如何以编程方式加载Spring webflow流并获取其内容

import org.springframework.webflow.config.FlowDefinitionResource;
import org.springframework.webflow.config.FlowDefinitionResourceFactory;
import org.springframework.webflow.definition.FlowDefinition;
import org.springframework.webflow.definition.registry.FlowDefinitionRegistry;
import org.springframework.webflow.definition.registry.FlowDefinitionRegistryImpl;
import org.springframework.webflow.engine.Flow;

public class SpringWebFlowLoader {
    public static void main(String[] args) {
        // 创建流程注册表
        FlowDefinitionRegistry registry = new FlowDefinitionRegistryImpl();

        // 创建流程定义资源工厂
        FlowDefinitionResourceFactory resourceFactory = new FlowDefinitionResourceFactory();

        // 加载流程定义资源
        FlowDefinitionResource resource = resourceFactory.createFileResource("path/to/flow.xml");

        // 注册流程定义到注册表
        registry.registerFlowDefinition(resource);

        // 获取流程定义
        FlowDefinition flowDefinition = registry.getFlowDefinition("flowId");

        // 获取流程内容
        Flow flow = (Flow) flowDefinition;
        // 可以使用flow对象的方法获取流程的状态、转换和其他属性
    }
}
