SpringMVC JavaConfig配置

以前通用的SpringMVC配置方法是使用web.xml加载SpringMVC以及使用spring的配置文件加载bean servlet3.0以后可以直接用Java的方式配置springmvc

初始化

继承AbstractAnnotationConfigDispatcherServletInitializer类，并定义映射，spring配置类，root配置

public class MyWebAppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer { protected Class<?>[] getRootConfigClasses() { return new Class<?>[]{RootConfig.class}; } protected Class<?>[] getServletConfigClasses() { return new Class<?>[]{WebConfig.class}; } protected String[] getServletMappings() { return new String[]{"/"}; } protected Filter[] getServletFilters() { HiddenHttpMethodFilter hiddenHttpMethodFilter = new HiddenHttpMethodFilter(); return new Filter[]{hiddenHttpMethodFilter}; } }

定义WebConfig

@Configuration @EnableWebMvc @ComponentScan(basePackages = "com.gggg") public class WebConfig extends WebMvcConfigurerAdapter{ @Bean public ViewResolver viewResolver(){ InternalResourceViewResolver resolver = new InternalResourceViewResolver(); resolver.setPrefix("/WEB-INF/views/"); resolver.setSuffix(".jsp"); return resolver; } @Override public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer){ configurer.enable(); } }

定义RootConfig

@Configuration @ComponentScan(basePackages = "com.ggg",excludeFilters = {@ComponentScan.Filter(type= FilterType.ANNOTATION,value = EnableWebMvc.class)}) public class RootConfig { }
