Easy Rules 4.0.0中如何创建复合规则类 且区分全匹配和部分匹配

在Easy Rules 4.0.0中，可以通过实现CompositeRule接口来创建复合规则类。CompositeRule接口继承了Rule接口，因此复合规则类也需要实现evaluate()方法，用于判断规则是否满足。同时，CompositeRule接口还提供了addRule()方法，用于添加子规则。

对于区分全匹配和部分匹配，可以在evaluate()方法中进行判断。具体实现方式可以根据具体需求来定，以下是一些示例代码：

public class FullMatchRule extends BasicRule {
    private String expected;

    public FullMatchRule(String name, String expected) {
        super(name);
        this.expected = expected;
    }

    @Override
    public boolean evaluate(Facts facts) {
        String actual = facts.get("input");
        return expected.equals(actual);
    }
}

public class PartialMatchRule extends BasicRule {
    private String expected;

    public PartialMatchRule(String name, String expected) {
        super(name);
        this.expected = expected;
    }

    @Override
    public boolean evaluate(Facts facts) {
        String actual = facts.get("input");
        return actual.contains(expected);
    }
}

public class CompositeRuleDemo implements CompositeRule {
    private String name;
    private List<Rule> rules = new ArrayList<>();

    public CompositeRuleDemo(String name) {
        this.name = name;
    }

    @Override
    public String getName() {
        return name;
    }

    @Override
    public boolean evaluate(Facts facts) {
        for (Rule rule : rules) {
            if (rule.evaluate(facts)) {
                return true;
            }
        }
        return false;
    }

    @Override
    public void addRule(Rule rule) {
        rules.add(rule);
    }
}

// Example usage
Facts facts = new Facts();
facts.put("input", "Hello, world!");

CompositeRuleDemo compositeRule = new CompositeRuleDemo("Composite Rule Demo");
compositeRule.addRule(new FullMatchRule("Full Match Rule", "Hello, world!"));
compositeRule.addRule(new PartialMatchRule("Partial Match Rule", "world"));

Rules rules = new Rules();
rules.register(compositeRule);

RulesEngine rulesEngine = new DefaultRulesEngine();
rulesEngine.fire(rules, facts);

在上面的示例代码中，FullMatchRule用于进行全匹配，PartialMatchRule用于进行部分匹配。CompositeRuleDemo是一个复合规则类，它包含了FullMatchRule和PartialMatchRule两个子规则。在evaluate()方法中，它会遍历所有子规则，并在其中找到满足条件的规则。如果有子规则满足条件，它就会返回true，表示整个复合规则也满足条件。如果所有子规则都不满足条件，它就会返回false。
