把数组 JSON.stringify一下，java 用 @RequestBody String list 接收，然后用fastjson解析
header: { 'Content-type': 'application/json' } wx.request添加上面的header，参数一项直接填你的对象数组就OK了java的话用List<Object>接收吧，Object根据定义的对象来就可以了wx.request({method: 'POST',url: 'http:xxxx.xxx',data: [{a: '1',b: '2'},{a: '1',b: '2'}],header: {'Content-type': 'application/json'},success(res) {//},fail(err) {//}});直接在wx.request的data里写上就行了吧？
produceBzLzkAdd: this.data.allList
