app + controller分離:
<1>controller使用:
@RestController:
整合了@Controller和@ResponseBody,加入了restful特性。
package org.jin.springboot3.controller;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
//@Controller
@RestController
public class BookController {
@RequestMapping("/{path}")
//@ResponseBody
public String show(@PathVariable String path) {
return "show : " + path;
}
}
<2>app使用:
@SpringBootApplication:
整合了@EnableAutoConfigure和@ComponentScan,可以同時包含多個controller。
package org.jin.springboot3.app;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
//@EnableAutoConfiguration
//@ComponentScan("org.jin.springboot3.controller")
@SpringBootApplication(scanBasePackages={"org.jin.springboot3.controller"})
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
