用一個類來存放applicationContext：
public class ContextHolder {
? private final static ContextHolder instance = new ContextHolder();
? private ApplicationContext ac;
? private ContextHolder() {
? }
? public static ContextHolder getInstance() {
??? return instance;
? }
? public synchronized void setApplicationContext(ApplicationContext ac) {
??? this.ac = ac;
? }
? public ApplicationContext getApplicationContext() {
??? return ac;
? } ?
}
然后寫一個servlet，繼承自org.springframework.web.context.ContextLoaderServlet，并配置web.xml，讓它在tomcat啟動時自動運行。然后在它的init方法中，加入如下的代碼：
WebApplicationContext context = WebApplicationContextUtils.
??? getWebApplicationContext(this.getServletContext());
ContextHolder.getInstance().setApplicationContext(context);
