• 【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

            配置切入点    指定这个aop:pointcut去引用上面规定的advice,也就是说规定下面的这个expression指定的路径下的service.impl下的所有的方法,都按照上面advice中的规定去执行,碰上什么操作,事务就是什么类型的,这就是事务管理器的好处了
            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
            指定在txAdvice切入点应用txAdvice事务增强处理
            <aop:advisor pointcut-ref="transactionPointcut"
                advice-ref="transactionAdvice" />
        </aop:config> -->
    
    </beans>

    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";
        }
    }
    View Code

    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

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
             xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
             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
    
             -->
            <display-name>aopExample</display-name>
            <!-- web容器,首先需要引入spring,让spring管理各个框架,并将其注入为bean -->
            <!-- 这个相当于定一个 变量在web.xml中,在下面的listener  org.springframework.web.context.ContextLoaderListener中,加载这个spring-hibernate.xml文件 -->

            <!-- 监听servletContext,启动contextConfigLocation中的spring配置信息 -->
            <listener>
                <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
            </listener>
    
    
            <!-- 防止spring内存溢出监听器   可用可不用-->

                <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
            </listener>
    
    
            <!-- 类似与servlet 需要在web.xml中都需要配置一样,spring的思想是让这些servlet【controller也是servlet】继承了一个基础的servlet,那就只需在web.xml中配置一个servlet即可。 -->
            <!-- 这个servlet和下面的servlet-mapping相配合使用,注明了所有的以.htmls结尾的请求都被截取到,去到servlet中去找相对应的方法 进行处理 -->
            <servlet>
