Accessing Spring beans from servlet filters and tags

Question

I can access Spring beans in my Servlets using

WebApplicationContext springContext = 
    WebApplicationContextUtils.getWebApplicationContext(getServle         


        

Answer 1

For filters - use Filter.init():

public void init(FilterConfig config) {
    WebApplicationContext springContext = 
        WebApplicationContextUtils.getWebApplicationContext(config.getServletContext());
}

For tags - use TagSupport.pageContext (note that it's not available in SimpleTagSupport):

WebApplicationContext springContext = 
    WebApplicationContextUtils.getWebApplicationContext(pageContext.getServletContext());
