在不丢失Struts2中请求属性的情况下进行重定向

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts2.ServletActionContext;

public class MyAction {
    public String execute() {
        // 获取HttpServletRequest对象
        HttpServletRequest request = ServletActionContext.getRequest();
        
        // 设置请求属性
        request.setAttribute("attributeName", "attributeValue");
        
        // 获取HttpServletResponse对象
        HttpServletResponse response = ServletActionContext.getResponse();
        
        try {
            // 进行重定向
            response.sendRedirect("redirectUrl?attributeName=" + request.getAttribute("attributeName"));
        } catch (Exception e) {
            e.printStackTrace();
        }
        
        return null;
    }
}
