00-A-springmvc分布式项目项目结构

项目使用IDEA进行开发

一个分布式项目基本需要的模块。

用到的技术spring+springmvc+mybatis+dubbo +mysql+redis

01模块名字：p2p-parent

作为父模块，对其他模块进行管理。

1，idea新建空项目，设置项目保存位置。

2，选择新建模块，选择maven项目类型，不选择具体的模板，建出来是一个有maven基本结构的项目，这个项目作为父模块，可以起名为：xxx(项目名)-parent。

3，修改配置文件，在配置文件添加节点packaging，文本内容为pom：

<packaging>pom</packaging>

4,删除src目录，parent项目不需要src目录。

5，配置文件内容：

02模块：p2p-common

存放工具类和常量类比如日期帮助类、项目中的一些常量

新建模块，继承自parent，项目模板可以选择maven的quickstart或者不选模板，建出来后具有maven项目基本结构。

com.bjpowernode.p2p 顶级包

com.bjpowernode.p2p.common.constant 存放常量

com.bjpowernode.p2p.common.util 存放工具和帮助类

这是一个很简单的模块，其他模块会依赖该模块。

pom.xml配置文件内容：

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

<project xmlns="http://maven.apache.org/POM/4.0.0"

         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <parent>

        <artifactId>p2p-parent</artifactId>

        <groupId>com.bjpowernode.p2p</groupId>

        <version>1.0.0</version>

        <relativePath>../p2p-parent/pom.xml</relativePath>

    </parent>

    <modelVersion>4.0.0</modelVersion>

    <artifactId>p2p-common</artifactId>

</project>

03模块名字：p2p-exterface

该模块是接口项目，新建模块的时候，需要继承自parent模块，同时选择继承GroupId。

选择模板，可以选择quickstart模板或者不选择模板。

dubbo推荐这种开发模式，该模板存放接口和bean、vo等。

com.bjpowernode.p2p 顶级包package

com.bjpowernode.p2p.model 存放bean的包，包名也可以是domain、beans等

com.bjpowernode.p2p.service 存放业务接口的包。

com.bjpowernode.p2p.vo 存放vo类（全称为Value Object,就是一个普通的JavaBean。一般配合DAO来使用，用于实例化对象。）

继承自parent模块，会在pom文件生成一段配置，这段配置如下，假如新建模块时没有继承自parent，可以直接在配置文件里面写上配置，达到一样的效果。

 <parent>

        <artifactId>p2p-parent</artifactId>

        <groupId>com.bjpowernode.p2p</groupId>

        <version>1.0.0</version>

        <relativePath>../p2p-parent/pom.xml</relativePath>

    </parent>

具体的配置文件内容：

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

            -->

            <scope>provided</scope>

        </dependency>

    </dependencies>

</project>

03模块：p2p-dataservice

该模块是dubbo服务提供者。

它要去实现p2p-exterface工程的业务接口,并连接数据库实现数据的持久层

新建模块，继承自parent，模板选择maven项目webapp

com.bjpowernode.p2p 顶级包

com.bjpowernode.p2p.mapper 存放dao接口和mybatis的xml映射文件的包

com.bjpowernode.p2p.service 存放exterface的Service中接口的实现类

resources中存放配置文件

applicationContext.xml 主要：加载系统配置文件配置扫描service包的注解导入数据库相关配置导入redis相关配置导入服务提供者配置

applicationContext-datasource.xml 主要：配置数据库连接，阿里数据源 druid 连接池 MyBatis sqlSessionFactory 配置 mybatis的MapperScannerConfigurer自动装配配置、事务控制等。

applicationContext-dubbo-provider.xml 主要：服务提供者应用名称，配置 zookeeper 注册中心暴露具体的业务服务

applicationContext-redis.xml 主要：jedis Connection Factory redis template definition

log4j2.xml 主要：log4j的日志配置

mybatis-configuration.xml 主要： log4j2 与 mybatis 集成，目的是打印出 sql 语句

redis.properties 主要：redis的连接数据。

WEB_INF配置文件：

web.xml 主要：spring 监听器加载 applicationContext.xml 配置文件 spring 字符过滤器

applicationContext.xml 配置文件内容：

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