Question

我有一个带有下拉框和文本框的html页面。

在下拉列表中单击选项时，必须使用java或java脚本（无数据库）在文本框中填充.properties文件中的值。

我的属性文件：

 servers=Demo
 serversTolookfor=Links,name
 Demo_name=Demo Server
 Demo_Links=https://mobileapplication.gh:8080

server.html：

＆＃13;

<table class="edit" cellpadding="15"><tr>
    <td style="color: white;" >Server Name:</td> 
    <td align="right"><selectname="serverName" class="dropdown">
    <option value="Demo Server">Demo Server</option>
    </select></td></tr>
    <tr><td align="left" style="color: white;" >Server Link:</td><td align="right"><input type="text" name="server"></td>  
   </tr>
     </table>
     <input type="Submit" value="Save">

＆＃13;

Answer 1

在你的jsp（不要使用html文件）文件中使用占位符。

春季配置

<util:properties id="propertyConfigurer" 
                  location="classpath:yourPropertyFileClasspathHere "/>
<context:property-placeholder properties-ref="propertyConfigurer" />

<强> JSP

<spring:eval expression="@propertyConfigurer.getProperty('propertyNameHere')" />

Answer 2

我希望你这样想：

config.properties内容

#Crunchify Properties
user=Crunchify
company1=Google
company2=eBay
company3=Yahoo

CrunchifyReadConfigMain.java

package crunchify.com.tutorial;

import java.io.IOException;

public class CrunchifyReadConfigMain {

    public static void main(String[] args) throws IOException {
        CrunchifyGetPropertyValues properties = new CrunchifyGetPropertyValues();
        properties.getPropValues();
    }
}

CrunchifyGetPropertyValues.java

package crunchify.com.tutorial;

import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.util.Date;
import java.util.Properties;

public class CrunchifyGetPropertyValues {

    public String getPropValues() throws IOException {

        String result = "";
        Properties prop = new Properties();
        String propFileName = "config.properties";

        InputStream inputStream = getClass().getClassLoader().getResourceAsStream(propFileName);

        if (inputStream != null) {
            prop.load(inputStream);
        } else {
            throw new FileNotFoundException("property file '" + propFileName + "' not found in the classpath");
        }
        Date time = new Date(System.currentTimeMillis());
        // get the property value and print it out
        String user = prop.getProperty("user");
        String company1 = prop.getProperty("company1");
        String company2 = prop.getProperty("company2");
        String company3 = prop.getProperty("company3");

        result = "Company List = " + company1 + ", " + company2 + ", " + company3;
        System.out.println(result + "\nProgram Ran on " + time + " by user=" + user);
        return result;
    }
}

输出：

Company List = Google, eBay, Yahoo
Program Ran on Mon Feb 23 21:54:55 PDT 2015 by user=Crunchify

Answer 3

如果你想在普通的jsp中使用以下代码：

<%@ page import="java.io.FileInputStream"%>
<%@ page import="java.util.Properties"%>

<%
    Properties property = null;
    FileInputStream fis = new FileInputStream("path of A.properties") ;
    property =new Properties();
    property.load(fis);
    String username = property.getProperty("username"); 
%>
