Question

我尝试在this tutorial的帮助下创建一个简单的Spring MVC项目但是当我部署它时显示404服务器错误。因为我是初学者，因为我是初学者，所以我无法弄清楚项目中有什么问题，尽管在这里和其他地方都要经过所有的答案。我将非常感谢你的帮助搞清楚。

这些是内容：

的pom.xml

while True:
    sides = int(input("How many sides on the shape are there? "))
    if sides in result:
        print(sides[result])
        break  # done, exit the loop
     print("You should enter a number between 3 and 8")

Web MVC配置（DeevigeWebMVCConfig.java）

package com.deevigeweb.config;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class DeevigeServletInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

    @Override
    protected Class<?>[] getRootConfigClasses() {
       return new Class[] {DeevigeWebMVCConfig.class};
    }

    @Override
    protected Class<?>[] getServletConfigClasses() {
       return null;
    }

    @Override
    protected String[] getServletMappings() {
       return new String[] {"/"};
    }

}

控制器（SearchViewController.java）

package com.deevigeweb.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

@EnableWebMvc
@Configuration
@ComponentScan({"com.deevigeweb"})
public class DeevigeWebMVCConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
         registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}

@Bean
public InternalResourceViewResolver viewResolver(){
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setViewClass(JstlView.class);
    resolver.setPrefix("/WEB-INF/views");
    resolver.setSuffix(".jsp");
    return resolver;
}

}

JSP （searchview.jsp）

package com.deevigeweb.controllers.webapp;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

public class SearchViewController {
    @RequestMapping(value="/",method=RequestMethod.GET)
    public ModelAndView doLanding(){
        return new ModelAndView("searchview");
    }
}

目录结构 project structure

Answer 1

也许添加尾部斜杠可以解决这个问题：

resolver.setPrefix("/WEB-INF/views/");

还在@Controller班级

上添加SearchViewController注释

Answer 2

在var myValue: Int = 1 if let test = myValue as? Int { print("IS INT") // hits here } else { print("NOT INT") }上添加班级var myValue: Float = 1.1 if let test = myValue as? Int { print("IS INT") } else { print("NOT INT") // hits here }注释。你错过了。

@Controller

现在，网址localhost:8080/deevigeweb/将返回SearchViewController页。

项目中不需要@Controller public class SearchViewController { @RequestMapping(value="/",method=RequestMethod.GET) public ModelAndView doLanding(){ return new ModelAndView("searchview"); } }，因为这是基于纯Java的配置。

基于Spring MVC注释的配置无法正常工作
