使Struts2与Servlet并存解决办法
解决办法:
在Struts2过滤器前增加一个过滤器，使用过滤器转发到servlet上
web.xml配置:
01
<filter>
02
<filter-name>JSONRPCServlet</filter-name>
03
<filter-class>filters.ReDispatcherFilter</filter-class>
04
<init-param>
05
<param-name>includeServlets</param-name>
06
<param-value>JRPC</param-value>
07
<!--注:JRPC为下文配置的Servlet JSONRPCServlet过滤的请求配置 -->
08
</init-param>
09
</filter>
10
<filter-mapping>
11
<filter-name>JSONRPCServlet</filter-name>
12
<url-pattern>/*</url-pattern>
13
</filter-mapping>
14
15
16
<filter>
17
<filter-name>struts2</filter-name>
18
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
19
</filter>
20
<filter-mapping>
21
<filter-name>struts2</filter-name>
22
<url-pattern>*.action</url-pattern>
23
</filter-mapping>
24
25
<filter-mapping>
26
<filter-name>struts2</filter-name>
27
<url-pattern>/*</url-pattern>
28
</filter-mapping>
29
30
<!--注：这里同样需要Servlet配置，Filter会转到该Servlet上-->
31
<servlet>
32
<servlet-name>JSONRPCServlet</servlet-name>
33
<servlet-class>
34
jcore.jsonrpc.servlet.JSONRPCServlet
35
</servlet-class>
36
<load-on-startup>2</load-on-startup>
37
</servlet>
38
<servlet-mapping>
39
<servlet-name>JSONRPCServlet</servlet-name>
40
<url-pattern>/JRPC</url-pattern>
41
</servlet-mapping>
过滤器的实现类:

public class ReDispatcherFilter implements Filter {

}
22
23
public void doFilter(ServletRequest req, ServletResponse resp,
24
FilterChain chain) throws IOException, ServletException {
25
26
HttpServletRequest request = (HttpServletRequest) req;
27
String target = request.getRequestURI();
28
target = target.lastIndexOf("?") > 0 ? target.substring(target
29
.lastIndexOf("/") + 1, target.lastIndexOf("?")
30

31
.lastIndexOf("/") + 1);
32
33
//System.out.println(target);
34
if (this.includes.contains(target)) {
35
RequestDispatcher rdsp = request.getRequestDispatcher(target);
36
37
//System.out.println("go..............." + rdsp);
38
rdsp.forward(req, resp);
39
} else
40
chain.doFilter(req, resp);
41
}
42
43
private ArrayList<String> includes = new ArrayList<String>();
44
45
public void init(FilterConfig config) throws ServletException {
46
47
this.includes.addAll(Arrays.asList(config.getInitParameter(
48
"includeServlets").split(",")));

}

}
