我如何在@service类中获得HttpServletRequestObject [英] How do I get HttpServletRequestObject in the @service class

问题描述

我成功地整合了Spring和Spring4GWT。
一切正常。

我唯一遇到的问题是如何得到 HttpServletRequestObject 在 @service 类中？

一些配置和代码

web.xml

 < servlet> 
< servlet-name>测试< / servlet-name> 
< servlet-class> org.spring4gwt.server.SpringGwtRemoteServiceServlet< / servlet-class> 
  1< / load-on-startup> 
< / servlet> 
< servlet-mapping> 
< servlet-name>测试< / servlet-name> 
< url-pattern> / ui / test / *< / url-pattern> 
< / servlet-mapping> 
  

服务类别

  public class LoginServiceImpl实现ILoginService {
 
 private IUserService userService; 
 public LoginServiceImpl（IUserService userService）{
 super（）; 
 this.userService = userService; 
 
 $ b $ public boolean isAuthenticUser（String userName，String password）{
 // operation 
} 
} 
  LoginServiceImpl 中我无法获得Servlet对象。 
我在这里需要它，以便我可以将它用于不同的目的。
 
 
 
任何想法？ 
 
解决方案
最后，我得到了一个解决方案。 
如果有人想要在GWT-RPC服务中访问HttpServletrequest，那么以下内容可以提供帮助。
 
 
 
修改web.xml 
 
 
 
 < filter> 
< filter-name> springRequestFilter< / filter-name> 
< filter-class> org.springframework.web.filter.RequestContextFilter< / filter-class> 
< / filter> 
< filter-mapping> 
< filter-name> springRequestFilter< / filter-name> 
< url-pattern> / your_pattern / *< / url-pattern> 
< / filter-mapping> 
  
 
 
 
服务中
 
 
 
  ServletRequestAttributes sra =（（ServletRequestAttributes）RequestContextHolder.currentRequestAttributes（））; 
 sra.getRequest（）; 
  
希望这有帮助
 
I'm successfully able to integrate Spring and Spring4GWT.
Everything is working fine.

The only problem I'm facing is How do I get HttpServletRequestObject in the @service class?

Some of the configuration and code

web.xml

<servlet>
        <servlet-name>test</servlet-name>
        <servlet-class>org.spring4gwt.server.SpringGwtRemoteServiceServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>test</servlet-name>
        <url-pattern>/ui/test/*</url-pattern>
    </servlet-mapping>


Service class

public class LoginServiceImpl implements ILoginService {

    private IUserService userService;
    public LoginServiceImpl(IUserService userService) {
        super();
        this.userService = userService;
    }

    public boolean isAuthenticUser(String userName, String password) {
        // operation
    }
}
In LoginServiceImpl I'm not able to get the Servlet object.
I need it here so that I can use it for different purposes.

Any Idea?
解决方案
Finally I got a solution for it.
If someone wants to have access of the HttpServletrequest in the GWT-RPC service then the following can help.

Modify web.xml

<filter>
    <filter-name>springRequestFilter</filter-name>
    <filter-class>org.springframework.web.filter.RequestContextFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>springRequestFilter</filter-name>
    <url-pattern>/your_pattern/*</url-pattern>
</filter-mapping>


In Service

ServletRequestAttributes sra = ((ServletRequestAttributes)RequestContextHolder.currentRequestAttributes());
sra.getRequest();
Hope this is helpful
