我发现在 catch 之后应该有一个 finally 块,但我不知道在 finally 块中添加什么。 或者还有其他解决方案吗?
当您创建变量 activationCOnfigParser 时,您处于 try/Catch 块中。 您可以绕过此错误:
private void getGtcj(String gtcjStatusValue, String strArchiveReqd) throws Exception {
XPathHelper activationConfigParser = null;
try {
activationConfigParser = ConfigUtil.getInstance().getConfigParser(new URL((V21Constants.FILE
+ System.getProperty(V21Constants.USER_DIR) + "/vServe21/config/ActivationParameters.xml")));
} catch (Exception e) {
actionConfigParser = <DEFAULT VALUE>
log.error(e.getMessage());
}
在 catch 块中,您可以替换为 actionConfigParser 在出现异常时必须假设的值。
