我需要在没有 web.xml 的情况下配置 Spring Mvc。仅使用 java 配置
我的网络配置
@EnableWebMvc
@Configuration
@ComponentScan(basePackages = "controllers.web")
@Import({PersistenceJPAConfig.class})
public class WebConfig extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
@Override
public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
configurer.enable();
}
@Bean
public ViewResolver internalResourceViewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/view/jsp");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
}
我的 WebInitializer
public class WebInitializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext ctx = new AnnotationConfigWebApplicationContext();
ctx.register(WebConfig.class);
servletContext.addListener(new ContextLoaderListener(ctx));
ctx.setServletContext(servletContext);
Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(ctx));
servlet.setLoadOnStartup(1);
servlet.addMapping("/");
}
}
我的 Controller
@Controller
@RequestMapping("/")
public class MainController {
@Autowired
BusRepository busRepository;
@RequestMapping(method = RequestMethod.GET)
public String index(ModelMap model) {
StringBuilder sb = new StringBuilder("<br>");
busRepository.findAll().forEach(it->sb.append(it.toString()).append("<br>"));
model.put("msg", sb.toString());
return "index";
}
}
我的index.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Spring MVC</title>
</head>
<body>
<h4>Spring MVC</h4>
<span class="blue">${msg}</span>
</body>
</html>

我通过 power shell 检查了服务器的工作情况(有效)。 当我通过应用程序启动服务器时，我得到“HTTP Status 404 – Not Found” 我试过其他网址。 war 文件已组装。 我该如何解决这个问题？
提前致谢
最佳答案
您应该在@RequestMapping 中指定value。
关于java - Spring MVC。 Tomcat 。 HTTP 状态 404 – 未找到，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47677410/
