springcloud 新增微服务

个人记录

记录公司微服务项目，模块添加的步骤

一  创建Module

选择maven

groupid和artifactid 参考 pom文件

<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>
        <!-- 父项目 -->
        <artifactId>kps.parent</artifactId>
        <!-- 父项目id -->
        <groupId>com.kps</groupId>
        <version>1.0</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>
 
    <!-- 项目id -->
    <artifactId>kps.appAPIScan</artifactId>
    <!-- 项目名 -->
    <name>kps.appAPIScan</name>
    <url>http://maven.apache.org</url>
    <properties>
        <imageName>apiscan:${project.version}</imageName>
    </properties>
 
 
    <dependencies>
        <dependency>
            <groupId>com.kps</groupId>
            <artifactId>kps.web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>
        <!--
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-netflix-eureka-client</artifactId>
        </dependency>
        -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-client</artifactId>
        </dependency>
 
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
 
    </dependencies>
 
    <!-- 打boot结构jar插件  -->
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <configuration>
                    <imageName>${imageName}</imageName>
                </configuration>
            </plugin>
        </plugins>
    </build>
 
</project>

二  增加启动应用

这里注意，要和controller文件夹同级

代码：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.context.annotation.ComponentScan;
 
@EnableEurekaClient // 配置本应用将使用服务注册和服务发现
@SpringBootApplication
@ComponentScan(basePackages={"com.kps"},lazyInit=true)
@ServletComponentScan(basePackages={"com.kps"})
public class AppAPIScanApp {
    public static void main( String[] args )
    {
        SpringApplication.run(AppAPIScanApp.class, args);
    }
}

PS：如果SpringApplication报错：cannot access org.springframework.core.env

那么把Module重新导入一下就好了。

三  增加配置文件

application.yml

spring:
   application:
       name: kps.appAPIScan
 
server:
   port: 9100
 
#Security authentication is enabled by default above springboot 1.5.x
management:
   security:
      enabled: false
 
 
eureka:
    client:
        serviceUrl:
           defaultZone: ${registry.url}
    instance:
          lease-expiration-duration-in-seconds: 60
          lease-renewal-interval-in-seconds: 30
          preferIpAddress: true
          instanceId: ${spring.cloud.client.ipAddress}:${server.port}

bootstrap.yml

spring:
    http:
        encoding:
            charset: UTF-8
            enabled: true
            force: true
    cloud:
        config:
            uri: http://${host:localhost}:9089
            name: config
            profile: ${active:dev}

四  修改zuul网管配置

application.yml

spring:
   profiles:
      active: ${active:dev}
   application:
      name: springCloud.zuul
   thymeleaf:
           prefix: classpath:/templates/
           suffix: .html
           mode: LEGACYHTML5
           encoding: UTF-8
           content-type: text/html
           cache: false
 
 
server:
   port: 9090
#   context-path: /zuul
 
#Security authentication is enabled by default above springboot 1.5.x
management:
   security:
      enabled: false
      
eureka:
   client:
      serviceUrl:
            defaultZone: ${registry.url}      
      registry-fetch-interval-seconds: 5 # 拉取服务注册信息间隔时间 (默认为30秒)
   instance:
          lease-expiration-duration-in-seconds: 60  # 注册中心超过这个时间没收到心跳，会视为无效节点(默认为90秒)
          lease-renewal-interval-in-seconds: 30  # 发送心跳间隔时间（默认30秒）
          preferIpAddress: true
          instanceId: ${spring.cloud.client.ipAddress}:${server.port}      
      
 
zuul:
  add-host-header: true #webui重定向  请求头host显示为网关的（eg:localhost:9090）而非webui的
  ignoredServices: '*' #禁用服务名路游
  sensitive-headers:   #传递头信息
  retryable: true  #负载均衡时，路游的服务重启时，可通过重试到其他相同服务
#  host:
#     socket-timeout-millis: 60000
#     connect-timeout-millis: 60000
  routes:
      sys:
         path: /sys/**
         serviceId: kps.webAPISYS
      common:
         path: /common/**
         serviceId: kps.webAPICommon
      po:
         path: /po/**
         serviceId: kps.webAPIPO
      wms:
         path: /wms/**
         serviceId: kps.webAPIWMS  
      eq:
         path: /eq/**
         serviceId: kps.webAPIEQ      
      kps:
         path: /kps/**
         serviceId: kps.webUI
      helka:
         path: /helka/**
         serviceId: kps.helka
      abc:
         path: /abc/**
         serviceId: kps.abc
      app:
        path: /app/**
        serviceId: kps.appAPIScan
 
 

其实只增加了

    app:
        path: /app/**
        serviceId: kps.appAPIScan

五  看一下config中心

如果需要feign接口，那么就需要配置config，

(这里我没有配置，因为不需要)

看一下 config-dev

 #registry url
registry:
   url: http://${host:localhost}:9088/eureka/
 
 
## DataSource
spring:
    datasource:
        url: ***

       hibernate:
          ddl-auto: none
       database: mysql
       show-sql: false
    resources:
       chain:
          strategy:
             content:

                paths: /**
 
    redis:
       host: ***
       database: 1
       pool:
          max-active: 20
          min-idle: 1
          max-idle: 1
          max-wait: 1
 
#druid connect pool
db:
  druid:
     url: ${spring.datasource.url}
     username: ${spring.datasource.username}
     password: ${spring.datasource.password}
     filters: stat,wall
     max-active: 60
     initial-size: 10
     max-wait: 60000
     min-idle: 10
     time-between-eviction-runs-millis: 600000
     min-evictable-idle-time-millis: 300000
     test-while-idle: true
     test-on-borrow: false
     test-on-return: false
     pool-prepared-statements: false
     max-open-prepared-statements: 20
 
#file
