[待解决问题]
先说明下需求，后台接收POST请求，返回json格式数据：
测试工具火狐插件：HTTP Requester
现在的问题是本地测试没有问题，但把程序部署到服务器上就报错；
代码如下：
@RequestMapping(value = "/login", method = RequestMethod.POST) @ResponseBody public Object login(@RequestParam String account, String pwd) { int result = -1; BasAccount ba = null; if (account != null && pwd != null) { result = basAccountService.login(account, pwd); }
Map map = new LinkedHashMap(); if (result == 1) { map.put("state", 1); map.put("id", Conversion.Bytes2HexString(ba.getId())); map.put("account", ba.getAccount()); return map; } }
@RequestMapping(value = "/login", method = RequestMethod.POST) @ResponseBody public Object login(@RequestBody BasAccount b) { String account = b.getAccount(); String pwd= b.getPwd(); int result = -1; BasAccount ba = null; if (account != null && pwd != null) { result = basAccountService.login(account, pwd); } Map map = new LinkedHashMap(); if (result == 1) { map.put("state", 1); map.put("id", Conversion.Bytes2HexString(ba.getId())); map.put("account", ba.getAccount()); return map; } }
请求映射里面加上consumes="application/json",produces="application/json;charset=UTF-8",也没效果；
返回的错误页面：

另外，另一个接口：
@RequestMapping(value = "/advice", method = RequestMethod.POST) @ResponseBody public Map<String, Object> advice(@RequestParam String account, String advice) {
同样的写法，在服务器上这个是可以调通的
本地的数据库和服务器上的表、视图和存储过程都一样
求大神帮忙，问题是出在哪里呢？
