基于代码的Servlet Initializer的行为与web.xml不同

Question

使用AbstractAnnotationConfigDispatcherServletInitializer将基于Spring xml的servlet配置转换为基于代码/注释的初始化时，我遇到了一个奇怪的问题

编辑： 代码构建正常，但请求映射无法正常工作。在基于代码的配置中，如果我将请求映射到＆＃34; / *" and not "/", however as i want to serve up JSP pages with a view resolver I cant use "/ *＆＃34;它将仅处理请求。因为它阻止了它正常运作。

谁能看到我做错了什么？ Spring版本是3.2.4

基于XML的servlet初始化

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

     http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
     version="3.0">

    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>

基于代码的servlet初始化

public class AppInitializer extends AbstractAnnotationConfigDispatcherServletInitializer {

@Override
protected Class<?>[] getRootConfigClasses() {
    return null;
}

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

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

@Override
public void customizeRegistration(ServletRegistration.Dynamic registration) {
    registration.setInitParameter("throwExceptionIfNoHandlerFound", "true");
    registration.setInitParameter("dispatchOptionsRequest", "true");
    registration.setLoadOnStartup(1);
}

}
