如何在Clojure中使Java类不可变？

public final class ImmutableJavaClass {
    private final String field1;
    private final int field2;

    public ImmutableJavaClass(String field1, int field2) {
        this.field1 = field1;
        this.field2 = field2;
    }

    public String getField1() {
        return field1;
    }

    public int getField2() {
        return field2;
    }
}

(ns my-namespace
  (:import [ImmutableJavaClass]))

(defn create-immutable-java-class [field1 field2]
  (ImmutableJavaClass. field1 field2))

(defn get-field1 [immutable-java-class]
  (.getField1 immutable-java-class))

(defn get-field2 [immutable-java-class]
  (.getField2 immutable-java-class))

(defrecord ImmutableClojureRecord [field1 field2])

(defn create-immutable-clojure-record [field1 field2]
  (->ImmutableClojureRecord field1 field2))

(defn get-field1 [immutable-clojure-record]
  (:field1 immutable-clojure-record))

(defn get-field2 [immutable-clojure-record]
  (:field2 immutable-clojure-record))
