微服务项目 -- day01 项目准备与搭建、基础微服务项目功能实现

一、项目开发前环境准备

1、开发环境要求

JDK1.8

数据库mysql 5.7

开发工具 idea 2017.1.2

maven版本3.3.9

docker 最新版本

centos7（资料中有已经安装好的虚拟机，直接导入VMWare中，将内存调整到8G，该虚拟机中已经安装好docker，并且已经设置开机启动，并且已经安装好项目中所用到的所有docker镜像）

2、虚拟机中创建数据表

（1）、使用docker创建mysql容器环境

docker run -di --name=tensquare_mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=123456 centos/mysql-57-centos7

说明：以上创建命令创建出来的docker的mysql环境可以使用本地的mysql连接工具进行连接，端口号是3306，密码是123456

（2）、导入数据

3、安装postman测试工具

软件下载地址：https://download.csdn.net/download/wingzhezhe/10530924

4、IDEA安装JDK

5、IDEA配置Maven本地仓库

（1）、只针对当前项目有效的配置方式

（2）、配置全局的maven仓库方式

二、项目环境搭建

1、搭建父工程

（1）、父工程搭建

父工程中的src文件夹无用，将其删除

（2）、pom.xml文件中加入必要依赖

    4.0.0

    com.scf
    scf_parent
    1.0-SNAPSHOT

    pom

    scf_parent
    十次方项目

    
    
        org.springframework.boot

                false
            
        
    

（3）、选择自动导入依赖（加入坐标后自动导入对应的依赖jar包）

2、搭建公共子模块

（1）、搭建子模块

（2）、公共子模块中创建通用返回结果实体类

StatusCode.java

package entity;

/**
 * 返回结果状态码实体类
 */
public class StatusCode {
    public static final int OK = 20000;
    public static final int ERROR = 20001;
    public static final int LOGINERROR = 20002;     //用户名或密码错误
    public static final int ACCESSERROR = 20003;    //权限不足
    public static final int REMOTEERROR = 20004;    //远程调用失败
    public static final int REPEERROR = 20005;      //重复操作

}

Result.java

package entity;

import jdk.nashorn.internal.objects.annotations.Setter;

/**
 * 通用返回结果实体类
 */
public class Result {
    private boolean flag;   //是否成功
    private Integer code;   //返回码
    private String message; //返回结果信息
    private Object data;    //返回数据

    public Result(Object data) {
    }

    public Result(boolean flag, Integer code, String message, Object data) {
        this.flag = flag;
        this.code = code;
        this.message = message;
        this.data = data;
    }
    
    getter/Setter

    @Override
    public String toString() {
        return "Result{" +
                "flag=" + flag +
                ", code=" + code +
                ", message='" + message + '\'' +
                ", data=" + data +
                '}';
    }
}

PageResult.java

package entity;

import java.util.List;

/**
 * 分页数据返回结果实体类
 */
public class PageResult {
    private Long total;
    private List rows;

    setter/Getter
}

（3）、加入分布式ID生成器工具类（雪花算法）

package util;

import java.lang.management.ManagementFactory;
import java.net.InetAddress;
import java.net.NetworkInterface;

/**
 * 
名称：IdWorker.java
 * 
描述：分布式自增长ID
 * 
 *     Twitter的 Snowflake　JAVA实现方案
 * 
 * 核心代码为其IdWorker这个类实现，其原理结构如下，我分别用一个0表示一位，用—分割开部分的作用：
 * 1||0---0000000000 0000000000 0000000000 0000000000 0 --- 00000 ---00000 ---000000000000
 * 在上面的字符串中，第一位为未使用（实际上也可作为long的符号位），接下来的41位为毫秒级时间，
 * 然后5位datacenter标识位，5位机器ID（并不算标识符，实际是为线程标识），
 * 然后12位该毫秒内的当前毫秒内的计数，加起来刚好64位，为一个Long型。
 * 这样的好处是，整体上按照时间自增排序，并且整个分布式系统内不会产生ID碰撞（由datacenter和机器ID作区分），
 * 并且效率较高，经测试，snowflake每秒能够产生26万ID左右，完全满足需要。
 * 

 * 64位ID (42(毫秒)+5(机器ID)+5(业务编码)+12(重复累加))
 *

            System.out.println(" getDatacenterId: " + e.getMessage());
        }
        return id;
    }

}

三、基础微服务模块项目

1、搭建基础微服务模块项目

（1）、模块搭建同scf_common模块

（2）、pom.xml中加入依赖坐标

    
        scf_parent
        com.scf
        1.0-SNAPSHOT
    
    4.0.0

    scf_base


    
        
        
            org.springframework.boot
            spring-boot-starter-data-jpa
        
        
        
            mysql
            mysql-connector-java
        
        
        
            com.scf
            scf_common
            1.0-SNAPSHOT
        
    

（3）、创建启动类

package com.scf.base;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import util.IdWorker;

/**
 * springboot启动类
 */
@SpringBootApplication
public class BaseApplication {
    public static void main(String[] args) {
        SpringApplication.run(BaseApplication.class);
    }

    /**
     * 初始ID的雪花生成器
     */
    @Bean
    public IdWorker idWorker(){
        return new IdWorker(1, 1);
    }
}

（4）、加入配置文件 application.yml

# 配置tomcat端口号
server:
  port: 9001
# 配置注册中心中当前应用名称，名称不要有下划线_
spring:
  application:
    name: scf-base
  datasource:
    url: jdbc:mysql://192.168.37.133:3306/tensquare_base?characterEncoding=utf-8
    driver-class-name: com.mysql.jdbc.Driver
    username: root
    password: 123456
  jpa:
    show-sql: true
    database: mysql

2、实现标签管理的CRUD功能

（1）、创建基础微服务项目中的实体类

Label.java

package com.scf.base.pojo;

import javax.persistence.Entity;
import javax.persistence.Id;
import javax.persistence.Table;
import java.io.Serializable;

/**
 * 标签实体类，对应数据库tensquare_base中的tb_label表
 */
@Entity
@Table(name = "tb_label")
public class Label implements Serializable {

    @Id
    private String id;  //主键
    private String labelname;   //标签名称
    private String state;       //状态
    private Long count;     //使用数量
    private String recommend;   //是否推荐
    private Long fans;      //关注数

    public Label(String id, String labelname, String state, Long count, String recommend, Long fans) {
        this.id = id;
        this.labelname = labelname;
        this.state = state;
        this.count = count;
        this.recommend = recommend;
        this.fans = fans;
    }

    public Label() {
    }

   setter/getter

    @Override
    public String toString() {
        return "Label{" +
                "id='" + id + '\'' +
                ", labelname='" + labelname + '\'' +
                ", state='" + state + '\'' +
                ", count=" + count +
                ", recommend='" + recommend + '\'' +
                ", fans=" + fans +
                '}';
    }
}

（2）、编写数据访问层代码

LabelDao.java

package com.scf.base.dao;

import com.scf.base.pojo.Label;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.JpaSpecificationExecutor;

/**
 * 标签的数据访问层接口
 */
public interface LabelDao extends JpaRepository, JpaSpecificationExecutor {

}

（3）、编写业务实现层代码

LabelService.java

package com.scf.base.service;

import com.scf.base.dao.LabelDao;
import com.scf.base.pojo.Label;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import util.IdWorker;

import java.util.List;

/**
 * 标签业务层
 */
@Service
public class LabelService {

    @Autowired
    private LabelDao labelDao;

    @Autowired
    private IdWorker idWorker;

    /**
     * 查询所有标签列表
     * @return
     */
    public List findAll(){
        return labelDao.findAll();
    }

    /**
     * 根据id查询标签对象
     * @param id
     * @return
     */
    public Label findById(String id){
        return labelDao.findById(id).get();
    }

    /**
     * 添加标签
     * @param label
     */
    public void addLabel(Label label){
        label.setId(idWorker.nextId() + "");
        labelDao.save(label);
    }

    /**
     * 更新标签
     * @param label
     */
    public void updateLabel(Label label){
        labelDao.save(label);
    }

    /**
     * 根据id删除标签
     * @param id
     */
    public void delLabelById(String id){
        labelDao.deleteById(id);
    }
}

（4）、编写web层代码

LabelController.java

package com.scf.base.controller;

import com.scf.base.pojo.Label;
import com.scf.base.service.LabelService;
import entity.Result;
import entity.StatusCode;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.*;

import java.util.List;

/**
 * 标签web层
 */
@RestController
@RequestMapping("/label")
@CrossOrigin    //解决跨域请求问题
public class LabelController {

    @Autowired
    private LabelService labelService;

    /**
     * get请求查询所有标签列表
     *
     * @return
     */
    @RequestMapping(method = RequestMethod.GET)
    public Result findAll() {
        List labelList = labelService.findAll();
        return new Result(true, StatusCode.OK, "查询成功", labelList);
    }

    /**
     * get请求的根据id查询
     *
     * @param id
     * @return
     */
    @RequestMapping(value = "/{id}", method = RequestMethod.GET)
    public Result findById(@PathVariable String id) {
        Label label = labelService.findById(id);
        return new Result(true, StatusCode.OK, "查询成功", label);
    }

    /**
     * POST方式的增加
     *
     * @param label
     * @return
     */
    @RequestMapping(method = RequestMethod.POST)
    public Result add(@RequestBody Label label) {
        labelService.addLabel(label);
        return new Result(true, StatusCode.OK, "添加成功", null);
    }

    /**
     * 根据ID修改的PUT提交方式
     * @param label
     * @param id
     * @return
     */
    @RequestMapping(value = "/{id}", method = RequestMethod.PUT)
    public Result update(@RequestBody Label label, @PathVariable String id) {
        label.setId(id);
        labelService.updateLabel(label);
        return new Result(true, StatusCode.OK, "修改成功", null);
    }

    /**
     * 根据id删除
     * @param id
     * @return
     */
    @RequestMapping(value = "/{id}", method = RequestMethod.DELETE)
    public Result deleteById(@PathVariable String id){
        labelService.delLabelById(id);
        return new Result(true, StatusCode.OK, "删除成功", null);
    }
}

（5）、公共异常处理类

BaseExceptionHandler.java

package com.scf.base.controller;

import entity.Result;
import entity.StatusCode;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;

/**
 * 公共异常处理类
 */
@ControllerAdvice
public class BaseExceptionHandler {

    @ResponseBody
    @ExceptionHandler(value = Exception.class)  //value对应的是要处理的异常类型
    public Result error(Exception e){
        e.printStackTrace();
        return new Result(false, StatusCode.ERROR, e.getMessage(), null);
    }
}

3、基础微服务的条件查询功能

（1）、LabelController.java

    /**
     * 带条件查询标签列表
     * @param searchMap
     * @return
     */
    @RequestMapping(value = "/search",method = RequestMethod.POST)
    public Result findSpecification(@RequestBody Map searchMap){
        List labelList = labelService.findLabelBySpecification(searchMap);
        return new Result(true, StatusCode.OK, "查询成功", labelList);
    }

（2）、LabelService.java

   /**
     * 带条件查询标签列表
     *
     * @param searchMap ：条件集合
     * @return
     */
    public List findLabelBySpecification(Map searchMap) {
        Specification specification = this.createSpec(searchMap);
        return labelDao.findAll(specification);
    }

    /**
     * 封装查询条件
     *
     * @param searchMap

    private Specification createSpec(Map searchMap) {
        return new Specification() {
            @Override
            public Predicate toPredicate(Root root, CriteriaQuery criteriaQuery, CriteriaBuilder cb) {

4、基础微服务的条件+分页查询功能

（1）、LabelController.java

    /**
     * 带条件的分页查询
     *
     * @param searchMap
     * @param page      当前页
     * @param size      每页显示条数
     * @return
     */
    @RequestMapping(value = "/search/{page}/{size}", method = RequestMethod.POST)
    public Result findByPage(@RequestBody Map searchMap, @PathVariable(name = "page") int page, @PathVariable int size) {
        Page pageList = labelService.findByPage(searchMap, page, size);
        PageResult pageResult = new PageResult(pageList.getTotalElements(), pageList.getContent());
        return new Result(true, StatusCode.OK, "查询成功", pageResult);
    }

（2）、LabelService.java

    /**
     * 带条件的分页查询方法
     * @param searchMap
     * @param page 当前页
     * @param size  每页显示条数
     * @return
     */
    public Page findByPage(Map searchMap, int page, int size) {
        Specification specification = this.createSpec(searchMap);
        PageRequest pageRequest = PageRequest.of(page - 1, size);
        return labelDao.findAll(specification, pageRequest);
    }
