1.新建父工程
2.点击File - settings - Build Tools - Maven ，这里的Maven路径选择自己本地的maven路径。
3.Editor - File Types，末尾加上“.idea;.iml;”，设置隐藏impl文件和.idea文件；
4.File - settings - Build - Complier - Java Complier ,需要将编译版本设置为1.8；
5.pom.xml加入依赖
4.0.0 com.elio.springcloud springcloudtest 1.0-SNAPSHOT UTF-8 4.12 1.18.10 1.2.17 5.1.47 1.1.16 1.3.0 org.apache.maven.plugins maven-project-info-reports-plugin 3.0.0 org.springframework.boot spring-boot-dependencies 2.2.2.RELEASE pom import org.springframework.cloud spring-cloud-dependencies Hoxton.SR1 pom import com.alibaba.cloud spring-cloud-alibaba-dependencies 2.1.0.RELEASE pom import mysql mysql-connector-java ${mysql.version} runtime com.alibaba druid ${druid.version} org.mybatis.spring.boot mybatis-spring-boot-starter ${mybatis.spring.boot.version} junit junit ${junit.version} log4j log4j ${log4j.version} org.springframework.boot spring-boot-maven-plugin true true
6.创建子工程
点击finish后，我们可以看到构建成功的子项目
7.添加商品服务提供者的pom.xml配置
springcloud com.sdltxjt 1.0-SNAPSHOT 4.0.0 springcloud-product-provider-8100 org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-actuator mysql mysql-connector-java com.alibaba druid org.mybatis.spring.boot mybatis-spring-boot-starter org.springframework.boot spring-boot-devtools org.projectlombok lombok org.springframework.boot spring-boot-maven-plugin true true
8.右键商品服务提供者项目的resources文件夹，新增application.yml配置文件，新增之后application.yml前面有个绿色的小叶子标识
server:
port: 8100 #端口号
spring:
application:
name: springcloud-product-provider-8100
datasource:
url: jdbc:mysql://192.168.9.202:18080/springcloud?serverTimezone=Asia/Shanghai&useUnicode=true&characterEncoding=utf-8&zeroDateTimeBehavior=convertToNull&useSSL=false&allowPublicKeyRetrieval=true
driverClassName: com.mysql.jdbc.Driver
username: root
password: 123***
mybatis:
mapper-locations: classpath:mapping/*mapper.xml # Mybatis 映射文件位置
type-aliases-package: com.sdltxjt.springcloud.entity # 表对应的实体类包
9.右键java文件夹新增，实体类Product，这将是我们接下来的product表对应的实体类
package com.sdltxjt.springcloud.entity;
import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;
@NoArgsConstructor
@AllArgsConstructor
@Setter
@Getter
public class Product {
private Long id; //自增id
private String name;// 产品名称
private int stock;// 库存
}
10.新增dao层接口ProductMapper
package com.sdltxjt.springcloud.dao;
import com.sdltxjt.springcloud.entity.Product ;
import org.apache.ibatis.annotations.Param;
import org.springframework.stereotype.Repository;
@Repository
public interface ProductMapper {
public Product selectById(@Param("id") Long id);
public int deleteById(@Param("id") Long id);
public int updateById(@Param("id") Long id, @Param("name") String name);
public int insertOne(Product product);
}
11.右键resources文件，新增mappingproduct_mapper.xml文件，这个是product表对应的sql文件，包含简单的增删改查
12.新增ProductService.java文件
package com.sdltxjt.springcloud.service;
import com.sdltxjt.springcloud.entity.Product;
import org.apache.ibatis.annotations.Param;
public interface ProductService {
public Product selectById(Long id);
public int deleteById(Long id);
public int updateById(Long id, String name);
public int insertOne(Product product);
}
13.新增ProductServiceImpl.java 类
package com.sdltxjt.springcloud.service.impl;
import com.sdltxjt.springcloud.dao.ProductMapper;
import com.sdltxjt.springcloud.entity.Product;
import com.sdltxjt.springcloud.service.ProductService;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
@Service
public class ProductServiceImpl implements ProductService {
@Resource
private ProductMapper productMapper;
@Override
public Product selectById(Long id) {
return productMapper.selectById(id);
}
@Override
public int deleteById(Long id) {
return productMapper.deleteById(id);
}
@Override
public int updateById(Long id, String name) {
return productMapper.updateById(id, name);
}
@Override
public int insertOne(Product product) {
return productMapper.insertOne(product);
}
}
14.新增Result.java
package com.sdltxjt.springcloud.dto;
import lombok.AllArgsConstructor;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;
@AllArgsConstructor
@NoArgsConstructor
@Setter
@Getter
public class Result {
private int code;
private String message;
private Object result;
}
15.新增ProductProviderController.java
package com.sdltxjt.springcloud.controller;
import com.sdltxjt.springcloud.dto.Result;
import com.sdltxjt.springcloud.entity.Product;
import com.sdltxjt.springcloud.service.ProductService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.web.bind.annotation.*;
import javax.annotation.Resource;
@RestController
@Slf4j
@RequestMapping("/")
public class ProductProviderController {
@Resource
private ProductService productService;
@GetMapping("product/provider/get/{id}")
public Result selectById(@PathVariable("id") Long id){
return new Result(200, "查询成功", productService.selectById(id));
}
@GetMapping("product/provider/delete/{id}")
public Result deleteById(@PathVariable("id") Long id){
return new Result(200, "删除成功", productService.deleteById(id));
}
@PostMapping("product/provider/update")
public Result updateById(@RequestBody Product product){
return new Result(200, "修改成功", productService.updateById(product.getId(), product.getName()));
}
@PutMapping( "product/provider/add")
public Result insertById(@RequestBody Product product){
return new Result(200, "修改成功", productService.insertOne(product));
}
}
16.右键java文件夹，新增主启动类ProductProvider8100
ProductProvider8100内容如下，加上@SpringBootApplication和MapperScan注解
package com.sdltxjt.springcloud;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@MapperScan("com.sdltxjt.springcloud.dao")
public class ProductProvider8100 {
public static void main(String[] args){
SpringApplication.run(ProductProvider8100.class, args);
}
}
17.创建表结构
DROP TABLE IF EXISTS `product`; CREATE TABLE `product` ( `id` bigint(20) NOT NULL AUTO_INCREMENT, `name` varchar(255) DEFAULT NULL, `stock` int(10) unsigned DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB DEFAULT CHARSET=latin1;
18.至此微服务的商品提供者我们已经创建成功，接下来就是测试该提供者了,启动类ProductProvider8100上右键Run
19.浏览器地址输入 http://localhost:8100/product/provider/get/1
