将跟踪模式设置为cookie，以删除附加的会话ID，而无需使用web.xml
问题内容：
我正在设置一个完全基于Java的Spring应用程序，没有xml配置：
public class WebApp extends AbstractAnnotationConfigDispatcherServletInitializer {
@Override
protected Class<?>[] getRootConfigClasses() {
return null;
}
@Override
protected Class<?>[] getServletConfigClasses() {
return new Class<?>[]{WebMvcConfigurer.class};
}
@Override
protected String[] getServletMappings() {
return new String[]{"/"};
}
和
@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { mypackages })
public class WebMvcConfigurer extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**").addResourceLocations("/static-assets/");
}
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/WEB-INF/views/");
viewResolver.setSuffix(".jsp");
return viewResolver;
}
我该放在哪里，它曾经在我的web.xml中？
<session-config>
<!-- Disables URL-based sessions (no more 'jsessionid' in the URL using Tomcat) -->
<tracking-mode>COOKIE</tracking-mode>
</session-config>
问题答案：
您可以按照以下步骤进行操作
public class WebConfig implements WebApplicationInitializer {
@Override
public void onStartup(ServletContext servletContext)
throws ServletException {
HashSet<SessionTrackingMode> set = new HashSet<SessionTrackingMode>();
set.add(SessionTrackingMode.COOKIE);
servletContext.setSessionTrackingModes(set);
}
}
