eclipse springmvc+Thymeleaf

修改pom.xml引入Thymeleaf相关包：

<project xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

    <build>

修改springmvc-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:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:util="http://www.springframework.org/schema/util"
    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/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd              
            http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd">

    <!-- 激活@Controller模式 -->
    <mvc:annotation-driven />
    <!-- 对包中的所有类进行扫描，以完成Bean创建和自动依赖注入的功能 需要更改 -->
    <context:component-scan
        base-package="org.xuan.springmvc.controller" />

    <mvc:resources location="/static/" mapping="/static/**" />

    <!-- 模板解析器 -->
    <bean id="templateResolver"
        class="org.thymeleaf.templateresolver.ServletContextTemplateResolver">
        <property name="prefix" value="/WEB-INF/templates/" />
        <property name="suffix" value=".html" />
        <property name="templateMode" value="HTML5" />
        <property name="cacheable" value="false" />
        <property name="characterEncoding" value="UTF-8" />
    </bean>

    <bean id="templateEngine"
        class="org.thymeleaf.spring4.SpringTemplateEngine">
        <property name="templateResolver" ref="templateResolver" />
    </bean>

    <bean class="org.thymeleaf.spring4.view.ThymeleafViewResolver">
        <property name="templateEngine" ref="templateEngine" />
        <property name="characterEncoding" value="UTF-8" />
    </bean>

</beans>

在WEB-INF下面新建templates目录，在templates下面新建hello.html：

<html xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8" />
<script type="text/javascript" src="static/js/jquery-1.10.2.min.js"
    th:src="@{/static/js/jquery-1.10.2.min.js}"></script>

<script th:inline="javascript">
  $(function(){
   var _ctx = [[${application.ctx}]];
    alert("Project ContextPath:"+_ctx);
    alert("路径:"+$("#ctx").val());
  });
</script>
<title>Spring MVC + Thymeleaf Example</title>
</head>
<body>
    <!-- Project ContextPath -->
    <input type="hidden" id="ctx" th:value="${application.ctx}" /> Hello,
    <span th:text="${name}" />!
    <br /> Hello,
    <span th:text="${query}" />!
    <br /> Hello,
    <span th:text="${submit}" />!
    <br />
    <a th:href="@{/query?name=a_href}"> query</a>
    <br />
    <form th:action="@{/submit}">
        <input type="text" name="name" /><input type="text" name="age" />
        <button type="submit">submit</button>
    </form>

</body>
</html>

修改MainController.java：

package org.xuan.springmvc.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class MainController {
    @RequestMapping(value = "/{name}", method = RequestMethod.GET)
    public String getMovie(@PathVariable String name, ModelMap model) {
        model.addAttribute("name", name);
        model.addAttribute("query", "");
        model.addAttribute("submit", "");
        return "hello";
    }

    @RequestMapping(value = "/query", method = RequestMethod.GET)
    public String query(@RequestParam("name") String name, ModelMap model) {
        model.addAttribute("name", "");
        model.addAttribute("query", name);
        model.addAttribute("submit", "");
        return "hello";
    }

    @RequestMapping(value = "/submit", method = RequestMethod.GET)
    public String submit(@RequestParam("name") String name, @RequestParam("age") String age, ModelMap model) {
        model.addAttribute("name", "");
        model.addAttribute("query", "");
        model.addAttribute("submit", name + age);
        return "hello";
    }
}

整个项目的目录结构如下:
