2.解压文件到：
D:\Java\protoc
将descriptor.proto生成java 代码，
D:\Java\protoc>protoc.exe -h
D:\Java\protoc>protoc.exe –java_out=./ D:\Java\protoc\protobuf-2.0.0beta\src\google\protobuf\descriptor.proto
3.在Eclipse中新建java工程
工程路径在：E:\lizongbo\workspace\protobuf
复制D:\Java\protoc下生成的com目录到E:\lizongbo\workspace\protobuf\src
复制D:\Java\protoc\protobuf-2.0.0beta\java\src\main\java下的com目录到E:\lizongbo\workspace\protobuf\src
4.定义一个proto文件
参考：http://code.google.com/apis/protocolbuffers/docs/proto.html
qquser.txt内容如下：
option java_package = “com.lizongbo.beans”;
option java_outer_classname = “QQUserProtos”;
message QQUser {
required int32 uin = 1 [default = 10000];
required string nick = 2 [default = "n"];
required int32 age = 3 [default = 20];
required int32 faceId = 4 [default = 0];
}
5.生成java代码：protoc.exe –java_out=./ qquser.txt
6.测试代码：
package com.lizongbo.beans;
public class Test {
/**
* @param args
*/
public static void main(String[] args) {
QQUserProtos.QQUser.Builder builder = QQUserProtos.QQUser.newBuilder();
builder.setAge(30);
builder.setFaceId(2);
builder.setNick(”lizongbo”);
builder.setUin(10000);
QQUserProtos.QQUser user = builder.build();
System.out.println(user.toString());
System.out.println(user.toByteString().toStringUtf8());
}
}
7.例子可以使用了。

Exception in the line of the Class:Test
QQUserProtos.QQUser user = builder.build();
请大虾告诉下是不是哪里设置错了？
