关于hibernate多对一对象转成json后传给extjs的store解析的问题0

hibernate取到的是many4对象 many4类和one4类是多对一关系,所以转成的json为[{"id":"8","name":"ee","one4":{"id":"4","name":"d"}},{"id":"6","name":"cc","one4":{"id":"1","name":"a"}},{"id":"4","name":"aa","one4":{"id":"1","name":"a"}},{"id":"5","name":"bb","one4":{"id":"2","name":"b"}},{"id":"7","name":"dd","one4":{"id":"3","name":"c"}},{"id":"9","name":"ff","one4":{"id":"3","name":"c"}}] 然后通过ajax给前台grid的store解析,我是这样构造model类的,many4的model为Ext.define("AM.model.Many4",{
    extend:"Ext.data.Model",
fields:[
{name:'id',type:'string'},
{name:'one4.id',type:'string'},
{name:'one4.name',type:'string'},
{name:'name',type:'string'}
]
});
但是问题来了 name在前台显示不出来,因为name在嵌套的层里也出现了一次,该怎么指定读取器只解析最外层的那个name？
然后我有时还需要后台传one4对象给前台显示,one4对象里有个many4的set集合,json是这样的[{"id":"3","many4s":[{"id":"9","name":"ff"},{"id":"7","name":"dd"}],"name":"c"},{"id":"1","many4s":[{"id":"6","name":"cc"},{"id":"4","name":"aa"}],"name":"a"},{"id":"2","many4s":[{"id":"5","name":"bb"}],"name":"b"},{"id":"1","many4s":[{"id":"6","name":"cc"},{"id":"4","name":"aa"}],"name":"a"},{"id":"4","many4s":[{"id":"8","name":"ee"}],"name":"d"},{"id":"3","many4s":[{"id":"9","name":"ff"},{"id":"7","name":"dd"}],"name":"c"},{"id":"5","many4s":[],"name":"f"}],然后我one4的model是这样Ext.define("AM.model.One4",{
    extend:"Ext.data.Model",
fields:[
{name:'id',type:'string'},
{name:'name',type:'string'},
{name:'many4s[0].name',type:'string'}
]
});
但是什么都显示不出来.我网上看到说配置belongTo,hasMany,我也试了下没成功，怎么配置extjs的关联关系来解析hibernate转换的json
