我是Spring MVC的新手，试图编写基于Web的应用程序。
org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.IllegalArgumentException: setAttribute:
名称不可序列化的属性
InventoryMgmtSpring.web.PriceIncreaseFormController.FORM.priceIncrease
根本原因
java.lang.IllegalArgumentException: setAttribute: Non-serializable attribute with name InventoryMgmtSpring.web.PriceIncreaseFormController.FORM.priceIncrease
app-servelet.xml中的代码片段
<bean name="/priceincrease.htm" class="InventoryMgmtSpring.web.PriceIncreaseFormController">
<property name="sessionForm" value="true"/>
<property name="commandName" value="priceIncrease"/>
<property name="commandClass" value="InventoryMgmtSpring.service.PriceIncrease"/>
<property name="validator">
<bean class="InventoryMgmtSpring.service.PriceIncreaseValidator"/>
</property>
<property name="formView" value="priceincrease.htm"/>
<property name="successView" value="hello.htm"/>
<property name="productManager" ref="productManager"/>
</bean>
来自PriceIncreaseFormController的代码-----
public class PriceIncreaseFormController extends SimpleFormController {
/** Logger for this class and subclasses */
protected final Log logger = LogFactory.getLog(getClass());
private ProductManager productManager;
public ModelAndView onSubmit(Object command) throws ServletException {
int increase = ((PriceIncrease) command).getPercentage();
logger.info("Increasing prices by " + increase + "%.");
productManager.increasePrice(increase);
logger.info("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 productManager) {
this.productManager = productManager;
}
public ProductManager getProductManager() {
return productManager;
}
}
PriceIncrease中的代码段
= ------------------------------
public class PriceIncrease {
/** Logger for this class and subclasses */
protected final Log logger = LogFactory.getLog(getClass());
private int percentage ;
public void setPercentage(int i)
{
this.percentage=i;
logger.info("Percentage set to" + i);
}
public int getPercentage()
{
return percentage;
}
}
最佳答案
首先，我将避免在PriceIncrease中使用Logger，而将PriceIncrease视为POJO。很难确定问题的根本原因到底是什么，但是我认为问题可能出在您尝试序列化记录器时。尝试删除记录器或在log变量之前添加关键字transient。
希望对您有所帮助。
