jprotobuf's Issues

增加对jprotobuf动态生成的类文件的生成

该功能可以支持把jprotobuf动态生成的中间代码的类文件输出到指定目录，以方便后续只有jre环境使用jprotobuf的可行性。

使用示例：Codec codec = ProtobufProxy.create(AddressBookProtosPOJO.class, false, new File("D:/"));

会在d盘根目录下生成中间的类文件对象。下次只需要把这个类文件对象加入到classpath中，就不会再执行动态编译过程了

java.lang.IllegalStateException: Failed to compile class, cause: Truncated class file, class: XXX$$JProtoBufClass, code: XXX

v1.7.5
最近一次发布版本才出现的.

ProtobufIDLGenerator对List类型生成问题

String idl = ProtobufIDLGenerator.getIDL(RequrieRepeatedNumberTypePOJOClass2.class);
System.out.println(idl);

输出错误内容如下
package com.baidu.bjf.remoting.protobuf.simplerepeat;
option java_outer_classname = "RequrieRepeatedNumberTypePOJOClass2$$ByJProtobuf";
message RequrieRepeatedNumberTypePOJOClass2 {
optional int32 list1=1;
}

public class RequrieRepeatedNumberTypePOJOClass2 {

@Protobuf(fieldType = FieldType.INT32, order = 1, required = false)
public List<Integer> list1;

}

由.proto文件生成pojo对引用嵌套enum支持有问题

jprotobuf版本：1.9.4

执行

ProtobufIDLProxy.generateSource(protoFile, srcPath);

抛异常：

Exception in thread "main" java.lang.RuntimeException: Message 'DataStatus' depend on message 'DataInfo.DataVisibility' is missed
    at com.baidu.bjf.remoting.protobuf.ProtobufIDLProxy.hasDependency(ProtobufIDLProxy.java:513)
    at com.baidu.bjf.remoting.protobuf.ProtobufIDLProxy.createClass(ProtobufIDLProxy.java:419)

proto：

message DataInfo {
    enum DataVisibility {
    PUBLIC = 1;
    PRIVATE = 2;
    }
...
}

message DataStatus {
    optional DataInfo.DataVisibility visibility = 1;
}

什么时候会正式发布2.X版本

使用@Protobuf方式，动态编译的POJO序列化反序列化效率非常低

版本1.9.8，使用@protobuf方式，序列化反序列化对象效率非常低。

在代码中调用API生成了POJO源代码（非预编译，是动态编译）
Codec simpleListCodec = ProtobufProxy.create(SimpleList.class, true);

发现生成的代码存在重复动态生成jprotobuf POJO源代码

public byte[] encode(SimpleList t) throws IOException {
    int size = 0;List f_2=null;
    if (!CodedConstant.isNull(t.getList())) {
        f_2=t.getList();
    }if (!CodedConstant.isNull(t.getList())){
        size += CodedConstant.computeListSize(2,f_2, FieldType.STRING,true,ProtobufProxy.OUTPUT_PATH.get());
    }
    if (f_2== null) {
        throw new UninitializedMessageException(CodedConstant.asList("list"));
    }
    final byte[] result = new byte[size];
    final CodedOutputStream output = CodedOutputStream.newInstance(result);
    writeTo(t, output);
    return result;
}

com.baidu.bjf.remoting.protobuf.CodedConstant#computeSize(int, java.lang.Object, com.baidu.bjf.remoting.protobuf.FieldType, boolean, boolean, java.io.File)

public static int computeSize(int order, Object o, FieldType type, boolean list, boolean debug, File path) {
        int size = 0;
        if (o == null) {
            return size;
        }
        if (type == FieldType.OBJECT) {
            Class cls = o.getClass();
            Codec target = ProtobufProxy.create(cls, debug, path);
            try {
                size = target.size(o);
                size = size + CodedOutputStream.computeRawVarint32Size(size);
                return size + CodedOutputStream.computeTagSize(order);
            } catch (IOException e) {
                throw new RuntimeException(e.getMessage(), e);
            }
        }
        if (type == FieldType.STRING) {
            size = CodedOutputStream.computeStringSizeNoTag(String.valueOf(o));
        } else if (type == FieldType.BOOL) {
            size = CodedOutputStream.computeBoolSizeNoTag(Boolean.valueOf(String.valueOf(o)));
        } else if (type == FieldType.BYTES) {
            byte[] bb = (byte[]) o;
            size = CodedOutputStream.computeBytesSizeNoTag(ByteString.copyFrom(bb));
        } else if (type == FieldType.DOUBLE) {
            size = CodedOutputStream.computeDoubleSizeNoTag(Double.valueOf(o.toString()));
        } else if (type == FieldType.FIXED32 || type == FieldType.INT32 || type == FieldType.SFIXED32
                || type == FieldType.SINT32 || type == FieldType.UINT32) {
            size = CodedOutputStream.computeInt32SizeNoTag(Integer.valueOf(o.toString()));
        } else if (type == FieldType.FIXED64 || type == FieldType.INT64 || type == FieldType.SFIXED64
                || type == FieldType.SINT64 || type == FieldType.UINT64) {
            size = CodedOutputStream.computeInt64SizeNoTag(Long.valueOf(o.toString()));
        } else if (type == FieldType.FLOAT) {
            size = CodedOutputStream.computeFloatSizeNoTag(Float.valueOf(o.toString()));
        } else if (type == FieldType.ENUM) {
            if (o instanceof EnumReadable) {
                size = CodedOutputStream.computeInt32SizeNoTag(((EnumReadable) o).value());
            } else if (o instanceof Enum) {
                size = CodedOutputStream.computeInt32SizeNoTag(((Enum) o).ordinal());
            }
        }

        return size;
    }

ProtobufProxy.create是没有缓存生成的对象的，每次调用都重新生成。

IDLGen.getIDL的问题

public class Test
{
@protobuf(fieldType = FieldType.INT32, order = 1, required = false)
private List list;
}

使用IDLGen.getIDL(Test.class);生成的描述文件不对:

message Test{
optional string list=1;
}
应该是repeated啊。。。

增加从注解的POJO类生成.proto描述文件

由于开发中使用注解方便了protobuf的开发，但目前这个功能仅对于java，如果要把注释开发功能，导出给其它语言使用，就需要单独编写.proto文件，需要额外的工作，所以加上自动生成.proto文件的功能可以简化这一部分工作

List<Integer>类型不支持

定义如下：
@protobuf
private List intList;

报错如下：
Class must has default constructor method with no parameters.

原始类型的数组或者list不支持？

Jprotobuf could not work on resin web app server

Dynamic compile failed on current class loader

增加对jprotobuf 复合类型数据用法

该特征将支持：
public class AddressBookProtosPOJO {

@Protobuf(fieldType = FieldType.OBJECT, order=1, required = false)
public PersonPOJO list;

/* (non-Javadoc)
 * @see java.lang.Object#toString()
 */
@Override
public String toString() {
    return "AddressBookProtosPOJO [list=" + list + "]";
}

}

public class PersonPOJO {

/* (non-Javadoc)
 * @see java.lang.Object#toString()
 */
@Override
public String toString() {
    return "PersonPOJO [name=" + name + ", id=" + id + ", email=" + email + "]";
}
@Protobuf(fieldType = FieldType.STRING, order=1, required = true)
public String name;
@Protobuf(fieldType = FieldType.INT32, order=2, required = true)
public int id;
@Protobuf(fieldType = FieldType.STRING, order=3, required = false)
public String email;

@Protobuf(fieldType = FieldType.DOUBLE, order=4, required = false)
public Double doubleF;


@Protobuf(fieldType = FieldType.FLOAT, order=5, required = false)
public Float floatF;

@Protobuf(fieldType = FieldType.BYTES, order=6, required = false)
public byte[] bytesF;

@Protobuf(fieldType=FieldType.BOOL, order=7, required=false)
public Boolean boolF;

}

Gradle怎么使用预编译插件？

改进建议

@protobuf(fieldType = FieldType.STRING, order = 1, required = true)
private String name;

@protobuf(fieldType = FieldType.INT32, order = 2, required = false)
private int value;

这些都可以用使用的默认值吧，
如String => STRING, int => INT32, long => INT64
默认required = false, order按bean的field顺序
这样别人就不需要写这么多东西了

BigDecimal类型的对象，是不是不支持？ from Karl <[email protected]>

ProtobufIDLGenerator是否可以提供一个重载的getIDL(Class<?> cls)方法？

ProtobufIDLGenerator目前只有getIDL(Class cls)一个public方法，我们还是需要一个这样的方法： getIDL(Class cls,Set<Class> cachedTypes,Set> cachedEnumTypes) 因为有这个方法的话，就可以避免重复生成同一个类的idl；比如A类引用了B类，C类也引用了B类，当生成A的idl后其实已经生成了B的idl，再调用getIDL(Class cls)传入C的时候，又一次生成B，所以把两个cache作为参数传入还是有意义的。我目前是在我们的项目里修改这个ProtobufIDLGenerator并提供这个getIDL(Class cls,Set<Class> cachedTypes,Set> cachedEnumTypes) 方法的。

关于属性默认值的问题

好像如果属性配置了默认值，生成后的Class类没有配置这个值

optional string Language = 6 [default = "en-US"];

原生的会有这个配置

private java.lang.Object language_ = "en-US";

序列化List<String>的时候报错，求解

请问为什么基本类型就报错了

不支持Map吗

不兼容的类型: java.util.List无法转换为java.util.ArrayList<

jprotobuf map支持问题

com.baidu jprotobuf 2.0.1-SNAPSHOT 这个支持map的版本的jar哪个maven仓库有？

怎么支持类似List<String> List<Integer> 的类型？

怎么支持类似List List 的类型字段？

ProtobufIDLGenerator的bug

举个例子：
public class Test
{
@protobuf
private List bps;

public List getBps()
{
return bps;
}
public void setBps(List bps)
{
this.bps = bps;
}
}

这个类，调用ProtobufIDLGenerator的getIDL(Test.class,new HashSet<Class>(),new HashSet>(),true);
生成如下idl：

message Test
{
repeated String bps=1;
}
message String {
}

应该生成这样的吧：
message Test
{
repeated string bps=1;
}

Jprotobuf增加对枚举类型的支持

@protobuf 注释支持枚举类型的支持
ProtobufIDLGenerator 支持枚举类型的idl生成
ProtobufIDLProxy支持包含枚举类型的idl动态代理支持，但目前不支持包含内部类与内部枚举类型方式

增加对android设备的支持

jprotobuf-android支持 android设备

com.baidu jprotobuf-android 1.1.1

默认值会被encode

一个类有10个字段,如果只使用了其中1个字段,其他9个字段 "应该" 不会encode.

增加由.proto 描述文件动态生成Protobuf操作对象的支持

支持直接根据.proto描述文件动态生成protobuf操作对象，这样可以极简化google protobuf的使用，同时针对需要动态根据.proto描述文件进行操作的实现也是非常有用的帮助

不好意思，问题解决了，请关闭Issues

@Protobuf的order属性是否应该为必选？

在协议定义时，字段顺序通常是明确的，使用默认值时如果不小心在中间新加了一个字段，就会造成协议不兼容，是否可以考虑设置必选？

另外，是否可以考虑order不定义的话，忽略该字段？

使用primitive类型属性且没有指定getter方法时，会导致编译失败

演示代码如下：

public class TestError {
      private int age;
}

java.lang.ExceptionInInitializerError

单独的测试方法中没有问题

    public static void main(String[] args) {
        Codec<UserJProtoBufProtoClass> codec = ProtobufProxy.create(UserJProtoBufProtoClass.class);
        System.out.println(codec);
    }

但如果在servlet 方法中调用就会抱这个错误

proto文件依赖另一个proto文件，生成POJO的时候会报错

使用1.7.4 Jprotobuf
测试新功能通过 .proto文件生成POJO类
发现如果 proto文件依赖另一个proto文件，生成带注解的POJO类时就会报错
例如：
package com.base.research;

option java_package = "com.base.research.protobufMsg.test";
option java_outer_classname = "AddressBookProto";

import "person.proto";

message AddressBook {
repeated Person person = 1;
}

是不支持吗？

由.proto 生成注解的POJO类

一般通信协议前后端使用的proto文件,服务器能直接通过proto生成带注解的POJO吗

List<String>这种可以支持吗？

如题，这种应该对应那种fieldType？

computeListSize 计算错误

public static int computeListSize(int order, List list, FieldType type) {
int size = 0;
if (list == null) {
return size;
}
for (Object object : list) {
size += computeSize(order, object, type, true);
}
if (type != FieldType.OBJECT) {
size += list.size();
}
return size;
}

.......

if (type != FieldType.OBJECT) {
//这里不能直接 += list.size ,因为只有 order < 16 的时候，tag占位才是1，
//应该是 += (list.size * CodedOutputStream.computeTagSize(order))
size += (list.size * CodedOutputStream.computeTagSize(order));
}

将测试用例中 List< String > 字段的 order 改为 >= 16 即可重现

OutputStream out = resp.getOutputStream();
codec.writeTo(obj, CodedOutputStream.newInstance(out));

返回的数据是空的

但调用客户端是可以得到返回值的

OutputStream out = resp.getOutputStream();    
out.write(codec.encode(obj));

是不是codec.writeTo 方法有问题？

JProtobuf-1.5.5 版本release

修正ProtobufIDLProxy动态解析多个类中含有相同名称的内置类会出现强制转换的异常问题

错误处理

要定义一套错误处理，比如我定义一个范型的rpcresponse 对象。

@Data
@NoArgsConstructor
@AllArgsConstructor
@EqualsAndHashCode(callSuper = false)
public class RPCResponse<T> {

  @Protobuf(required = true)
  private int status = RPCResponseUtil.OK_STATUS; // similar to httpStatus

  @Protobuf
  private T data;

  @Protobuf
  private Exception exception;

}

其范型T 的对象可以是

@Data
public class EchoInfo {

  @Protobuf
  public String message;
}

public class EchoRPCServiceImpl {
  @ProtobufRPCService(serviceName = "echoRPCService", methodName = "echo")
  public RPCResponse<EchoInfo> doEcho(String message) {
    RPCResponse<EchoInfo> ret = new RPCResponse();

    if (message.equals("hello")) {
      throw new UnknownException();
    }

    if (message.equals("jersey")) {
      throw new CustomException();
    }

    EchoInfo data = new EchoInfo();
    data.setMessage(message);
    ret.setData(data);
    return ret;
  }
}

public interface EchoRPCService {
  @ProtobufRPC(serviceName = "echoRPCService", onceTalkTimeout = 5000)
  RPCResponse<EchoInfo> echo(String message);
}

@Data
@NoArgsConstructor
@AllArgsConstructor
@EqualsAndHashCode(callSuper = false)
public class Exception {
  @Protobuf(required = true)
  private long timestamp;

  @Protobuf
  private int status;

  @Protobuf(required = true)
  private String errorCode;

  @Protobuf(required = true)
  private String errorMessage;

  @Protobuf(required = true)
  private String exception;

  @Protobuf
  private String path;
}

这样处理了，好像总是报错。
目前不支持范型？
或者有没有更好的方式处理错误呢？我目前知道的是用继承的方式，一个个属性写在基类里面。
