json数组解析成对象问题

{"Products":[{"years":"2006","proCode":"BYQ","throughput":"1","unit":"2","yield":"3","unit2":"4","totalHour"
:"5"},{"years":"2006","proCode":"","throughput":"11","unit":"22","yield":"33","unit2":"44","totalHour"
:"55"}],"Material":[{"years":"2006","matCode":"BYQ","consump":"111","unit":"222"}],"EnerConsu":[{"years"
:"2006","energyCode":"BYQ","consump":"1111","unit":"2222","useMaterial":"3333","unit2":"4444"}]}

请大神帮解析这个json然后封装到对象.一共是三个对象

c#解析json http://blog.csdn.net/chinacsharper/article/details/9246627

用阿里巴巴的fastjson jar包 配合GSON 一键完成。

这是用Gson解析的，实体楼在上面给你贴出来了，建议用GsonFormat插件直接生成实体类。
