### **默认的Favicon** ###

Spring Boot提供了一个默认的Favicon，每次访问应用的时候都能看到。

![默认的Favicon][Favicon]

### **关闭Favicon** ###

我们可以在application.properties中设置关闭Favicon，默认为开启。

spring.mvc.favicon.enable=false

或在application.yml中设置关闭Favicon

spring:
      mvc:
        favicon:
          enabled: false

### **设置自己的Favicon** ###

若需要设置自己的Favicon，则只需将自己的favicon.ico文件放置在类路径根目录、类路径META-INF/resources/下、类路径resources/下、类路径static/下或类路径public/下。

这里将favicon.ico放置在src/main/resources/static下。

### **源码分析** ###

application.properties

spring.mvc.favicon.enabled=false

IndexController .java

@Controller
    public class IndexController {
    
        @RequestMapping(value = "/index")
        public String index(Model model) {
            model.addAttribute("name","SpringBootFavicon");
            return "index";
        }
    }

IndexRestController .java

@RestController
    public class IndexRestController {
    
        @RequestMapping(value = "/indexRest")
        public String index() {
            return "indexRest";
        }
    }

RunApplication .java

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

运行RunApplication,java
