摘要

Phalcon VS Spring 用法對照表

目錄

1. Install

1.1. Phalcon

FYI https://github.com/oscm/shell/blob/master/lang/php/pecl/phalcon.sh

You need to install with compiler, make tools.

			
#!/bin/sh
cd /usr/local/src/

git clone --depth=1 git://github.com/phalcon/cphalcon.git
cd cphalcon/build
./install

cat > /srv/php/etc/conf.d/phalcon.ini <<EOF
extension=phalcon.so
EOF

1.2. Spring

You just only create a file as pom.xml, the maven will be fetch them.

3. Controller

3.1. welcome

3.1.1. Phalcon

				
<?php

class IndexController extends ControllerBase
{

    public function indexAction()
    {

    }
    public function welcomeAction()
    {
    	$message = "Helloworld!!!";
		$this->view->setVar('message',$message);
    }

}

3.1.2. Spring

				
package cn.netkiller.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class Welcome {

	@RequestMapping("/welcome")
	public ModelAndView helloWorld() {

		String message = "Helloworld!!!";
		return new ModelAndView("welcome", "message", message);
	}
}

3.2. pathinfo

http://www.netkiller.cn/news/list/100.html

http://www.netkiller.cn/news/detail/100/1000.html

3.2.1. Phalcon

				
<?php

class NewsController extends \Phalcon\Mvc\Controller
{


    public function listAction($category_id)
    {
		$this->view->setVar('category_id',$category_id);
    }
    public function detailAction($category_id, $article_id)
    {
		$this->view->setVar('category_id',$category_id);
		$this->view->setVar('article_id',$article_id);
    }

}

3.2.2. Spring

				
package cn.netkiller.controller;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class Pathinfo {
	@RequestMapping("/news/list/{category_id}")
	public ModelAndView urlTestId(@PathVariable String category_id) {

		return new ModelAndView("news/list", "category_id", category_id);
	}

	@RequestMapping("/news/detail/{category_id}/{article_id}")
	public ModelAndView urlTestId(@PathVariable String category_id, @PathVariable String article_id) {

		ModelMap model = new ModelMap();

		model.addAttribute("category_id", category_id);
		model.addAttribute("article_id", article_id);

		return new ModelAndView("news/detail", model);
	}
}

3.3. HTTP Get

http://www.netkiller.cn/member/login?email=netkiller@msn.com

3.3.1. Phalcon

				
<?php

class MemberController extends ControllerBase
{

    public function loginAction()
    {
		echo "email=" . $request->get("email");
    }

}

3.3.2. Spring

				
package cn.netkiller.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class Welcome {

	@RequestMapping("/member/login")
	@ResponseBody
	public String getEmailWithRequestParam(@RequestParam("email") String email) {
	    return "email=" + email;
	}

}

如果參數很多寫起來就非常辛苦

				
package cn.netkiller.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class Welcome {

	@RequestMapping("/member/login")
	@ResponseBody
	public String getEmailWithRequestParam(
		@RequestParam("email") String email
		@RequestParam("password") String password
		...
		...
		@RequestParam("ext") String ext
	) {
	    ...
	    ...
	    ...
	}

}

3.4. HTTP Post

3.4.1. Phalcon

				
<?php

class MemberController extends ControllerBase
{

    public function loginAction()
    {
		echo "email=" . $request->getPost("email");
		echo "password=" . $request->getPost("password");
		echo "phone=" . $request->getPost("phone");
    }

}

3.4.2. Spring

				
package cn.netkiller.controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;

import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class Member {

	@RequestMapping("/http/form")
	public ModelAndView createCustomer(){
		ModelMap model = new ModelMap();

		model.addAttribute("email", "netkiller@msn.com");
		model.addAttribute("phone", "13113668890");
		
	    return new ModelAndView("http/form", model);
	}	
	
	@RequestMapping(value= "/http/post", method = RequestMethod.POST)
	public ModelAndView saveCustomer(HttpServletRequest request, 
	        @RequestParam(value="Email", required=false) String email, 
	        @RequestParam(value="Password", required=false) String password, 
	        @RequestParam(value="Phone", required=false) String phone){

		ModelMap model = new ModelMap();

		model.addAttribute("email", email);

7. Cache

7.1. Redis

7.1.1. Phalcon

				
//Cache arbitrary data
 $this->cache->save('my-key', array(1, 2, 3, 4, 5));

 //Get data
 $data = $this->cache->get('my-key');

7.1.2. Spring

pom.xml

				
<dependencies>
    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-redis</artifactId>
        <version>1.6.1.RELEASE</version>
    </dependency>
</dependencies>

Configure RedisTemplate....

				
<bean id="jedisConnFactory" 
    class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" 
    p:use-pool="true"/>

<!-- redis template definition -->
<bean id="redisTemplate" 
    class="org.springframework.data.redis.core.RedisTemplate" 
    p:connection-factory-ref="jedisConnFactory"/>

Testing

				
public class Example {

    // inject the actual template
    @Autowired
    private RedisTemplate<String, String> template;

    // inject the template as ListOperations
    // can also inject as Value, Set, ZSet, and HashOperations
    @Resource(name="redisTemplate")
    private ListOperations<String, String> listOps;

    public void addLink(String userId, URL url) {
        listOps.leftPush(userId, url.toExternalForm());
        // or use template directly
        redisTemplate.boundListOps(userId).leftPush(url.toExternalForm());
    }
}

7.2. Model + Cache

7.2.1. Phalcon

				
   	$articles = Article::find(array(
   			"cache" => array("service"=> 'redis', "key" => $key, "lifetime" => 60)
   	));

7.2.2. MyBatis

MyBatis Redis Cache adapter http://mybatis.github.io/redis-cache

7.3. Phalcon vs Ehcache

7.3.1. 

7.3.2. 

8. JSON Data

8.1. Phalcon

Encode

			
<?php

$json = array(
	'contact' => array(
		'name' 		=> 'Neo',
		'website' 	=> 'http://www.netkiller.cn',
		'nickname' 	=> 'netkiller' 
	) 
); 
print(json_encode($json));

Output

{"contact":{"name":"Neo","website":"http:\/\/www.netkiller.cn","nickname":"netkiller"}}

Decode

			
<?php
$string = '{"contact":{"name":"Neo","website":"http:\/\/www.netkiller.cn","nickname":"netkiller"}}';
print_r(json_decode($string));

輸出

			
stdClass Object
(
    [contact] => stdClass Object
        (
            [name] => Neo
            [website] => http://www.netkiller.cn
            [nickname] => netkiller
        )

)

8.2. Spring

JSON 編碼

			
package netkiller.json;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;

import javax.json.*;

public final class Writer {

	public static void main(String[] args) {
		// TODO Auto-generated method stub

		JsonObjectBuilder jsonBuilder = Json.createObjectBuilder();
		JsonObjectBuilder addressBuilder = Json.createObjectBuilder();
		JsonArrayBuilder phoneNumBuilder = Json.createArrayBuilder();

		phoneNumBuilder.add("12355566688").add("0755-2222-3333");

		addressBuilder.add("street", "Longhua").add("city", "Shenzhen").add("zipcode", 518000);

		jsonBuilder.add("nickname", "netkiller").add("name", "Neo").add("department", "IT").add("role", "Admin");

		jsonBuilder.add("phone", phoneNumBuilder);
		jsonBuilder.add("address", addressBuilder);

		JsonObject jsonObject = jsonBuilder.build();

		System.out.println(jsonObject);

		try {
			// write to file
			File file = new File("json.txt");
			if (!file.exists()) {
				file.createNewFile();
			}
			OutputStream os = null;
			os = new FileOutputStream(file);
			JsonWriter jsonWriter = Json.createWriter(os);
			jsonWriter.writeObject(jsonObject);
			jsonWriter.close();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	}

}
		
運行後輸出
