【JAVA基础】springMVC 整合freemarker（maven）

当今最流行的java模板引擎，莫过于freemarker和velocity。这里我弄个springMVC整合freemark的例子分享给大家。

基本的就不说了，直接入正题。

第一步：pom文件的依赖包

  <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>3.2.4.RELEASE</version>
    </dependency>
    
    <dependency>
	        <groupId>org.freemarker</groupId>
		<artifactId>freemarker</artifactId>
		<version>2.3.20</version>
	</dependency>
	
	<dependency>
	    <groupId>org.springframework</groupId>
	    <artifactId>spring-context-support</artifactId>
	    <version>3.2.4.RELEASE</version>
	</dependency>

第二步：web.xml配置

  <servlet>
	        <servlet-name>demo</servlet-name>
	        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
	        <load-on-startup>1</load-on-startup>
	</servlet>
	
	<servlet-mapping>
	        <servlet-name>demo</servlet-name>
	        <url-pattern>*.html</url-pattern>
	</servlet-mapping>

第三步：在WEN-INF下面 再建一个demo-servlet.xml

<?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:p="http://www.springframework.org/schema/p" 
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context 
        http://www.springframework.org/schema/context/spring-context.xsd">


    <context:component-scan base-package="com"/>


    <!-- ... -->

</beans>

第四步：在java/main/resource目录下新增freemarker.properties配置文件

#u8BBEu7F6Eu6807u7B7Eu7C7Bu578BuFF1Asquare_bracket:[]     auto_detect:[]<>
tag_syntax=auto_detect
#u6A21u7248u7F13u5B58u65F6u95F4uFF0Cu5355u4F4DuFF1Au79D2
template_update_delay=0
default_encoding=UTF-8
output_encoding=UTF-8
locale=zh_CN
#u8BBEu7F6Eu6570u5B57u683Cu5F0F uFF0Cu9632u6B62u51FAu73B0 000.00
number_format=#
#u53D8u91CFu4E3Au7A7Au65F6uFF0Cu4E0Du4F1Au62A5u9519
classic_compatible=true
#auto_import="/WEB-INF/templates/index.ftl" as do

第五步：在demo-servlet.xml中增加freemarker视图配置

 <!-- 设置freeMarker的配置文件路径 -->
		<bean id="freemarkerConfiguration" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
		    <property name="location" value="classpath:freemarker.properties"/>
		</bean>
		
		<!-- 配置freeMarker的模板路径 -->
		<bean class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
			<property name="freemarkerSettings" ref="freemarkerConfiguration"/>
		    <property name="templateLoaderPath">
		        <value>/WEB-INF/ftl/</value>
		    </property>
		</bean>
		
		<!-- 配置freeMarker视图解析器 -->
		<bean id="viewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
		    <property name="viewClass" value="org.springframework.web.servlet.view.freemarker.FreeMarkerView"/>
		    <property name="contentType" value="text/html; charset=utf-8"/>
		    <property name="cache" value="true"/>
		</bean>

第六部：controller

package com.testFreeMarker.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 com.testFreeMarker.model.User;

@Controller
public class FreemarkerController {
	
	@RequestMapping("/hi")
	public String sayHello(ModelMap map){
        System.out.println("哈哈哈");
        map.put("name", "测试一下这个freeMarker");

        return "/hi.ftl";
	}
	
	@RequestMapping("/user")
    public String helloUser(ModelMap modelMap) {
		User user1=new User(1, "罗宾", "123456");
		User user2=new User(2, "老施", "123456");
		User user3=new User(3, "老大", "123456");
		User user4=new User(4, "老板", "123456");
		List<User> list=new ArrayList<User>();
		list.add(user1);
		list.add(user2);
		list.add(user3);
		list.add(user4);
        modelMap.addAttribute("userDo", list) ;
        return "/userList.ftl";
    }
}

User

package com.testFreeMarker.model;

public class User {
	private int id;
	private String username;
	private String password;
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
	public User(int id, String username, String password) {
		super();
		this.id = id;
		this.username = username;
		this.password = password;
	}

}

hi.ftl

<html>
<body>
    <h1>say hello ${name}</h1><br/>
    ${(1 != 1)?string("yes", "no")}
</body>
</html>

userList.ftl

    </table></td>

  </tr>
  <tr>

    <td width="500" height="200"> </td>
    <td width="500" height="200"> </td>
  </tr>
</table>
</body>
</html>

最后看一下目录结构：
