jsp过滤器执行顺序

在一个大型项目中往往有多个servlet过滤器，但是这些servlet过滤器的执行顺序是怎样的呢？ 项目中关于SSH2中OpenSessionInViewFilter的学习研究，测试Filter的先后顺序！！
请看一下例子： 
创建两个简单的servlet文件 
package filter; 
import java.io.IOException; 
import javax.servlet.Filter; 
import javax.servlet.FilterChain; 
import javax.servlet.FilterConfig; 
import javax.servlet.ServletException; 
import javax.servlet.ServletRequest; 
import javax.servlet.ServletResponse; 
public class Filter1 implements Filter { 
public void destroy() { 
} 
public void init(FilterConfig config) throws ServletException { 
} 
public void doFilter(ServletRequest request, ServletResponse response, 
  FilterChain chain) throws IOException, ServletException { 
 try { 
  System.out.println("filter1"); 
  chain.doFilter(request, response); 
  System.out.println("filter1  go back"); 
 } catch (Exception e) { 
  e.printStackTrace(); 
 } 
} 
}
package filter; 
import java.io.IOException; 
import javax.servlet.Filter; 
import javax.servlet.FilterChain; 
import javax.servlet.FilterConfig; 
import javax.servlet.ServletException; 
import javax.servlet.ServletRequest; 
import javax.servlet.ServletResponse; 
public class Filter2 implements Filter { 
public void destroy() { 
} 
public void init(FilterConfig config) throws ServletException { 
} 
public void doFilter(ServletRequest request, ServletResponse response, 
  FilterChain chain) throws IOException, ServletException { 
 try { 
  System.out.println("filter2"); 
  chain.doFilter(request, response); 
  System.out.println("filter2   go back"); 
 } catch (Exception e) { 
  e.printStackTrace();
