组装json
这样一个表
—————————————
name | value | parnet
a1 | xxx | null
a2 | xxx | null
a3 | xxx | null
b1 | yyy | a2
b2 | yyy | a2
b3 | yyy | a3
c1 | zzz | b3
c2 | zzzz | b3
c3 | zzzz | b3
大概就是这么个父子关系,想组成一个多级节点的json。有什么好办法吗?
自己写的把自己绕进去了。。。
接口开关怎么实现?
是这样的,我目前知道的系统接口有两种形式,一种是固定uri,用serviceName传参来确定调用的服务;第二种是通过不同uri来实现。
我现在的问题是,怎么去实现一个接口开关。以第一种接口服务为例,我维护了一个服务注册类,该类中只有一个map类型的变量,key是serviceName,value是服务类。服务类有serviceName和开关表示,以及remark注释信息。在spring初始化时,在application中存放服务注册类对象。通过拦截器来存放第一次访问的接口服务以及判断接口开关状态,开关通过页面或接口来控制。
现在问题是,拦截器中,拦截到关闭,我想要返回一个固定的result对象,要怎么来?拦截发在pre阶段,这里spring只会返回boolean类型,我在请求关闭关闭状态的服务就会被catch到异常
