1.问题现象:

2.问题定位

3.问题解决

4.很少遇到JDK小版本导致出问题

1.问题现象:

使用langchain

      <!-- langchain4j start-->
      <dependency>
        <groupId>dev.langchain4j</groupId>
        <artifactId>langchain4j</artifactId>
        <version>${langchain4j.version}</version>
      </dependency>
      <dependency>
        <groupId>dev.langchain4j</groupId>
        <artifactId>langchain4j-open-ai-spring-boot-starter</artifactId>

java.lang.UnsatisfiedLinkError: no onnxruntime4j_jni in java.library.path

找不到

都是jdk1.8同样的windows别的同事电脑没问题。

2.问题定位

看日志错误代码在

AllMiniLmL6V2EmbeddingModel.class


    private static final OnnxBertBiEncoder MODEL = loadFromJar(
            "all-minilm-l6-v2.onnx",
            "bert-vocabulary-en.txt",
            PoolingMode.MEAN
    );


AbstractInProcessEmbeddingModel.class
    static OnnxBertBiEncoder loadFromJar(String modelFileName, String vocabularyFileName, PoolingMode poolingMode) {
        InputStream inputStream = AbstractInProcessEmbeddingModel.class.getResourceAsStream("/" + modelFileName);
        return new OnnxBertBiEncoder(
                inputStream,
                AbstractInProcessEmbeddingModel.class.getResource("/" + vocabularyFileName),
                poolingMode
        );
    }
