AutoProtoSchemaBuilder未生成原型文件

Question

根据@Ryan Emerson的建议更新了我的代码，但我仍然没有看到任何自动生成的Impl文件和proto文件

@AutoProtoSchemaBuilder(
        includeClasses = { Book.class,  Author.class },
        schemaFileName = "library.proto",
        schemaFilePath = "proto/")
        interface DummyInitializer extends SerializationContextInitializer {


}

著者班

public class Author {
    private final String name;
    private final String surname;

    @ProtoFactory
    public Author(String name, String surname) {
        this.name = (String)Objects.requireNonNull(name);
        this.surname = (String)Objects.requireNonNull(surname);
    }

    @ProtoField(
        number = 1
    )
    public String getName() {
        return this.name;
    }

    @ProtoField(
        number = 2
    )
    public String getSurname() {
        return this.surname;
    }

    public boolean equals(Object o) {
        if (this == o) {
            return true;
        } else if (o != null && this.getClass() == o.getClass()) {
            Author author = (Author)o;
            return this.name.equals(author.name) && this.surname.equals(author.surname);
        } else {
            return false;
        }
    }

    public int hashCode() {
        return Objects.hash(new Object[]{this.name, this.surname});
    }
}

书班

public class Book {
    private final String title;
    private final String description;
    private final int publicationYear;
    private final Set<Author> authors;

    @ProtoFactory
    public Book(String title, String description, int publicationYear, Set<Author> authors) {
        this.title = (String)Objects.requireNonNull(title);
        this.description = (String)Objects.requireNonNull(description);
        this.publicationYear = publicationYear;
        this.authors = (Set)Objects.requireNonNull(authors);
    }

    @ProtoField(
        number = 1
    )
    public String getTitle() {
        return this.title;
    }

    @ProtoField(
        number = 2
    )
    public String getDescription() {
        return this.description;
    }

    @ProtoField(
        number = 3,
        defaultValue = "-1"
    )
    public int getPublicationYear() {
        return this.publicationYear;
    }

    @ProtoField(
        number = 4
    )
    public Set<Author> getAuthors() {
        return this.authors;
    }

    public boolean equals(Object o) {
        if (this == o) {
            return true;
        } else if (o != null && this.getClass() == o.getClass()) {
            Book book = (Book)o;
            return this.publicationYear == book.publicationYear && this.title.equals(book.title) && this.description.equals(book.description) && this.authors.equals(book.authors);
        } else {
            return false;
        }
    }

    public int hashCode() {
        return Objects.hash(new Object[]{this.title, this.description, this.publicationYear, this.authors});
    }
}

具有覆盖方法的上下文初始化器类

import org.infinispan.protostream.SerializationContext;

import java.io.UncheckedIOException;

public class contextInitializer implements DummyInitializer {
    @Override
    public String getProtoFileName() {
        return null;
    }

    @Override
    public String getProtoFile() throws UncheckedIOException {
        return null;
    }

    @Override
    public void registerSchema(SerializationContext serCtx) {

    }

    @Override
    public void registerMarshallers(SerializationContext serCtx) {

    }
}

然后实例化上下文初始化器的ClassA

public class classA {


  DummyInitializer myInterface= new contextInitializer();



    //Create a new cache instance


    public void startCache() {
        {

          try {
            manager = new DefaultCacheManager("src/main/resources/infinispan.xml");
            GlobalConfigurationBuilder builder= new GlobalConfigurationBuilder();
            builder.serialization().addContextInitializers(myInterface);
            System.out.println("------------------>"+ builder.serialization().addContextInitializers(myInterface));
            cache = manager.getCache();
            System.out.println(cache.getName()+" is initialized ");
          } catch (IOException e) {
            throw new IllegalArgumentException("Failed to initialize cache due to IO error",e);
          }
        }

        }

我仍然没有看到任何自动生成的原始文件。有人能告诉我我做错了什么吗？

Answer 1

您并不是说使用了哪个构建系统。也许是maven？是否将protostream注释处理器添加为依赖项？对这些问题有一个明确的答案将有助于解决代码生成的问题。之后，我们仍然需要找出谁应该初始化dummyInitializer字段。

Answer 2

您还需要添加org。英菲尼斯潘。protostream:protostream处理器工件作为依赖项，以便生成代码：

<dependency>
    <groupId>org.infinispan.protostream</groupId>
    <artifactId>protostream-processor</artifactId>
    <version>4.3.2.Final</version>
</dependency>

一旦出现，一个DummyInitializerImpl。将生成java类，该类自动注册书籍和作者类的原型文件和封送器。记住，为了生成模式和封送器，这些类还必须具有protostream注释。有关代码示例，请参阅文档。

当前代码存在两个问题：

1. 您提供了一个DummyInitializerImpl类，但这是@AutoProtoSchemaBuilder应该生成的
2. 在您的DummyInitializerImpl中，您正在尝试注册书籍和作者类型的InfinispanUUIDMarshaller。这不起作用，因为marshaller是为javaUUID类设计的

我怀疑这两个问题是由于对代码生成工作原理的错误理解。如果您只需要为作者和书籍类使用序列化上下文初始值设定项，则无需手动创建DummyInitializerImpl，而且您肯定不需要使用UUIDMarshaller。
