java - 每当我尝试部署 Spring MVC 应用程序(从 Intellij 或通过将 war 文件复制到 webapps)时，Tomcat 7 都会显示状态 404

Question

当我尝试部署(任何)Spring MVC 应用程序时，Tomcat 7 始终显示状态 404 资源不可用。此外，当我转到 localhost:8080 时它显示相同的消息，即使我重新启动了 Windows。 (非 MVC 应用程序仍然可以正常使用)。

这是我的 web.xml:{ http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

   <display-name>Spring MVC Hello World</display-name>
   <welcome-file-list>
          <welcome-file>/</welcome-file>
   </welcome-file-list>

   <servlet>
          <servlet-name>spring</servlet-name>
          <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
          <load-on-startup>1</load-on-startup>
   </servlet>

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

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

spring-servlet.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"

   http://www.springframework.org/schema/context              http://www.springframework.org/schema/context/spring-context.xsd">

   <context:component-scan base-package="hr.altima"/>

</beans>

AppConfig.java:

@Configuration
@EnableWebMvc
public class AppConfig extends WebMvcConfigurerAdapter{

@Bean
public InternalResourceViewResolver viewResolver() {
    InternalResourceViewResolver internalResourceViewResolver = new InternalResourceViewResolver();
    internalResourceViewResolver.setPrefix("/");
    internalResourceViewResolver.setSuffix(".jsp");
    return internalResourceViewResolver;
}

@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
    configurer.enable();
}

这只是一个简单的 Controller :

@ Controller 公共(public)类 HomeController {

@RequestMapping(value = "/")
public String home() {
    return "test";
}

尝试将您的 View 解析器配置更改为此，我认为您设置错误。

@Bean
public InternalResourceViewResolver viewResolver() {
    InternalResourceViewResolver internalResourceViewResolver = new InternalResourceViewResolver();
    internalResourceViewResolver.setPrefix("/WEB-INF/");
    internalResourceViewResolver.setSuffix(".jsp");
    return internalResourceViewResolver;
}
