Cannot forward after response has been committed 错误解决

Cannot forward after response has been committed问题解决及分析 

 

这里使用旧框架中的jsp方式

  <!--地理信息查询（根据所属单位-->
  <action scope="request" attribute="geographicForm"
   name="geographicForm"
   path="/geographic_information_query_init"
   type="cn.edu.sdu.framework.bs.BaseAction">
   <forward name="next"
    path="/WEB-INF/jsp/housegraph/house_geographic_info_query.jsp"
    contextRelative="true" />
  </action>
  <!--Json方式写回数据，不需要写forward，若加上   type="cn.edu.sdu.framework.bs.BaseAction">
   <forward name="next"
    path="/WEB-INF/jsp/housegraph/house_geographic_info_query.jsp"
    contextRelative="true" />，则会报错：Cannot forward after response has been committed

-->
  <action scope="request" attribute="geographicForm"
   name="geographicForm"
   path="/geographic_information_query"
   type="cn.edu.sdu.framework.bs.BaseAction">
  </action>

 

说明：如果使用 type="cn.edu.sdu.framework.bs.BaseAction">，则需要自己再定义一下business-beans 中还需配置。若不用此type，则需自定义一种Action类型
