【附源码】搭建spring mvc +freemarker

【源码下载地址：http://pan.baidu.com/s/1nuSKV6h】

准备jar包：
commons-logging-1.2.jar
freemarker-2.3.19.jar
spring-3.2.0.M1（spring3.2的所有jar，包含60个jar）

开发环境:

JDK 1.8

MyEclipse 10

Tomcat 6

1、用MyEclipse创建Web
Porject。Porject名称：TestSpringMvcPrj。
2、在WEB-INF/web.xml里面添加一下代码：

Xml代码



<servlet>

<servlet-name>springmvc</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<load-on-startup>2</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>springmvc</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

注意是添加在web-app区间内。
添加后效果：
<?xmlversion="1.0" encoding="UTF-8"?>
<web-appversion="3.0"

xmlns="http://java.sun.com/xml/ns/javaee"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<display-name></display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>2</load-on-startup>

</servlet>

<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>

</servlet-mapping>
</web-app>

springmvc 主要通过DispatcherServlet做分发。上面的servlet名字叫springmvc所以在WEB-INF下面新建一个springmvc-servlet.xml文件

3、springmvc-servlet.xml配置

Xml代码



<?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:context="http://www.springframework.org/schema/context"

xmlns:aop="http://www.springframework.org/schema/aop" xmlns:p="http://www.springframework.org/schema/p"

xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/beans/spring-beans-3.0.xsd

http://www.springframework.org/schema/context

http://www.springframework.org/schema/context/spring-context-3.0.xsd

http://www.springframework.org/schema/tx

http://www.springframework.org/schema/tx/spring-tx-3.0.xsd

http://www.springframework.org/schema/jdbc

http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd">

<!--注解说明 -->

<context:annotation-config />

<!-- 把标记了@Controller注解的类转换为bean -->

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

<!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 请求映射 -->

<bean

class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />

<!-- freemarker的配置 -->

<bean id="freemarkerConfigurer"

class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">

<!-- 配置模板路径 -->

<property name="templateLoaderPath" value="/WEB-INF/view/" />

<property name="defaultEncoding" value="GBK" />

<property name="freemarkerSettings">

<props>

<!--更新模板文件间隔10毫秒
-->

<prop key="template_update_delay">10</prop>

<prop key="locale">zh_CN</prop>

<prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>

<prop key="date_format">yyyy-MM-dd</prop>

<prop key="number_format">#.##</prop>

</props>

</property>

</bean>

<!-- FreeMarker视图解析 如返回userinfo。。在这里配置后缀名ftl和视图解析器。。 -->

<bean id="viewResolver"

class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">

<property name="viewClass"

value="org.springframework.web.servlet.view.freemarker.FreeMarkerView" />

<property name="suffix" value=".ftl" />

<property name="contentType" value="text/html;charset=GBK" />

<property name="exposeRequestAttributes" value="true" />

<property name="exposeSessionAttributes" value="true" />

<property name="exposeSpringMacroHelpers" value="true" />

</bean>

<bean id="messageSource"

class="org.springframework.context.support.ResourceBundleMessageSource"

p:basename="i18n/messages" />

</beans>

4、写控制层代码：
4.1MessageController.Java

Java代码



package com.lantii.action;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;

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

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

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

@Controller

@RequestMapping("/message")

// url映射的名称

public class MessageController {

@RequestMapping(value = "/{msg}", method = RequestMethod.GET)

public String showMessage(@PathVariable String msg,

HttpServletRequest request, HttpServletResponse response) {

// TODO 处理请求

request.setAttribute("message", msg); // 设置返回消息

return "message"; // 设置返回页面，这里对应 /WEB-INF/view 目录下的 message.ftl 文件

}

@RequestMapping(value = "/add")

public String addMessage(HttpServletRequest request, HttpServletResponse response) {

request.setAttribute("message", "message is added");

return "message";

}

}

4.2UserController.java

Java代码



package com.lantii.action;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Controller;

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

import com.lantii.business.user.User;

@Controller

@RequestMapping("/user")

public class UserController {

@RequestMapping(value = "/login")

public String test(HttpServletRequest request,

HttpServletResponse response, User userinfo) { // 非常方便可以直接在方法里面放入对象

if (userinfo.getUsername().equals("lantii")

&& userinfo.getPassword().equals("ok")) {

request.setAttribute("userinfo", userinfo);

return "users/loginok"; // 判断，将跳转不同的页面

} else {

return "users/loginerr"; // 判断，将跳转不同的页面

}

}

}

4.3User.java

Java代码



package com.lantii.business.user;

public class User {

private String username;

private String password;

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;

}

}

5、编写模板
5.1返回页message.ftl



<html>

<body>

<p>This is my message:<br> ${message}</p>

</body>

</html>

5.2users下loginok.ftl



<html>

<body>

hi, <b>${userinfo.username}</b>

</body>

</html>

5.3 users下loginerr.ftl
<html>
<body>

error<br>

</body>
</html>

6、前台调用的测试jsp

Java代码



<%@ page language="java" contentType="text/html; charset=GBK"

pageEncoding="GBK"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=GBK">

<title>主页</title>

</head>

<body>

<form METHOD=POST ACTION="user/login">

用户名：<input TYPE="text" NAME="username" value="lantii"><br>

密 码：<input TYPE="text" NAME="password" value="ok"><br> <input

TYPE="submit">

</form>

<br>

<a href="message/add" target="_blank">add</a>

<br>

<a href="message/哈哈哈" target="_blank">see：哈哈哈</a>

</body>

</html>

project目录结构：



7、接下来发布project
