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();
