Question

List<Map<String,Object>中不同的值合并后转化为List<Map<String,Object>>

我想把[{appNo:'123',appName:'test1',appId:'abcde',platformName:'iOS'},
{appNo:'123',appName:'test1',appId:'12345',platformName:'android'},
{appNo:'456',appName:'test2',appId:'fghjk',platformName:'iOS'},
{appNo:'456',appName:'test2',appId:'67890',platformName:'android'}]这种结构转化为[{appNo:'123',appName:'test1',platform:[{appId:'abcde',platformName:'iOS'},{appId:'12345',platform:'android'}]},{appNo:'456',appName:'test2',platform:[{appId:'fghjk',platformName:'iOS'},{appId:'67890',platform:'android'}]}]这中结构java代码如何实现，谢谢！
