上一篇 提到用组件注册servlet 可能后期修改注册名或路径的时候如果servlet过多可能不够便利

本节就跟大家 说一下另一种方法：用特定的方法在servlet外部绑定

首先按照上一篇创建一个servlet 代码如下

package com.wqc.serverlet;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class MyServlet2 extends HttpServlet {

	@Override
	protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
		// TODO Auto-generated method stub
		super.doGet(req, resp);
		System.out.println("Myservlet   2");
	}
}

然后在入口处调用绑定函数

package com.wqc;

import javax.servlet.annotation.WebServlet;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;

import com.wqc.serverlet.MyServlet2;

/**
 * 启动
 * @author Administrator
 *
 */
@SpringBootApplication
public class App {

	public static void main(String[] args) {
		SpringApplication.run(App.class, args);
	}
	
	@Bean
	public ServletRegistrationBean getServletRegistrationBean() {
		ServletRegistrationBean bean = new ServletRegistrationBean(new MyServlet2());
		bean.addUrlMappings("/myser2");
		return bean;
		
	}
}

这样就实现了然后就可以按照上一篇的方法访问看成果了
