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

Question

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>

Answer 1

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);

    }

}
