【IntelliJ Idea】idea快速创建maven spring项目

想试试AOP在spring的web项目上的使用情况,所以想尽快使用idea快速的搭建一个spring的web项目,当然,是maven管理的项目

 

步骤如下:

 1。打开idea 左上角file--->new  --->project

2。选择Maven项目

好了,生成出来是下面这个狗样子

3.好了,新建web相关目录

建完把webapp目录设置成web的根目录,并且将web生成的web.xml文件放在WEB-INF位置下,往下看,操作就行

完了就是下面的狗样子

 

4.完善pom.xml文件

如果你是用的默认的maven本地仓库,也就是在本地的C:\Users\自己PC的用户名\.m2下的仓库的话,就不用更改什么,直接完善pom.xml文件。

如果你使用了自定义的maven仓库,那需要先设置一下本项目所作用的maven的setting.xml文件。

 

 然后完善pom.xml文件:

 5.接下来,是各个配置文件的配置,之前有在myecplise上配置过,配置是一样的

可以参考:【http://www.cnblogs.com/sxdcgaq8080/p/5606827.html】

 再resources目录下,分别创建如下文件:

config.properties

#jdbc c3p0 config
jdbc.driver = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/orderdiscount?useUnicode=true&characterEncoding=utf-8
jdbc.username = root
jdbc.password = root

#hibernate config
hibernate.dialect = org.hibernate.dialect.MySQLDialect
hibernate.show_sql = true
hibernate.format_sql = false
hibernate.hbm2ddl.auto = update
hibernate.cache.use_second_level_cache = true
hibernate.cache.use_query_cache = true
hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.EhCacheRegionFactory
hibernate.cache.provider_configuration_file_resource_path =ehcache.xml

        解释一下,为什么这个要指定在service层:因为在同一个事务中,可能要对多张表进行多个不同的操作,才是一个完整的逻辑,例如淘宝上买东西,你转账之后你的钱减少了,对方的钱应该增加了,这两个操作在一起才是一个完整的操作,而如果这两个操作不在一个事务中,也就是如果将事务的操作指定在Dao层【MVC的设计模式:Dao层就是对数据库进行最简单的增删改查操作,而service层是进行逻辑处理的,一个完整的逻辑处理就要涉及到多次操作】事务操作失败,发生回滚,那你的帐减少了,对方的帐并没有增加,这样就不美丽的,因此,将事务的管理,指定在了service层
        <aop:pointcut id="transactionPointcut"
            expression="execution(* com.it.service..*Impl.*(..))" />expression中表达式所指意思: 所有的文件下的 com.it.service开头的包,以Impl结尾的类下的所有的方法,都执行上面advice的规定

6.完善java中的包controller,并建立一个页面跳转MainController.java

MainController.java

package com.sxd.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
public class MainController {

    @ResponseBody
    @RequestMapping("do")
    public String doSomething(){
        return "Just  for  what";
    }
}

7.最恶心的一步,也是不同与ecplise的步骤,为本项目部署一个Tomcat

 

选上自己的项目即可

 

 

 

8.最后一步,完善web.xml文件

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         version="3.1">

        <!-- web容器是web项目的大脑 -->
        <!-- 在web.xml中,执行顺序是:1.先执行listener 2。再执行filter  3.最后执行servlet 这就是执行顺序
            就像spring-hibernate.xml文件是在执行Listener的时候加载的,那注意这几个配置文件在web.xml中的加载顺序,因为资源文件是在配置文件【xml文件】中加载的,肯定是先加载的资源文件【properties文件】,才能在配置文件中调用资源文件中的变量的值使用
