在Struts 2中使用bean值定制日志记录拦截器 [英] Customized Logging interceptor with bean value in Struts 2

问题描述

我正在编写用于审计日志目的的自定义拦截器.我想在拦截器中获取会话属性和请求属性.

I am writing a customized interceptor for audit logs purpose. I want to get session attributes and request attributes in interceptor.

例如:我将 Username 设置为会话，而我也得到了.

For example: I'll set Username into session and that I am getting too.

但是挑战是:我将一个bean定义为审计bean，在其中我将一些值设置为bean

But the challenge is: I am defining one bean as audit bean where I am setting some values to bean

if (this.userName.equals("admin")) {
    user.setUserName(this.userName);
    sessionAttributes.put("USER", user);
    auditBean.setPerm("login success");
    requestAttributes.put("auditBean", auditBean);
    return "success";
} else {
    auditBean.setPerm("Login Failed initiaqlized");
    requestAttributes.put("auditBean", auditBean);
    addActionError(getText("error.login"));
    
    return "error";
}

此请求属性是 ServletRequestAware obj.但是此审计bean我无法检索到拦截器中，请对此提供帮助.

this request attribute is ServletRequestAware obj. But this audit bean I am not able to retrieve into the interceptor, please help regarding this.

Map<String, Object> sessionAttributes = invocation.getInvocationContext().getSession();

实现这样的会话.

Map<String, Object> requestAttributes = invocation.getInvocationContext().getParameters();

上面的

我无法检索请求参数.它显示的是JSP请求参数，但不是我已经设置的.

with above I am not able to retrieve request params. It's showing JSP request params, but not that I have set in action.

推荐答案

您可以检查拦截器中的调用上下文是否是您的操作上下文，然后直接从上下文映射中获取它.

You can check that an invocation context in your interceptor is your action context, then get it directly from the context map.

Map<String, Object> requestAttributes = (Map<String, Object>) invocation.getInvocationContext().get("request");

或使用其他语法

Map requestAttributes = (Map) ActionContext.getContext().get("request");
