寻求适用于企业应用的Java开源XML数据验证业务规则引擎

我正在为企业应用寻找一款基于Java的开源业务规则引擎，用于XML数据验证。以下是简化后的示例XML：

<Employees>
    <Employee>
        <EmployeeId>1</EmployeeId>
        <FirstName>Dave</Firstname>
        <MiddleName>M</MiddleName>
        <LastName>Doe</LastName>
        <!--
            On this field validate:
            - Minimum base salaray is at least 50000
            - Maximum base salaray does not exceeds 100000          
        -->
        <BaseSalary>54000</BaseSalary>
        <!--
            On this field validate:
            - Maximum bonuses does not exceeds 10000            
        -->
        <Bonuses>2000</Bonuses>
        <!--
            On this field validate:
            - Maximum commission does not exceeds 50000         
        -->
        <Commission>4000</Commission>
        <!--
            On this field validate:
            - BaseSalary + Bonuses + Commission = TotalComp         
        -->
        <TotalComp>60000</TotalComp>
    </Employee>
    <Employee>
        <EmployeeId>2</EmployeeId>
        <FirstName>John</Firstname>
        <LastName>Smith</LastName>
        <!--
            On this field validate:
            - Minimum base salaray is at least 50000
            - Maximum base salaray does not exceeds 100000          
        -->
        <BaseSalary>60000</BaseSalary>
        <!--
            On this field validate:
            - Maximum bonuses does not exceeds 10000            
        -->
        <Bonuses>4000</Bonuses>
        <!-- Since Commission tag doesn't exists commission validation should not trigger -->
        <!--
            On this field validate:
            - BaseSalary + Bonuses + Commission = TotalComp         
        -->
        <TotalComp>64000</TotalComp>
    </Employee>
    <Employee>
        <EmployeeId>3</EmployeeId>
        <FirstName>Thomas</Firstname>
        <MiddleName>L</MiddleName>
        <LastName>Johnson</LastName>
        <!--
            On this field validate:
            - Minimum base salaray is at least 50000
            - Maximum base salaray does not exceeds 100000          
        -->
        <BaseSalary>60000</BaseSalary>
        <!--
            On this field validate:
            - Maximum bonuses does not exceeds 10000            
        -->
        <Bonuses>5000</Bonuses>
        <!--
            On this field validate:
            - Maximum commission does not exceeds 50000         
        -->
        <Commission>4000</Commission>
        <!--
            On this field validate:
            - BaseSalary + Bonuses + Commission = TotalComp         
        -->
        <TotalComp>69000</TotalComp>
    </Employee>
</Employees>

具体验证需求 #

• 规则触发依赖标签存在性：例如员工#2缺少Commission标签，则不执行与Commission相关的验证
• 单个XML标签可绑定多条验证规则
• 单条规则可同时验证多个XML字段
• 支持运行时动态增删规则
• 处理100MB至1GB的XML文件，禁止全量加载至内存
• 具备验证会话机制：验证后续员工时，规则可访问之前员工的数据及验证结果（如验证员工#3时能调用员工#1、#2的相关信息）

适配需求的开源引擎推荐 #

Drools

• 支持规则的动态增删改，运行时可直接调整规则库，无需重启应用
• 可结合SAX或StAX流式XML解析方式，逐节点处理大体积XML，避免内存溢出
• 规则可通过条件判断标签是否存在来触发对应逻辑，轻松实现单标签多规则、单规则多字段的验证配置
• 内置的KieSession可维护验证上下文，存储历史员工数据与验证结果，供后续规则访问调用

OpenRules

• 轻量级Java规则引擎，规则定义直观易懂，支持动态更新规则集合
• 配合流式XML解析组件，适合处理大体积XML文件的增量验证
• 可通过自定义规则上下文对象跟踪验证会话中的历史数据，满足跨员工的关联验证需求
• 能灵活配置规则与XML标签的绑定关系，实现基于标签存在性的规则触发逻辑
