解决办法:
修改 web.xml 中 DWR?配置信息
原:
<servlet>??
????? <servlet-name>dwr-invoker</servlet-name>??
??? ?<servlet-class>org.directwebremoting.spring.DwrSpringServlet</servlet-class>??
??? ?<init-param>?
???? ?<param-name>debug</param-name>?
??? ??<param-value>true</param-value>?
??</init-param>
</servlet>
?
加入跨域调用配置信息(红色部分)，修改为:
<servlet>??
????? <servlet-name>dwr-invoker</servlet-name>??
??? ??<servlet-class>org.directwebremoting.spring.DwrSpringServlet</servlet-class>??
??? ? <init-param>?
???? ??????? <param-name>debug</param-name>?
??? ???????? <param-value>true</param-value>?
????? </init-param>
??????<init-param>
??????????? ?<param-name>crossDomainSessionSecurity</param-name>
???????? ??? <param-value>false</param-value>
???? ?</init-param>
???? ?<init-param>
??????????? <param-name>allowScriptTagRemoting</param-name>
???????? ?? <param-value>true</param-value>
???? ?</init-param>
</servlet>
