springBoot去除了spring复杂的配置，我们终于可以安心的写业务代码了。话不多说，直接开干。这里使用thymeleaf作为视图。

1.实体类

public class Person {
    private String name;
    private Integer age;
    public Person(){
        super();
    }
    public Person(String name,Integer age){
        super();
        this.name=name;
        this.age=age;
    }

    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;
    }
}

2.控制器：

@Controller
@SpringBootApplication
public class FirstSpringBootApplication {

    @RequestMapping("/")
    public String index(Model model) {
        Person single = new Person("aa", 11);
        List<Person> people = new ArrayList<>();
        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(FirstSpringBootApplication.class, args);
    }
}

3.视图：（需按约定放在templates目录下）

<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"/>
    <title>Title</title>
</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>
                    <sapn th:text="${person.age}"></sapn>
                    <button class="btn" th:οnclick="'getName(\''+${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}"></script>
<script th:inline="javascript">
    var single = [[${singlePerson}]];
    console.log(single.name + "/" + single.age);
    function getName(name) {
        console.log(name);
    }
</script>
</body>
</html>
