在ssm框架中新增json支援其實很簡單。只需要幾步即可完成。

第一步：在spring-mvc.xml中配置

<!-- 輸出物件轉JSON支援 -->
<bean id="jsonConverter"
     class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
    <propertyname="supportedMediaTypes">
        <list>
           <value>application/json;charset=UTF-8</value>
        </list>
    </property>
</bean>
 

第二步：在controller方法頭上面添加註解@ResponseBody

@RequestMapping(value = "/list.json",produces = "application/json;charset=utf-8")
@ResponseBody
public EUDataGridResult list(Model model, Integer page, Integer rows,Longtaskid) throws Exception{
    EUDataGridResult result = new EUDataGridResult();
    PageInfo<DefenseGroup> pageInfo =defenseGroupService.listAll(page,rows,taskid);
    result.setTotal(pageInfo.getTotal());
    result.setRows(pageInfo.getList());
    return result;
}
 

這樣最終回傳的資料就會變成json格式了
