Spring Boot JSP ViewResolver 구성

JSP 파일 위치를 해결하려면 두 가지 방법을 사용할 수 있습니다.

1) application.properties에 항목 추가

#http port
server.port=7070

spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp

2) JSP 페이지를 제공하도록 InternalResourceViewResolver 구성

package com.bluexmas.config;
 
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ViewResolverRegistry;

import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;
 
@Configuration
@EnableWebMvc
@ComponentScan
public class MvcConfiguration extends WebMvcConfigurerAdapter
{
  @Override
  public void configureViewResolvers(ViewResolverRegistry registry) {
    InternalResourceViewResolver resolver = new InternalResourceViewResolver();
    resolver.setPrefix("/WEB-INF/view/");
    resolver.setSuffix(".jsp");
    resolver.setViewClass(JstlView.class);
    registry.viewResolver(resolver);
  }
}

Controller 소스

package com.bluexmas.controller;

import java.util.ArrayList;
import java.util.List;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class SampleController {
	
	/*
	 * 스프링부트에서의 jsp 호출 테스트
	 */
	@RequestMapping("/jspSample")
	public String jspSample(ModelMap modelMap) throws Exception {
		modelMap.put("name", "홍길동");

		List jspSample = new ArrayList();
		jspSample.add("국어 : 100점");
		jspSample.add("수학 : 90점");
		jspSample.add("영어 : 75점");

		modelMap.put("list", jspSample);
		
		return "jspSample";
	}
}

View(JSP) - src\main\webapp\WEB-INF\jsp\jspSample.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
 
<html>
<head>
<meta charset="UTF-8">
    <title>JSP Sample Page</title>
</head>
    <body>
 
       <div>[${name}]님의 시험성적입니다.</div>
 
        <c:forEach var="item" items="${list}">
         ${item} <br />
        </c:forEach>
 
    </body>
</html>
