文章标签 idea通过maven构建模块 ssm maven IDEA spring 文章分类 架构后端开发

一、构建Maven项目

新建一个Maven项目，选择如图的maven-archetype-webapp，选择Next。

idea通过maven构建模块 idea用maven搭建ssm_IDEA

输入项目信息。GroupId为公司名称，ArtifactId为项目名。点击Next。

idea通过maven构建模块 idea用maven搭建ssm_idea通过maven构建模块_02

选择Maven目录，这里设置为我电脑上的maven位置。点击Next，然后直接Finish。

idea通过maven构建模块 idea用maven搭建ssm_spring_03

新建项目的目录结构如下：

idea通过maven构建模块 idea用maven搭建ssm_IDEA_04

此时需要我们手动创建maven项目的完整目录，创建完成后的目录结构如下：

idea通过maven构建模块 idea用maven搭建ssm_idea通过maven构建模块_05

至此，Maven项目构建完毕。

搭建ssm环境

修改pom.xml文件，添加需要的依赖

在spring目录下新建applicationContext-dao.xml，文件内容如下：

<beans xmlns="http://www.springframework.org/schema/beans"

        会导致数据源配置不管用，数据库连接不上。
        且spring 4弃用
        -->
    </bean>

</beans>

在spring目录下新建applicationContext-service.xml，内容如下：

<beans xmlns="http://www.springframework.org/schema/beans"

</beans>

在resources目录下新建文件夹mybatis，在mybatis目录下新建sqlMapConfig.xml，内容如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
		PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
		"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>

	<!-- 全局setting配置，根据需要添加 -->
	<settings>

	</settings>

	<!-- 配置别名 -->
	<typeAliases>
		<!-- 批量扫描别名 -->
		<package name="com.cose.demo.po"/>
	</typeAliases>

	<!-- 配置mapper
    由于使用spring和mybatis的整合包进行mapper扫描，这里不需要配置了。
    必须遵循：mapper.xml和mapper.java文件同名且在一个目录
     -->

</configuration>

在resources目录下新建jdbc.properties，用于配置mysql数据库连接的信息，内容如下：

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/demo
jdbc.username=root
jdbc.password=123456

在resources目录下新建log4j.properties，用于设置日志信息，此处日志打印要设为DEBUG，方便开发时查看详细的日志信息。该文件内容如下：

# Global logging configuration
log4j.rootLogger=DEBUG, stdout
# Console output...
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] - %m%n

至此，ssm环境也搭建完毕。
