如何将变量从servlet传递到jsp页面? [英] How to pass variable from a servlet to a jsp page?

问题描述

我有一个servlet(前控制器)，它可以分析请求，准备一些必要的数据(模型)，然后将其传递给要呈现的jsp.

I have a servlet (front-controller), which analyse the request, prepare some necessary data (model) and then should pass it to the jsp to be rendered.

如何将数据从servlet传递到jsp? (我希望可以在request对象的参数映射中添加新参数，但是该映射不可修改.)

How should I pass the data from servlet to jsp? (I hoped that it was possible to add new parameters to parameters map in the request object, but that map is unmodifiable).

我可以向request添加属性，但是我不知道如何从jsp中检索它们.

I can add attributes to the request but I don't know how to retrieve them from the jsp.

所有数据都应在请求范围内.正确的方法是什么?

All the data should be in the request scope. What's the correct way?

推荐答案

我可以向请求中添加属性，但是我不知道如何从jsp中检索属性.
您无需专门检索"它们，只需引用它们即可

I can add attributes to the request but I don't know how to retrieve them from the jsp.
You don't need to specifically 'retrieve' them, just referring them works

request.setAttribute("titleAttribute", "kittens are fuzzy");

然后

Title here: ${titleAttribute}
