struts.xml 配置页面

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

<!DOCTYPE struts PUBLIC
        "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN"
        "http://struts.apache.org/dtds/struts-2.5.dtd">

<struts>
    <constant name="struts.ognl.allowStaticMethodAccess" value="true"></constant>
    <constant name="struts.devMode" value="true"></constant>
    <constant name="struts.enable.DynamicMethodInvocation" value="true"></constant>
    <constant name="struts.configuration.xml.reload" value="true"></constant>
    <package name="action" extends="struts-default" strict-method-invocation="false">
        <action name="userAction" class="com.chenx.action.UserAction">
            <result name="input">index.jsp</result>
            <result name="success">show.jsp</result>
        </action>
    </package>


</struts>

UserAction类

package com.chenx.action;

import com.opensymphony.xwork2.ActionSupport;

public class UserAction extends ActionSupport {
    private static final long serialVersionUID=1L;
    private String name;
    private String password;
    
    public String execute() throws Exception{
        return SUCCESS;
    }
    public void setName(String name) {
        this.name = name;
    }

    public void setPassword(String password) {
        this.password = password;
    }

    public String getName() {
        return name;
    }

    public String getPassword() {
        return password;
    }


}

UserAction-validation.xml 验证配置注意DOCTYPE的变化因为改变了网址

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE validators PUBLIC
        "-//Apache Struts//XWork Validator 1.0.3//EN"
        "http://struts.apache.org/dtds/xwork-validator-1.0.3.dtd">
<validators>
    <!-- 验证用户名 -->
    <field name="name">
        <field-validator type="requiredstring">
            <message>请输入用户名</message>
        </field-validator>
    </field>
    <!-- 验证密码 -->
    <field name="password">
        <field-validator type="requiredstring">
            <message>请输入密码</message>
        </field-validator>
    </field>
</validators>
