gradle7.6.1+springboot3.2.4創建微服務工程

一、創建主工程cloud-demo并刪除src目錄

二、創建子工程user-service/order-service?

三、更改父工程build.gradle文件?

四、子工程使用mybatis框架

?五、子工程使用mybatis-plus框架

六、相關數據庫創建

?七、最終目錄結構

一、創建主工程cloud-demo并刪除src目錄

二、創建子工程user-service/order-service?

三、更改父工程build.gradle文件?

?ext內容需配合設置云效倉庫參數到環境變量及gradle使用-CSDN博客使用?

plugins {  id 'org.springframework.boot' version '3.2.4'  id 'io.spring.dependency-management' version '1.1.4'  
}  group = 'com.fafa'  subprojects {  apply plugin: 'org.springframework.boot'  apply plugin: 'io.spring.dependency-management'  apply plugin: 'java'  sourceCompatibility = 17  targetCompatibility = 17  ext {  MAVEN_REPO_RELEASE_URL = System.getenv('MAVEN_REPO_RELEASE_URL')  MAVEN_REPO_SNAPSHOT_URL = System.getenv('MAVEN_REPO_SNAPSHOT_URL')  MAVEN_DEPLOY_USER = System.getenv('MAVEN_DEPLOY_USER')  MAVEN_DEPLOY_PASSWORD = System.getenv('MAVEN_DEPLOY_PASSWORD')  }  repositories {  maven { url "https://maven.aliyun.com/nexus/content/groups/public/" }  maven {  url 'https://maven.aliyun.com/repository/public'  }  maven { url "https://repo.spring.io/milestone" }  maven { url "https://plugins.gradle.org/m2/" }  maven {  credentials {  username MAVEN_DEPLOY_USER  password MAVEN_DEPLOY_PASSWORD  }  url MAVEN_REPO_RELEASE_URL  }  maven {  credentials {  username MAVEN_DEPLOY_USER  password MAVEN_DEPLOY_PASSWORD  }  url MAVEN_REPO_SNAPSHOT_URL  }  mavenCentral()  }  dependencies {  //Spring Boot Web 啟動器  implementation 'org.springframework.boot:spring-boot-starter-web'  compileOnly 'org.projectlombok:lombok'  runtimeOnly 'com.mysql:mysql-connector-j'  annotationProcessor 'org.projectlombok:lombok'  testImplementation 'org.springframework.boot:spring-boot-starter-test' }  test {  useJUnitPlatform()  }  sourceSets {  main {  resources {  srcDirs = ['src/main/resources']  }  }  }  tasks.withType(JavaCompile) {  options.encoding = "UTF-8"  doLast {  copy {  from sourceSets.main.resources  into "$buildDir/resources/main"  }  }  }  
}

四、子工程使用mybatis框架

build.gradle

group = 'com.fafa.order'  
version = '1.0'  
description = "order-service"  apply plugin: 'application'  dependencies {  implementation 'org.mybatis.spring.boot:mybatis-spring-boot-starter:3.0.3' 
}

application.yml?

server:  port: 8084  spring:  datasource:  url: jdbc:mysql://localhost:3306/db_order?useSSL=false&useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC  username: root  password: 123456  
mybatis:  mapper-locations: classpath:/mappers/**/*.xml  type-aliases-package: com.fafa.order.entity

OrderMapper.xml?

<?xml version="1.0" encoding="UTF-8" ?>  
<!DOCTYPE mapper  
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"  
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">  <mapper namespace="com.fafa.order.mapper.OrderMapper">  <resultMap type="Order" id="orderResult">  <result property="orderId" column="order_id"/>  <result property="orderName" column="order_name"/>  <result property="goodsId" column="goods_id"/>  <result property="summary" column="summary"/>  </resultMap>  <sql id="selectOrderVo">  select * from order_info  </sql>  <select id="getAll" parameterType="Order" resultMap="orderResult">  <include refid="selectOrderVo"/>  <where>  <if test="orderName != null ">and order_name like concat('%', #{orderName}, '%')</if>  </where>  order by order_id desc  </select>  
</mapper>

Order.java?

package com.fafa.order.entity;  
import lombok.Data;  @Data  
public class Order {  private int orderId;  private String orderName;  private int goodsId;  private int summary;  
}

OrderMapper.java?

package com.fafa.order.mapper;    
import com.fafa.order.entity.Order;  
import org.apache.ibatis.annotations.Mapper;   
import java.util.List;  @Mapper  
public interface OrderMapper {  public List<Order> getAll(Order order);  
}

IOrderService.java?

package com.fafa.order.service;  
import com.fafa.order.entity.Order;  
import java.util.List;  public interface IOrderService {  List<Order> getAll(Order order);  
}

OrderService.java?

package com.fafa.order.service;  
import com.fafa.order.entity.Order;  
import com.fafa.order.mapper.OrderMapper;  
import org.springframework.beans.factory.annotation.Autowired;  
import org.springframework.stereotype.Service;  
import java.util.List;  @Service  
public class OrderService implements IOrderService{  @Autowired  private OrderMapper orderMapper;  @Override  public List<Order> getAll(Order order) {  return orderMapper.getAll(order);  }  
}

OrderController.java?

package com.fafa.order.controller;  
import com.fafa.order.entity.Order;  
import com.fafa.order.service.IOrderService;  
import org.springframework.beans.factory.annotation.Autowired;  
import org.springframework.web.bind.annotation.GetMapping;  
import org.springframework.web.bind.annotation.RequestMapping;  
import org.springframework.web.bind.annotation.RestController;  import java.util.List;  @RestController  
@RequestMapping("/order")  
public class OrderController {  @Autowired  private IOrderService orderService;  @GetMapping("/getAll")  public List<Order> getAll(Order order) {  return orderService.getAll(null);  }  
}

OrderApplication.java?

package com.fafa.order;  
import org.springframework.boot.SpringApplication;  
import org.springframework.boot.autoconfigure.SpringBootApplication;  @SpringBootApplication  
public class OrderApplication {  public static void main(String[] args) {  SpringApplication.run(OrderApplication.class, args);  }  
}

OrderApplicationTests.java?

package com.fafa.order;  
import com.fafa.order.entity.Order;  
import com.fafa.order.service.IOrderService;  
import org.junit.jupiter.api.Test;  
import org.springframework.beans.factory.annotation.Autowired;  
import org.springframework.boot.test.context.SpringBootTest;  
import org.springframework.util.Assert;  
import java.util.List;  @SpringBootTest  
public class OrderApplicationTests {  @Autowired  private IOrderService orderService;  @Test  public void getAll(){  List<Order> list=orderService.getAll(null);  Assert.isTrue(list.isEmpty(),"有數據");  list.forEach(System.out::println);  }  
}

test.http

### getAll  
GET http://localhost:8084/order/getAll  
Accept: application/json

?五、子工程使用mybatis-plus框架

?參考文章：gradle7.6.1+springboot3.2.4+mybatis-plus搭建工程-CSDN博客

六、相關數據庫創建

create database db_order;  
use db_order;  SET NAMES utf8mb4;  
SET FOREIGN_KEY_CHECKS = 0;  -- ----------------------------  
-- Table structure for order_info  
-- ----------------------------  
DROP TABLE IF EXISTS `order_info`;  
CREATE TABLE `order_info` (  `order_id` bigint NOT NULL AUTO_INCREMENT COMMENT '訂單ID',  `order_name` varchar(100) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT NULL COMMENT '訂單名稱',  `goods_id` bigint NULL DEFAULT NULL COMMENT '商品ID',  `summary` bigint NULL DEFAULT NULL COMMENT '總額',  PRIMARY KEY (`order_id`) USING BTREE  
) ENGINE = InnoDB AUTO_INCREMENT = 1 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_general_ci COMMENT = '訂單信息' ROW_FORMAT = Dynamic;  SET FOREIGN_KEY_CHECKS = 1;

create database db_user;  
use db_user;  SET NAMES utf8mb4;  
SET FOREIGN_KEY_CHECKS = 0;  -- ----------------------------  
-- Table structure for user_info  
-- ----------------------------  
DROP TABLE IF EXISTS `user_info`;  
CREATE TABLE `user_info` (  `user_id` bigint NOT NULL AUTO_INCREMENT COMMENT '用戶ID',  `user_name` varchar(50) CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci NULL DEFAULT '' COMMENT '用戶名',  `sex` tinyint NULL DEFAULT 0 COMMENT '性別 0 未知 1女 2男',  PRIMARY KEY (`user_id`) USING BTREE  
) ENGINE = InnoDB AUTO_INCREMENT = 6 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_general_ci COMMENT = '用戶表' ROW_FORMAT = Dynamic;  SET FOREIGN_KEY_CHECKS = 1;

?七、最終目錄結構
