How can you pass data from a Filter to the endpoint in Jersey

问题

Can you pass some data from a javax.servlet.Filter to a Jersey endpoint without using ThreadLocal or HttpSession?

And because the first question will be "why do you want to do this?": mostly curious. In practice I think I could use this to pass some data generated during authentication to the endpoint. Not using ThreadLocal eliminates the temptation to use that down the chain (hope there's no need to explain why that's evil) and not using HttpSession is more of a quirk :)

回答1:

Try injecting with @Context. I'm not sure what object you will receive though (somewhere I saw WebServiceContext, which is jax-ws), but it should contain the HttpServletRequest. so you will be a able to set request attributes in the filter and read them in the rest service
