转：springboot servlet使用配置
小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

在spring boot中添加自己的Servlet有兩種方法，代碼注冊Servlet和注解自動注冊（Filter和Listener也是如此）。
【1】手動注冊servlet
一、代碼注冊通過ServletRegistrationBean 獲得控制。? 也可以通過實(shí)現(xiàn) ServletContextInitializer 接口直接注冊。
?
package com.kerry.servlet;import java.io.IOException; import java.io.PrintWriter;import javax.servlet.ServletException; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;public class MyServlet1 extends HttpServlet{private static final long serialVersionUID = 8031133938454140403L;@Overrideprotected void service(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {resp.setContentType("text/html"); PrintWriter out = resp.getWriter(); out.println("<html>"); out.println("<head>"); out.println("<title>Hello World</title>"); out.println("</head>"); out.println("<body>"); out.println("<h1>welcome this is my servlet1!!!</h1>"); out.println("</body>"); out.println("</html>"); }} package com.kerry.configure;import org.springframework.boot.web.servlet.ServletRegistrationBean; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration;import com.kerry.servlet.MyServlet; import com.kerry.servlet.MyServlet1;@Configuration public class ServletConfigure {/*** 代碼注冊servlet(不需要@ServletComponentScan注解)* @return*/@Beanpublic ServletRegistrationBean servletRegistrationBean() {return new ServletRegistrationBean(new MyServlet1(), "/servlet/myServlet1");// ServletName默認(rèn)值為首字母小寫，即myServlet1}/*** 多個servlet就注冊多個bean* @return*/@Beanpublic ServletRegistrationBean servletRegistrationBean1() {return new ServletRegistrationBean(new MyServlet(), "/servlet/myServlet");// ServletName默認(rèn)值為首字母小寫，即myServlet}}?
【2】使用WebServlet 注解
1 Application上加上@ServletComponentScan注解
package com.kerry;import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.web.servlet.ServletComponentScan;@SpringBootApplication @MapperScan("com.kerry.mapper") @ServletComponentScan public class Application {public static void main(String[] args) {SpringApplication.run(Application.class, args);} }2 servlet上加上@WebServlet注解
package com.kerry.servlet;import java.io.IOException; import java.io.PrintWriter;import javax.servlet.ServletException; import javax.servlet.annotation.WebServlet; import javax.servlet.http.HttpServlet; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse;/*** 注解使用servlet 需要在Application上加入 @ServletComponentScan* @author Administrator**/ @WebServlet(name="myServlet",urlPatterns="/servlet/myServlet") public class MyServlet extends HttpServlet{private static final long serialVersionUID = 8031133938454140403L;@Overrideprotected void service(HttpServletRequest req, HttpServletResponse resp)throws ServletException, IOException {resp.setContentType("text/html"); PrintWriter out = resp.getWriter(); out.println("<html>"); out.println("<head>"); out.println("<title>Hello World</title>"); out.println("</head>"); out.println("<body>"); out.println("<h1>welcome this is my servlet!!!</h1>"); out.println("</body>"); out.println("</html>"); }}3） 附上項(xiàng)目結(jié)構(gòu)
