[英]app engine simple java webservice
I like to expose one JAVA method as a Web service that will accept POST
,strip the parameters out of it and reply accordingly. 我喜欢将一个JAVA方法暴露为接受
POST
的Web服务 ,从中删除参数并相应地进行回复。 I read I have to use doPost(req,resp)
, but How can I get to the servlet code? 我读过我必须使用
doPost(req,resp)
,但是如何才能获得servlet代码? what should be in web.xml
? 什么应该在
web.xml
? there will not be a welcome-file ? 不会有欢迎档案? After mapping the servlet, can I read it without the need for a
index.html
as start point? 在映射servlet之后,我是否可以在不需要
index.html
作为起点的情况下阅读它?
create the doPost(req,resp)
method in your servlet and map it to a url in web.xml
在servlet中创建
doPost(req,resp)
方法,并将其映射到web.xml
的url
<servlet>
<servlet-name>HelloPost</servlet-name>
<servlet-class>packageName.HelloPost</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloPost</servlet-name>
<url-pattern>/post-url</url-pattern>
</servlet-mapping>
then you can post your request to /post-url
.You don't need to use index.html.Any url can be put in welcome file to load for the url /
To set /post-url
as landing page , use 然后你可以将你的请求发布到
/post-url
。你不需要使用index.html.Any url可以放在欢迎文件中加载url /
设置/post-url
作为登陆页面,使用
<welcome-file-list>
<welcome-file>/post-url</welcome-file>
</welcome-file-list>
