Overview
基于netty轻量的高性能分布式RPC服务框架。简单，易用，高效。
Features
- 服务端支持多种序列化方式：fastjson，hession，kryo
- 服务端支持多种压缩方式：gzip，snappy
- 服务端支持同时基于jersey暴露restful服务
- 支持注解配置，也支持spring xml配置
- 支持服务发现服务注册
- client端支持多种负载均衡策略和容灾策略
- client内置连接池
- client支持熔断，一个时间段错误次数达到一定阈值，自动熔断
- 基于netty 4.x版本实现，高性能（win 8cpu单机8w+）

Quick Start
Add dependencies to pom.
<dependency>
<groupId>com.zhizus</groupId>
<artifactId>forest-rpc</artifactId>
<version>0.0.2</version>
</dependency>
<dependency>
<groupId>com.zhizus</groupId>
<artifactId>forest-common</artifactId>
<version>0.0.2</version>
</dependency>
1.定义接口
通过注解
@ServiceProvider暴露服务，通过@MethodProvider暴露方法默认配置，如：压缩方式，序列化方式，客户端超时时间
@ServiceProvider(serviceName = "sampleService", haStrategyType = HaStrategyType.FAIL_FAST,
loadBalanceType = LoadBalanceType.RANDOM, connectionTimeout = Constants.CONNECTION_TIMEOUT)
public interface SampleService {
@MethodProvider(methodName = "say")
String say(String str);
@MethodProvider(methodName = "echo", serializeType = SerializeType.Hession2, compressType = CompressType.None)
String echo(String msg);
}
2.实现接口
基于注解
@ServiceExport发布服务，基于注解@MethodExport发布方法，
@Path("/sample")
@ServiceExport
public class SampleServiceImpl implements SampleService {
/**
* 支持jersey，可以通过配置打开，同时启动http服务
*
* @param str
* @return
*/
@Path("/hello/{str}")
@GET
@Produces("text/plain")
@MethodExport
@Rate(2)
@Override
public String say(@PathParam("str") String str) {
return "say " + str;
}
@Interceptor("metricInterceptor")
@MethodExport
@Override
public String echo(String msg) {
return "echo>>> " + msg;
}
}
3.服务端开发
spring context 配置：
application.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns="http://www.springframework.org/schema/beans" xmlns:forest="http://api.zhizus.com/schema/forest"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd
http://api.zhizus.com/schema/forest http://api.zhizus.com/schema/forest.xsd">
<context:component-scan base-package="com.zhizus.forest.demo"/>
<context:property-placeholder location="classpath:/*.properties"/>
<forest:registry id="registry" regProtocol="local" name="registry" address="127.0.0.1:2181"/>
<!--<forest:registry id="registry" regProtocol="zookeeper" name="registry" address="127.0.0.1:2181"/>-->
<forest:server id="forestServer" registry="registry" startHttpServer="true"/>
<forest:interceptors>
<forest:interceptor id="metricInterceptor" class="com.zhizus.forest.support.MetricInterceptor" auto-match="public *(*)"/>
</forest:interceptors>
</beans>
Server开发
public class SampleServer {
public static void main(String[] args) throws Exception {
new ClassPathXmlApplicationContext(new String[]{"application.xml"});
}
}
4.客户端开发
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns="http://www.springframework.org/schema/beans"
xmlns:aop="http://www.springframework.org/schema/aop" xmlns:forest="http://api.zhizus.com/schema/forest"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://api.zhizus.com/schema/forest http://api.zhizus.com/schema/forest.xsd">
<context:component-scan base-package="com.zhizus.forest.demo.client"/>
<forest:registry id="registry" regProtocol="local" name="registry" address="127.0.0.1:9999"/>
<forest:referer id="sampleService" interface="com.zhizus.forest.demo.api.SampleService" registry="registry">
<forest:method name="echo" timeout="5000" serializeType="Fastjson"/>
<forest:method name="say" timeout="5000" serializeType="Fastjson" compressType="GZIP"/>
</forest:referer>
</beans>
ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"application-client.xml"});
SampleService bean = (SampleService) context.getBean("sampleService");
String test = bean.say("hello");
Console输出
