【springboot】搭建springboot项目

简单搭建

1 添加依赖spring-boot-starter-web

dependencies {
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-web', version: '2.3.5.RELEASE'
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

2 建立启动类 ApiApplicationContext（这一步项目可以启动）

@SpringBootApplication
public class ApiApplicationContext {

    public static void main(String[] args) {
        SpringApplication.run(ApiApplicationContext.class, args);
    }
}

 3 提供http接口 

@RestController//用友@Controller 、 @ResponseBody注解的功能
public class HelloController {

    @RequestMapping("/say-hello")
    public String sayHello(){
        return "hello";
    }
}

 4、渲染页面（freemarker）

添加依赖

dependencies {
    //springboot启动相关包
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-web', version: '2.3.5.RELEASE'
    //freemarker
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-freemarker', version: '2.3.5.RELEASE'

    testCompile group: 'junit', name: 'junit', version: '4.12'
}

添加路由

@Controller
@RequestMapping("/view")
public class PageController {

    @RequestMapping("/home-page")
    public String homePage(Model model) {
        model.addAttribute("name","mojing");
        return "home_page";
    }

}

 添加ftl页面 home_page.ftl

<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8" />
    <title></title>
</head>
<body>
hello: ${name}
</body>
</html>

 freemarker配置（application.yml）

spring:
  freemarker:
    template-loader-path: classpath:/templates/
    suffix: .ftl
    cache: false
    request-context-attribute: request
    content-type: text/html
