    public city ServletContext. Defines a set of ways and means that a servlet uses to display itself in its servlet container, such as getting the MIME type of a file, sending requests, or preparing a log file. The context is reviewed monthly for the Java Virtual Machine “Web Application”.


    No performance difference stated, at best request.getSession() implicitly creates an HTTP session object if it’s not already ustriplets So if it’s not yet complete, fetching the servlet structure in the session may take longer every few nanoseconds if the workbench hasn’t been created yet. Also

    The returned context is free. These possibilities are only practical, and how you perceive the situation depends on the context 😉 at the moment you are in.

    How can I get ServletContext and ServletConfig object in a spring bean?

    Implement the Spring *Aware interfaces for these ServletContextAware and ServletConfigAware interfaces.Using the @Autowired annotation with coffee bean variables like ServletContext and ServletConfig .

    In a called method, if you are using a servlet’s service() (for example, doGet(), doPost(), etc.) ) Ski drive ), this time just use the resulting getServletContext() method. Other ways to unnecessarily add symbols to a company code.

    @Overrideprotected void doGet(HttpServletRequest, HttpServletResponse) ServletContext equals getServletContext(); // ...

    If you need to sit in a servlet method, init(servletconfig), then the deprecated getServletContext() isn’t there yet, unless you is fine . initialization(configuration). You need to get it from ServletConfig.

    @Overridepublic void init(ServletConfig config) structure ServletContext = config.getServletContext(); . . ; .// ....Many

    but it’s better to bypass init() instead. In A high quality servlet will usually never need an override to achieve init(ServletConfig).

    how to get servletcontext in servlet

    @Overridepublic void initialization() context ServletContext = getServletContext(); . - . .// ....

    If you’re not too savvy with servlets, but for example you’re missing a filter like the legacy method getServletContext() and you have at best ServletRequest handy , buyers could get it from there.

    @Overridepublic nullify doFilter(ServletRequest, ServletResponse, FilterChain) context servletcontext = request.getServletContext(); . . . . . . .// ....This

    Please note that this is new with Servlet 3.0. They must have already helped you log out of a session before.

    @OverridedoFilter(ServletRequest, ServletResponse, FilterChain) public error context servletcontext = request.getSession().getServletContext(); . . . . . .// ....

    It’s not good if you’re afraid of unnecessary session evolution. Hence the introduction of ServletRequest#getServletContext() – even though you can just drag it from FilterConfig (hey, there’s another way!) to another.

    Private FilterCon configurationfig;@Crushuseless public initialization (FilterConfig config) this.config is the config;@Crushpublic void doFilter(ServletRequest, ServletResponse, FilterChain)   context ServletContext = config.getServletContext(); . , . .// ....Later

    How can you get the information about one servlet context in another servlet?

    It can be obtained using the getServletContext() method. The ServletContext has a single “application” scope and can also be used to pass information connecting servlets in the same application through the setAttribute(“name”, object) and getAttribute(“name) handlers.

    and where there are HTTP session listeners where your company deletes the session, among other things. There is no other way to use context servlet other than HttpSession#getServletContext().


    @Overridepublic void sessionDestroyed(HttpSessionEvent event) Context ServletContext = event.getSession().getServletContext(); . ! ! . .// ....

    You don’t have to worry about creating unnecessary periods here, because this period was created beforehand. Note that there is no ServletRequest at any time, as this is not necessarily related to an active HTTP request during a machine-side session timeout.

    Finally, there is also ServletContext#getContext() which returns the ServletContext of another web application to implement the same server (this only works if the server is configured to support cross contextual access to the corresponding web application).

    ServletContext otherContext = context.getContext("/otherContextPath");

    But to get started, the current ServletContext is already required, which you should always know how to get.
