spring + freemarker

테스트를 위해 로컬에 환경을 구현해보았다.

freemarker 라이브러리 다운 페이지

1. web.xml

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

<display-name>Sample_Spring3.0</display-name>

<!-- Spring Dispatcher Servlet //-->  

<servlet>

<servlet-name>spring</servlet-name>

</servlet>

<servlet-mapping>

<url-pattern>*.free</url-pattern>

<init-param>

<param-name>encoding</param-name>

<param-value>UTF-8</param-value>

</init-param>

</filter>

    <filter-mapping>

        <filter-name>encodingFilter</filter-name>

        <url-pattern>*</url-pattern>

    </filter-mapping>

<!-- // Encoding -->

   

</web-app>

오랜만에 하니 헷갈리는 부분이 있었다. servlet에서 url-pattern을 *로 설정하는 실수를 했더니 모든게 서블릿으로 동작하고 view와 연결이 안되고 404 에러가 나온다. 하지만 controller는 타고 넘어간다. 주의해야겠다.

2. spring-servlet.xml

3. TestController 작성 : /src/rsa/controller/TestController.java

package rsa.controller;

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.servlet.ModelAndView;

@Controller

public class TestController {

//http://localhost.home.com:8080/rsa/test.jsp

@RequestMapping("/rsa/test")

public ModelAndView test(){

String message = "Hello World 한글";

System.out.println("/rsa/test --> 실행됨");

//ModelAndView mnv = new ModelAndView();

//mnv.setViewName("/rsa/test");

//mnv.addObject("message", message);

//return mnv;

return new ModelAndView("/rsa/test.ftl", "message", message);

}

}

4. view 작성 : /WebContent/WEB-INF/freemarker/rsa/test.ftl

<#ftl encoding="utf-8"/>

<html>

<head>

</head>

<h2>Spring3 Test Page</h2>

<body>

    Controller return value : ${message}

</body>

</html>

http://localhost.home.com:8080/rsa/test.free 으로 동작을 확인했다.

참고로 2가지 작업이 필요한데

본인은 로컬에서 돌릴 때, hosts 파일에 localhost.home.com을 도메인으로 만들고 test한다.

톰켓 설정은 실행한 프로젝트를 root( / )로 설정한다.

freemarker를 정식으로 공부해보고 싶지만 많이 사용하지 않는듯해서 API문서만 보고있다. 개인적으로는 jsp보다 좋은듯하다.
