Question

我的春季项目，配置基于java代码，当我尝试通过eclipse运行时，它返回404错误。下面我列出我的配置类。任何人都可以指出我的错误是什么？尽管工作了一段时间，我什么也没弄清楚。在eclipse控制台中，不会显示任何错误或异常。

应用程序的第二个问题，它与hibernate有关。我使用pgadmin3（来自postgresql）创建一个数据库，当我运行应用程序时，它应该根据我的实体在数据库上创建表，但是它没有发生（没有显示与此相关的错误，太）。

WebAppInitializer.java

@Order(value=1)
public class WebAppInitializer implements WebApplicationInitializer {

    @SuppressWarnings("resource")
    @Override
    public void onStartup(ServletContext container) {
      // Create the 'root' Spring application context
      AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
      rootContext.register(WebAppConfig.class);

      // Manage the lifecycle of the root application context
      //container.addListener(new ContextLoaderListener(rootContext));

      // Create the dispatcher servlet's Spring application context
      AnnotationConfigWebApplicationContext dispatcherContext = new AnnotationConfigWebApplicationContext();
      dispatcherContext.register(DispatcherConfig.class);

      // Register and map the dispatcher servlet
      ServletRegistration.Dynamic dispatcher = container.addServlet("dispatcher", new DispatcherServlet(dispatcherContext));
      dispatcher.setLoadOnStartup(1);
      dispatcher.addMapping("/");
    }

}

WebAppConfig.java

@EnableWebMvc
@ComponentScan(value="org.webapp")
@Configuration
public class WebAppConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/css/**").addResourceLocations("/css/").setCachePeriod(31556926);
        registry.addResourceHandler("/css/**").addResourceLocations("/fonts/").setCachePeriod(31556926);
        registry.addResourceHandler("/img/**").addResourceLocations("/image/").setCachePeriod(31556926);
        registry.addResourceHandler("/js/**").addResourceLocations("/js/").setCachePeriod(31556926);
    }

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

}

DispatcherConfig.java

@Controller
@Import(WebAppConfig.class)
public class DispatcherConfig {

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

}

Answer 1

一个错误肯定是您使用DispatcherConfig而不是@Controller注释@Configuration

你提到的第二个问题可能是因为你已经设定了 hibernate.hbm2ddl.auto=update代替hibernate.hbm2ddl.auto=create-drop

spring项目执行时有多个问题
