src>main>建立java>建立package(my.web.Controller)>建立MainController.java

【MainController.java】
package my.web.Controller;

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

@Controller
public class MainController {
  @RequestMapping("hello")
  public String to_hello(String user, Model model) {
        model.addAttribute("user", user);
  return "hello";
  }
}
測試用的hello.jsp
放置於WEB-INF/page/目錄下
<%@ page contentType = "text/html;charset=UTF-8" %>
<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>Hello page</title>
</head>
<body>
    <div>
        <h1>Hello ${user}!!</h1>
    </div>
</body>
</html>
其他：
在專案上右鍵>MAVEN>update project
如果無法升級至Dynamic Web Module 2.5
在專案上右鍵>properties>project facets把Dynamic Web Module 取消勾選，再update一次


將eclipse的window>preference>General>Workspace>Text file encoding改為UTF-8




加入tiles
【POM.xml】

</dependencies>
【SpringConfig.xml】

更改 viewResolver.order：
<!-- 因為使用了其他的ViewResolver(ex:tiles)，因此必須設定解析順序 -->
<property name="order" value="#{tilesViewResolver.order+1}" />

加入：
<!-- Tiles View -->
<bean id="tilesViewResolver"
class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="viewClass"
        value="org.springframework.web.servlet.view.tiles3.TilesView" />
<property name="order" value="1" />
</bean>
<!-- 加載tiles配置文件 -->
<bean id="tilesConfigurer"
class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
<property name="definitions">
<list> <!-- 設定檔路徑 -->
<value>/WEB-INF/config/defaultTemplate.xml</value>
<value>/WEB-INF/config/tiles-definitions.xml</value>
</list>
  </property>
<!-- 定義preparerFactory的種類(有2種: SimpleSpring & SpringBean) -->
<property name="preparerFactoryClass"
value="org.springframework.web.servlet.view.tiles3.SimpleSpringPreparerFactory" />
</bean>
