I. Thrift installation and Java code
1. build and install thrift
install boost
cd <boost_root>/tools/jam
./build_dist.sh
# linux* will depends the platform
cp stage/bin.linux*/bjam <boost_root>
# build boost, use bjam will faster
cd <boost_root>
./configure –without-icu –prefix=/usr/local/boost
./bjam -toolset=gcc –build-type=release install –prefix=/usr/local/boost
# build thrift
./bootstrap.sh
./configure –with-boost=/usr/local
make
make install
2. Build Thrift java library
install apache ant if necessary
cd lib/java/
ant
get libthrift.jar
3. Create .thrift file and gen Java code
(See http://wiki.apache.org/thrift/Tutorial for more .thrift tutorial info)
tim.thrift
struct dns_record {
1: string key,
2: string value,
3: string type = 'A',
4: i32 ttl = 86400,
5: string first,
6: string last
}
service TestDns {
dns_record test(1:string q);
}
<thrift_root>/bin/thrift –gen java tim.thrift
code will be generated in gen-java/*.java
4. Write java code
// new object dns_record dr = new dns_record(key, value, type, ttl, first, last) // serialize TSerializer serializer = new TSerializer(new TBinaryProtocol.Factory()); TDeserializer deserializer = new TDeserializer(new TBinaryProtocol.Factory()); byte[] bytes = serializer.serialize(dr);
see also: http://wiki.apache.org/thrift/ThriftUsageJava
II. Protocol Buffers install and Java code
1. Build and install Protocol buffers
./configure
make
make install
2. Build protobuf Java library
install maven if not necessary
cd protobuf/java
mvn test
mvn package
get jar from target/protobuf-java-x.x.x.jar
3. Create .proto file and gen Java code
tim.proto
package dns;
message DnsRecord {
required string key = 1;
required string value = 2;
required string first = 3;
required string last = 4;
optional string type = 5 [default = "A"];
optional int32 ttl = 6 [default = 86400];
}
message DnsResponse {
repeated DnsRecord records = 1;
}
bin/protoc –java_out . tim.proto
4. Write Java code
// protocol buffer need a builder to create object
Dns.DnsRecord.Builder b = Dns.DnsRecord.newBuilder();
b.setKey("key");
b.setValue("value...");
...
b.builder();
byte[] bytes = dr.toByteArray();
Dns.DnsRecord dr2 = Dns.DnsRecord.parseFrom(bytes);

[…] Thrift, Protocol Buffers installation and Java code howto […]
This is the perf testing vs thrift-0.30.0(with thrift_win32_compiler v0.30rc4) vs protobuf 2.3.0. By default, the protobuf is quite fast and compact in size, maybe the speed option is enabled by default?
This is the thrift, v0.30rc4
Thrift Loop : 1,000,000
Get object : 938msec
Serdes thrift : 6,578msec
Objs per second: 152,021
Total bytes : 113,000,000
This is the default protobuf without option optimize_for = SPEED;
ProtoBuf Loop : 1,000,000
Get object : 546msec
Serdes protobuf: 4,922msec
Objs per second: 203,169
Total bytes : 82,997,522

it was very usefull code thanks
