在基于CXF的webservice中访问HttpServletRequest的方法
基于CXF开发webservice,想在webservice实现类中获得HttpServletRequest对象,用了几种方式,用@Resources标签或者@Context标签都不行。@Context标签下对象为null,@Resource标签虽然注入了org.apache.cxf.jaxws.context.WebServiceContextImpl了WebServiceContext 对象,但是该对象内部值为null,什么也取不到。
?
后面用了个笨办法,在web.xml中增加一个filter
?
<filter><filter-name>ContextServlet</filter-name><filter-class>xxx.filter.ContextServlet</filter-class></filter><filter-mapping><filter-name>ContextServlet</filter-name><url-pattern>/services/*</url-pattern></filter-mapping>
?
?
在filter中访问HttpServletRequest,将需要获得的值保存在ThreadLocal中
?
public static ThreadLocal<String> path = new ThreadLocal<String>();@Overridepublic void destroy() {path.remove();}@Overridepublic void doFilter(ServletRequest arg0, ServletResponse arg1,FilterChain arg2) throws IOException, ServletException {HttpServletRequest request=(HttpServletRequest)arg0; String path = request.getContextPath();basePath.set(path);arg2.doFilter(arg0, arg1);}
?
这样,在webservice的实现类中只要用?ContextServlet.path.get()就可以获得当前HttpServletRequest对中中的变量。?
