android+rxjava+gson 出错，大神帮忙看下。

[WMERP]

本人新手刚自学java和安卓，现在自己摸索 SYBASE数据库+JAX-RS 和 android + retrofit + rxjava + gson : 现在总是在POST抛出异常，用CURL测试都是成功更新数据库，证明服务器端没有问题。

Android测试页面按钮代码如下（GET可以正常运行）

ls_ent.setchnname("测试公式");
ls_ent.setengname("tstddd");
Gson jsonObject =new Gson();
jsonObject.toJson(ls_ent);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("http://192.168.1.3:8080/wm1/rest/")
.addConverterFactory(GsonConverterFactory.create())

.build();

apiService.setEnInfo(jsonObject)

我自己摸索出问题了，原来在参数传递那里问题： @POST("Entity/Nameset") Observable<ExResult> setEnInfo(@Body Gson jsonObject); 下面是服务器WEB jax-rs 的代码： @POST @Path("/Nameset") @Produces(MediaType.APPLICATION_JSON + ";charset=" + "UTF-8") @Consumes(MediaType.APPLICATION_JSON + ";charset=" + "UTF-8") public ExResult Entiynameset(EntityStru enstru) { String ls_chname=""; String ls_enname=""; String ls_res="N"; ls_chname=enstru.getchnname(); ls_enname=enstru.getengname(); ExResult res=new ExResult(); res.setresultype("update-entity-name"); String sql = "update entity set chn_name='"+ls_chname+"',eng_name='"+ls_enname+"'"; long rs = 0; try { super.getConn(); pstmt = conn.prepareStatement(sql); rs = pstmt.executeUpdate(); if(rs>0){ ls_res="Y"; } } catch (Exception ex) { ex.printStackTrace(); } finally { try { super.closeAll(); } catch (Exception ex) { ex.printStackTrace(); } } res.setresult(ls_res); return res; } 传入和返回都是JSON数据结构 传入参数是个POJO，bean结构，但是在Android写成了JSON格式，改成 一样对应结构就可以了 Observable<ExResult> setEnInfo(@Body Gson jsonObject); 改成 Observable<ExResult> setEnInfo(@Body Entity ls_ent); 再修改按键响应里面的入参就可以了，另外Onnext那里要修改一下，因为onnext永远是要获取空值才停止，所以要先确认不是空值。

第一次用这个论坛，这个积分能分给自己不？自己发帖自己回答的。

[ludan_2016]

求帮助 Observable<ExResult> setEnInfo(@Body Entity ls_ent); 这里传入bean结构 那么 apiService.setEnInfo(jsonObject)还传jsonObject吗？

[ludan_2016]

能要个QQ 联系吗？ 详细请教下。

[WMERP]

一样的BEAN结构，你不管中间的，只要两边对上就行，不管中间是JSON还是XML传输，解析过程全部交给依赖包自动处理了

最近忙着搞ERP的功能开发，PB，我android也是个新手，QQ:3886580

我今天也出现你这样的问题了。
