spring2.5.6+struts2.1.6+jpa+annotation傻瓜教程

中国IT不缺牛人，缺的是我这样无私奉献的普通人

先装个MyEclipse吧 MyEclipse-7.0-win32.exe

涉及版权问题，key自己baidu吧

new一个web project jdk1.5以上(struts2.1之后好象只支持JDK1.5以上版本，懒得baidu了，应该没记错)

web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.4" 
	xmlns="http://java.sun.com/xml/ns/j2ee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

spring配置文件

    </bean>
    <!-- 打开事务annotation -->
    <tx:annotation-driven transaction-manager="transactionManager" />
	
</beans>

 在src建个META-INF文件夹，新建persistence.xml文件

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
    version="1.0">
    <persistence-unit name="punit">
    </persistence-unit>
</persistence>

 

接下来把jar包扔到WEB-INF/lib下，之所以要先写配置文件后扔jar包，是为了根据启动错误信息一步一步加jar包

链接给大家友情提供了 struts2.1.6    spring2.5.6

先把struts几个包拷出来

xwork-2.1.2.jar

struts2-core-2.1.6.jar

freemarker-2.3.13.jar

ognl-2.6.11.jar

commons-fileupload-1.2.1.jar

commons-logging-api-1.1.jar

struts2-convention-plugin-2.1.6.jar

struts2-spring-plugin-2.1.6.jar

接下来是spring

spring.jar

然后是hibernate，不用另外下载hibernate，spring的lib文件夹里就有了，慢慢找，顺便熟悉下结构

hibernate3.jar

hibernate-annotations.jar

hibernate-entitymanager.jar

hibernate-commons-annotations.jar

slf4j-api-1.5.0.jar

slf4j-log4j12-1.5.0.jar

log4j-1.2.15.jar

asm-2.2.3.jar

cglib-nodep-2.1_3.jar

antlr-2.7.6.jar

dom4j-1.6.1.jar

javassist-3.4.GA.jar

persistence.jar

jta.jar

c3p0-0.9.1.2.jar

commons-collections.jar

最后是oracle驱动包，oracle安装目录下jdbc文件夹里有

ojdbc14.jar

配置就此结束

有人要问，为啥没有struts.xml文件呢，呵呵，用annotation做了

BaseAction.java 基类，继承ActionSupport类和Preparable接口

package com.demo.action;

import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.Preparable;

public class BaseAction extends ActionSupport implements Preparable {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	public void prepare() throws Exception {
		// TODO Auto-generated method stub
		
	}

}

 TestAction.java 继承BaseAction

 

package com.demo.action;

import org.apache.struts2.convention.annotation.Action;
import org.apache.struts2.convention.annotation.Result;

public class TestAction extends BaseAction {

	/**
	 * 
	 */
	private static final long serialVersionUID = 1L;

	@Action(value = "foo", 
			results = { @Result(name = "success", location = "/pages/welcome.jsp") }
	)
	public String test() {
		return SUCCESS;
	}

}

 

在WebRoot下建个pages文件夹，里面放个welcome.jsp文件，上面的就能看明白了

 

欢迎大家批评！
