目录

SpringCloud 智慧医疗整体项目结构说明：

smart-medical 项目创建

 smart-medical-common 通用模块创建

smart-medical-euraka-server 服务注册中心项目

smart-medical-provider 服务提供者服务

smart-medical-comsumer-ribbon 基于Ribbon 创建服务消费者

smart-medical-consumer-feign 基于Feign 服务消费者

smart-medical-zuul 网关服务

SpringCloud 智慧医疗整体项目结构说明：

smart-medical 项目创建

1、IDEA 创建smart-medical maven项目

2、依次创建子项目：

smart-medical-euraka-server
smart-medical-provider
smart-medical-comsumer-ribbon
smart-medical-common
smart-medical-consumer-feign
smart-medical-zuul

各个子模块的创建参考截图进行创建 

3、pom.xml 文件添加SpringBoot 版本和SpringCloud版本信息



    4.0.0
    
        org.springframework.boot
        spring-boot-starter-parent
        2.1.0.RELEASE
    



    
        smart-medical-euraka-server
        smart-medical-provider
        smart-medical-comsumer-ribbon
        smart-medical-common
        smart-medical-consumer-feign
        smart-medical-zuul
    


    org.example
    smart-medical
    1.0-SNAPSHOT
    pom

    
        1.8
        8
        8
        Greenwich.SR5
    

    
        
            
                org.springframework.cloud
                spring-cloud-dependencies
                ${spring-cloud.version}
                pom
                import
 smart-medical-common 通用模块创建

项目结构截图：

1、pom.xml 文件



    
        smart-medical
        org.example
        1.0-SNAPSHOT
    
    4.0.0

    smart-medical-common

    
        1.8
        8
        8

2、添加包名：com.zzg.model \com.zzg.service

package com.zzg.model;

import java.io.Serializable;
import java.util.Date;

public class User implements Serializable {
    private String id;

    private String account;

    private String name;

    private String passwd;

    private Date createDt;

    private String createBy;

    private Date updateDt;

    private String updateBy;

    private Byte state;

    private static final long serialVersionUID = 1L;

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id == null ? null : id.trim();
    }

    public String getAccount() {
        return account;
    }

    public void setAccount(String account) {
        this.account = account == null ? null : account.trim();
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name == null ? null : name.trim();
    }

    public String getPasswd() {
        return passwd;
    }

    public void setPasswd(String passwd) {
        this.passwd = passwd == null ? null : passwd.trim();
    }

    public Date getCreateDt() {
        return createDt;
    }

    public void setCreateDt(Date createDt) {
        this.createDt = createDt;
    }

    public String getCreateBy() {
        return createBy;
    }

    public void setCreateBy(String createBy) {
        this.createBy = createBy == null ? null : createBy.trim();
    }

    public Date getUpdateDt() {
        return updateDt;
    }

    public void setUpdateDt(Date updateDt) {
        this.updateDt = updateDt;
    }

    public String getUpdateBy() {
        return updateBy;
    }

    public void setUpdateBy(String updateBy) {
        this.updateBy = updateBy == null ? null : updateBy.trim();
    }

    public Byte getState() {
        return state;
    }

    public void setState(Byte state) {
        this.state = state;
    }

    @Override
    public String toString() {
        StringBuilder sb = new StringBuilder();
        sb.append(getClass().getSimpleName());
        sb.append(" [");
        sb.append("Hash = ").append(hashCode());
        sb.append(", id=").append(id);
        sb.append(", account=").append(account);
        sb.append(", name=").append(name);
        sb.append(", passwd=").append(passwd);
        sb.append(", createDt=").append(createDt);
        sb.append(", createBy=").append(createBy);
        sb.append(", updateDt=").append(updateDt);
        sb.append(", updateBy=").append(updateBy);
        sb.append(", state=").append(state);
        sb.append(", serialVersionUID=").append(serialVersionUID);
        sb.append("]");
        return sb.toString();
    }
}
package com.zzg.service;

import com.zzg.model.User;

import java.util.List;

public interface UserService {
    List selectAll();
}
smart-medical-euraka-server 服务注册中心项目

1、pom.xml 添加eurake 服务jar 包依赖



    
        smart-medical
        org.example
        1.0-SNAPSHOT
    
    4.0.0

    smart-medical-euraka-server

    
        1.8
        8
        8
    

    
    
        
            org.springframework.boot
            spring-boot-starter
        
        
        
            org.springframework.boot
            spring-boot-starter-test
        
        
        
            org.springframework.boot
            spring-boot-starter-web
        
        
        
            org.springframework.cloud
            spring-cloud-starter-netflix-eureka-server

 2、添加Eureka 服务注册中心的SpringBoot 程序入口。

package com.zzg;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication
@EnableEurekaServer
public class EurakaApplication {
    public static void main(String[] args) {
        SpringApplication.run(EurakaApplication.class, args);
    }
}

3、添加application.properties 配置文件

server.port=8081

# ???? ???????
eureka.instance.hostname=eureka-server

# eureka client ???????eureka client ??????
eureka.client.register-with-eureka=false
# ?????????eureka server ??eureka????
eureka.client.fetch-registry=false

#??????
eureka.server.enable-self-preservation=false
#??????????????????60??
eureka.server.eviction-interval-timer-in-ms=1000

eureka.client.serviceUrl.defaultZone=http://127.0.0.1:8081/eureka-server/
smart-medical-provider 服务提供者服务

项目截图：

1、pom.xml 添加eureka 客户端jar 、MyBatis、MySQL8、Alibaba Druid和智慧医疗通用项目模块依赖。



    
        smart-medical
        org.example
        1.0-SNAPSHOT
    
    4.0.0

    smart-medical-provider

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

package com.zzg.mapper;

import com.zzg.model.User;
import java.util.List;

public interface UserMapper {
    int deleteByPrimaryKey(String id);

    int insert(User record);

    User selectByPrimaryKey(String id);

    List selectAll();

    int updateByPrimaryKey(User record);
}



  
    
    
    
    
    
    
    
    
    
  
  
    delete from house_user
    where id = #{id,jdbcType=VARCHAR}
  
  
    insert into house_user (id, account, `name`, 
      passwd, create_dt, create_by, 
      update_dt, update_by, `state`
