dubbo是阿里巴巴的框架�Q�主要有4部分�l�成�Q? 服务台提供方�Q?2 服务注册�?3 服务消费�?4 监控部分

1. 注册方一般用zookeeper, 先下载安装，启动zkservece.cmd 会报错，需要修攚w��|�文�?zoo.cfg. 路径中conf/下，�Q�没有自己加一个�?br />正常启动

2. �~�写一个服务器�? 创徏maven��目

IProcessData定义接口及实现类

package cn.zto.service.impl;

import cn.zto.service.IProcessData;
public class ProcessDataImpl implements IProcessData {
public String hello(String name) {
System.out.println(name);
return "hello : " + name;
}}

package cn.zto.service;

public interface IProcessData {
public String hello(String name);
}

启动服务

package cn.zto.app;

import org.springframework.context.support.ClassPathXmlApplicationContext;
public class Main {
public static void main(String[] args) throws Exception {
ClassPathXmlApplicationContext context=new ClassPathXmlApplicationContext( new String[] {
"config/applicationProvider.xml"
});
context.start();
System.out.println("按�Q意键退�?);
System.in.read();
}}

�q�行��h��。如�?/span>

�q�行�l�果如下

spring boot

Wed, 04 May 2016 07:39:00 GMT

spring boot 是spring 4.0提供的微框架�Q�支�?jdk 1.8, maven 3以上, 否则会报一些错误�?br />
1. pom 文�g�Q?主要写依赖关�p�，

   xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
   4.0.0
   com.example
   spring-boot
   0.0.1-SNAPSHOT
   spring-boot-example


       org.springframework.boot
       spring-boot-starter-parent
       1.3.3.RELEASE






           org.springframework.boot
           spring-boot-starter-web








           spring-snapshots
           http://repo.spring.io/libs-snapshot





           spring-snapshots
           http://repo.spring.io/libs-snapshot






               org.springframework.boot
               spring-boot-maven-plugin




2. 然后��是提供的接口类UserController�Q?实体�c�User�Q?主要是几个注�?/span>
@RestController   l�c�d��spring mvc 的@Controller
@RequestMapping   �c�d��spring mvc

package two;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/user")

public class UserController {

   @RequestMapping("/hello")
   public User view(){

       User user=new User();
       user.setId((long)100);
       user.setName("fanjs");
       return user;


   }

package two;

public class User {
private Long id;
private String name;
public Long getId() {
   return id;
}
public void setId(Long id) {
   this.id = id;
}
public String getName() {
   return name;
}
public void setName(String name) {
   this.name = name;
}

3. 然后��是�E�序启动�Q�这里不需要spring xml文�g�Q�完全依赖注解�?/span>
@EnableAutoConfiguration
@Configuration
@ComponentScan

package two;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan
@EnableAutoConfiguration

public class RunMain {

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

       SpringApplication.run(RunMain.class, args);
   }

}

4. ��试路径

http://localhost:8080/user/hello

{"id":100,"name":"fanjs"}
