Java 从数据库获取记录并显示在struts网页上

我的问题是如何从数据库表中获取记录并将其显示在struts网页上。我已将代码粘贴到下面。当我运行这段代码时，我没有得到任何错误，但是即使该表包含许多记录，也不会显示该表。我用谷歌搜索了一下，但找不到答案。即使是SO的类似解决方案也帮不了我。。提前谢谢

package example;

public class SplitConfig {

    private String file_id;
    private String category;

    public String getFile_id() {
        return file_id;
    }

    public void setFile_id(String file_id) {
        this.file_id = file_id;
    }

    public String getCategory() {
        return category;
    }

    public void setCategory(String category) {
        this.category = category;
    }

}

package example;

import com.opensymphony.xwork2.ActionSupport;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;

import java.util.ArrayList;

public class SplitConfigAction extends ActionSupport {

    private ArrayList<SplitConfig> list = new ArrayList<SplitConfig>();

    public ArrayList<SplitConfig> getList() {
        return list;
    }

    public void setList(ArrayList<SplitConfig> list) {
        this.list = list;
    }

    public SplitConfigAction() {
    }

    public String execute() throws Exception {
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            Connection con = DriverManager.getConnection("jdbc:sqlserver://192.168.100.25:1433;databaseName=db_h2h;user=sa;password=123");
            PreparedStatement ps = con.prepareStatement("select * from reporttracking.dbo.FILE_MASTER");
            ResultSet rs = ps.executeQuery();
            while (rs.next()) {
                SplitConfig sc = new SplitConfig();
                sc.setFile_id(rs.getString(1));
                sc.setCategory(rs.getString(2));
                list.add(sc);

            }
            con.close();
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }
        return "success";
    }

我为splitcon操作编写了不同的类名。。。类应该是SplitConfigAction而不是ShowSplitAction…

是否成功映射到重定向或重定向操作结果？否。。它没有被映射。。重定向将做什么？？？请发布你的struts.xml也发布你的web.xml我得到了解决方案。。。我为splitcon操作编写了不同的类名。。。类应该是SplitConfigAction而不是ShowSplitAction。。。谢谢大家
