1. Configure the maven file pom.xml

</project>

Copy after login

2. File structure (the names of static/templates/application.properties/logback.xml are all agreed, only You can use certain names. Please refer to the official spring boot documentation for details. The following name is one of the configuration methods)

3. Create a startup class (put it at the top level, sub Only classes in the lower layer (lower-level folder) can be scanned and injected)

@SpringBootApplication
public class Application {

    /**
     * main function
     * @param args params
     */
    public static void main(String[] args){
       SpringApplication.run(Application.class,args);
    }
}

Copy after login

4. Create a controller (in the lower-level directory of the Application class)

@Controller
@RequestMapping("/common")public class Common {

    @Value("${msg:Welcome!}")private String msg;/** * get a page
     * @return a page with name called return value     */@RequestMapping("login")public String getLoginPage(ModelMap map){
        map.put("welcomeMsg",this.msg);return "login";
    }


}

Copy after login

5. Create a web page template login.ftl (freemarker must use the ftl suffix, and I have been fooled by this for a long time! Put js/css and so on in the corresponding folders. Note that there is no /static in the access path, and I have also been fooled by this. It’s been a long time! )

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8" />
    <title>login</title>

    <link href="/css/home.css?1.1.11" rel="stylesheet" type="text/css" />
    <script type="text/javascript" src="/js/jquery-2.0.3.min.js?1.1.11"></script>
    <script type="text/javascript" src="/js/home.js?1.1.11"></script>
</head>
<body>
<h1>login page</h1>
<h2>${welcomeMsg}</h2>
<form>
    <div>
     <label>用户名:<input type="text" id="username"/></label>
    </div>
    <div>
     <label>密码:<input type="password"/></label>
    </div>
    <div>
        <input type="submit" value="提交"/>
        <input type="reset" value="重置" />
    </div>
</form>
</body>
</html>

Copy after login

6. Write the application configuration file

Create a new application.properties file and add the following content

msg=Ladies and gentleman,Welcome!

7. Start running

and visit in the browser: http://localhost:8080/common/login

8. Deployment

mvn package Make a package

java -jar xxx.jar Run this package
