Question

在给出任何回复之前，请自行测试。因为我已经尝试了所有具有不同spring框架版本的IDE。我已经尝试过4.0.4到最新的4.2。但从来没有得到正确的答案。请帮帮我，指导我。提前谢谢。

这是我的控制器类，HelloWorld

package controllers;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller

public class HelloWorld {
    @RequestMapping("/hi")
    public ModelAndView hello(){
        ModelAndView modelAndView= new ModelAndView("index");
        modelAndView.addObject("msg", "Hi there......");
        return modelAndView;
    }
}

这是我的弹簧配置文件

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

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

    <bean id="viewResolver" class="org.springframework.web.servlet.InternalResourceViewResolver">
    <property name="prefix">

    </property>
    <property name="suffix">
        <value>.jsp</value>
    </property>
 </bean>

</beans>

这是我的web.xml文件
