解决方法:
1、 在控制器处理方法上的@RequestMapping注解中配置produces
@RequestMapping(value="/getrolelist.html",produces={"application/json;charset=UTF-8"}) @ResponseBody public Object getRoleList(){ HashMap<String,List<Role>> resultMap=new HashMap<String, List<Role>>(); List<Role> roleList=roleService.getRoleList(); resultMap.put("roleList",roleList); for(Role role:roleList){ logger.info("角色id"+role.getId()+role.getRoleName()); } return JSONArray.toJSONString(roleList);//把resultMap转换成JSON格式返回 }
2、 在springMVC里配置StringHttpMessageConverter
<mvc:annotation-driven> <mvc:message-converters> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>application/json;charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven>
3、 1、2都试过了还是乱码,修改@RequestMapping value属性后缀名,试过几个后缀名,除了.html,都能正常返回中文
//修改value后缀名 @RequestMapping(value="/getrolelist.do",produces= {"application/json;charset=UTF-8"}) @ResponseBody //修改value后缀名 @RequestMapping(value="/getrolelist",produces={"application/json;charset=UTF-8"}) @ResponseBody
