jpetstore 中的struts代码

JPetStore是一个使用Java和Struts框架开发的示例应用程序，用于演示如何使用Java技术构建Web应用程序。

下面是JPetStore中的Struts代码示例：

1. struts-config.xml文件

这是Struts框架的配置文件，它定义了应用程序中所有操作的配置。

<struts-config>
  <form-beans>
    <form-bean name="AccountForm" type="org.mybatis.jpetstore.web.actions.AccountActionForm"/>
    <form-bean name="CatalogForm" type="org.mybatis.jpetstore.web.actions.CatalogActionForm"/>
    <form-bean name="OrderForm" type="org.mybatis.jpetstore.web.actions.OrderActionForm"/>
  </form-beans>

  <global-exceptions>
    <exception key="error.database" type="org.mybatis.jpetstore.web.util.DBException"/>
    <exception key="error.exception" type="org.mybatis.jpetstore.web.util.GeneralException"/>
    <exception key="error.login.required" type="org.mybatis.jpetstore.web.util.AuthenticationException"/>
  </global-exceptions>

  <global-forwards>
    <forward name="welcome" path="/actions/Catalog.action"/>
    <forward name="failure" path="/error.jsp"/>
  </global-forwards>

  <action-mappings>
    <action path="/actions/Catalog.action" name="CatalogForm" scope="request" type="org.mybatis.jpetstore.web.actions.CatalogAction">
      <forward name="success" path="/WEB-INF/jsp/catalog/Main.jsp"/>
      <forward name="failure" path="/error.jsp"/>
    </action>

    <action path="/actions/CatalogSearch.action" name="CatalogForm" scope="request" type="org.mybatis.jpetstore.web.actions.CatalogSearchAction">
      <forward name="success" path="/WEB-INF/jsp/catalog/SearchProducts.jsp"/>
      <forward name="failure" path="/error.jsp"/>
    </action>

    <action path="/actions/ViewProduct.action" name="CatalogForm" scope="request" type="org.mybatis.jpetstore.web.actions.ViewProductAction">
      <forward name="success" path="/WEB-INF/jsp/catalog/Product.jsp"/>
      <forward name="failure" path="/error.jsp"/>
    </action>

    <action path="/actions/AddItemToCart.action" name="CatalogForm" scope="session" type="org.mybatis.jpetstore.web.actions.AddItemToCartAction">
      <forward name="success" path="/WEB-INF/jsp/catalog/Cart.jsp"/>
      <forward name="failure" path="/error.jsp"/>
    </action>

    <action path="/actions/RemoveItemFromCart.action" name="CatalogForm" scope="session" type="org.mybatis.jpetstore.web.actions.RemoveItemFromCartAction">
      <forward name="success" path="/WEB-INF/jsp/catalog/Cart.jsp"/>
      <forward name="failure" path="/error.jsp"/>
    </action>

    <action path="/actions/ViewCart.action" name="CatalogForm" scope="request" type="org.mybatis.jpetstore.web.actions.ViewCartAction">
      <forward name="success" path="/WEB-INF/jsp/catalog/Cart.jsp"/>
    </action>

    <action path="/actions/Checkout.action" name="OrderForm" scope="request" type="org.mybatis.jpetstore.web.actions.CheckoutAction">
      <forward name="success" path="/WEB-INF/jsp/order/Checkout.jsp"/>
    </action>

    <action path="/actions/NewOrder.action" name="OrderForm" scope="request" type="org.mybatis.jpetstore.web.actions.NewOrderAction">
      <forward name="success" path="/WEB-INF/jsp/order/ViewOrder.jsp"/>
      <forward name="failure" path="/error.jsp"/>
    </action>

    <action path="/actions/ListOrders.action" name="AccountForm" scope="request" type="org.mybatis.jpetstore.web.actions.ListOrdersAction">
      <forward name="success" path="/WEB-INF/jsp/order/ListOrders.jsp"/>
      <forward name="failure" path="/error.jsp"/>
    </action>

    <action path="/actions/ViewOrder.action" name="OrderForm" scope="request" type="org.mybatis.jpetstore.web.actions.ViewOrderAction">
      <forward name="success" path="/WEB-INF/jsp/order/ViewOrder.jsp"/>
      <forward name="failure" path="/error.jsp"/>
    </action>

    <action path="/actions/EditAccountForm.action" name="AccountForm" scope="request" type="org.mybatis.jpetstore.web.actions.EditAccountFormAction">
      <forward name="success" path="/WEB-INF/jsp/account/EditAccountForm.jsp"/>
      <forward name="failure" path="/error.jsp"/>
    </action>

    <action path="/actions/EditAccount.action" name="AccountForm" scope="request" type="org.mybatis.jpetstore.web.actions.EditAccountAction">
      <forward name="success" path="/WEB-INF/jsp/catalog/Main.jsp"/>
      <forward name="failure" path="/error.jsp"/>
    </action>

    <action path="/actions/SignonForm.action" scope="request" type="org.mybatis.jpetstore.web.actions.SignonFormAction">
      <forward name="success" path="/WEB-INF/jsp/account/SignonForm.jsp"/>
    </action>

    <action path="/actions/Signon.action" name="AccountForm" scope="session" type="org.mybatis.jpetstore.web.actions.SignonAction">
      <forward name="success" path="/WEB-INF/jsp/catalog/Main.jsp"/>
      <forward name="failure" path="/WEB-INF/jsp/account/SignonForm.jsp"/>
    </action>

    <action path="/actions/Signoff.action" scope="session" type="org.mybatis.jpetstore.web.actions.SignoffAction">
      <forward name="success" path="/WEB-INF/jsp/catalog/Main.jsp"/>
    </action>
  </action-mappings>
</struts-config>

2. CatalogAction类

这是一个处理产品目录相关操作的类，它继承自Struts的Action类。

public class CatalogAction extends BaseAction {

  public ActionForward execute(
    ActionMapping mapping,
    ActionForm form,
    HttpServletRequest request,
    HttpServletResponse response) throws Exception {

    String categoryId = request.getParameter("categoryId");
    if (categoryId != null) {
      request.setAttribute("productList", CatalogFacade.getProductListByCategory(categoryId));
      request.setAttribute("category", CatalogFacade.getCategory(categoryId));
    }
    return mapping.findForward("success");
  }

}

3. CatalogActionForm类

这是一个Struts表单类，它用于存储从JSP页面提交的表单数据。

public class CatalogActionForm extends BaseActionForm {

  private String categoryId;

  public String getCategoryId() {
    return categoryId;
  }

  public void setCategoryId(String categoryId) {
    this.categoryId = categoryId;
  }

}

以上就是JPetStore中的一些Struts代码示例。
