java - 构造函数抛出异常；

问题描述

我正在使用 tomcat 运行以下代码，但是当它运行并打开浏览器时，它显示以下错误我试图修复它，但我不明白出了什么问题

Error creating bean with name 'org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping': Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping]: Constructor threw exception; nested exception is java.lang.NoSuchMethodError: 'org.apache.commons.logging.Log org.springframework.core.log.LogDelegateFactory.getHiddenLog(java.lang.String)'

调度程序-servlet.xml

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean name="/" class="ir.maktab.HelloController"/>
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

web.xml

<web-app>
    <display-name>Archetype Created Web Application</display-name>
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>WEB-INF/dispatcher-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

</web-app>

你好控制器

public class HelloController extends AbstractController {
    

    @Override
    protected ModelAndView handleRequestInternal(HttpServletRequest request, HttpServletResponse response) throws Exception {
        return new ModelAndView("views/welcome");
    }
}

欢迎.jsp

<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
    <title>Title</title>
</head>
<body>
<h1>Welcome to my web app!!!</h1>
</body>
</html>

依赖项在 Maven 中是关于我使用的依赖项的版本吗？

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-framework-bom</artifactId>
                <version>${spring.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
