Springboot2.x整合eureka-server和netflix-zuul项目实战

Springboot2.x整合eureka-server和netflix-zuul项目实战，有啥问题欢迎提出优化。一起快乐的板砖。

微服务架构：

graph LR
A[whrm_gate] -- 访问 --> B(whrm_company)
A --  访问 --> C(whrm_system)
A -- 注册 -->D[whrm_eureka] 
B -- 注册 -->D
C -- 注册 -->D
E[用户] --> A

项目结构如下：

在这里插入图片描述

1、新建maven的父项目whrm

删除src文件，父项目不需要。
添加pom.xml文件内容如下:

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.12.RELEASE</version>
        <relativePath/>
    </parent>
     <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Hoxton.SR12</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-logging</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

2、新建maven子项目whrm_eureka

项目右键->New->Module... 根据流程下一步下一步新建就可以了。

在这里插入图片描述

代码目录如下：

在这里插入图片描述

pox.xml文件

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

    </dependencies>

新建application.properties

server.port=6868
spring.application.name=whrm_eureka

eureka.client.registerWithEureka=false
eureka.client.fetchRegistry=false
eureka.client.serviceUrl.defaultZone=http://127.0.0.1:${server.port}/eureka/

新建EurekaApplication.java

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


@EnableEurekaServer //开启Eureka服务端配置
@SpringBootApplication
public class EurekaApplication {
    public static void main(String[] args) {
        SpringApplication.run(EurekaApplication.class, args);
    }
}

新建ServletInitializer.java

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(EurekaApplication.class);
    }
}

到此，第一个子项目完成。

3、新建maven子项目whrm_gate

zuul网关项目

项目结构如下：

在这里插入图片描述

pom.xml文件

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>
        <!--eureka客户端-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
        <!--zuul网关-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
    </dependencies>

新建application.properties文件

server.port=9091
spring.application.name=whrm_gate

eureka.client.service-url.defaultZone=http://localhost:6868/eureka
#eureka.instance.ip-address=true
eureka.instance.prefer-ip-address=true
eureka.instance.instance-id=${spring.cloud.client.ip-address}:${spring.application.name}:${server.port}


# zuul 连接时间
zuul.host.connect-timeout-millis=60000
zuul.host.socket-timeout-millis=60000


zuul.routes.whrm-system.path=/sys/**
zuul.routes.whrm-system.serviceId=whrm-system
zuul.routes.whrm-system.stripPrefix=false
zuul.routes.whrm-system.sensitive-headers=true
zuul.routes.whrm-system.customSensitiveHeaders=true


zuul.routes.ihrm-company.path=/company/**
zuul.routes.ihrm-company.serviceId=whrm-company
zuul.routes.ihrm-company.stripPrefix=false
zuul.routes.ihrm-company.sensitive-headers=true
zuul.routes.ihrm-company.customSensitiveHeaders=true





hystrix.command.default.execution.timeout.enabled=true
hystrix.command.default.execution.isolation.thread.timeoutInMilliseconds=240000


ribbon.ReadTimeout=60000
ribbon.ConnectTimeout=60000
ribbon.MaxAutoRetries=0
ribbon.MaxAutoRetriesNextServer=1
ribbon.eureka.enabled=true

新建GateApplication.java

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
//开启zuul网关功能
@EnableZuulProxy
//开启服务发现功能
@EnableDiscoveryClient
public class GateApplication {
    public static void main(String[] args) {
        SpringApplication.run(GateApplication.class, args);
    }
}

新建ServletInitializer.java

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(GateApplication.class);
    }
}

到此，whrm_gate子项目完成。

4、新建maven子项目whrm_system

新建步骤同2

pom.xml

    <dependencies>
        <!--eureka -->
        <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-openfeign</artifactId>
        </dependency>
    </dependencies>

新建application.properties


server.port=9001
spring.application.name=whrm-system

#注册到eureka server
eureka.client.service-url.defaultZone=http://localhost:6868/eureka/
eureka.instance.preferIpAddress=true
eureka.instance.instance-id=${spring.cloud.client.ip-address}:${spring.application.name}:${server.port}

新建SystemApplication.java

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.openfeign.EnableFeignClients;

@SpringBootApplication
@EnableFeignClients
public class SystemApplication {
    public static void main(String[] args) {
        SpringApplication.run(SystemApplication.class, args);
    }
}

新建ServletInitializer.java

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(SystemApplication.class);
    }
}

新建 SystemController.java

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/sys")
public class SystemController {

    @RequestMapping("/hello")
    public String hello(){
        return "hello system controller!";
    }

}

5、新建maven子项目whrm_company

新建步骤同2

pom.xml

    <dependencies>
        <!--eureka -->
        <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-openfeign</artifactId>
        </dependency>
    </dependencies>

新建application.properties



server.port=9002
spring.application.name=whrm-company

#eureka server
eureka.client.service-url.defaultZone=http://localhost:6868/eureka/
eureka.instance.preferIpAddress=true
eureka.instance.instance-id=${spring.cloud.client.ip-address}:${spring.application.name}:${server.port}

新建CompanyApplication.java


import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.openfeign.EnableFeignClients;

@SpringBootApplication
@EnableFeignClients
public class CompanyApplication {
    public static void main(String[] args) {
        SpringApplication.run(CompanyApplication.class,args);
    }
}

新建ServletInitializer.java

import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

public class ServletInitializer extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
        return builder.sources(CompanyApplication.class);
    }
}

新建 CompanyController.java


import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/company")
public class CompanyController {

    @RequestMapping("/hello")
    public String hello(){
        return "hello CompanyController !";
    }
}

到此，whrm_company项目就创建完了。

完成，把每个微服务都运行起来！

访问http://127.0.0.1:6868/

显示以下页面就运行成功了！

在这里插入图片描述

就访问http://127.0.0.1:9091/sys/hello 正确显示hello system controller!
就访问http://127.0.0.1:9091/company/hello 正确显示hello CompanyController !

注： springboot 的版本一定要和spring-cloud-dependencies项目对应。不知道对应搜索就可以了。
