Spring Boot之简单的MVC
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:)
