Mycat 搭建springCloud

Mycat 搭建springCloud

先用maven 搭建父工程,在 引入springCloud依赖，spingboot依赖

  <dependencyManagement>
        <dependencies>

            <!--spring cloud 依赖-->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Greenwich.SR6</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

            <!--spring boot 项目依赖-->
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>2.1.10.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

            <dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
                <version>8.0.13</version>
            </dependency>

            <dependency>
                <groupId>com.github.pagehelper</groupId>
                <artifactId>pagehelper</artifactId>
                <version>5.1.10</version>
            </dependency>

            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <version>1.16.22</version>
            </dependency>


        </dependencies>
    </dependencyManagement>

再搭建你的子工程，要实现微服务，

先搭建微服务注册中心EUREKE

引入注册中心依赖

pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>mycatServiceSystem</artifactId>
        <groupId>org.example</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>mycat_eureka</artifactId>
    <dependencies>



          <!--注册中心eureka依赖-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
            <version>2.1.5.RELEASE</version>
        </dependency>
        <!--springboot web 依赖-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>



</project>

写配置文件 application.yml

spring:
  application:
    name: mycat_eureka_8001


server:
  port: 8001

eureka:
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://127.0.0.1:${server.port}/eureka/

  server:
    enable-self-preservation: true

编写运行EurekaApplication.java

package com;

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

/**
 * @program: distributeSystemDemo
 * @description:
 * @author: lxf
 * @create: 2021-09-14 23:20
 */
@EnableEurekaServer
@SpringBootApplication
public class EurekaApplication {

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

浏览器运行 http://localhost:8001/
