Spring MVC 配置

1， 

RootConfig用來配置ContextLoadListener

 1 @Configuration
 2 //@Import(DataConfig.class)
 3 @ComponentScan(basePackages={"spittr"}, 
 4     excludeFilters={
 5         @Filter(type=FilterType.CUSTOM, value=WebPackage.class)
 6     })
 7 public class RootConfig {
 8   public static class WebPackage extends RegexPatternTypeFilter {
 9     public WebPackage() {
10       super(Pattern.compile("spittr\\.web"));
11     }    
12   }
13 }

RootConfig

 

WebConfig 用來配置DispatcherServlet

 1 @Configuration
 2 @EnableWebMvc
 3 @ComponentScan("spittr.web")
 4 public class WebConfig extends WebMvcConfigurerAdapter {
 5 
 6   @Bean
 7   public ViewResolver viewResolver() {
 8     InternalResourceViewResolver resolver = new InternalResourceViewResolver();
 9     resolver.setPrefix("/WEB-INF/views/");
10     resolver.setSuffix(".jsp");
11     return resolver;
12   }
13   
14   @Override
15   public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
16     configurer.enable();
17   }
18   
19   @Override
20   public void addResourceHandlers(ResourceHandlerRegistry registry) {
21     // TODO Auto-generated method stub
22     super.addResourceHandlers(registry);
23   }
24 
25 }

WebConfig

 

建立上面2個context

public class SpitterWebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
  
  @Override
  protected Class<?>[] getRootConfigClasses() {
    return new Class<?>[] { RootConfig.class };
  }

  @Override
  protected Class<?>[] getServletConfigClasses() {
    return new Class<?>[] { WebConfig.class };
  }

  @Override
  protected String[] getServletMappings() {
    return new String[] { "/" };
  }

}

SpitterWebInitializer

 

若是發現jsp中的對象展現沒能正常工做，多是web.xml沒有配置到比較新的schema，應該是：

1 <?xml version="1.0" encoding="UTF-8"?>
2 <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
3          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
4          xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
5          version="3.1">
6 
7 
8 
9 </web-app>
