解决问题的思路：

1、分析比对http请求头，contentType等设置

2、前段编码，后端解码，这个方式比较落麻烦，凡是有中文乱码的地方都要进行解决

3、修改Tomcat的默认编码，tomcat8以下默认编码是"iso8859-1"，tomcat8默认编码是“UTF-8”

4、查看应用的web.xml默认编码是否是"UTF-8"以下是后端强制转码配置

<filter>
<filter-name>Set Character Encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>

按照此种写法HttpServletRequest和HttpServletResponse在控制层是不可缺少的，否则有乱码

/**数据透传下发记录*/
@RequestMapping("sendTransparentinfoSendCmd")
public Object sendTransparentinfoSendCmd(TransparentinfoSendlog transparentinfoSendlog,HttpServletResponse response,HttpServletRequest request){
if(transparentinfoSendlog.getVehicleId()==null){
// 未选择车辆
return setReturnMap(false, HttpCode.NO_SELECT_VEHICLE.value());
}
String sim=terminalService.findMobileCodeByVehicleId(transparentinfoSendlog.getVehicleId()+"");
if(sim==null||sim.equals("")){
return setReturnMap(false, HttpCode.ORDER_SEND_NO_SIM.value());
}
if(transparentinfoSendlog.getEnterpriseId()==null){
// 没有公司ID
return setReturnMap(false, HttpCode.BAD_REQUEST_ENTERPRISE.value());
} // 存储数据透传下发发送日志
OrderInfo orderInfo=new OrderInfo();
orderInfo.setId(com.cvnavi.util.WebUtil.getPK());
User user = WebExecutionContext.getUser();
orderInfo.setUserId(user.getId());//设置userId
// 设置指令ID
transparentinfoSendlog.setOrderId(orderInfo.getId());
boolean flag=iTransparentinfoService.insertTransparentinfoSendlog(transparentinfoSendlog);
if(!flag){
return setReturnMap(false, HttpCode.BAD_REQUEST.value());//请求错误
}
// 发送指令到网关
orderInfo=iOrderInfoService.sendTransparentinfoSendlogCmd(orderInfo,transparentinfoSendlog);
if(orderInfo==null){
return setReturnMap(false, HttpCode.BAD_REQUEST.value());//请求错误
}
if("0".equals(orderInfo.getStatus())){
return setReturnMap(false, HttpCode.NO_VEHICLE_ONLINE.value());//车辆不在线
}else if("-1".equals(orderInfo.getStatus())){
return setReturnMap(false, HttpCode.ORDER_SEND_FAIL.value());//指令发送失败
}
return setReturnMap(true, HttpCode.OK.value());
}
