java我的程序没有运行，虽然它没有给我错误
我是Spring mvc的初学者，我使用maven在eclipse中创建了一个webapp项目，它是用java纯代码配置的。项目中没有错误，但当我运行它时，它不工作，它给我HTTP 404错误[/spring calculator/test]不可用。 spring calculator是我的名字 测试是控制器url映射
类计算器应用程序初始化器取代web。xml配置中的xml
public class CalculatorApplicationInitializer implements WebApplicationInitializer {
public void onStartup(ServletContext servletContext) throws ServletException {
AnnotationConfigWebApplicationContext WebApplicationContext = new
AnnotationConfigWebApplicationContext();
WebApplicationContext.register(CalculatorAppContext.class);
// create servlet Dispacher object
DispatcherServlet dispatcherServlet = new
DispatcherServlet(WebApplicationContext);
//registred dispatcher servlet with servlet context
ServletRegistration.Dynamic myCustomDispatcherServlet =
servletContext.addServlet("MyDispatcherServlet",dispatcherServlet);
myCustomDispatcherServlet.setLoadOnStartup(1);
myCustomDispatcherServlet.addMapping("/");
}
}
类CalculatorAppContext替换应用程序上下文。xml配置中的xml
@EnableWebMvc
@Configuration
@ComponentScan(basePackages = "com.home.lc.controllers")
public class CalculatorAppContext {
// setup my view resolver
@Bean
public InternalResourceViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/WEB-INF/view/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
}
That's the controller returning vue
@Controller
public class TestController {
@RequestMapping("/test")
public String SayHello() {
return "hi" ;
}
}
