创建maven多模块项目及ssm整合

Ssm+maven+freemarker搭建

1. 用maven创建多模块项目

 

1.整个项目的结构

 

 

|-- handsome

|--handsome-biz

|--handsome-biz-dao 数据库层

|--handsome-biz-manager 业务层

|--handsome-web

|--handsome-web-deploy 页面模板

|--handsome-web-home 控制层

|--handsome-web-war 用来运行,打包

 

 

 

 

2.首先创建一个maven项目

 

 

 

 

修改pom.xml文件

<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">

  <modelVersion>4.0.0</modelVersion>

 

  <groupId>com.handsome</groupId>

  <artifactId>handsome</artifactId>

  <version>0.0.1-SNAPSHOT</version>

  <packaging>pom</packaging>

 

  <name>handsome</name>

  <url>http://maven.apache.org</url>

 

  <properties>

    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

  </properties>

 

  <dependencies>

    <dependency>

      <groupId>junit</groupId>

      <artifactId>junit</artifactId>

      <version>3.8.1</version>

      <scope>test</scope>

    </dependency>

  </dependencies>

</project>

 

 

接下来创建的都是该项目的模块:

我理解的模块是分级的.在本项目中分为两级handsome-biz 和handsome-web是一级.其他为二级模块

3.创建一级模块handsome-biz和handsome-web

在handsome项目上新建模块

 

 

 

 

 

完成后在handsome中pom.xml文件中可以看到,两个子模块

 

修改两个一级模块的pom.xml文件的package为 pom准备创建二级模块

 

将红框中不需要的删除, 新增packaing标签

 

4.创建二级模块

在handsome-biz 和 handsome-web下创建 二级模块

创建方法和上面一样.不在复述..

 

5.删除一些不要的目录和依赖

 

父项目不要依赖. 吧dependencies标签干掉 左侧maven dependencies 目录就没有了.

Handsome 删成这样

 

其他两个一级模块也删到这样简洁.

 

 

6.添加模块之间的依赖关系

在handsome-biz-manager中添加对handsome-biz-dao的依赖

 

在handsome-web-core中添加对handsome-biz-manager的依赖

在handsome-web-war中添加对handsome-web-core的依赖

 

最终项目就变成了这样:

 

 

 

 

 

2.ssm整合

 

 

 

 

1.将war项目转换成web项目

 

这样项目就可以添加到tomcat了

 

部署的少了依赖包 

 

2.增加maven依赖到部署

 

 

3.修改整理pom文件

4.编译项目

在上选择 maven install

 

 

如果有错,, 整项目部署目录和web.xml文件

 

完成后可以看到tomcat中的变化

 

依赖包出现了.

 

 

5.整合思路

 

6.写一个简单功能代码

写一个简单功能代码. 从dao到manager(service) 到controller

Dao层   新建userdao,userdo

 

 

 

 

 

 

Manager层

 

 

 

 

Controller层 也就是handsome-web-core模块

 

 

 

 

Handsome-web-deploy  

 

 

 

 

上面详细的列出了项目结构和具体代码

 

 

7.具体配置

8.部署运行

 

部署tomcat运行后

 

如果发现少依赖, 需要检查 模块间依赖关系 和部署目录配置

 

 

模块间的依赖关系认真阅读上面关于pom文件 就可以解决

部署目录配置:

 

 

运行后的访问路径就不介绍了.

 

 

 

3.整合log4j

确保项目中已有log4j 依赖包

 

在web.xml文件中增加配置

 

 

 

在web-inf目录下新增配置文件log4j.xml

 

Log4j.xml

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

<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

<appender-ref ref="ALL" />

<appender-ref ref="CONSOLE" />

</root>

</log4j:configuration>

 

 

在war模块config.properties文件中增加两个变量

 

 

 

重新启动项目就可以看到日志了. 通过配置config.properties 中  level和root  就可以修改日志路径和日志级别了

 

 

 

 

 

4.值得注意的问题:

<context:property-placeholder location="classpath:config/config.properties" ignore-unresolvable="true"/>  加载properties文件后不能使用文件中定义的变量

java.lang.IllegalArgumentException: Could not resolve placeholder 'handsome.freemarker.templates' in string value "file://${handsome.freemarker.templates}"

 

解决方法:

原因:

Spring容器采用反射扫描的发现机制，在探测到Spring容器中有一个org.springframework.beans.factory.config.PropertyPlaceholderConfigurer的Bean就会停止对剩余PropertyPlaceholderConfigurer的扫描（Spring 3.1已经使用PropertySourcesPlaceholderConfigurer替代PropertyPlaceholderConfigurer了）。 
而<context:property-placeholder/>这个基于命名空间的配置，其实内部就是创建一个PropertyPlaceholderConfigurer Bean而已。换句话说，即Spring容器仅允许最多定义一个PropertyPlaceholderConfigurer(或<context:property-placeholder/>)，其余的会被Spring忽略掉（其实Spring如果提供一个警告就好了）。

在项目中每个<context:property-placeholder 标签加上 ignore-unresolvable="true"属性

 

 

Maven中packaging类型

任何一个Maven项目都需要定义POM元素packaging（如果不写则默认值为jar）。顾名思义，该元素决定了项目的打包方式。实际的情形中，如果你不声明该元素，Maven会帮你生成一个JAR包；如果你定义该元素的值为war，那你会得到一个WAR包；如果定义其值为POM（比如是一个父模块），那什么包都不会生成
