maven搭建Struts2+Hibernate+Spring

注：本文用的是PostgreSQL,所以引的包和数据库配置也是PostgreSQL的，可以根据自己需要修改即可

1.建立maven工程

(1)File->New->Maven Project

(2)点击Next

(3) 选中默认的maven-archetype-quickstart,点击Next

(4)输入Group Id和Artifact Id，点击Finish

(5)添加Source Folder src/main/resources

然后在Folder name中输入src/main/resources，点击Finish

(6)配置Build Path

右键项目->Build Path->Configure Build Path...

设定Source中的输出Output folder，双击修改

分别修改输出路径为

src/main/resources　　对应　　target/classes

src/main/java　　对应　　target/classes

src/test/java　　对应　　target/test-classes

(7)设定Libraries

Libraries->Add Library

点击Finish

点击OK，配置完后目录结构如下：

2.转换为web项目

右键项目->Properties->Project Facets,选中Dynamic Web Module，更换version，然后点击Further configuration available...

修改Content directory 为 src/main/webapp ,单击OK,跳到外面一层继续点击OK即可:

3.设置部署程序集(Web Deployment Assembly)

在项目上右键单击，选择Properties，在左侧选择Deployment Assembly

4.设置部署时的文件发布路径

　　1，我们删除test的一项，因为test是测试使用，并不需要部署。
　　2，设置将Maven的jar包发布到lib下。
　　　　Add -> Java Build Path Entries -> Maven Dependencies -> Finish

　　设置完成后如图

ok后，web项目就创建完毕

5.修改pom文件

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

6.增加配置文件

(1)新建struts.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>

    <!-- 指定由spring负责action对象的创建 -->
    <constant name="struts.objectFactory" value="spring" />
    <!-- 所有匹配*.action的请求都由struts2处理 -->
    <constant name="struts.action.extension" value="action" />
    <!-- 是否启用开发模式(开发时设置为true,发布到生产环境后设置为false) -->
    <constant name="struts.devMode" value="true" />
    <!-- struts配置文件改动后，是否重新加载(开发时设置为true,发布到生产环境后设置为false) -->

    <constant name="struts.serve.static.browserCache" value="false" />

    <constant name="struts.i18n.encoding" value="utf-8" />
    <!-- 每次HTTP请求系统都重新加载资源文件，有助于开发(开发时设置为true,发布到生产环境后设置为false) -->
    <constant name="struts.i18n.reload" value="true" />
    <!-- 文件上传最大值 -->

    <constant name="struts.enable.DynamicMethodInvocation" value="true" />

    <!-- 对于WebLogic,Orion,OC4J此属性应该设置成true -->
    <constant name="struts.dispatcher.parametersWorkaround" value="false" />

    <package name="basePackage" extends="struts-default">


    </package>

</struts>

(2)新建spring.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://www.springframework.org/schema/context

">

    <!-- 引入属性文件,config.properties位于src/main/resources目录下 -->
    <context:property-placeholder location="classpath:config.properties" />

    <!-- 自动扫描dao和service包(自动注入) -->
    <context:component-scan base-package="com.ccc.dao,com.ccc.service,com.ccc.service.impl,com.ccc.dao.impl" />

</beans>

(3) 新建spring-hibernate文件

(4)新建config.properties文件

#hibernate.dialect=org.hibernate.dialect.OracleDialect
#driverClassName=oracle.jdbc.driver.OracleDriver
#validationQuery=SELECT 1 FROM DUAL
#jdbc_url=jdbc:oracle:thin:@127.0.0.1:1521:orcl

#jndiName=java:comp/env/dataSourceName

hibernate.hbm2ddl.auto=update
hibernate.show_sql=true
hibernate.format_sql=true
hibernate.temp.use_jdbc_metadata_defaults false

(5)修改web.xml

7.相关代码

目录结构如图：

(1)TestAction

package com.ccc.action;

import java.util.Date;
import java.util.UUID;

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