我需要@NonNull/@Nullable在 Kotlin 生成的 Java 代码中禁用注释,因为某些注释适配器(代码生成器)无法正确处理某些带注释的字段

你知道怎么做吗?一些 Kotlin 注释或编译器指令

问题:科特林类:

open class TestModel(
    var test: ByteArray = ByteArray(0)

)

生成的java:

public class TestModel {
@org.jetbrains.annotations.NotNull()
private byte[] test;

@org.jetbrains.annotations.NotNull()
public final byte[] getTest() {
    return null;
}

public final void setTest(@org.jetbrains.annotations.NotNull()
byte[] p0) {
}

public TestModel(@org.jetbrains.annotations.NotNull()
byte[] test) {
    super();
}

public TestModel() {
    super();
}
}

我要删除:@org.jetbrains.annotations.NotNull()注释

You can't. The generated Java code tool shows what the Java code for a class looks like. As a result, it will include @Nullable and @NotNull; they're a core part of the language. They're there to handle null safety.

val x: String is the same as @NotNull public String x (needs initialization and semi-colons to be valid, but you get the idea). You can't remove them automatically from the compiled code, unless you write your own compiler (but that would be a real pain).

If you have problems because of the annotations, just use Java instead. The annotations don't get added there, and you won't have any problems. You'd need to mix the languages, but it's designed for it, so you should be fine.
