses */ protected final Log logger = LogFactory.getLog(getClass(); private ProductManager prodMan;public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException (SpringappController - returning hello view);String now = (new java.util.Date().toString(); (returning hello view with + now); Map myModel = new HashMap(); myModel.put(now, now); myModel.put(products, getProductManager().getProducts(); return new ModelAndView(hello, model, myModel);public void setProductMana
