Spring MVC 根容器和子容器

整合 spring mvc 根容器和子容器 

public class TestWebInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {
    //根容器
    @Override
    protected Class<?>[] getRootConfigClasses() {
        return new  Class<?>[]{TestRootConfig.class};
    }
    //子容器
    @Override
    protected Class<?>[] getServletConfigClasses() {
        return new Class<?>[]{TestAppConfig.class};
    }
    //获取dispatcherservlet映射信息
    //拦截所有请求 (静态资源,js,css,png) 不包括.jsp
    //jsp解析 是tomcat的jspy引擎解析
    @Override
    protected String[] getServletMappings() {
        return new String[]{"/"};
    }
}

根容器  

    //对非controller层进入bean注入
@ComponentScan(value = "cn.qin",excludeFilters ={
        @ComponentScan.Filter(type = FilterType.ANNOTATION,classes = {Controller.class}) //负责非contrller 层的扫描 
},useDefaultFilters = false)
public class TestRootConfig {

}

子容器  

@ComponentScan(value = "cn.qin",includeFilters ={
        @ComponentScan.Filter(type = FilterType.ANNOTATION,classes = {Controller.class}) //负责contrllor 的扫描
},useDefaultFilters = false)
public class TestAppConfig {
}
