没装Thrift的可以参照Mac上安装Thrift
本文参照：https://thrift.apache.org/tutorial/java
一、编写thrift文件,（其实就是thrift能识别的一种文档，根据此文档能生成各种语言版本的代码C++ JAVA 啥的）
1、shared.thrift

# Thrift Tutorial
# Mark Slee ([email protected])
#
# This file aims to teach you how to use Thrift, in a .thrift file. Neato. The
# first thing to notice is that .thrift files support standard shell comments.
# This lets you make your thrift file executable and include your Thrift build
# step on the top line. And you can place comments like this anywhere you like.
#
# Before running this file, you will need to have installed the thrift compiler
# into /usr/local/bin.
/**
* The first thing to know about are types. The available types in Thrift are:
*
* bool Boolean, one byte
* i8 (byte) Signed 8-bit integer
* i16 Signed 16-bit integer
* i32 Signed 32-bit integer
* i64 Signed 64-bit integer
* double 64-bit floating point value
* string String
* binary Blob (byte array)
* map<t1,t2> Map from one type to another
* list<t1> Ordered list of one type
* set<t1> Set of unique elements of one type
*
* Did you also notice that Thrift supports C style comments?
*/
// Just in case you were wondering... yes. We support simple C comments too.
/**
* Thrift files can reference other Thrift files to include common struct
* and service definitions. These are found using the current path, or by
* searching relative to any paths specified with the -I compiler flag.
*
* Included objects are accessed using the name of the .thrift file as a
* prefix. i.e. shared.SharedObject
*/
include "shared.thrift"
/**
* Thrift files can namespace, package, or prefix their output in various
* target languages.

* to look at. It even has pretty indentation.
*/二、用Thrift命令生成客户端和服务端模板代码
thrift -r --gen java tutorial.thrift
三、新建一个Idea Maven Project（这个不会就百度吧）
1、引入依赖
在pom.xml中引入依赖
<dependency>
<groupId>org.apache.thrift</groupId>
<artifactId>libthrift</artifactId>
<version>0.11.0</version>
</dependency>2、下载证书
https://github.com/apache/thrift/tree/master/lib/java/test
证书下载到本地的目录，客户端和服务端都要用的，这俩证书一个是公钥一个是私钥可以互换
3、客户端
新建一个名为"thrift-client" 的Module
复制二中shared和tutorial文件夹到src/main/java目录
新建一个”JavaClient“类
import tutorial.*;
import shared.*;
import org.apache.thrift.TException;
import org.apache.thrift.transport.TSSLTransportFactory;
import org.apache.thrift.transport.TTransport;
import org.apache.thrift.transport.TSocket;
import org.apache.thrift.transport.TSSLTransportFactory.TSSLTransportParameters;
import org.apache.thrift.protocol.TBinaryProtocol;
import org.apache.thrift.protocol.TProtocol;
/*
*功能：ThriftClient
*@author:zhangdaquan
*@date:2019/1/16 上午10:58
*@version:1.0
*/
public class JavaClient {
public static void main(String [] args) {
if (args.length != 1) {
System.out.println("Please enter 'simple' or 'secure'");
System.exit(0);
}
try {
TTransport transport;
if (args[0].contains("simple")) {
transport = new TSocket("localhost", 9090);
transport.open();
}
else {
/*
* Similar to the server, you can use the parameters to setup client parameters or
* use the default settings. On the client side, you will need a TrustStore which
* contains the trusted certificate along with the public key.
* For this example it's a self-signed cert.
*/
TSSLTransportParameters params = new TSSLTransportParameters();
params.setTrustStore("证书地址如：/home/truststore", "thrift", "SunX509", "JKS");
/*
* Get a client transport instead of a server transport. The connection is opened on
* invocation of the factory method, no need to specifically call open()
*/
transport = TSSLTransportFactory.getClientSocket("localhost", 9091, 0, params);
}
TProtocol protocol = new TBinaryProtocol(transport);
Calculator.Client client = new Calculator.Client(protocol);
perform(client);
transport.close();
} catch (TException x) {
x.printStackTrace();
}
}
private static void perform(Calculator.Client client) throws TException
{
client.ping();
System.out.println("ping()");
int sum = client.add(1,1);
System.out.println("1+1=" + sum);
Work work = new Work();
work.op = Operation.DIVIDE;
work.num1 = 1;
work.num2 = 0;
try {
int quotient = client.calculate(1, work);
System.out.println("Whoa we can divide by 0");
} catch (InvalidOperation io) {
System.out.println("Invalid operation: " + io.why);
}
work.op = Operation.SUBTRACT;
work.num1 = 15;
work.num2 = 10;
try {
int diff = client.calculate(1, work);
System.out.println("15-10=" + diff);
} catch (InvalidOperation io) {
System.out.println("Invalid operation: " + io.why);
}
SharedStruct log = client.getStruct(1);
System.out.println("Check log: " + log.value);
}
}4、服务端
新建一个名为"thrift-server" 的Module
复制二中shared和tutorial文件夹到src/main/java目录
新建一个”JavaServer“类
/*
*功能：
*@author:zhangdaquan

*/
import org.apache.thrift.server.TServer;
import org.apache.thrift.server.TServer.Args;

import org.apache.thrift.server.TThreadPoolServer;
import org.apache.thrift.transport.TSSLTransportFactory;
import org.apache.thrift.transport.TServerSocket;
import org.apache.thrift.transport.TServerTransport;
import org.apache.thrift.transport.TSSLTransportFactory.TSSLTransportParameters;
// Generated code
import tutorial.*;
import shared.*;
import java.util.HashMap;

public static CalculatorHandler handler;
public static Calculator.Processor processor;
public static void main(String [] args) {
try {

processor = new Calculator.Processor(handler);
Runnable simple = new Runnable() {
public void run() {
simple(processor);
}
};
Runnable secure = new Runnable() {
public void run() {
secure(processor);
}
};
new Thread(simple).start();
new Thread(secure).start();
} catch (Exception x) {
x.printStackTrace();
}
}
public static void simple(Calculator.Processor processor) {
try {
TServerTransport serverTransport = new TServerSocket(9090);
TServer server = new TSimpleServer(new Args(serverTransport).processor(processor));
// Use this for a multithreaded server
// TServer server = new TThreadPoolServer(new TThreadPoolServer.Args(serverTransport).processor(processor));
System.out.println("Starting the simple server...");
server.serve();
} catch (Exception e) {
e.printStackTrace();
}
}

try {
/*
* Use TSSLTransportParameters to setup the required SSL parameters. In this example
* we are setting the keystore and the keystore password. Other things like algorithms,
* cipher suites, client auth etc can be set.
*/
TSSLTransportParameters params = new TSSLTransportParameters();
// The Keystore contains the private key
params.setKeyStore("证书地址如：/User/keystore", "thrift", null, null);
/*
* Use any of the TSSLTransportFactory to get a server transport with the appropriate
* SSL configuration. You can use the default settings if properties are set in the command line.
* Ex: -Djavax.net.ssl.keyStore=.keystore and -Djavax.net.ssl.keyStorePassword=thrift
*
* Note: You need not explicitly call open(). The underlying server socket is bound on return
* from the factory class.
*/
TServerTransport serverTransport = TSSLTransportFactory.getServerSocket(9091, 0, null, params);
TServer server = new TSimpleServer(new Args(serverTransport).processor(processor));
// Use this for a multi threaded server
// TServer server = new TThreadPoolServer(new TThreadPoolServer.Args(serverTransport).processor(processor));
System.out.println("Starting the secure server...");
server.serve();
} catch (Exception e) {
e.printStackTrace();
}
}
}5、实现服务端具体业务功能（新建CalculatorHandler类实现Calculator.Iface接口）

}6、运行thrift-server
7、运行thrift-client，这里要再启动main函数的时候指定一个参数，如果是Idea的话参照Idea运行main函数传入参数
