用layui table接收到的后台数据是中文乱码。

用的是springmvc，设置和请求和响应还有tomcat都是utf-8还是乱码。

最后找到原因：

改之前

@RequestMapping(value = "/querycustom",method = RequestMethod.POST,produces ={"text/html;charset=UTF-8;", "application/json;"})

@ResponseBody

public Object queryCustomByWhere(

@RequestParam("CUS004") String CUS004,

@RequestParam("industry") String industry,

@RequestParam("salesman") String salesman,

@RequestParam("CUS013") String CUS013,

@RequestParam("CUS009start") String CUS009start,

@RequestParam("CUS009end") String CUS009end,

@RequestParam("CUS011start") String CUS011start,

@RequestParam("CUS011end") String CUS011end

) {

String strWhere = "1=1";

if (!StringUtils.isEmpty(CUS004))

strWhere += " AND CUS004='" + CUS004 + "'";

if (!StringUtils.isEmpty(industry))

strWhere += " AND CUS010='" + industry + "'";

if (!StringUtils.isEmpty(salesman))

strWhere += " AND CUS012='" + salesman + "'";

if (!StringUtils.isEmpty(CUS013))

strWhere += " AND CUS013='" + CUS013 + "'";

if (!StringUtils.isEmpty(CUS009start))

strWhere += " AND CUS009>='" + CUS009start + "'";

if (!StringUtils.isEmpty(CUS009end))

strWhere += " AND CUS009<='" + CUS009end + "'";

if (!StringUtils.isEmpty(CUS011start))

strWhere += " AND CUS011>='" + CUS011start + "'";

if (!StringUtils.isEmpty(CUS011end))

strWhere += " AND CUS011<='" + CUS011end + "'";

ListcustomPage = custemInfoService.findAllByWhere(strWhere);

Mapdatasource=new LinkedHashMap();

datasource.put("code",0);

datasource.put("count",2);

datasource.put("data",customPage);

Gson gson=new Gson();

String result=gson.toJson(datasource);

return result;

}

改之后

@RequestMapping(value = "/querycustom",method = RequestMethod.POST,produces ={"text/html;charset=UTF-8;", "application/json;"})

@ResponseBody

public Object queryCustomByWhere(

@RequestParam("CUS004") String CUS004,

@RequestParam("industry") String industry,

@RequestParam("salesman") String salesman,

@RequestParam("CUS013") String CUS013,

@RequestParam("CUS009start") String CUS009start,

@RequestParam("CUS009end") String CUS009end,

@RequestParam("CUS011start") String CUS011start,

@RequestParam("CUS011end") String CUS011end

) {

String strWhere = "1=1";

if (!StringUtils.isEmpty(CUS004))

strWhere += " AND CUS004='" + CUS004 + "'";

if (!StringUtils.isEmpty(industry))

strWhere += " AND CUS010='" + industry + "'";

if (!StringUtils.isEmpty(salesman))

strWhere += " AND CUS012='" + salesman + "'";

if (!StringUtils.isEmpty(CUS013))

strWhere += " AND CUS013='" + CUS013 + "'";

if (!StringUtils.isEmpty(CUS009start))

strWhere += " AND CUS009>='" + CUS009start + "'";

if (!StringUtils.isEmpty(CUS009end))

strWhere += " AND CUS009<='" + CUS009end + "'";

if (!StringUtils.isEmpty(CUS011start))

strWhere += " AND CUS011>='" + CUS011start + "'";

if (!StringUtils.isEmpty(CUS011end))

strWhere += " AND CUS011<='" + CUS011end + "'";

ListcustomPage = custemInfoService.findAllByWhere(strWhere);

Mapdatasource=new LinkedHashMap();

datasource.put("code",0);

datasource.put("count",2);

datasource.put("data",customPage);

return datasource;

}

本来@ResponseBody代表返回json格式，我又用Gson转了一次，所以有问题。
