由于项目需要，需要使用FreeMarker ，今天正好研究就写了一个简单的小例子
首先配置web.xml,
<servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.from</url-pattern> </servlet-mapping>
然后配置applicationContext.xml
<bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"> <property name="templateLoaderPath" value="/WEB-INF/pages/" /> <property name="freemarkerSettings"> <props> <prop key="defaultEncoding">GBK</prop> </props> </property> </bean> <bean id="freeMarkerViewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver"> <property name="cache" value="true" /> <property name="prefix" value="" /> <property name="suffix" value=".ftl" /> <property name="order" value="1" /> <property name="contentType"> <value>text/html;charset=GBK</value> </property> </bean>
接着需要写一个简单的实体类（省略），以及一个Controller
@Controller
@RequestMapping("/demo")
public class TestController {
@RequestMapping("/test.from")
public String test(Model model){
List<Users> list = new ArrayList<Users>();
Users user1 = new Users();
user1.setId(1);
user1.setUserName("任飘渺");
user1.setGender("男");
user1.setSal(5000.0);
Users user2 = new Users();
user2.setId(2);
user2.setUserName("文荒");
user2.setGender("男");
user2.setSal(5000.0);
Users user3 = new Users();
user3.setId(3);
user3.setUserName("任风歌");
user3.setGender("男");
user3.setSal(5000.0);
Users user4 = new Users();
user4.setId(4);
user4.setUserName("陨落");
user4.setGender("男");
//user4.setSal(5000.0); 测试空值处理
list.add(user1);
list.add(user2);
list.add(user3);
list.add(user4);
model.addAttribute("username", "slayers")
.addAttribute("pwd", "123456").addAttribute("userlist",list);
return "user";
}之后的就需要我们写一个ftl文件 user.ftl
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK" />
</head>
<body>
welcome ${username}! Your PWD is ${pwd}<br/>
<div>
<table>
<#list userlist as user>
<tr><td>编号：</td><td><input type="text" value="${(user.id)!}" /></td></tr>
<tr><td>姓名：</td><td><input type="text" value="${(user.userName)!}" /></td></tr>
<tr><td>性别：</td><td><input type="text" value="${(user.gender)!}" /></td></tr>
<tr><td>薪水：</td><td><input type="text" value="${(user.sal)!}" /></td></tr>
</#list>
</table>
</div>
</body>
</html>这样一个简单的实例就完成了 上面的ftl中 对空值 做了${(xxx)!}这种方式的处理以免又是报错
