Java 对servlet映射感到困惑

我在web.xml中将servlet配置为默认servlet

<servlet-mapping>
    <servlet-name>myServlet</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

java

package com.test;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class MyServlet extends HttpServlet {

    private static Logger LOG = LoggerFactory.getLogger(MyServlet.class);

    @Override
    protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        super.service(req, resp);
        LOG.info("Served");
    }
}

如果使用

/

，则不会覆盖容器的默认servlet和JSP servlet。如果希望所有请求都由MyServlet处理，则应使用

/*

您也可以共享Servlet类中的代码吗？请同时共享您的web.xml

package com.test;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;

public class MyServlet extends HttpServlet {

    private static Logger LOG = LoggerFactory.getLogger(MyServlet.class);

    @Override
    protected void service(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        super.service(req, resp);
        LOG.info("Served");
    }
}
