我试图运行一个示例 Spring 应用程序,但我无法配置它。我搜索了我的问题,但对我来说一切似乎都很好。

Web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
    <display-name>Spring Hello World</display-name>
    <welcome-file-list>
        <welcome-file>/</welcome-file>
    </welcome-file-list>

    <servlet>
        <servlet-name>springDispatcher</servlet-name>
        <servlet-class>
            org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
      <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring-context.xml</param-value>
        </init-param>        
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springDispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

com.fyp.ptma.controller 中的控制器文件

@Controller
public class HelloWorldController {

    @RequestMapping("/")
    public String hello() {
        return "hello";
    }

    @RequestMapping(value = "/hi", method = RequestMethod.GET)
    public String hi(@RequestParam("name") String name, Model model) {
        String message = "Hi " + name + "!";
        model.addAttribute("message", message);
        return "hi";
    }

}

弹簧上下文.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <context:component-scan base-package="com.fyp.ptma.controller" />
    <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>

WEB-INF/views/hello.jsp 中的 hello.jsp

<html>
<head>
<title>Home</title>
</head>
<body>
    <h1>Hello World!</h1>

<hr/>

    <form action="hi">
        Name: <input type="text" name="name"> <input type="submit" value="Submit">
    </form>

</body>
</html>

位于 conf/Catalina/localhost/ptma.xml 的 tomcat 中的 ptma.xml 文件

<?xml version="1.0" encoding="utf-8"?>
<Context docBase="/Volumes/DataDrive/FYP/TestMonkeyAppWeb‬/WebContent‬‪" debug="0" crossContext="true" reloadable="true" >   
</Context>

我以 localhost:8080/ptma/ 身份访问我的项目,但它说 HTTP 状态 404 和 tomcat 日志似乎工作正常。

web.xml 中的欢迎文件映射似乎不正确。将其更改为 index.jsp 之类的内容,在应用程序的根目录中创建一个具有此名称的文件并重定向到您的第一个控制器。
