我从使用xml配置的spring spring MVC应用程序转换到使用spring boot的java配置，我面临以下行为。无论我调用什么jsp页面，我总是得到404错误。控制器正在被击中，因为我可以在控制台上看到来自控制器打印机的sysout消息，但是没有显示视图。我已经明确地将调度程序映射设置为“/”而不是“/ *”，但它仍然无效。
我也看到并且不知道输出是否正常 “在名为'dispatcherServlet'的DispatcherServlet中找不到带有URI [/WEB-INF/jsp/profile6.jsp]的HTTP请求的映射”
通常我的意思是我已经注册了一个名为“dispatcher”而不是“dispatcherServlet”的调度程序。对我来说，似乎调度程序没有正确注册，因为onStartup中的sysout“STARTING THE CONFIGURATION”也没有打印。然后有一些“dispatcherServlet”能够从控制器打印出sysout，但视图没有找到。
这是弹簧启动主要功能：
@ComponentScan("org.syncServer")
@Configuration
@EnableWebMvc
@EnableAutoConfiguration
public class Application {
public static void main(String[] args) {
ApplicationContext ctx = SpringApplication.run(Application.class, args);
System.out.println("PRINTING the beans provided by Spring Boot:");
String[] beanNames = ctx.getBeanDefinitionNames();
Arrays.sort(beanNames);
for (String beanName : beanNames) {
System.out.println(beanName);
}
}
}
以下是按照maunual扩展WebApplicationInitializer类的Initilizer：
public class Initializer implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext)
throws ServletException {
System.out.println("STARTING THE CONFIGURATION");
AnnotationConfigWebApplicationContext mvcContext = new AnnotationConfigWebApplicationContext();
mvcContext.register(MVCConfig.class);
mvcContext.refresh();
// Register and map the dispatcher servlet
ServletRegistration.Dynamic dispatcher = servletContext.addServlet(
"dispatcher", new DispatcherServlet(mvcContext));
dispatcher.setLoadOnStartup(1);
dispatcher.addMapping("/");
}
}
MVC背景：
@Configuration
@ComponentScan(basePackages = "org.syncServer")
@EnableWebMvc
public class MVCConfig extends WebMvcConfigurerAdapter{
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/pdfs/**").addResourceLocations("/pdfs/");
registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
}
@Bean
public InternalResourceViewResolver internalResourceViewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/jsp/");
resolver.setSuffix(".jsp");
//resolver.setOrder(2);
resolver.setViewClass(JstlView.class);
return resolver;
}
}
我的控制器：
@Controller
public class ProfileController {
@RequestMapping(value = "/profile6", method=RequestMethod.GET)
public String profile6 (){
System.out.println("profile hellow6 has been hit");
return "profile6";
}
profile6查看jsp页面
