配置tomcat，禁用缓存

DisableCacheFilter.java

import javax.servlet.*;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Date;

public class DisableCacheFilter implements Filter {

	public void doFilter(ServletRequest request, ServletResponse response,
	                     FilterChain chain) throws IOException, ServletException {

		HttpServletResponse resp = (HttpServletResponse) response;
		resp.setHeader("Cache-Control", "no-store, no-cache, must-revalidate, max-age=0");
		resp.setHeader("Pragma", "no-cache");

		chain.doFilter(request, response);
	}

	public void destroy() {

	}

	public void init(FilterConfig arg0) throws ServletException {

	}

}

web.xml

<filter>
	<filter-name>DisableCacheFilter</filter-name>
	<filter-class>DisableCacheFilter</filter-class>
</filter>

<filter-mapping>
	<filter-name>DisableCacheFilter</filter-name>
	<url-pattern>/*</url-pattern>
</filter-mapping>

DisableCacheFilter.java编译成class后放到tomcat/lib目录
