最近刚入职,发现公司都是使用eclipse,之前一直在学校一直使用netbeans集成开发环境,对eclipse不是太熟悉,自己也不太喜欢使用myeclipse收费的软件(虽然可以盗版激活),反应慢也是myeclipse被人诟病的原因,决定花一天时间来自己动手搭建eclipse+maven+spring。
准备工作:
1.下载eclipse(Eclipse Java EE IDE for Web Developers,Version: Juno Service Release 2)。
2.下载maven3.3.3。
3.安装maven插件()。
注意事项:maven3.3.3支持jdk1.7,maven3.2.5仅仅支持到1.6。
第一步:新建maven项目,选择Maven Project,如图1。
第二步:配置转换项目为spring项目。
首先右击项目,点击Properties,选择左边的java build path,我们先把出问题的删除,如果不删除,后面在新建source file时无法新建,如图,选择remove就行了。
新建src/main/java、src/test/java/、src/test/resources,如图,提示:如果你eclipse是选择java模式,可以直接新建source file,j2ee模式可以切换到java模式。
修改jdk版本,如果此版本不修改,会造成maven与jdk不兼容,导致编译出问题,右击JRE System Library[J2SE-1.5] 修改问1.7,如图。
你可以调整source folder的顺序,根据自己的喜好,我不知道有什么影响,看到有的教程上有调整的,如果你有强迫症,可以修改一下顺序,如图。
下面,我们解决最重要的一个步骤,spring项目的雏形就在这里显现, 把项目转化为web项目,先找到位置,如图。
点击Convert to faceted form... (注释:有的教程修改Further configuration available...,其实一般默认就可以,不用可以修改,我的eclipse就选的默认的,没修改),在右边选择你项目运行的应用服务器,我选的是tomcat 7.0,你选的maven 和tomcat与你的jdk有很的关系,现在虽然8出来了,单是选择1.7较为稳定,只是建议,根据个人喜好。
现在就转化为了web项目,我们在配置其他的东西,完成整个项目 。
现在的目录结构为这种情况,如图:
第三步:转化为spring项目,添加applicationContext.xml、simple-servlet.xml,配置spring文件,配置spring引用包即确定引用文件pom.xml。
applicationContext.xml 、demo-servlet.xml、web.xml为spring配置文件,demo-servlet.xml为配置转发器,主要作用与view层,applicationContext.xml主要配置数据库与事务,在这里不过多讲解,单是这两个文件一定要搞清楚怎么配置,每个配置模块什么意思,不求甚解会害惨自己,出个问题,找不到原因,我就曾经在这个地方吃过亏。对于pom.xml文件,我建议大家整理出一个自己需要的版本,之前大家不使用maven的时候,都是整理自己一个完整的lib包,maven的作用就是替大家管理引用文件,pom.xml文件就是配置需要引入的包,你项目依赖哪些包,就在这些pom.xml文件里引用,maven会帮你下载。下面依次列出每个文件的内容。
demo-servlet.xml

配置一下项目依赖关系,如图,remove右边红色框里面的内容,部署不需要把test文件部署上去,是不是???毋庸置疑。
再Add如下文件,如图:
不知道你们发现吗?现在项目还是红叉+s,那是因为我们还有一个地方没有修改,如图:
当我们配置好之后,项目又有可能自动改回来,看看之前是不是我们选择过jdk版本,但是现在又改了一次,那是因为还有个地方捣鬼,我当时就吃亏到到这个地方,浪费了好几十分钟思考,结果还是不如谷歌,哦,又想起一点,谷歌不是被封了,用这个"谷粉http://www.jwss.com/" ,也是谷歌的引擎。修改下图配置,java编译器:
此刻,我们神奇的发现,是不是在maven依赖包里出现了如下美好画面:
至此,项目配置文件搞定,下面我们添加示例代码演示maven神奇之处。
第五步:测试项目。我们只写一个拦截器,来测试一下。
新建一个jsp文件夹,如图:
在controller报中,我们新建一个java类HomeController,添加如下代码:
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import com.demo.dao.HomeServcies;
@Controller
public class HomeController {
@Autowired
HomeServcies homeServcies;
@RequestMapping(value = "index")
public String Index() {
return "/jsp/index";
}
}
测试运行:
出现神奇的,如图:
到此,结束了。
刚来北京,没有钱,只能撸代码玩了。
