struts环境搭建

创建项目

  1. 在eclipse中新建一个web工程,新建工程的时同时勾选web.xml文件如下图:
    Snip20170322_6.png

  2. 下载好strtus文件包并解压缩,将以下jar包复制进入我们的项目lib包中

Snip20170322_7.png

  1. 找到lib目录下的web.xml文件并配置(struts版本不同过滤器写法会有差异)

  1. 此处我们可以创建一个action类,一般继承ActionSupport 执行默认方法execute(),此时返回一个字符串(此字符串用于标识并显示对应的jsp页面)

package com.entity;
import com.opensymphony.xwork2.ActionSupport;
public class IndexAction extends ActionSupport {
	@Override
	public String execute() throws Exception {
		// TODO Auto-generated method stub
		System.out.println("你是最帅的");
		return "handSomePig";
	}
}
  1. 配置struts.xml文件

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
    "http://struts.apache.org/dtds/struts-2.0.dtd">
    <!-- Add packages here -->
    <package name="com.entity"  extends="struts-default">
    	 <action name="Index" class="com.entity.IndexAction" method="execute">
            <result name="handSomePig">/WEB-INF/jsp/index.jsp</result>
       </action>
    </package>
</struts>

action

name: 用作客户端访问时的路径相当于Servlet’s path

method:与action类的方法所对应不写默认为execute方法

resultname:result中的name属性为其父标记所对应方法的返回值，不写默认为success

若返回值与name属性值匹配则完成result标记内指定的路径进行跳转到index.jsp

  1. 运行项目

如上图所示已经显示正常

spring环境搭建(实现查询数据库表以及简单注入)

  1. 加入spring开发所需的jar包(javadoc.jar/sources非必须,如图)

Snip20170322_11.png

  • 此外我们还需要加入commons-logging.jar包,用来记录程序运行时的活动的日志记录,该文件在struts2中的lib下可找到,一个struts2中的插件包(struts2-spring-plugin-2.3.30.jar)

  • mySql数据库因此还需加入数据库驱动包mysql-connector-java-5.1.39-bin.jar

  1. 配置struts文件、引入spring

spring注入之后耦合度降低

Hibernate 环境搭建

  1. 导入jar包

Snip20170322_13.png

  1. 需要在src目录下配置一个实体类映射文件这里以(Students.hbm.xml)为例
