最近开始看Spring Boot，发现其开发起来真是方便。今天就来实现一个简单的Spring MVC 请求，纯Java代码的哦。
1、Maven必不可少，先看看都加载了那些依赖：
<?xml version="1.0" encoding="UTF-8"?>
<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/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.selrain</groupId>
<artifactId>chapter-1</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>
<name>chapter-1</name>
<description>Demo project for Spring Boot</description>
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.1.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
<java.version>1.8</java.version>
</properties>
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
//thymeleaf模板，待会用到
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>
</project>
2、Controller
@Controller
public class GreetingController {
@RequestMapping("/greeting")
public String greeting(String name, Model m){
m.addAttribute("name",name);
return "greeting";
}
}
3、页面，放在src/main/resources/templates/目录下，方便解析
<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
<meta charset="UTF-8"/>
<title>Title</title>
</head>
<body>
<p th:text="‘Hello, ‘ + ${name} + ‘!‘" />
</body>
</html>
4、最后是主程序入口：）
@SpringBootApplication
public class Chapter1Application {
public static void main(String[] args) {
SpringApplication.run(Chapter1Application.class, args);
}
}
最后，启动项目，在浏览器输入地址：http://localhost:8080/greeting?name=world 看看效果.
最最后。想要设置欢迎页的同学，在src/main/resources/创建index.html页面，当输入http://localhost:8080/ 程序就会自动跳入该页面啦
刚开始学哦，共同进步：）
