java - 使用yangtools解析yang模块失败

Question

我使用 opendaylight.yangtools 来解析我的应用程序中的 Yang 模块文件，我只想获取一些信息，而不是实例化或使用它。

我将这个依赖项添加到我的 Maven pom.xml 中:

<!-- opendaylight Yangtools -->
<dependency>
    <groupId>org.opendaylight.yangtools</groupId>
    <artifactId>yang-parser-impl</artifactId>
    <version>1.2.0-SNAPSHOT</version>
    <type>jar</type>
</dependency>        
<dependency>
    <groupId>org.opendaylight.yangtools</groupId>
    <artifactId>yang-parser-api</artifactId>
    <version>1.2.0-SNAPSHOT</version>
    <type>jar</type>
</dependency>
<dependency>
    <groupId>org.opendaylight.yangtools</groupId>
    <artifactId>yang-model-api</artifactId>
    <version>1.2.0-SNAPSHOT</version>
    <type>jar</type>
</dependency>

然后我创建一个类来实现解析函数:

import java.io.File;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import java.util.Set;
import org.opendaylight.yangtools.yang.model.api.Module;
import org.opendaylight.yangtools.yang.model.api.SchemaContext;
import org.opendaylight.yangtools.yang.model.parser.api.YangSyntaxErrorException;
import org.opendaylight.yangtools.yang.model.repo.api.YangTextSchemaSource;
import org.opendaylight.yangtools.yang.parser.rfc6020.repo.YangStatementStreamSource;
import org.opendaylight.yangtools.yang.parser.spi.meta.ReactorException;
import org.opendaylight.yangtools.yang.parser.spi.source.StatementStreamSource;
import org.opendaylight.yangtools.yang.parser.stmt.reactor.CrossSourceStatementReactor;
import org.opendaylight.yangtools.yang.parser.stmt.rfc6020.YangInferencePipeline;
import org.opendaylight.yangtools.yang.parser.stmt.rfc6020.YangStatementSourceImpl;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class YangParser {

    private static final Logger LOGGER = LoggerFactory.getLogger(YangParser.class);

    public YangParser() {    
    }

    public void parseModule(String file) throws IOException, YangSyntaxErrorException {   
        LOGGER.debug("Parse Yang module from file : " + file);

        try {
            File yang_file = new File(file);
            CrossSourceStatementReactor.BuildAction reactor = YangInferencePipeline.RFC6020_REACTOR.newBuild();            
            reactor.addSource(YangStatementStreamSource.create(
                YangTextSchemaSource.forFile(yang_file)));

            SchemaContext schemaContext = reactor.buildEffective();            

            Set<Module> modules = schemaContext.getModules();
            for (Module m : modules) {
                LOGGER.debug("Add YANG module : " + m.getName());
                LOGGER.debug("Namespace : " + m.getNamespace().toString());
            }

        }
        catch (ReactorException e) {
            throw new IllegalStateException("Parsing Yang module failed, error : " + e.getMessage());
        }
    }
}

然后我在 POST API 的 Controller 中使用此函数来上传 yang 文件并解析它。当上传一个简单的 Yang 文件时:

// Contents of "acme-system.yang"
module acme-system {
 namespace "http://acme.example.com/system";
 prefix "acme";

 organization "ACME Inc.";
 contact "joe@acme.example.com";
 description
     "The module for entities implementing the ACME system.";

 revision 2007-06-09 {
     description "Initial revision.";
 }

 container system {
     leaf host-name {
         type string;
         description "Hostname for this system";
     }

     leaf-list domain-search {
         type string;
         description "List of domain names to search";
     }

     container login {
         leaf message {
             type string;
             description
                 "Message given at start of login session";
         }

         list user {
             key "name";
             leaf name {
                 type string;
             }
             leaf full-name {
                 type string;
             }
             leaf class {
                 type string;
             }
         }
     }
 }
}

我有一个成功的响应正文:

<name>acme-system</name>
<namespace>http://acme.example.com/system</namespace>
<description>The module for entities implementing the ACME system.</description>
<reference/>
<organization>ACME Inc.</organization>
<contact>joe@acme.example.com</contact>
<revision>1181340000000</revision>
<yangVersion>1</yangVersion>

当我上传定义了导入的 Yang 文件时，我的响应正文不成功，并出现以下错误:

Parsing Yang module failed, error : Some of SOURCE_PRE_LINKAGE modifiers for statements were not resolved.

这些是日志:

你能帮我吗？

谢谢。

Answer 1

我不是 100% 明白你在做什么，但我认为这条信息很关键:

Caused by: org.opendaylight.yangtools.yang.parser.spi.meta.InferenceException: Imported module [ietf-interfaces] was not found. [at /home/user/yang/iana-if-type.yang:5:2]

因此，您正在尝试加载 iana-if-type.yang，并且它具有对 ietf-interfaces.yang 的导入，但它无法解析。但我不是 100% 确定你必须做什么..

您是否已经尝试过在/home/user/yang/中简单地添加 ietf-interfaces.yang ？不确定是否有效/是否足够 - 您可能必须告诉 YANG 解析器 API 从哪里/如何加载依赖项。在 ODL 中的 RT 期间，这通过 CP 的 OSGi 进行。在 ODL 中的 CLI mvn 绑定(bind)生成期间，这是有效的，因为 Maven 插件会查看项目 CP 以查找依赖的 YANG 模型。事实上，如果你look around the source code of the yang-maven-plugin它如何找到依赖项，您可能可以从那里弄清楚？

HTH。否则，您也可以通过我们的https://lists.opendaylight.org/mailman/listinfo/yangtools-dev获得更多帮助。对于这样的事情。
