唯读---项目基础搭建

一、建立父工程

第一步

file-->new-->project

image

第二步

选择maven，不选择模板，点击next

image

输入 GroupId: com.wedo.parent ArtifactId:wedo 下一步

image

选择代码空间-->finish

修改pom.xml文件

            </plugin>
        </plugins>
    </build>
</project>

ps：这个因为是以前写过的项目的依赖，现在又拉过来用，可能fastDFS暂时用不到，这个项目用的华为云OBS存储，前一阵子参加华为云的比赛，给了一张2000元代金券，然后买了一年的ECS和OBS，都是低配，现在不确定代码写完之后跑不跑的起来:smile:

wedo的src文件夹可以删除了

二、搭建Eureka注册中心

右键点击wedo-->new-->module选择maven，不使用模板，下一步

image

修改GroupId以及ArtifactId如图所示，修改完成后点击下一步

image

Module name记得加上-，如图所示，之后点击完成

image

修改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>wedo</artifactId>
        <groupId>com.wedo.parent</groupId>
        <version>1.0.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.wedo.registry</groupId>
    <artifactId>wedo-registry</artifactId>
    <version>1.0.0-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
        </dependency>
    </dependencies>


</project>

然后配置springboot启动类和application.yml文件

WedoRegistryApplication.java

package com.wedo;

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

@SpringBootApplication
@EnableEurekaServer
public class WedoRegistryApplication {
    public static void main(String[] args) {
        SpringApplication.run(WedoRegistryApplication.class);
    }
}

application.yml

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

image

三、搭建zuul网关微服务

前三步和搭建Eureka(wedo-registry)一致，不过注意GroupId改成com.wedo.gateway，ArtifactId改为wedo-gateway，同时finish之前注意“-”问题

配置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>wedo</artifactId>
        <groupId>com.wedo.parent</groupId>
        <version>1.0.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.wedo.gateway</groupId>
    <artifactId>wedo-gateway</artifactId>
    <version>1.0.0-SNAPSHOT</version>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
        </dependency>
    </dependencies>

</project>

配置启动类和application.yml配置文件

image

WedoGatewayApplication.java

package com.wedo;


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

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

application.yml

server:
  port: 10010
spring:
  application:
    name: wedo-gateway
eureka:
  client:
    service-url:
      defaultZone: http://localhost:10086/eureka
    registry-fetch-interval-seconds: 5
zuul:
  prefix: /api
  routes:
    # book-service: /book/**
    # search-service: /search/**

在如图目录下新建WedoCorsConfiguration(解决跨域)

[图片上传失败...(image-9046d5-1601977147698)]

package com.wedo.gateway.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.cors.CorsConfiguration;
import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
import org.springframework.web.filter.CorsFilter;

@Configuration
public class WedoCorsConfiguration {
    @Bean
    public CorsFilter corsFilter() {

        // 初始cors配置对象
        CorsConfiguration corsConfiguration = new CorsConfiguration();
        // 允许的域,不要写*，否则cookie就无法使用了
        corsConfiguration.addAllowedOrigin("http://manage.wedo.com");
        corsConfiguration.addAllowedOrigin("http://www.wedo.com");
        corsConfiguration.addAllowedOrigin("http://localhost:8080");
        // 允许携带Cookie信息
        corsConfiguration.setAllowCredentials(true);
        // 允许的请求方式, * 代表允许所有请求方式s
        corsConfiguration.addAllowedMethod("*");
        // 允许的头信息, * 代表所有的请求方法
        corsConfiguration.addAllowedHeader("*");

        // 初始化cors配置源对象
        UrlBasedCorsConfigurationSource configurationSource = new UrlBasedCorsConfigurationSource();
        configurationSource.registerCorsConfiguration("/**",corsConfiguration);

        // 返回CorsFilter实例, 参数: cors配置源对象
        return new CorsFilter(configurationSource);
    }
}

注意：我的电脑上修改了host文件，cros这里面几个域名都是指向127.0.0.1的:smile:

四、项目启动

调出services界面

image

点击刚刚写好的两个微服务，运行，启动成功后，浏览器访问localhost:10086，可以看到网关微服务已经注册到注册中心了

image

看到这个即为成功
