Java:如何将值从类/ bean传递给servlet

public class MyBean {
    public void setValue(String value) {
        ServletRequest request = getServletRequest(); // 获取ServletRequest对象
        request.setAttribute("myValue", value);
    }
}

public class MyServlet extends HttpServlet {
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String value = (String) request.getAttribute("myValue");
        // 使用获取的值进行后续操作
    }
}

public class MyBean {
    private String value;

    public void setValue(String value) {
        this.value = value;
    }

    public String getValue() {
        return value;
    }
}

public class MyServlet extends HttpServlet {
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        MyBean myBean = new MyBean();
        myBean.setValue("myValue");
        request.setAttribute("myBean", myBean);
    }
}
