Question

我已经开始在基于Maven的项目中使用Spring MVC。我的项目目录结构是 https://laravel.com/docs/5.4/validation#conditionally-adding-rules

web.xml的内容

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns="http://www.springframework.org/schema/beans"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                           http://www.springframework.org/schema/beans/spring-beans.xsd
                           http://www.springframework.org/schema/context
                           http://www.springframework.org/schema/context/spring-context.xsd
                           http://www.springframework.org/schema/mvc
                           http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <context:component-scan base-package="com.web.controller"/>
    <bean name="properties" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
        <property name="locations">
            <list>
                <value>/WEB-INF/config.properties</value>
            </list>
        </property>
    </bean>
    <mvc:resources mapping="/css/**" location="/css/"/>
    <mvc:resources mapping="/js/**" location="/js/"/>
    <mvc:annotation-driven/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

servetContext的内容是

@Controller
public class LoginController {
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public String signIn() {
        return "sign-in";
    }
}

在LoginController中，我定义了一个将处理初始HttpRequest

的方法

defined( 'ABSPATH' ) or die( 'Error: 120' );
/**
 * Check if WooCommerce is active
 **/
if ( in_array( 'woocommerce/woocommerce.php', apply_filters( 'active_plugins', get_option( 'active_plugins' ) ) ) ) {
    /**
     * Register a custom menu page.
     */
    function wpdocs_register_my_custom_menu_page() {
        add_menu_page(
            __( 'Amazon Affiliate Dashboard', 'textdomain' ),
            'Amazon Affiliate',
            'manage_options',
            'amazon-affiliate/dashboard.php',
            '',
            plugins_url( 'amazon-affiliate/assets/images/icon2.png' ),
            6
        );
    }
    add_action( 'admin_menu', 'wpdocs_register_my_custom_menu_page' );
}else{

}

当我使用

请求登录页面时

它给我404找不到错误。你能告诉我在这里为整个设置做了什么错误。

Answer 1

您应该有一个索引页面，直接放在webapp文件夹下，用于每个Web应用程序，这是访问应用程序时加载的第一个页面。

将此内容包含在您的web.xml中

 <welcome-file-list>
    <welcome-file>redirect.jsp</welcome-file>
</welcome-file-list>

重定向页面（jsp）可以是：

  <%@page contentType="text/html" pageEncoding="UTF-8"%>
  <% response.sendRedirect("signin"); %>

然后你可以将“signin”映射到spring的indexcontroller。哪个会将您的“登录”页面视为视图

I have done mistake one mistake in Parent POM.xml, where i have defined scope as provided for spring-mvc so that it is not packaged with in lib folder. That is why dispatcher class was not found. I have checked the log and solved the issue. Thank you for all.
