SpringBoot入门demo(一)

先上代码

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.sky.entity.SkyUserEntity;

/**

 *
 */
@SpringBootApplication
@RestController
@RequestMapping("/app")
public class Application {

	@RequestMapping("/")
	public String index(){
		return "Index Page";
	}
	
	@RequestMapping("/hello")
	public String hello(){
		return "Hello Word!";
	}
	
	@RequestMapping("/users/{username}")
	public String userProfile(@PathVariable("username")String username){
		return String.format("username %s", username);
	}
	
	@RequestMapping("/posts/{id}")
	public String post(@PathVariable("id") int id){
		return String.format("post %s", id);
	}
	
	@RequestMapping(value = "/login",method=RequestMethod.GET)
	public String loginGet(){
		return "Login Page";
	}
	
	@RequestMapping(value = "/login",method=RequestMethod.POST)
	public SkyUserEntity loginPost(String username,String password){
		SkyUserEntity po = new SkyUserEntity();
		po.setUsername(username);
		po.setPassword(password);
		return po;
	}
	
	
	
	public static void main(String[] args) {
		SpringApplication.run(Application.class, args);
	}
	

import java.io.Serializable;

/**

 */
@SuppressWarnings("serial")
public class SkyUserEntity implements Serializable{

	private String username;
	
	private String password;

	public String getUsername() {
		return username;
	}

	public void setUsername(String username) {
		this.username = username;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}
	
	
}

启动项目 看到这样的表示成功

http://localhost:8080/app/

可以看到 Index Page

http://localhost:8080/app/hello

Hello Word!

http://localhost:8080/app/users/123232

username 123232

http://localhost:8080/app/posts/123232

post 123232

自己试试 post请求

http://localhost:8080/app/login

Login Page

上post请求的html代码

 
  
  
  
  
  
  
 

 
  
  

    

        

            
账号：
            

        
        

            
密码：
            

        
        

            

                
                
            
        
    
 
 

相应结果

{

username:  "hellow",

password:  "1234567890"

}

由于我们Application用上了@RestController注解所以我们不用在方法上写@ResponseBody
