json-array参数

说明

• ~开头 : 系统要求的
• ~name : // 返回节点名称
• ~path : // 对应url的path
• !开头 : 固定参数不转换
• @开头 : 从jsonArray中el表达式中获得

• 开头 : 子集,嵌套调用。

• $开头 : 从结果集中el表达式中获得（如果是同步处理的话,注意数组顺序。异步不需要）
• 没有特殊字符开头的 : 别名用于转化结果集。

json-array

[{
  "!name" : "zhangsan",  
  "!sleep" : "2000",   
  "~name" : "hello1",  
  "~path" : "hello" 
},{
  "!sleep" : "1000",
  "$name" : "hello1",
  "~name" : "hello0",
  "~path" : "hello"
},{
  "!sleep" : "300",
  "!name" : "zhangsan2",
  "~name" : "hello2",
  "~path" : "hello"
}]

结果集:

 {"hello0":"zhangsan","hello1":"zhangsan","hello2":"zhangsan2"}

扩展

    /**
     * 从execAction中整理的内容,下放到子类具体实现。
     * @param path 路径.
     * @param argJson 参数.
     * @param alisJson 别名.
     * @param subJson 子集嵌套.
     * @return
     */
    public abstract Object execPath(String path , JSONObject argJson, JSONObject alisJson, JSONObject subJson){
        // 1.通过path找到对应的method.
        
        // 2. 把argJson、subJson转化成对应方法的入参.
        
        // 3. 执行方法
        
        // 4. 可选择性通过alisJson完成别名的转化。
        
        // 5. 返回结果值.
        return "";
    }
