微服务创建项目总结

首先是新建一个父工程(project)
空的maven项目
建完以后,删除src
配置pom.xml

	<parent>
        <groupId>org.springframework.bootgroupId>
        <artifactId>spring-boot-starter-parentartifactId>
        <version>2.2.4.RELEASEversion>
        <relativePath/> 
    parent>

1.注册中心
配置pom.xml

<dependencies>
        <dependency>
            <groupId>org.springframework.cloudgroupId>
            <artifactId>spring-cloud-starter-netflix-eureka-serverartifactId>
        dependency>
    dependencies>

配置application.yml

server:
  port: 10086
spring:
  application:
    name: leyou-registry
eureka:
  client:
    service-url:
      defaultZone: http://localhost:10086/eureka
    register-with-eureka: false
  server:
    enable-self-preservation: false
    eviction-interval-timer-in-ms: 10000

编写引导类

@SpringBootApplication
@EnableEurekaServer
public class LeyouRegistryApplication {

    public static void main(String[] args) {
        SpringApplication.run(LeyouRegistryApplication.class);
    }
}

2.网关
同样的

		<dependency>
            <groupId>org.springframework.cloudgroupId>
            <artifactId>spring-cloud-starter-netflix-eureka-clientartifactId>
        dependency>

        <dependency>
            <groupId>org.springframework.cloudgroupId>
            <artifactId>spring-cloud-starter-netflix-zuulartifactId>
        dependency>

server:
  port: 10010
spring:
  application:
    name: leyou-gateway
eureka:
  client:
    service-url:
      defaultZone: http://localhost:10086/eureka
    registry-fetch-interval-seconds: 5
zuul:
  prefix: /api
  routes:
    item-service: /item/** #路由到商品的微服务

@SpringBootApplication
@EnableDiscoveryClient
@EnableZuulProxy
public class LeyouGatewayApplication {
    public static void main(String[] args) {
        SpringApplication.run(LeyouGatewayApplication.class);
    }
}

3.项目
创建一个项目
引入依赖

<packaging>pompackaging>

用于聚合工程或传递依赖用的。
4.项目的interface
用于提供异常和对象类的
通用mapper依赖

		<dependency>
            <groupId>javax.persistencegroupId>
            <artifactId>persistence-apiartifactId>
            <version>1.0version>
        dependency>

写pojo实体类
5.项目的service

<dependency>
            <groupId>org.springframework.cloudgroupId>
            <artifactId>spring-cloud-starter-netflix-eureka-clientartifactId>
        dependency>

        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-webartifactId>
        dependency>

        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-jdbcartifactId>
        dependency>

        <dependency>
            <groupId>org.mybatis.spring.bootgroupId>
            <artifactId>mybatis-spring-boot-starterartifactId>
        dependency>

        <dependency>
            <groupId>tk.mybatisgroupId>
            <artifactId>mapper-spring-boot-starterartifactId>
        dependency>

        <dependency>
            <groupId>com.github.pagehelpergroupId>
            <artifactId>pagehelper-spring-boot-starterartifactId>
        dependency>

        <dependency>
            <groupId>com.leyou.itemgroupId>
            <artifactId>leyou-item-interfaceartifactId>
            <version>1.0.0-SNAPSHOTversion>
        dependency>

        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-testartifactId>
        dependency>

        <dependency>
            <groupId>org.springframework.bootgroupId>
            <artifactId>spring-boot-starter-actuatorartifactId>
        dependency>

        <dependency>
            <groupId>mysqlgroupId>
            <artifactId>mysql-connector-javaartifactId>
        dependency>

server:
  port: 8081
spring:
  application:
    name: item-service
  datasource:
    url: jdbc:mysql://localhost:3306/leyou?serverTimezone=UTC
    username: root
    password: 1024
    driver-class-name: com.mysql.jdbc.Driver
eureka:
  client:
    service-url:
      defaultZone: http://127.0.0.1:10086/eureka # EurekaServer地址
  instance:
    lease-expiration-duration-in-seconds: 5
    lease-renewal-interval-in-seconds: 15

mybatis:
  type-aliases-package: com.leyou.item.pojo

@SpringBootApplication
@EnableDiscoveryClient
@MapperScan("com.leyou.item.mapper")
public class LeyouItemApplication {
    public static void main(String[] args) {
        SpringApplication.run(LeyouItemApplication.class);
    }
}

然后就是业务了
6.common模板
用来写工具类的
