順便記錄下apache產品提供下載的網址：http://mirrors.shuosc.org/apache/java

 

第一步：git

下載zookeeper，網址：http://mirrors.shuosc.org/apache/zookeeper/程序員

啓動zookeeper，直接解壓後，打開bin目錄，雙擊zkServer.cmd，啓動zookeeper服務。github

若啓動失敗，我遇到的，有幾個種緣由，詳情請打開cmd文件，在endlocal以前添加  pause  ，這樣就不會閃退。web

一、沒配置java環境，在環境變量中，要JAVA_HOME這樣配置變量，不能直接在path貼jdk路徑。spring

二、在conf目錄，將zoo_sample.cfg文件名修改爲zoo.cfg。apache

 

第二步：api

建立MAVEN JAVA工程，以下建立一個dubbo，一個接口模塊，一個程序入口（SPRINGMVC）spring-mvc

 

 

三、interface項目，只要寫一個類mvc

package com.cwj.inter;

import org.springframework.stereotype.Service;

@Service
public interface DemoService {

    public String sayHello(String name);
    
}

 

pom.xml添加註釋依賴

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.cwj</groupId>
  <artifactId>interface</artifactId>

  <packaging>jar</packaging>

  <name>interface</name>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>

        <dependency>

            <version>4.0.2.RELEASE</version>
        </dependency>
  </dependencies>
</project>

 

 

四、dubbo項目

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <packaging>jar</packaging>

    <name>dubbo</name>
    <url>http://maven.apache.org</url>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

        <!-- Logging -->

        <slf4j-log4j12.version>1.7.5</slf4j-log4j12.version>
        <log4j.version>1.2.17</log4j.version>
    </properties>

    <dependencies>
        <!-- Logging with SLF4J -->
        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>slf4j-api</artifactId>

        </dependency>

            <scope>compile</scope>
            <exclusions>
                <exclusion>

                    <groupId>org.springframework</groupId>
                </exclusion>
            </exclusions>
        </dependency>

        <!-- SPRING 解析XML-->

  <artifactId>interface</artifactId>
  <version>0.0.1-SNAPSHOT</version>
        </dependency>
    </dependencies>
</project>

 

建立DemoServiceImpl類，繼承DemoService

package com.cwj.dubbo;

import com.cwj.inter.DemoService;

public class DemoServiceImpl implements DemoService{

    public String sayHello(String name) {
        // TODO Auto-generated method stub
        System.out.println("hello:"+name);
        return "hello,"+name;
    }
    
}

 

 

配置applicationProvider.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:dubbo="http://code.alibabatech.com/schema/dubbo"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
     http://www.springframework.org/schema/beans/spring-beans.xsd        
     http://code.alibabatech.com/schema/dubbo        
     http://code.alibabatech.com/schema/dubbo/dubbo.xsd">
 
 
     <!-- 提供方應用信息，用於計算依賴關係 -->
    <dubbo:application name="app-provider"  />
 
    <!-- 使用zookeeper註冊中心暴露服務地址 -->
    <dubbo:registry address="zookeeper://127.0.0.1:2181" /> 
 
    <!-- 用dubbo協議在20880端口暴露服務 -->
    <dubbo:protocol name="dubbo" port="20880" />

    <!-- 聲明須要暴露的服務接口 -->
    <dubbo:service interface="com.cwj.inter.DemoService" ref="demoService" />
 
    <!-- 和本地bean同樣實現服務 -->
    <bean id="demoService" class="com.cwj.dubbo.DemoServiceImpl" />
 
     
     
 </beans>

 

在App類中添加啓動方法

package com.cwj.dubbo;

import java.io.IOException;

import org.springframework.context.support.ClassPathXmlApplicationContext;

/**
 * Hello world!
 *
 */
public class App {

    public static void main(String[] args) throws IOException {

        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext("applicationProvider.xml");
        context.start();
        
        System.out.println("-----dubbo開啓-----");
        
        System.in.read(); // 爲保證服務一直開着，利用輸入流的阻塞來模擬

    }


}

 

開心的話也能夠添加log4j.properties配置文件，沒有配置有警告。程序員眼裏只有錯誤把。

log4j.rootLogger=INFO,Console,File  
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
log4j.appender.Console.layout = org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n  
  
log4j.appender.File = org.apache.log4j.RollingFileAppender  
log4j.appender.File.File = logs/ssm.log  
log4j.appender.File.MaxFileSize = 10MB  
log4j.appender.File.Threshold = ALL  
log4j.appender.File.layout = org.apache.log4j.PatternLayout  
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

 

運行APP的main方法就能夠成功啓動了。啓動前要先打開zk服務。

 

第五步：protal項目，配置MVC

啓動項目成功鏈接，不想測試了。之後寫博客儘可能不貼代碼。把本身遇到的問題給記錄下來。 哪怕是幾句話。

這個是一個過渡。加油。
