使用ajax提交的json数据,产生筹码问题

使用ajax提交的json数据，我们必须添加produces注解，如下所示。否则将会产生乱码
    方法一：添加produces注解
           @ApiOperation(value = "删除日志")
               @RequiresPermissions("upms:log:delete")
               @RequestMapping(value = "/delete/{ids}", method = RequestMethod.GET,produces = "text/html;charset=UTF-8")
               @ResponseBody
               public Object delete(@PathVariable("ids") String ids) {
                   int count = upmsLogService.deleteByPrimaryKeys(ids);
                   return new UpmsResult(UpmsResultConstant.SUCCESS, count);
               }
    方法二：在tcbds-common项目的springMVC-servlet.xml文件,添加<value>application/json;charset=UTF-8</value>
         <!-- 返回ResponseBody响应类型 -->
            <mvc:annotation-driven>
                <mvc:message-converters>
                    <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                        <property name="supportedMediaTypes">
                            <list>
                                <value>text/html;charset=UTF-8</value>
                                <value>application/json;charset=UTF-8</value>
                            </list>
                        </property>
                    </bean>
                </mvc:message-converters>
            </mvc:annotation-driven>
