Spring - Web MVC + Tomcat

• build.gradle 추가 설정

//srping webmvc
implementation 'org.springframework:spring-webmvc:5.3.19'

• webapp - resources 패키지, WEB-INF - views 패키지 생성, servlet-context.xml 생성

• controller - SampleController 클래스 생성

• servlet-context 설정(xsi:schemaLocation 주소 중요)

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

    <mvc:resources mapping="/resources/**" location="/resources/"/>

    <context:component-scan base-package="org.board.controller"/>

    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"></property>
        <property name="suffix" value=".jsp"></property>
    </bean>

</beans>

• web.xml 설정

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </filter-mapping>

</web-app>

• controller - SampleController

package org.board.controller;

import lombok.extern.log4j.Log4j2;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;

@Controller
@Log4j2
public class SampleController {

    @GetMapping("/hello")
    public void helloTest(){
        log.info("hello");
    }

}

• views - hello.jsp 생성
  

• Tomcat - edit

• Deployment 설정

• server 설정

• localhost:8080/hello 호출

• 결과
