Question

我使用带有struts 2 xml字段验证（tomcat7）的netbeans 8来创建一个Web应用程序。形成。当我单击提交按钮而不填写表单时，将显示成功页面，没有错误将表单留空。我错过了将LoginAction-validation.xml连接到表单的步骤吗？也许我需要更新插件？我在Libraries文件夹中有以下内容用于表单验证：

Struts2 Core 2.3.15 - xwork-core-2.3.15.3.jar

Struts2 Core 2.3.15 - struts2-core-23.15.3.jar

LoginAction.java

package login;

import com.opensymphony.xwork2.ActionSupport;

public class LoginAction extends ActionSupport {

    public String getNotes() {
        return notes;
    }

    public void setNotes(String notes) {
        this.notes = notes;
    }

    public String getOperatingSystem() {
        return operatingSystem;
    }

    public void setOperationSystem(String operatingSystem) {
        this.operatingSystem = operatingSystem;
    }

    public String getVersion() {
        return version;
    }

    public void setVersion(String pass) {
        this.version = version;
    }
    String operatingSystem;
    String version;
    String notes;

    @Override
    public String execute(){
          return "SUCCESS";
    }
}

的index.jsp

<!DOCTYPE html>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib uri="/struts-tags" prefix="s" %>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

                <s:textfield label="Version" name="version"/>
                 <s:textfield label="Notes" name="notes"/>
                <s:submit cssClass="btn btn-primary"/>
        </s:form>
    </body>
</html>

    <body>
        <h1>Error!</h1>
    </body>
</html>

Answer 1

正如您在the Apache DTD directory中看到的那样，没有像xwork-validator-2.3dtd这样的东西（扩展中也有拼写错误）。最新的xwork-validator是1.0.3，它是你应该使用的那个：

<!DOCTYPE validators PUBLIC "-//Apache Struts//XWork Validator 1.0.3//EN"
          "http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd">

同时提醒始终使用相同版本的库，例如2.3.15.3（或更好2.3.16.1）无处不在

Struts2表单验证不起作用
