Spring的基于Java的配置项目显示404
Spring的基于Java的配置项目显示404
提问于 2018-10-16 23:02:23
我最近创建了Spring maven项目，我正在使用纯基于java的配置，在运行相同的配置时，我遇到了404。我在这里一无所知。
AppInitializer (web.xml更换)
package com.mzk.mascot.configuration;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;
/**
*
* @author Ossu
*/
public class WebApplicationBootstrapper implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext sc) throws ServletException {
AnnotationConfigWebApplicationContext applicationContext=new AnnotationConfigWebApplicationContext();
AnnotationConfigWebApplicationContext dispatcherContext=new AnnotationConfigWebApplicationContext();
applicationContext.register(SpringBeanContainer.class);
dispatcherContext.register(DispatcherServletConfiguration.class);
ContextLoaderListener contextLoaderListener=new ContextLoaderListener(applicationContext);
sc.addListener(contextLoaderListener);
DispatcherServlet dispatcherServlet = new DispatcherServlet(dispatcherContext);
ServletRegistration.Dynamic dispatcher = sc.addServlet("dispatcher", dispatcherServlet);
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}
}app Spring bean容器(-context.xml替换)
package com.mzk.mascot.configuration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
/**
*
* @author Ossu
*/
@Configuration
@EnableWebMvc
@ComponentScan({"com.mzk.mascot.controller"})
public class SpringBeanContainer {
}最终调度程序-servlet配置文件
package com.mzk.mascot.configuration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.ContentNegotiationConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
/**
*
* @author Ossu
*/
@Configuration
@EnableWebMvc
@ComponentScan({"com.mzk.mascot.controller"})
public class DispatcherServletConfiguration implements WebMvcConfigurer {
@Bean
ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("WEB-INF/view/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
ResourceHandlerRegistration handlerRegistration = registry.addResourceHandler("/resources/**");
handlerRegistration.addResourceLocations("/resources/");
}
@Override
public void configureContentNegotiation(ContentNegotiationConfigurer configurer) {
configurer.favorPathExtension(false);
}
}在此配置之前，它缺省情况下通过访问http://localhost:8084/Mascot/.来呈现index.html在添加了这三个类之后，它显示404，我仍然不能弄清楚，如果我在任何类的任何地方出错了，请告诉我并纠正我。

您所需要做的就是更新DispatcherServletConfiguration类。
首先更新addResourceHandlers()方法并注册静态HTML页面处理程序：
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
registry.addResourceHandler("/*.html").addResourceLocations("/WEB-INF/static/");
}然后覆盖从/(根)转发到/index.html的addViewControllers()方法
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("forward:/index.html");
}最后，将静态文件移动到WEB-INF/ index.html文件夹中。
注意：如果您的index.html页面只重定向到其他地方(例如在/welcome上)，那么您可以直接进行转发：
registry.addViewController("/").setViewName("forward:/welcome");页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
