LiteFlow推出了方法级别的声明特性。

方法级别式声明可以让用户在一个类中通过注解定义多个组件，更加的灵活。

如果你有非常多的组件，又同时想避免类的定义过多的问题，那这个特性非常适合这种需求。

你可以像这样来在一个bean里定义多个组件：

@LiteflowComponent
public class CmpConfig {

    //普通组件的定义
    @LiteflowMethod(value = LiteFlowMethodEnum.PROCESS, nodeId = "a", nodeName = "A组件", nodeType = NodeTypeEnum.COMMON)
    public void processA(NodeComponent bindCmp) {
        ...
    }

    //SWITCH组件的定义
    @LiteflowMethod(value = LiteFlowMethodEnum.PROCESS_SWITCH, nodeId = "b", nodeName = "B组件", nodeType = NodeTypeEnum.SWITCH)
    public String processB(NodeComponent bindCmp) {
        ...
    }
    
    //布尔组件的定义
    @LiteflowMethod(value = LiteFlowMethodEnum.PROCESS_BOOLEAN, nodeId = "c", nodeName = "C组件", nodeType = NodeTypeEnum.BOOLEAN)
    public boolean processC(NodeComponent bindCmp) {
        ...
    }
    
    //FOR组件的定义
    @LiteflowMethod(value = LiteFlowMethodEnum.PROCESS_FOR, nodeId = "d", nodeName = "D组件", nodeType = NodeTypeEnum.FOR)
    public int processD(NodeComponent bindCmp) {
        ...
    }
    
    //迭代组件的定义
    @LiteflowMethod(value = LiteFlowMethodEnum.PROCESS_ITERATOR, nodeId = "e", nodeName = "E组件", nodeType = NodeTypeEnum.ITERATOR)
    public Iterator<?> processE(NodeComponent bindCmp) {
        ...
    }
}

建议先阅读类级别式声明，再来阅读此章节。

如果你已经阅读，从上面的示例可以看到，这里和类级别声明组件相比，多了个nodeId参数。相同的组件的方法，都标识成一样的nodeId即可。其余的规则和类级别式声明一致。

以下是一个类里定义2个组件，每个组件定义3个方法的示例：

@LiteflowComponent
public class CmpConfig {

    @LiteflowMethod(value = LiteFlowMethodEnum.PROCESS, nodeId = "a", nodeType = NodeTypeEnum.COMMON)
    public void processA(NodeComponent bindCmp) {
        ...
    }

    @LiteflowMethod(value = LiteFlowMethodEnum.IS_ACCESS, nodeId = "a", nodeType = NodeTypeEnum.COMMON)
    public boolean isAccessA(NodeComponent bindCmp){
        ...
    }

    @LiteflowMethod(value = LiteFlowMethodEnum.ON_SUCCESS, nodeId = "a", nodeType = NodeTypeEnum.COMMON)
    public void onSuccessA(NodeComponent bindCmp){
        ...
    }

    @LiteflowMethod(value = LiteFlowMethodEnum.PROCESS_BOOLEAN, nodeId = "f", nodeType = NodeTypeEnum.BOOLEAN)
    public boolean processF(NodeComponent bindCmp) {
        ...
    }

    @LiteflowMethod(value = LiteFlowMethodEnum.IS_ACCESS, nodeId = "f", nodeType = NodeTypeEnum.BOOLEAN)
    public boolean isAccessF(NodeComponent bindCmp){
        ...
    }

    @LiteflowMethod(value = LiteFlowMethodEnum.ON_SUCCESS, nodeId = "f", nodeType = NodeTypeEnum.BOOLEAN)
    public void onSuccessF(NodeComponent bindCmp){
        ...
    }
}
