一、Protocol
Google Protocol Buffer( 简称 Protobuf) 是 Google 公司内部的混合语言数据标准，目前已经正在使用的有超过 48,162 种报文格式定义和超过 12,183 个 .proto 文件。他们用于 RPC 系统和持续数据存储系统。
Protocol Buffers 是一种轻便高效的结构化数据存储格式，可以用于结构化数据串行化，或者说序列化。它很适合做数据存储或 RPC 数据交换格式。可用于通讯协议、数据存储等领域的语言无关、平台无关、可扩展的序列化结构数据格式。目前提供了 C++、Java、Python 三种语言的 API。
1、安装protobuf
[root@PCS102 src]# tar -zxvf protobuf-2.5.0.tar.gz -C /usr/local [root@PCS102 src]# ./configure && make && make check && make install [root@PCS102 protobuf-2.5.0]# whereis protoc protoc: /usr/local/bin/protoc [root@PCS102 protobuf-2.5.0]# /usr/local/bin/protoc --help Usage: /usr/local/bin/protoc [OPTION] PROTO_FILES Parse PROTO_FILES and generate output based on the options given: -IPATH, --proto_path=PATH Specify the directory in which to search for imports. May be specified multiple times; directories will be searched in order. If not given, the current working directory is used. --version Show version info and exit. -h, --help Show this text and exit. --encode=MESSAGE_TYPE Read a text-format message of the given type from standard input and write it in binary to standard output. The message type must be defined in PROTO_FILES or their imports. --decode=MESSAGE_TYPE Read a binary message of the given type from standard input and write it in text format to standard output. The message type must be defined in PROTO_FILES or their imports. --decode_raw Read an arbitrary protocol message from standard input and write the raw tag/value pairs in text format to standard output. No PROTO_FILES should be given when using this flag. -oFILE, Writes a FileDescriptorSet (a protocol buffer, --descriptor_set_out=FILE defined in descriptor.proto) containing all of the input files to FILE. --include_imports When using --descriptor_set_out, also include all dependencies of the input files in the set, so that the set is self-contained. --include_source_info When using --descriptor_set_out, do not strip SourceCodeInfo from the FileDescriptorProto. This results in vastly larger descriptors that include information about the original location of each decl in the source file as well as surrounding comments. --error_format=FORMAT Set the format in which to print errors. FORMAT may be 'gcc' (the default) or 'msvs' (Microsoft Visual Studio format). --plugin=EXECUTABLE Specifies a plugin executable to use. Normally, protoc searches the PATH for plugins, but you may specify additional executables not in the path using this flag. Additionally, EXECUTABLE may be of the form NAME=PATH, in which case the given plugin name is mapped to the given executable even if the executable's own name differs. --cpp_out=OUT_DIR Generate C++ header and source. --java_out=OUT_DIR Generate Java source file. --python_out=OUT_DIR Generate Python source file.
2、使用
(1)、编写 .proto 文件
文件命名规则：小写类名.proto，注意类名不要和内部的消息名相同
举例：phone.proto
package com.wjy.hbase; message PhoneDetail { required string dnum=1; required string length=2; required string type=3; required string date=4; } message dayPhoneDetail { repeated PhoneDetail dayPhoneDetail=1; }
注意：里面等号后面的值不要相同 否则不成功
(2)、编译.proto 文件
命令语法：
protoc -I=源文件目录 --java_out=生成文件目录 .proto文件
示例：
[root@PCS102 ~]# /usr/local/bin/protoc -I=/root --java_out=/root /root/phone.proto [root@PCS102 hbase]# pwd /root/com/wjy/hbase [root@PCS102 hbase]# ls Phone.java
