maven 整合struts2，mybaitis，spring使用drudi数据源

这几天一直在搭struts2，mybatis，spring的整合框架，作为一个新手，实在是不容易，看了很多文档和资料，期间出了很多问题，不过最后总算是搭出来了。记录下来，作为以后的参考，以及现在的温习。

1.首先，我用maven新建了一个webapp项目（纯粹的maven web项目），pom.xml中jar文件配置如下：

</dependency>
在网上看到别人整合struts2和spring的时候说有jar包冲突的问题，这里我没有遇到。
2.我用mybatis-generator工具自动生成了bean.mapper.和mapping三个文件。熟悉mybatis的都熟悉这三者之间的映射关系，这里就不解释了。工程目录如下：

3第三点也是最重要的一点，就是spring的配置，这里我们把spring配置和mybatis的配置放在一个文件里面了，applicationContext-core.xml文件配置如下：
<?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="

<bean id="installService" parent="baseTransactionProxy">

<property name="target" ref="installServiceImpl"/>

</bean>

<bean id="installAction" class="com.testStruts.action.InstallAction">

<property name="installService" ref="installService" />

</bean>

</beans>

4.写我们的Service和service实现类

package com.testStruts.service;

import java.util.Date;

import org.springframework.beans.factory.annotation.Autowired;

import com.testStruts.bean.FlowInstallTarget;

import com.testStruts.mapper.FlowInstallTargetMapper;

public class InstallServiceImpl implements InstallService {

private FlowInstallTargetMapper flowInstallTargetMapper;

public FlowInstallTargetMapper getFlowInstallTargetMapper() {

return flowInstallTargetMapper;

}

@Autowired

public void setFlowInstallTargetMapper(

FlowInstallTargetMapper flowInstallTargetMapper) {

this.flowInstallTargetMapper = flowInstallTargetMapper;

}

public FlowInstallTarget selectByPrimaryKey(Date date) {

return flowInstallTargetMapper.selectByPrimaryKey(date);

}

}

service的接口从中抽出即可。

5.再然后是Action类

package com.testStruts.action;

import java.util.Calendar;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.web.bind.annotation.ResponseBody;

import com.alibaba.fastjson.JSON;

import com.opensymphony.xwork2.ActionSupport;

import com.sun.servicetag.Installer;

import com.testStruts.service.InstallService;

public class InstallAction extends ActionSupport {

private static final long serialVersionUID = -4621492739125099197L;

private InstallService installService;

@Override

public String execute() throws Exception {

Calendar date = Calendar.getInstance();

date.set(Calendar.DAY_OF_MONTH, 3);

date.set(Calendar.HOUR_OF_DAY, 0);

date.set(Calendar.MINUTE, 0);

date.set(Calendar.SECOND, 0);

System.out.println(date.getTime());

System.out.println(JSON.toJSONString(installService.selectByPrimaryKey(date.getTime())));

return SUCCESS;

}

public InstallService getInstallService() {

return installService;

}

@Autowired

public void setInstallService(InstallService installService) {

this.installService = installService;

}

}

6.mybatis.xml和struts2.xml配置文件

mybaitis.xml

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>

<!-- 指定映射器路径 -->

<mappers>

<mapper resource="com/testStruts/mapping/FlowInstallTargetMapper.xml"/>

<mapper resource="com/testStruts/mapping/FlowSellTargetMapper.xml"/>

</mappers>

</configuration>

struts2.xml

<?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">

<struts>

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

<action name="installAction" class="com.testStruts.action.InstallAction">

<result name="success">success.jsp</result>

<result name="error">error.jsp</result>

</action>

</package>

</struts>

comfig.properties postgres数据库

hibernate.dialect=org.hibernate.dialect.PostgreSQLDialect

driverClassName=org.postgresql.Driver

validationQuery=SELECT 1

jdbc_url=jdbc:postgresql://*.*.*.*:5432/flowlog?characterEncoding=UTF8

jdbc_username=postgres

jdbc_password=

至此我们的整合就完成了，在spring的配置文件里面我对所有的bean做了手工配置，在class类里做了自动注入，有点多此一举，大概是抱着有备无患的想法。我是新手，勿喷，谢谢。
