在intellij中运行单元测试时的错误: java.lang.StackOverflowError
提问于 2019-06-05 13:27:18
我在一个基于狂妄自大的项目中有一套单元测试，每当我尝试从IDE中导入测试套件时，我都会得到下面的堆栈跟踪，说明发生了一个java.lang.StackOverflowError。

at de.hybris.bootstrap.config.ConfigUtil.expandProperty(ConfigUtil.java:603)这是de.hybris.bootstrap.config.ConfigUtil.expandProperty的代码
private static void expandProperty(String value, PlatformConfig platformConfig, Properties props, String key) {
String replacement = "";
int lastIndex = 0;
Pattern pattern = Pattern.compile("\\$\\{[^\\}]*\\}");
Matcher matcher = pattern.matcher(value);
for(String newKey = null; matcher.find(); lastIndex = matcher.end()) {
replacement = replacement + value.substring(lastIndex, matcher.start());
newKey = matcher.group().substring(2, matcher.group().length() - 1);
String newValue = platformConfig.getSystemConfig().getDir(newKey);
if (newValue == null) {
newValue = props.getProperty(newKey);
if (newValue != null && newValue.contains("${")) {
expandProperty(newValue, platformConfig, props, newKey);
newValue = props.getProperty(newKey);
}
}
if (newValue == null) {
replacement = replacement + matcher.group();
} else {
replacement = replacement + newValue;
}
}
if (lastIndex < value.length()) {
replacement = replacement + value.substring(lastIndex, value.length());
}
if (key != null) {
props.put(key, replacement);
}

如果您仔细查看您的功能的这一部分：
if (newValue == null) {
newValue = props.getProperty(newKey);
if (newValue != null && newValue.contains("${")) {
expandProperty(newValue, platformConfig, props, newKey);
newValue = props.getProperty(newKey);
}
}如果newValue == null为真，newValue != null && newValue.contains("${")为真，则
expandProperty(newValue, platformConfig, props, newKey); 将被执行，并再次使用相同的值调用expandProperty，再次执行expandProperty(newValue, platformConfig, props, newKey);，即生成对同一函数的无限调用，并触发expandProperty(newValue, platformConfig, props, newKey);异常。
希望这个好消息
