我試圖在Javascript中使用JSR223(https://github.com/openhab/openhab/wiki/Jsr223-Script-Engine)實現openHAB(http://www.openhab.org/)的規則。使用JSR223調用重載靜態方法時的異常
任何人有以下異常的根本原因的建議?注意兩個作爲參數傳遞的實例實現了在方法聲明中用作參數的接口。
java.lang.RuntimeException: java.lang.NoSuchMethodException: None of the fixed arity signatures [(org.openhab.core.items.Item, org.joda.time.base.AbstractInstant)] of method org.openhab.core.persistence.extensions.PersistenceExtensions.changedSince match the argument types [org.openhab.core.items.GroupItem, org.joda.time.DateTime]

以下是執行腳本:
'use strict';
load("nashorn:mozilla_compat.js");
importPackage(org.openhab.core.jsr223.internal.shared);
importPackage(org.joda.time);
importPackage(org.joda.time.base);
var autoOffRule = new org.openhab.core.jsr223.internal.shared.Rule() {
getEventTrigger: function() {
return [
new org.openhab.core.jsr223.internal.shared.TimerTrigger("* * * * * ?")
];
},
execute: function(event) {
for each(var item in ItemRegistry.getItems()) {
if (item.getState() == org.openhab.core.library.types.OnOffType.ON) {
var dateTime = org.joda.time.DateTime.now().withFieldAdded(DurationFieldType.seconds(), -5);
if (!(org.openhab.core.persistence.extensions.PersistenceExtensions.class.static.changedSince(item, var dateTime))) {
print("Auto-off for " + item.getName())
}
}
}
}
};
function getRules() {
return new org.openhab.core.jsr223.internal.shared.RuleSet([ autoOffRule ]);
}
被叫方法重載,具有以下特徵:
org.openhab.core.persistence.extensions.PersistenceExtensions#changedSince(org.openhab.core.items.Item, org.joda.time.base.AbstractInstant)
org.openhab.core.persistence.extensions.PersistenceExtensions#changedSince(org.openhab.core.items.Item, org.joda.time.base.AbstractInstant, java.lang.String)
測試和失敗上都jdk1.8.0_31和jdk1.8.0 _65。碰到Groovy中實施的規則或多或少的類似異常。
