Question

在我的Android应用中，我使用了ConcurrentHashMap。只是一个get操作，然后叠加流程。

设备型号：NX511J Android操作系统：5.1.1 Android SDK：22

这是完整的堆栈跟踪：

java.lang.StackOverflowError: stack size 1036KB

(13000 same stack trace)

源代码（我认为它没有使用问题）：

private final ConcurrentMap<String, Module> immutableLocalCache = new ConcurrentHashMap<>();
    private Module getFromLocal(String moduleName) {
        Module module = immutableLocalCache.get(moduleName);// Stack over flow
        if (null != module) {
            return module;
        }
        //...
        try {
            Module ret = MinskDataConvertUtils.createMinskModule(data);
            immutableLocalCache.put(ret.name, ret);
            return ret;
        } catch (Exception e) {
            LogUtils.exception(e);
            return null;
        }
    }

Answer 1

堆栈溢出的常见原因是您在循环中传递的错误递归调用或条件。通常，这是在递归函数没有正确的终止条件时引起的，因此最终会自动调用它自己。

可能是您正在迭代或使用递归来获取操作。如果您正在使用循环检查您已经给出的条件。仍然存在错误，然后发布您的代码。

java.util.concurrent.ConcurrentHashMap.get（）抛出StackOverflowError
