SpringBoot-Thymeleaf模板

### 一、需求 ###

> 利用SpringBoot和Thymeleaf进行集成

### 二、演示 ###

#### 1、创建一个SpringBoot项目 ####

pom文件

    				<enabled>false</enabled>
    			</snapshots>
    		</pluginRepository>
    	</pluginRepositories>
    
    </project>

#### 2、新建Person类 ####

此类用来在模板页面展示数据，其中包含了name属性和age属性。

package com.eleven.pojo;
    
    public class Person { 
    	private String name;
    	private Integer age;
    	
    	
    	public Person(String name, Integer age) { 
    		super();
    		this.name = name;
    		this.age = age;
    	}
    	public Person() { 
    		super();
    	}
    	public String getName() { 
    		return name;
    	}
    	public void setName(String name) { 
    		this.name = name;
    	}
    	public Integer getAge() { 
    		return age;
    	}
    	public void setAge(Integer age) { 
    		this.age = age;
    	}
    	
    	
    
    }

#### 3、添加静态资源 ####

本示例中，主要用到了bootstrap和jquery

#### 4、演示页面index.html ####

根据默认原则，页面应该放置在src/main/resources/templates下

<!DOCTYPE html>
    <html xmlns:th="http://www.thymeleaf.org">	
    <head>
     	 <meta content="text/html;charset=UTF-8"/>
      	 <meta http-equiv="X-UA-Compatible" content="IE=edge"/>
         <meta name="viewport" content="width=device-width, initial-scale=1"/>
    <link th:href="@{bootstrap/css/bootstrap.min.css}" rel="stylesheet"/>	
    <link th:href="@{bootstrap/css/bootstrap-theme.min.css}" rel="stylesheet"/>
    </head>
    <body>
    	<div class="panel panel-primary">
    		<div class="panel-heading">
    			<h3 class="panel-title">访问model</h3>
    		</div>
    		<div class="panel-body">
    			<span th:text="${singlePerson.name}"></span>	
    		</div>
    	</div>
    	
    	<div th:if="${not #lists.isEmpty(people)}">	
    		<div class="panel panel-primary">
    			<div class="panel-heading">
    				<h3 class="panel-title">列表</h3>
    			</div>
    			<div class="panel-body">
    				<ul class="list-group">
    					<li class="list-group-item" th:each="person:${people}">
    						<span th:text="${person.name}"></span>
    						<span th:text="${person.age}"></span>
    						<button class="btn" th:onclick="'getName(\'' + ${person.name} + '\');'">获得名字</button>
    					</li>
    				</ul>
    			</div>
    		</div>
    	</div>
    	
    <script th:src="@{jquery-1.10.2.min.js}" type="text/javascript"></script>
    <script th:src="@{bootstrap/js/bootstrap.min.js}" type="text/javascript"></script>
    	
    	<script th:inline="javascript"> /* 通过th:inline="javascript"添加到script标签中，这样JavaScript代码就可以访问model中的属性 */ var single = [[${ singlePerson}]]; /* 通过[[${}]]格式获得实际的值 */ console.log(single.name+"/"+single.age) function getName(name){ console.log(name); } </script>
    </body>
    </html>

#### 5、入口类添加数据 ####

package com.eleven;
    
    import java.util.ArrayList;
    import java.util.List;
    
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.RequestMapping;
    
    import com.eleven.pojo.Person;
    
    @Controller
    @SpringBootApplication
    public class Application { 
    	
    	@RequestMapping("/")
    	public String index(Model model) { 
    		Person single = new Person("aa",11);
    		List<Person> people = new ArrayList<Person>();
    		Person p1 = new Person("xx",11);
    		Person p2 = new Person("yy",22);
    		Person p3 = new Person("zz",33);
    		people.add(p1);
    		people.add(p2);
    		people.add(p3);
    		
    		model.addAttribute("singlePerson", single);
    		model.addAttribute("people", people);
    		return "index";
    	}
    	
    	public static void main(String[] args) { 
    		SpringApplication.run(Application.class, args);
    	}
    
    }

#### 6、运行访问 ####

输入地址localhost:8080，出现下图页面，右键检查（F12），找到console，在页面点击获得名字即可看到信息在控制台输出。
