JDK环境变量配置:
至 http://www.oracle.com/ 下载jdk
(dos下 “set 环境变量名”可以查看环境变量值,“set 环境变量名=D:\XX”可以修改环境变量)
新建环境变量JAVA_HOME值为jdk的安装目录,例:D:\jdk1.7.0
编辑系统变量path,添加:%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;
新建环境变量CLASSPATH:.;%JAVA_HOME%\lib;%JAVA_HOME%\lib\tools.jar
测试:dos下 java –version显示jdk版本信息
Tomcat配置:
至http://tomcat.apache.org/下载tomcat文件(压缩包或安装包)
正确配置jdk
新建环境变量:CATALINA_HOME值为tomcat所在目录,例:D:\Tomcat8
(Dos 下运行startup.bat,可以查看错误信息)Spring配置
下载spring-framework-3.2.0.RELEASE-dist.zip类似文件,使用spring还需必备包commons-logging.jar,将 此文件夹下的commons-logging.jar文件至spring目录下的lib文件夹内。commons-logging.jar 可至 commons-logging.jar下载
Myeclipse添加tomcat及spring支持
1、 Tomcat
window->perferences->myeclipse->servers->tomcat选择对应版本,选中enable,在tomcat home directory中选择tomcat安装的根目录(或者解压路径),其余2个将自动选择
2、 Spring
Javaproject->BuldPath->configure Buld Path->Librares标签->Add Externaljars…,选择spring的lib目录下的所有以RELEASE.jar结尾的jar核心文件文件,包括commons-logging.jar
测试:
1、测试环境配置是否成功:在myeclipse中新建javaproject名为HelloWordd
在src下新建包名为com.inter->在com.inter包下新建HolleMessage类:
package com.inter;
public interface HelloMessage {
void message();//定义抽象的message方法
}
在src下新建包名为com.bean->在com.bean包下新建HolleBeauty类:
package com.bean;
import com.inter.HelloMessage;
public class HelloBeauty implements HelloMessage{
@Override
public void message() {
// TODO Auto-generated method stub
System.out.println("HelloBeautifulWord");
}
}
在src下新建包名为com.test->在com.test包下新建test类:
package com.test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
import com.bean.HelloBeauty;
public class test {
public static void main(String[] args){
ApplicationContext ac=new FileSystemXmlApplicationContext("src/applicationContext.xml");//利用文件系统查询applicationContext.xml配置文件
HelloBeauty b = (HelloBeauty) ac.getBean("beauty");
b.message();
}
}
在src下新建xml配置文件名为applicationContext.xml:
<?xml version="1.0" encoding="UTF-8"?>
<beans
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="beauty" class="com.bean.HelloBeauty"></bean>
</beans>
运行显示:HelloBeautifulWord 则配置成功
2、myeclipse+tomcat+web测试
新建web project名为HelloWeb
HelloWeb->src下新建包com.index->新建Hello.java:
package com.index;
public class Hello {
private String message = "Hello World";
/** * @return Returns the message. */
public String getMessage(){
return message;
}
/** * @param message The message to set. */
public void setMessage(String message){
this.message = message;
}
}
在WebRoot下找到index.jsp,修改:
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<jsp:useBean id="hello" class="com.index.Hello" scope="page"></jsp:useBean>
<jsp:setProperty name="hello" property="message" value="hello word"></jsp:setProperty>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
<%=hello.getMessage() %><br>
</body>
</html>
在myeclipse窗口中:
(window->perferences->myeclipse->servers->tomcat选择对应版本,选中enable,在tomcat home directory中选择tomcat安装的根目录(或者解压路径),其余2个将自动选择)
右键web项目->myeclipse->add and remove project deployment选择添加的tomcat服务器,点击add。
Myeclipse界面正下方选择servers标签页,选择服务器右键->Run server
服务器启动成功后,默认配置下,至网页访问:localhost:8080 可以看见tomcat版本信息,访问 localhost:8080/HelloWeb/ 页面显示 :Hello Word 则配置成功
