概述:
spring boot 2.0相对于之前的版本,变化还是很大的。首先对jdk的版本要求已经不能低于1.8,其次依赖的spring的版本也是最新版本5.0,并集成了功能强大的webflux等。
springcloud finchley 版本的升级也带来了全新组件:spring cloud function 和 spring cloud gateway ,前者致力于函数式编程模块的整合,后者则是网关netflix zuul 的替换组件。
1)需要的依赖:
<?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> <groupid>com.iyb</groupid> <artifactid>saturn</artifactid> <version>0.0.1-snapshot</version> <packaging>jar</packaging> <name>sc-saturn</name> <description>sc-saturn for spring boot</description> <parent> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-parent</artifactid> <version>2.0.1.release</version> </parent> <properties> <project.build.sourceencoding>utf-8</project.build.sourceencoding> <project.reporting.outputencoding>utf-8</project.reporting.outputencoding> <java.version>1.8</java.version> <mapper.version>3.4.0</mapper.version> <pagehelper.version>4.1.6</pagehelper.version> <fastjson.version>1.2.13</fastjson.version> <jackson.version>2.8.5</jackson.version> <druid.version>1.0.27</druid.version> <mysql.version>5.1.40</mysql.version> <commons-fileupload.version>1.3.1</commons-fileupload.version> </properties> <dependencies> <!--starter begin--> <!--spring cloud starter--> <dependency> <groupid>org.springframework.cloud</groupid> <artifactid>spring-cloud-starter-consul-discovery</artifactid> </dependency> <dependency> <groupid>org.springframework.cloud</groupid> <artifactid>spring-cloud-starter-config</artifactid> </dependency> <dependency> <groupid>org.springframework.cloud</groupid> <artifactid>spring-cloud-starter-openfeign</artifactid> </dependency> <dependency> <groupid>org.springframework.cloud</groupid> <artifactid>spring-cloud-starter-netflix-hystrix</artifactid> </dependency> <dependency> <groupid>org.springframework.cloud</groupid> <artifactid>spring-cloud-starter-netflix-zuul</artifactid> </dependency> <dependency> <groupid>org.springframework.cloud</groupid> <artifactid>spring-cloud-starter-netflix-ribbon</artifactid> </dependency> <dependency> <groupid>org.springframework.cloud</groupid> <artifactid>spring-cloud-starter-sleuth</artifactid> </dependency> <!--tomcat starter--> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-tomcat</artifactid> <scope>provided</scope> </dependency> <dependency> <groupid>org.apache.tomcat.embed</groupid> <artifactid>tomcat-embed-jasper</artifactid> <scope>compile</scope> </dependency> <!--actuator starter--> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-actuator</artifactid> </dependency> <!--spring boot starter--> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter</artifactid> </dependency> <!--spring starter--> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-jdbc</artifactid> </dependency> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-aop</artifactid> </dependency> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-data-redis</artifactid> </dependency> <dependency> <groupid>org.springframework.boot</groupid> <artifactid>spring-boot-starter-web</artifactid> </dependency> <!--fastjon--> <dependency> <groupid>com.alibaba</groupid> <artifactid>fastjson</artifactid> <version>${fastjson.version}</version> </dependency> <dependency> <groupid>io.github.openfeign</groupid> <artifactid>feign-gson</artifactid> <version>9.3.1</version> </dependency> <!--lombok--> <dependency> <groupid>org.projectlombok</groupid> <artifactid>lombok</artifactid> </dependency> <dependency> <groupid>log4j</groupid> <artifactid>log4j</artifactid> <version>1.2.17</version> </dependency> <dependency> <groupid>commons-beanutils</groupid> <artifactid>commons-beanutils</artifactid> </dependency> <dependency> <groupid>commons-collections</groupid> <artifactid>commons-collections</artifactid> </dependency> <dependency> <groupid>org.apache.commons</groupid> <artifactid>commons-lang3</artifactid> <version>3.4</version> </dependency> <dependency> <groupid>com.netflix.feign</groupid> <artifactid>feign-gson</artifactid> <version>8.15.1</version> </dependency> </dependencies> // spring cloud finchley.release <dependencymanagement> <dependencies> <dependency> <groupid>org.springframework.cloud</groupid> <artifactid>spring-cloud-dependencies</artifactid> <version>finchley.release</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencymanagement> </project>
需要注意的地方:
部分依赖做了改变:
旧版本 | finchley 版本 |
---|---|
spring-cloud-starter-eureka-client | spring-cloud-starter-netflix-eureka-client |
spring-cloud-starter-eureka-server | spring-cloud-starter-netflix-eureka-server |
spring-cloud-starter-hystrix | spring-cloud-starter-netflix-hystrix |
spring-cloud-starter-hystrix-dashboard | spring-cloud-starter-netflix-hystrix-dashboard |
spring-cloud-starter-ribbon | spring-cloud-starter-netflix-ribbon |
spring-cloud-starter-turbine | spring-cloud-starter-netflix-turbine |
spring-cloud-starter-zuul | spring-cloud-starter-netflix-zuul |
spring-cloud-starter-feign | spring-cloud-starter-openfeign |
新版本的 springcloud 上面的依赖都发生了变化,依赖中都引入了 netflix,或许是为了声明吧(组件的实现底层并非spring)。
log4j依赖:
在spring cloud之前的版本中,日志只需要引入lombok即可,但是finchley版本需要单独的引用。
<!--lombok--> <dependency> <groupid>org.projectlombok</groupid> <artifactid>lombok</artifactid> </dependency> <dependency> <groupid>log4j</groupid> <artifactid>log4j</artifactid> <version>1.2.17</version> </dependency>
2)集成consul配置文件:
spring: application: name: sc-saturn profiles: active: dev cloud: config: # uri: http://localhost:9999 discovery: enabled: false serviceid: sc-earth-config-server label: master profile: pre consul: host: http://localhost:8500 port: 80 discovery: prefer-ip-address: true #这里是重写健康检查的endpoint,默认为 /health,重写是为了节省不必要的网络传输,只需要http 200状态码即可 health-check-path: /ok/health heartbeat: enabled: false
3)启动类:
@springbootapplication @enablefeignclients @enablezuulserver @componentscan(basepackages={"com.iyb.ak"}) @enablediscoveryclient @slf4j public class saturnapplication implements commandlinerunner{ public static void main(string[] args) { springapplication.run(saturnapplication.class, args); } @override public void run(string... args) throws exception { log.info(">>>>>>>>>>>>>>> sc-saturn 启动完成<<<<<<<<<<<<<"); } }
4)示例:
注册中心:
可以看到 sc-saturn 已经成功注册到 consul中了。另外,上面的consul ui界面发生了变化,这是1.2版本做出的优化,相较以前的ui界面,已经好看很多了。
以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
