在EasyRules 4.1.0中,您可以使用规则组CompositeRule来创建复合规则,将多个规则组合在一起,并在满足条件时执行统一操作。以下是一个示例:
```
public class MyObject {
private String name;
private int value;
// getters and setters
}
public class MyFirstRule implements Rule<MyObject> {
@Override
public boolean evaluate(MyObject myObject) {
// return true if the rule is satisfied
}
@Override
public void execute(MyObject myObject) throws Exception {
// execute the action when the rule is satisfied
}
}
public class MySecondRule implements Rule<MyObject> {
@Override
public boolean evaluate(MyObject myObject) {
// return true if the rule is satisfied
}
@Override
public void execute(MyObject myObject) throws Exception {
// execute the action when the rule is satisfied
}
}
CompositeRule compositeRule = new CompositeRule("My Composite Rule", "Composite rule that combines multiple rules", Rule.DEFAULT_PRIORITY);
compositeRule.addRule(new MyFirstRule());
compositeRule.addRule(new MySecondRule());
List<MyObject> myObjects = new ArrayList<>();
// populate myObjects with data
Rules rules = new Rules();
rules.register(compositeRule);
RulesEngine rulesEngine = new DefaultRulesEngine();
rulesEngine.fire(rules, myObjects);
```
在这个示例中,我们定义了两个规则`MyFirstRule`和`MySecondRule`,并将它们组合在一起,创建了一个名为"My Composite Rule"的复合规则`compositeRule`。我们还创建了一个`List<MyObject>`对象`myObjects`,其中包含多个`MyObject`对象,需要对其进行规则匹配和操作。最后,我们将`compositeRule`添加到`Rules`对象`rules`中,注册并执行`myObjects`上的所有规则。
当`myObjects`中的一个或多个对象满足`compositeRule`中的一个或多个规则时,将执行该复合规则中的所有规则的操作。
希望这次的回答可以解决您的问题。
