Question

我正在尝试使用dojo插件在Struts 2中构建一个应用程序，但我无法使其工作。 Index.jsp文件有3个文本框，使用名为类文件的注册验证进行验证。

的index.jsp：

<%@ taglib  uri="/struts-tags" prefix="s"%>
<%@ taglib uri="/struts-dojo-tags" prefix="d"%>
<html>
<head>
<d:head/>
</head>
<body>
<marquee>Registration Form.............</marquee>

<s:form action="register">
<s:textfield name="name" label="Username"></s:textfield>
<s:textfield name="email" label="Email ID"></s:textfield>
<s:password name="password" label="Password"></s:password>
<d:submit >
</d:submit>
</s:form>

</body>
</html>

Register.java：

package example;

import com.opensymphony.xwork2.ActionSupport;

public class Register extends ActionSupport{
private String name,password,email;

//setters and getters

public String execute(){
    return "success";
}
}

注册-validation.xml中：

<validators>

<field name="name">
<field-validator type="requiredstring">
<message>Name can't be blank</message>
</field-validator>
</field>

<field name="email">
<field-validator type="requiredstring">
<message>Email ID can't be blank</message>
</field-validator>
<field-validator type="email">
<message>Please enter a valid email ID</message>
</field-validator>
</field>

<field name="password">
<field-validator type="requiredstring">
<message>Password can't be blank</message>
</field-validator>
<field-validator type="stringlength">
<param name="minLength">5</param>
<param name="maxLength">10</param>
<message>Password can't be less than 5 or greater than 10</message>
</field-validator>

</field>



</validators>

Sturts.xml：

<?xml version="1.0" encoding="UTF-8" ?>

    "http://struts.apache.org/dtds/struts-2.5.dtd">

我有以下图书馆： -List item Struts 2 core 2.3.15

列出项目Struts 2 dojo插件2.3.24

我希望这些信息足够。谢谢任何回复：）

Answer 1

你有两个不同版本的dojo插件库。版本2.3中不推荐使用Dojo插件。清理WEB-INF/lib：

struts2的-道场-插件-2.3.1.2.jar
struts2的-道场-插件-2.1.8.jar

如果您使用的是Struts 2.3.24，则版本应该在plugin-之后。请参阅this回答，了解您可以使用哪个库而不是dojo插件。

带有DOJO插件的Struts 2.3.15不起作用
