netty学习八:在window上安装thrift以及第一个小demo

下载thrift window编译器

---

需要先下载编译器,本文用的版本是:

thrift-0.10.0.exe

对应的下载链接:thrift编译器

将下载好后的thrift-0.10.0.exe重命名成thrift.exe,并配置到window path路径上,假设thrift.exe是放置在如下目录:

D:\test\software\lib\thrift

那么直接将D:\test\software\lib\thrift配置到path上。

使用cmd命令打开一个窗口,执行:

thrift -version

正常情况下会输出thrift的版本号:

Thrift version 0.10.0

---

下载thrift java依赖包

---

<dependency>    <groupId>org.apache.thrift</groupId>    <artifactId>libthrift</artifactId>    <version>0.10.0</version></dependency>

使用maven命令下载即可,下载成功后会有四个依赖包:

libthrift-0.10.0.jarslf4j-api-1.7.12.jarhttpclient-4.4.1.jarhttpcore-4.4.1.jar

---

下载thrift eclipse 插件

---

直接使用Eclipse的MarketPlace找不到thrift support这个插件,得使用Eclipse的Install new software的方式。

点击Eclipse的install new software按钮,输入地址

http://thrift4eclipse.sourceforge.net/updatesite/

下载thrift support 插件,这个插件的高亮功能还是相当完备的,建议开发者安装。

---

编写thrift idl文件

---

编写animal.thrift

namespace java thrift.generatedtypedef i16 shorttypedef i32 inttypedef i64 longtypedef bool booleantypedef string Stringstruct Animal { 1: optional String username, 2: optional int age, 3: optional boolean married}exception DataException { 1: optional String message, 2: optional String callStack, 3: optional boolean date}service AnimalService {  Animal getAnimalByUsername(1: required String name) throws (1: DataException dataException),  void saveAnimal(1: required Animal animal) throws (1: DataException dataException)}

animal.thrift位于:

src/main/java/thrift

完整路径是:

src/main/java/thrift/animal.thrift

其中的

typedef i16 shorttypedef i32 inttypedef i64 longtypedef bool booleantypedef string String

是做类型定义,因为thrift默认的类型定义不太符合java程序员的使用习惯.

---

使用thrift编译器生成java类

---

执行命令:

thrift –gen java src/main/java/thrift/animal.thrift

注意是gen前面是两个-,不是一个- .

执行成功后会生成gen-java目录:

gen-java   thrift     generated       Animal.java       AnimalService.java       DataException.java

这些文件不是在java source目录下的,我们可以将其拷贝到source目录下,本文中将其拷贝到如下source目录:

thrift.generated

---

实现Animal业务层服务类

---

package thrift.firstdemo;import org.apache.thrift.TException;import thrift.generated.Animal;import thrift.generated.AnimalService;import thrift.generated.DataException;/** * 业务层服务类  * */public class AnimalBizService implements AnimalService.Iface{    @Override    public Animal getAnimalByUsername(String name) throws DataException, TException {        System.out.println("client name:"+name);        Animal animal = new Animal();        animal.setUsername(name);        animal.setAge(34);        animal.setMarried(true);        return animal;    }    @Override    public void saveAnimal(Animal animal) throws DataException, TException {        System.out.println("saveAnimal");        System.out.println(animal.getUsername());        System.out.println(animal.getAge());        System.out.println(animal.isMarried());    }}

通常用thrift生成service后,会用一个业务实现类来实现thrift servce接口,完成业务逻辑.

Thrift Server端代码

---

package thrift.firstdemo;import org.apache.thrift.TProcessorFactory;import org.apache.thrift.protocol.TCompactProtocol;import org.apache.thrift.server.THsHaServer;import org.apache.thrift.server.THsHaServer.Args;import org.apache.thrift.server.TServer;import org.apache.thrift.transport.TFramedTransport;import org.apache.thrift.transport.TNonblockingServerSocket;import org.apache.thrift.transport.TTransportException;import thrift.generated.AnimalService;public class ThriftServer {    public static void main(String[] args) throws TTransportException {        TNonblockingServerSocket socket = new TNonblockingServerSocket(8899);        Args arg = new THsHaServer.Args(socket).minWorkerThreads(2).maxWorkerThreads(4);        AnimalService.Processor<AnimalBizService> processors = new AnimalService.Processor<>(new AnimalBizService());        arg.protocolFactory(new TCompactProtocol.Factory());        arg.transportFactory(new TFramedTransport.Factory());        arg.processorFactory(new TProcessorFactory(processors));        TServer server = new THsHaServer(arg);        server.serve();    }}

---

Thrift Client端代码

---

package thrift.firstdemo;import org.apache.thrift.TException;import org.apache.thrift.protocol.TCompactProtocol;import org.apache.thrift.transport.TFramedTransport;import org.apache.thrift.transport.TSocket;import org.apache.thrift.transport.TTransport;import thrift.generated.Animal;import thrift.generated.AnimalService;import thrift.generated.AnimalService.Client;import thrift.generated.DataException;public class ThriftClient {    public static void main(String[] args) throws DataException, TException {        TTransport transport = new TFramedTransport(new TSocket("localhost", 8899),600);         TCompactProtocol tCompactProtocol = new TCompactProtocol(transport);        Client client = new AnimalService.Client(tCompactProtocol);        transport.open();        Animal animal = client.getAnimalByUsername("sam");        System.out.println(animal.getUsername());        System.out.println(animal.getAge());        System.out.println(animal.isMarried());        Animal animal2 = new Animal();        animal2.setUsername("sam2");        animal2.setAge(35);        animal2.setMarried(false);        client.saveAnimal(animal2);    }}

---

运行代码

---

分别运行ThriftServer类和ThriftClient类的main方法,启动服务端和客户端,正常情况下会打印如下日志:

client name:sam
saveAnimal
sam2
35
false

---

csdn code 路径

这个项目的源代码放置在csdn code上,欢迎访问。
