【问题描述】：

habarta typescript generator 有问题，尝试了 2.7 的所有版本。到最新。这是 gradle 构建脚本

generateTypeScript {
    jsonLibrary = 'jackson2'
    classPatterns = [
        'com.foo.**'
    ]
    excludeClasses = [
        'org.springframework.data.mongodb.repository.ReactiveMongoRepository'
    ]
    excludeClassPatterns = [
        'java.io.Serializable',
        'com.foo.**Repository',
        'com.foo.**Builder',
        'org.springframework.data.mongodb.repository.**',
        'java.lang.Compareable',
        'org.bson.types.ObjectId'
    ]
    outputFile = 'build/customers.d.ts'
    outputKind = 'global'
    namespace = 'Customers'
    optionalProperties = 'all'
    customTypeMappings = [
        'java.time.LocalDateTime:string',
        'org.bson.types.ObjectId:string'
    ]
}

错误是

Unable to load class 'org.springframework.data.mongodb.repository.ReactiveMongoRepository'.

找不到的类在类路径中，编译项目工作正常。在 excludeClasses 或 excludeClassPatterns 中省略该类并没有什么不同。

应该转换的类（来自 classPatterns + excludeClasses(Patterns) 的规则）都没有实现 ReactiveMongoRepository。

我做错了什么以及如何解决这个问题？

【问题讨论】：

  • 你能发布整个 Gradle 构建文件和整个异常堆栈跟踪吗？
  • @LppEdd 确定，完成
  • 尝试在 excludeClassPatterns 属性下排除“ org.springframework.** ”。删除 excludeClasses 块。
  • 试过了，不幸的是同样的错误@LppEdd
  • 我会复制你的项目。

【解决方案1】：

所以，答案似乎是你有依赖于ReactiveMongoRepository 接口。

在不依赖 ReactiveMongoRepository 的情况下尝试您的项目设置，运行 generateTypeScript 会产生干净的构建。

但是，当依赖于该界面时，错误与您发布的内容相匹配（见下文）。 扩展 ReactiveMongoRepository 然后将其标记为已排除是行不通的，如果是这样的话，这有点无意义。

java.lang.NoClassDefFoundError: org/springframework/data/mongodb/repository/ReactiveMongoRepository
    at java.base/java.lang.ClassLoader.defineClass1(Native Method)
    at java.base/java.lang.ClassLoader.defineClass(ClassLoader.java:1016)
    ...

显然org.bson.types.ObjectId 不能被排除，因为您在UserData 中使用它。

要解决 Jackson 和 Bson 错误，您只需将它们作为依赖项。
到目前为止，它们只能通过传递依赖（transitive-dependency）获得，这可能是一个重新打包的版本。

compile group: 'com.fasterxml.jackson.datatype', name: 'jackson-datatype-jsr310', version: '2.9.8'
compile group: 'org.mongodb', name: 'bson', version: '3.10.1'

【讨论】：

  • 它似乎忽略了排除类模式中的所有内容。我发布了一个仅包含 ObjectId 的 mongo 文档，现在仅针对 ObjectId 出现相同的错误。请问可以试一试吗？
  • 我已经三次检查了对 ReactiveMongoRepository 的每个依赖项都在 excludeClassPatterns 中
  • 请注意，ObjectId 既在 excludeClassPatterns 中，也有自定义类型映射
  • PPS... :-) 删除 ObjectId 会导致有关 localDateTime 的错误。很奇怪
  • 在文档中看到了，是的。我目前正在检查更深入的内容，如果能恢复工作会很高兴，因为它很有帮助（并且已经在其他项目中工作过）
