Spring Cloud Eureka简单入门

步骤：

1、创建父工程

2、创建EurekaServer工程

3、创建EurekaClient工程

父工程pom.xml

            <url>https://repo.spring.io/milestone</url>

</project>

创建EurekaServer module

1.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">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>com.spring</groupId>
        <artifactId>my_cloud</artifactId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <groupId>com.eureka</groupId>
    <artifactId>eureka-server</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>eureka-server</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <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>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>
    </dependencies>

</project>

2.配置启动类

package com.eureka.server;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;

@SpringBootApplication

@EnableEurekaServer

public class EurekaServerApplication {

    public static void main(String[] args) {

        SpringApplication.run(EurekaServerApplication.class, args);

    }

}

3.配置bootstrap.yml文件（没有自行创建），这里Eureka的配置使用了spring cloud config 配置中心进行了管理（具体配置文件在git上），所以这里直接引入配置即可

spring:

  application:

    name: eureka-server

  cloud:

    config:

      uri: http://127.0.0.1:9090

4.配置禁用Security默认开启的csrf校验

package com.eureka.server.util;

import org.springframework.security.config.annotation.web.builders.HttpSecurity;

import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;

import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

@EnableWebSecurity

public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override

    protected void configure(HttpSecurity http) throws Exception {

        super.configure(http);

        http.csrf().disable();

    }

}

创建EurekaClient工程

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">

    <modelVersion>4.0.0</modelVersion>

    <parent>

        <groupId>com.spring</groupId>

        <artifactId>my_cloud</artifactId>

        <version>1.0-SNAPSHOT</version>

    </parent>

    <groupId>com.eureka</groupId>

    <artifactId>eureka-provider</artifactId>

    <version>0.0.1-SNAPSHOT</version>

    <name>eureka-provider</name>

    <properties>

        <java.version>1.8</java.version>

    </properties>

    <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-config</artifactId>

        </dependency>

    </dependencies>

</project>

启动类配置：

package com.eureka.provider;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication

@EnableDiscoveryClient

public class EurekaProviderApplication {

    public static void main(String[] args) {

        SpringApplication.run(EurekaProviderApplication.class, args);

    }

}

3.配置bootstrap.yml文件（没有自行创建）

spring:

  cloud:

    config:

      uri: http://127.0.0.1:9090

      name: eureka-client

启动server和client即可查看结果
