使用Spring-tool-suit搭建SpringBoot+Zookeeper+dubbo(Windows)

Posted 2021-02-27 alittlecomputer

我的整个搭建用了三个服务器

Zookeeper在10.160.192.164

生产者在10.160.196.0

消费者在10.121.252.209

一、安装Zookeeper

在这里下载https://zookeeper.apache.org/releases.html

我下载的是3.6.0版本。apache-zookeeper-3.6.0-bin.tar.gz

解压出来是apache-zookeeper-3.6.0-bin

修改配置文件：

在apache-zookeeper-3.6.0-bin\\conf下面有zoo_sample.cfg,把这个文件做一个备份，然后改名为zoo.cfg.因为zookeeper启动后，只认识zoo.cfg的所有设置和配置。

在zoo.cfg中输入：

# The number of milliseconds of each tick
tickTime=2000
# The number of ticks that the initial 
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between 
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
# do not use /tmp for storage, /tmp here is just 
# example sakes.
dataDir=D:\\zookeeper3.6.0\\data
dataLogDir=D:\\zookeeper3.6.0\\log
# the port at which the clients will connect
clientPort=2181
# the maximum number of client connections.
# increase this if you need to handle more clients
#maxClientCnxns=60
#
# Be sure to read the maintenance section of the 
# administrator guide before turning on autopurge.
#
# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
#
# The number of snapshots to retain in dataDir
#autopurge.snapRetainCount=3
# Purge task interval in hours
# Set to "0" to disable auto purge feature
#autopurge.purgeInterval=1

## Metrics Providers
#
# https://prometheus.io Metrics Exporter
#metricsProvider.className=org.apache.zookeeper.metrics.prometheus.PrometheusMetricsProvider
#metricsProvider.httpPort=7000
#metricsProvider.exportJvmInfo=true

主要是配置了dataDir的路径和dataLogDir的路径。

 然后在D盘创建这些文件夹

D:\\zookeeper3.6.0\\data

D:\\zookeeper3.6.0\\log

默认不创建会自动创建，自己创建以免万一。

使用CMD，进入apache-zookeeper-3.6.0-bin文件夹，运行zkServer.cmd，启动服务，如下图所示（port：2181是zookeeper的专用监听端口）

创建项目生产者：
项目结构：

 

 

创建流程：
File->new->other->SpringBoot->Spring Starter Project,Next
填写相应的信息：Next

 

 选择依赖web，Finish

 

 4、pom.xml，注意：dubbo内部强制要用log4j，所以此处加上log4j的依赖

 application.properties

spring.dubbo.application.name=provider
spring.dubbo.registry.address=zookeeper://10.160.192.164:2181
spring.dubbo.protocol.name=dubbo
spring.dubbo.protocol.port=20880
spring.dubbo.scan=com.hzg.boot.server.dubbo

创建这些相关类：

 

 

 Employee.java

package com.hzg.boot.server.entity;

import java.io.Serializable;

public class Employee implements Serializable{
    private static final long serialVersionUID = 1L;
    private Integer id;
    private String employee_name;
    private String employee_age;
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getEmployee_name() {
        return employee_name;
    }
    public void setEmployee_name(String employee_name) {
        this.employee_name = employee_name;
    }
    public String getEmployee_age() {
        return employee_age;
    }
    public void setEmployee_age(String employee_age) {
        this.employee_age = employee_age;
    }
    @Override
    public String toString() {
        return "Employee [id=" + id + ", employee_name=" + employee_name + ", employee_age=" + employee_age + "]";
    }
    public Employee(Integer id, String employee_name, String employee_age) {
        super();
        this.id = id;
        this.employee_name = employee_name;
        this.employee_age = employee_age;
    }
    
    

}

EmployeeService.java

package com.hzg.boot.server.dubbo;

import com.hzg.boot.server.entity.Employee;

public interface EmployeeService {
    
    Employee queryEmployeeByName(String employeeName);

}

EmployeeServiceImpl.java

package com.hzg.boot.server.dubbo.impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.hzg.boot.server.dubbo.EmployeeService;
import com.hzg.boot.server.entity.Employee;

@Service(version="1.0.0")
public class EmployeeServiceImpl implements EmployeeService{

    @Override
    public Employee queryEmployeeByName(String employeeName) {
        // TODO Auto-generated method stub
        return new Employee(1,"上海","大城市");
    }

}

7、打包项目并运行，右击项目-Run As-Maven clean,成功之后再Run As-Maven build-Goals中输入compile

启动SpringbootDubboServerApplication

 

 

搭建消费者：

项目结构：

 

 添加相关的类：

application.properties

#防止服务消费者和提供者端口冲突(一致)
server.port=8888
## Dubbo 消费者  
spring.dubbo.application.name=consumer
spring.dubbo.registry.address=zookeeper://10.160.192.164:2181
spring.dubbo.scan=com.hzg.boot.server.dubbo

EmployeeService

package com.hzg.boot.server.dubbo;

import com.hzg.boot.server.entity.Employee;

public interface EmployeeService {
    Employee queryEmployeeByName(String employeeName);
}

EmployeeConsumerService 

package com.hzg.boot.server.dubbo;

import org.springframework.stereotype.Component;

import com.alibaba.dubbo.config.annotation.Reference;
import com.hzg.boot.server.entity.Employee;

@Component
public class EmployeeConsumerService {
    
    @Reference(version="1.0.0")
    EmployeeService employeeService;

    public EmployeeService getEmployeeService() {
        return employeeService;
    }

    public void setEmployeeService(EmployeeService employeeService) {
        this.employeeService = employeeService;
    }
    
    public void printEmployee() {
        String employeeName="上海";
        if(employeeService == null) {
            System.out.println("employeeService服务对象为空");
        }else {
            Employee employee = employeeService.queryEmployeeByName(employeeName);
            System.out.println(employee.toString());
        }
    }

}

Employee

package com.hzg.boot.server.dubbo;

import org.springframework.stereotype.Component;

import com.alibaba.dubbo.config.annotation.Reference;
import com.hzg.boot.server.entity.Employee;

@Component
public class EmployeeConsumerService {
    
    @Reference(version="1.0.0")
    EmployeeService employeeService;

    public EmployeeService getEmployeeService() {
        return employeeService;
    }

    public void setEmployeeService(EmployeeService employeeService) {
        this.employeeService = employeeService;
    }
    
    public void printEmployee() {
        String employeeName="上海";
        if(employeeService == null) {
            System.out.println("employeeService服务对象为空");
        }else {
            Employee employee = employeeService.queryEmployeeByName(employeeName);
            System.out.println(employee.toString());
        }
    }

}

在SpringbootDubboClientApplication中添加代码：

package com.hzg.boot.server;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;

import com.hzg.boot.server.dubbo.EmployeeConsumerService;

//import com.hzg.boot.client.dubbo.EmployeeConsumerService;


@SpringBootApplication
public class SpringbootDubboClientApplication {

    public static void main(String[] args) {
        ConfigurableApplicationContext run =  SpringApplication.run(SpringbootDubboClientApplication.class, args);
        EmployeeConsumerService employeeService = run.getBean(EmployeeConsumerService.class);
        System.out.println(employeeService);
        employeeService.printEmployee();
    }

}

 

6、启动项目，和Server一致，注意先启动生产者，再启动消费者

控制台会打印相关的信息：
