如何将2 gwt module_x.module_x.nocache.js嵌入到html文件中?

<script language="javascript" src="com.acme.gwt.Module.nocache.js"></script>
<script language="javascript" src="com.acme.gwt.Module2.nocache.js"></script>

您还需要将web服务器配置为向.nocache的请求添加头。防止客户端浏览器缓存的文件。如果缓存了这些文件,客户端将不容易看到应用程序的新版本。web服务器可移植的方法是使用servlet过滤器:

public class CacheHeaderFilter implements Filter {

    public void doFilter(ServletRequest req, ServletResponse res,
            FilterChain filterChain) throws IOException, ServletException {
        String uri = ((HttpServletRequest)req).getRequestURI();
        if (uri.contains(".cache.")) {
            ((HttpServletResponse)res).setDateHeader("Expires",
                System.currentTimeMillis() + 31536000000L);
        } else if (uri.contains(".nocache.")) {
            ((HttpServletResponse)res).setHeader("Cache-Control", "no-cache");
        }
        filterChain.doFilter(req, res);
    }
...
}

<filter>
    <filter-name>cacheHeaderFilter</filter-name>
    <filter-class>com.acme.gwt.server.CacheHeaderFilter</filter-class>
</filter>
