一、Spring Boot简介
主要特性:
- Spring Boot Starter:它将常用的依赖分组进行整合,将其合并到一个依赖中,这样就可以一次性添加到项目到Maven构建中;
- 自动配置:Spring Boot的自动配置特性利用了Spring4对条件化配置对支持,合理地推测应用所需要的bean并自动配置它们;
- 命令行接口(CLI)
- Actuator
自动配置
Spring Boot的Starter减少了构建中依赖列表的长度,而Spring Boot的自动配置功能则削减了Spring配置的数量。它在实现时,会考虑应用中的其他因素并推断你需要的Spring配置。
二、使用Spring Boot构建应用
我们的应用是一个简单的联系人列表。(Contacts)
Maven构建

Maven构架有一个parent醒目,让项目的Maven构建基于spring-boot-starter-parent,这样的话,受益于Maven的依赖管理功能,对于项目中的很多依赖,就没有必要明确声明版本号了,因为版本号会从parent中继承得到。
项目的标准结构:
处理请求
使用Spring MVC开发应用的WEB层,而Spring Boot的Web Starter能够将Spring MVC需要的所有内容一站式添加到构建中,其中版本号继承自parent。
编写控制类:ContactController
package contacts;
import java.util.List;
import java.util.Map;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller
@RequestMapping("/")
public class ContactController {
private ContactRepository contactRepo;
@Autowired
public ContactController(ContactRepository contactRepo) {
this.contactRepo = contactRepo;
}
@RequestMapping(method=RequestMethod.GET)
public String home(Map<String,Object> model) {
List<Contact> contacts = contactRepo.findAll();
model.put("contacts", contacts);
return "home";
}
@RequestMapping(method=RequestMethod.POST)
public String submit(Contact contact) {
contactRepo.save(contact);
return "redirect:/";
}
}
模型类(POJO):Contact
package contacts;
public class Contact {
private Long id;
private String firstName;
private String lastName;
private String phoneNumber;
private String emailAddress;
public void setId(Long id) {
this.id = id;
}
public Long getId() {
return id;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getFirstName() {
return firstName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public String getLastName() {
return lastName;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setEmailAddress(String emailAddress) {
this.emailAddress = emailAddress;
}
public String getEmailAddress() {
return emailAddress;
}
}
创建视图
Thymeleaf的原生模板比JSP更加便于使用,而且它能够让我们以HTML的形式编写模板。
Spring Boot自动配置视图解析器、模板解析器、模板引擎。
控制类中的home()方法返回的逻辑视图名为home,所以模板文件应该命名为home.html,自动配置的模板解析器会在“src/main/resources/templates”下查找Thymeleaf模板。
Thymeleaf模板:home.html
<!DOCTYPE html>
<html xmlns:th="http://www.thymeleaf.org">
<head>
<title>Spring Boot Contacts</title>
<link rel="stylesheet" th:href="@{/style.css}" />
</head>
<body>
<h2>Spring Boot Contacts</h2>
<form method="POST">
<label for="firstName">First Name:</label>
<input type="text" name="firstName"></input><br/>
<label for="lastName">Last Name:</label>
<input type="text" name="lastName"></input><br/>
<label for="phoneNumber">Phone #:</label>
<input type="text" name="phoneNumber"></input><br/>
<label for="emailAddress">Email:</label>
<input type="text" name="emailAddress"></input><br/>
<input type="submit"></input>
</form>
<ul th:each="contact : ${contacts}">
<li>
<span th:text="${contact.firstName}">First</span>
<span th:text="${contact.lastName}">Last</span> :
<span th:text="${contact.phoneNumber}">phoneNumber</span>,
<span th:text="${contact.emailAddress}">emailAddress</span>
</li>
</ul>
</body>
</html>
添加静态内容
当采用Spring Boot的Web自发配置来定义Spring MVC bean时,这些bean中包含了一个资源处理器,它会将“/**”映射到几个资源路径中。
- /META-INF/resources/
- /resources/
- /static/
- /public/
静态资源style.css样式表:
body {
background-color: #eeeeee;
font-family: sans-serif;
}
label {
display: inline-block;
width: 120px;
text-align: right;
}
持久化数据
使用H2数据库和JDBC(使用Spring的JdbcTemplate)
编写Repository类:
package contacts;
import java.util.List;
import java.sql.ResultSet;
import java.sql.SQLException;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.RowMapper;
import org.springframework.stereotype.Repository;
@Repository
public class ContactRepository {
private JdbcTemplate jdbc;
@Autowired
public ContactRepository(JdbcTemplate jdbc) {
this.jdbc = jdbc;
}
public List<Contact> findAll() {
return jdbc.query(
"select id, firstName, lastName, phoneNumber, emailAddress " +
"from contacts order by lastName",
new RowMapper<Contact>() {
public Contact mapRow(ResultSet rs, int rowNum) throws SQLException {
Contact contact = new Contact();
contact.setId(rs.getLong(1));
contact.setFirstName(rs.getString(2));
contact.setLastName(rs.getString(3));
contact.setPhoneNumber(rs.getString(4));
contact.setEmailAddress(rs.getString(5));
return contact;
}
}
);
}
public void save(Contact contact) {
jdbc.update(
"insert into contacts " +
"(firstName, lastName, phoneNumber, emailAddress) " +
"values (?, ?, ?, ?)",
contact.getFirstName(), contact.getLastName(),
contact.getPhoneNumber(), contact.getEmailAddress());
}
}
创建contacts表:
如果将该文件命名为schema.sql并将其放在类路径根下(“src/main/resources”),当应用启动时,就会找到这个文件并进行数据加载。
create table contacts (
id identity,
firstName varchar(30) not null,
lastName varchar(50) not null,
phoneNumber varchar(13),
emailAddress varchar(30)
);
启动应用
初始化spring boot配置的启动类:
package contacts;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.context.annotation.ComponentScan;
@ComponentScan
@EnableAutoConfiguration
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
spring-boot-starter-web依赖会创建内嵌的Tomcat依赖,所以直接运行启动类即可。
