本地200行代码跑通RAG：PDF解析、向量检索与Phi-3生成实战检索增强生成（RAG）是一种将外部知识动态注入大语言模型的技术范式，其核心原理在于解耦‘记忆’（向量数据库）与‘推理’（LLM），通过精准语义检索突破模型静态知识截止和长上下文失焦瓶颈。技术价值体现在可控性、低延迟与离线部署能力，广泛应用于企业知识库问答、政策合规查询、内部文档智能助手等场景。本文聚焦工程落地，基于ChromaDB内存模式、BGE文本嵌入与本地量化Phi-3模型，详解PDF结构化解析、语义分块、向量入库及FastAPI服务封装，覆盖从零构建可调试、可扩展RAG系统的完整链路。阅读详情

（eclipse下）
建立一个输入user与password的LOGIN,

若user=password进入welcome，
若不等提示错误信息。

但提示出错：
org.apache.jasper.JasperException: Cannot find message resources under key org.apache.struts.action.MESSAGE

我的action:
package app;

import javax.servlet.http.*;
import org.apache.struts.action.*;

public final class LogonAction extends Action {

public ActionForward perform(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) {
String username = ((LogonForm)form).getUsername();
String password = ((LogonForm)form).getPassword();
if(!username.equals(password)) {
//ActionErrors errors = new ActionErrors();
//errors.add(ActionErrors.GLOBAL_ERROR,new ActionError("error.logon.invalid"));
//saveErrors(request,errors);
return(new ActionForward(mapping.getInput()));
}
HttpSession session = request.getSession();
session.setAttribute("user",form);
return(mapping.findForward("success"));
}
}
请大家帮忙，这里作揖了

哎呀，楼上大哥谢谢你啦，问题好像解决了，但我还有点不明白的是，我以为在web.xml里设置ApplicationResources呢!

我的web.xml
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/j2ee/dtds/web-app_2_3.dtd">
<web-app>
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>ApplicationResources</param-name>
<param-value>com.youcompany.struts.ApplicationResources</param-value>
</init-param>
<init-param>
<param-name>coinfig</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>2</param-value>
</init-param>
<init-param>
<param-name>detail</param-name>
<param-value>2</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<taglib>
<taglib-uri>/tags/struts-html</taglib-uri>
<taglib-location>/WEB-INF/struts-html.tld</taglib-location>
</taglib>
</web-app>

这里的<init-param>
<param-name>ApplicationResources</param-name>
<param-value>com.youcompany.struts.ApplicationResources</param-value>
</init-param>
不是在指定资源文件吗？而且我用的eclipse的easystruts不允许更改ApplicationResources！！
我有很多很糊涂的，还忘东东赐教，加我MSN:arqui2004@hotmail.com

资源文件放在WEB-INF/classes下
如果你的资源文件名为：ApplicationResources.properties
在struts-config.xml中配置如下：
<struts-config>
.....
<message-resources parameter="ApplicationResources" />
</struts-config>

资源文件如下：
welcome.title = Struts Logon Example Application
welcome.heading = Welcome!
welcome.message = To get started on your own application,copy the struts-blank.war to a new WAR file using the name for your
application.Place it in your container's "webapp" folder (or equivalent),and let your container auto-deploy the application Edit
skeleton configuration files as needed,reload Struts or restart your container,and you are on your way!(You can find
application.properties file with this message in the <B>/WEB-INF/src/java/resources</B> folder.)
errors.footer = </UL><HR>
errors.header = <H3><FONT color="red">Validation Error</FONT></H3>You must correct the following error(3) before
proceeding:<UL>
error.username.required = <LI>Username is required</LI>
error.password.required = <LI>Password is required</LI>
error.logon.invalid = <LI>Username and password provided not found inuser directory.Password must match exactly,including;
lower or upper case characters.</LI>
error.logon.connect = <LI>Could not connect to user directory.</LI>

感觉没有问题啊！！
