@EnableAutoConfiguration和@ComponentScan等于@SpringBootApplication

springboot

            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>
serve启动  不能放到src/main下，新建文件夹，或者和controller放一起
StartApp.java
@SpringBootApplication
public class StartApp {

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

pom.xml
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-freemarker</artifactId>
        </dependency>

freemarker controller

FreemarkerController.java

@Controller
public class FreemarkerController {

    @RequestMapping("/ftlIndex")
    public String ftlIndex(Model model){
        model.addAttribute("name", "zhangsan");
        model.addAttribute("sex", "0");
        return "ftlIndex";
    }
}

约定在src/main/resources/templates,将html放此路径

ftlIndex.html

<html>
<head>

</head>
<body>
    Hello World Freemarker!<br/>
    ${name}<br/>

    <#if sex="0">
男生
<#else>
女生
</#if>
</body>
</html>

springboot使用jsp必须引入外部tomcat,内部tomcat不支持

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-freemarker</artifactId>
</dependency>
