在com.google.protobuf包中，我找到了Message接口(interface)，它声称它将按内容进行比较:
public interface Message extends MessageLite, MessageOrBuilder {
// -----------------------------------------------------------------
// Comparison and hashing
/**
* Compares the specified object with this message for equality. Returns
* <tt>true</tt> if the given object is a message of the same type (as
* defined by {@code getDescriptorForType()}) and has identical values for
* all of its fields. Subclasses must implement this; inheriting
* {@code Object.equals()} is incorrect.
*
* @param other object to be compared for equality with this message
* @return <tt>true</tt> if the specified object is equal to this message
*/
@Override
boolean equals(Object other);
但是我写测试代码:
public class Test {
public static void main(String args[]) {
UserMidMessage.UserMid.Builder aBuilder = UserMidMessage.UserMid.newBuilder();
aBuilder.setQuery("aaa");
aBuilder.setCateId("bbb");
aBuilder.setType(UserMidMessage.Type.BROWSE);
System.out.println(aBuilder.build() == aBuilder.build());
}
}
它给出
false。那么，如何与原型(prototype)缓冲区消息进行比较？
最佳答案

要使用您发布的代码，您必须将其与==进行比较
System.out.println(aBuilder.build().equals(aBuilder.build()));
