, так как заголовок говорит, что я получаю сообщение об ошибке "[org.springframework.web.servlet.PageNotFound] (по умолчанию task-1) Нет сопоставления для GET / ProjectFE /", как мне это исправить?Также нет ошибок в коде.

вот мой мой код:

файл web.xml-

homepage.java file:

        @RequestMapping(value="/", method=RequestMethod.GET)
    public String home()
    {
       return "homepage";
    }

 }

После запуска кода на сервере вот что я получаю:

Прежде всего упорядочите ваш web.xml следующим образом 

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">


    <!-- Processes application requests -->
    <servlet>
        <servlet-name>appServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>

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

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>
            WEB-INF/spring-config.xml
        </param-value>
    </context-param>
   <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
</web-app>

Поскольку вы определяете contex-param, вам не нужно использовать init-param один и тот же XML-файл.Теперь немного измените значение spring-config.xml 

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

<mvc:annotation-driven/>

<resources mapping="/resources/**" location="/resources/" />

<beans:bean 
 class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <beans:property name="prefix" value="/Views/" />
    <beans:property name="suffix" value=".jsp" />
 </beans:bean>

  <context:component-scan    base-package="controller" />        
 </beans:beans>

. Внимательно посмотрите на строку <beans:property name="prefix" value="/Views/" />.Ваше имя папки Views, но вы определили view.Вот почему, возможно, вы получаете сообщение об ошибке.

Покажите, если это сработает.
