java web 将http 强转为https

在web.xml中添加如下：

<!-- add by jim -->
<security-constraint>
    <web-resource-collection>
        <web-resource-name>SSL</web-resource-name>
<!-- 任意url -->
        <url-pattern>/*</url-pattern>
    </web-resource-collection>
    <user-data-constraint>
        <transport-guarantee>CONFIDENTIAL</transport-guarantee>
    </user-data-constraint>
</security-constraint>

服务器为resin，需要在confi.xml文件中添加

   <http port='443'>
       <jsse-ssl>
     <key-store-file>dyxnettest.jks</key-store-file>
     <password>test123</password></jsse-ssl>
  </http>
