javabeans 相关问题

javabean是一个自定义类，通常表示真实数据，并通过公共getter和setter方法封装私有属性。例如，用户，产品，订单等。

我现在正在使用 JSP，但我的 bean 有一些问题。我有这样的消息： javax.servlet.jsp.JspException：无法在名称段下找到 bean 支柱配置：我现在正在使用 JSP，但我在使用 Bean 时遇到了一些问题。我有这样的消息： javax.servlet.jsp.JspException：无法在名称段下找到 bean Struts 配置： <?xml

JSP，或者您遇到验证错误并将此 JSP 配置为 input。在最后一种情况下，您应该在表单的 validate() 方法中初始化集合。还有另一种方式通过 html:select 为 html:optionsCollection 提供选项。 <html:optionsCollection property="segments" label="name" value="id" />

在Struts中获取选中的单选按钮索引

我在 Struts 1 表单上有一些单选按钮：我在 Struts 1 表单上有一些单选按钮： <input type="radio" name="productId" value="31415" /> <input type="radio" name="productId" value="31416" /> 然后在 Action 类中我可以很好地从表单中获取值。例如，如果我选择第一个单选按钮，则 myForm.getProductId() 返回 31415。问题： Struts 1 中是否有一种方法可以告诉通过索引选择哪个输入字段，同时保留当前功能？（在最坏的情况下我知道我可以创建一个新的隐藏字段，其中包含所选的单选按钮并从 JavaScript 更新该字段，但我也想避免这种方式。）说明：单选按钮是基于集合创建的，但由于某种原因，集合的元素有时没有产品 ID，因此如果有多个这样的元素，那么我无法判断选择了哪个单选按钮。但我想知道即使在这些情况下，如何提高系统的容错能力。（我对集合中的元素没有权力，它们来自网络服务。）您可以使用索引属性作为输入字段的索引名称。对于索引属性，BeanUtils.populate() 使用请求参数的名称来确定调用正确的 setter 方法 ActionForm 使用索引名称 <input type="radio" name="productId[0]" value="31415" /> <input type="radio" name="productId[1]" value="31416" /> 定义索引属性 private String[] productId; public String getProductId(int index) { return productId[index]; } public void setProductId(int index, String productId) { productId[index] = productId; } public String[] getProductId( ) { return productId; }

JSP，或者您遇到验证错误并将此 JSP 配置为 input。在最后一种情况下，您应该在表单的 validate() 方法中初始化集合。还有另一种方式通过 html:select 为 html:optionsCollection 提供选项。 <html:optionsCollection property="segments" label="name" value="id" />
