SpringMVC + Spring + MyBatis + Maven多模块
SpringMVC + Spring + MyBatis
Maven多模块
项目地址:https://github.com/ryiann/ssm-parent
什么是SSM框架?
SpringMVC:
1.客户端发送请求到DispacherServlet(分发器)
2.由DispacherServlet控制器查询HanderMapping,找到处理请求的Controller
3.Controller调用业务逻辑处理后,返回ModelAndView
4.DispacherSerclet查询视图解析器,找到ModelAndView指定的视图
5.视图负责将结果显示到客户端Spring:
1.Spring是一个轻量级的控制反转(IOC)和面向切面(AOP)的容器架构,IOC容器包含并管理应用对象的配置和生命周期,你可以配置你的每个bean如何被创建,也可以配置每个bean是只有一个实例,还是每次需要时都生成一个新的实例,以及它们是如何相互关联的
2.IOC思想最核心的地方在于,资源不由使用资源的双方管理,而由不使用资源的第三方管理,这可以带来很多好处。第一,资源集中管理,实现资源的可配置和易管理。第二,降低了使用资源双方的依赖程度,也就是我们说的耦合度
3.容器提供了AOP技术,利用它很容易实现如权限拦截、运行期监控等功能
MyBatis:
1.MyBatis是支持普通SQL查询,存储过程和高级映射的优秀持久层框架。MyBatis消除了几乎所有的JDBC代码和参数的手工设置以及结果集的检索。MyBatis使用简单的XML或注解用于配置和原始映射,将接口和Java的POJOs(Plan
Old Java Objects,普通的Java对象)映射成数据库中的记录
2.MyBatis的操作都是围绕一个sqlSessionFactory实例展开的。MyBatis通过配置文件关联到各实体类的Mapper文件,Mapper文件中配置了每个类对数据库所需进行的sql语句映射。在每次与数据库交互时,通过sqlSessionFactory拿到一个sqlSession,再执行sql命令
为什么使用Maven多模块?
JavaEE项目开发中为了便于后期的维护,一般会进行分层开发,分层之后,各个层之间的职责会比较明确,后期维护起来也相对比较容易
项目结构
创建Maven多模块项目
一、创建ssm-parent项目
创建 ssm-parent,用来给各个子模块继承
使用 cmd 或者 Terminal,进入命令行,输入以下命令:
mvn archetype:generate
-DgroupId=com.ryan -DartifactId=ssm-parent -DarchetypeArtifactId=maven-archetype-quickstart
-DinteractiveMode=false |
命令执行完成之后可以看到在当前目录生成了ssm-parent目录,里面有一个src目录和一个 pom.xml文件,如下图所示:
将src文件夹删除,然后修改pom.xml文件,将<packaging>jar</packaging>修改为<packaging>pom</packaging>,pom表示它是一个被继承的模块,修改后的内容如下:
<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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.ryan</groupId> <artifactId>ssm-parent</artifactId>
<packaging>pom</packaging> <version>1.0-SNAPSHOT</version>
<name>ssm-parent</name> <url>http://maven.apache.org</url>
<dependencies> <dependency>
<groupId>junit</groupId> <artifactId>junit</artifactId>
<version>3.8.1</version> <scope>test</scope>
</dependency> </dependencies>
</project> |
注:
archetype:maven工程的模板工具包
mvn archetype:generate:创建项目(在maven 3.02以下的版本,使用archetype:create
命令创建)
DgroupId:组织ID
DartifactId:项目ID
DarchetypeArtifactId:工程类型
DinteractiveMode:是否已交互模式进行,如果是false的话就会采用默认设置建立项目
二、创建ssm-domain模块
命令行进入创建好的ssm-parent目录,然后执行下列命令:
mvn archetype:generate
-DgroupId=com.ryan -DartifactId=ssm-domain -DarchetypeArtifactId=maven-archetype-quickstart
-DinteractiveMode=false |
命令执行完成之后可以看到在ssm-parent目录中生成了ssm-domain,里面包含src目录和pom.xml文件。如下图所示:
修改ssm-domain目录中的pom.xml文件,把<groupId>com.ryan</groupId>和<version>1.0-SNAPSHOT</version>去掉,加上<packaging>jar</packaging>,因为groupId和version会继承ssm-parent中的groupId和version,packaging设置打包方式为jar,修改过后的pom.xml文件如下:
<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd"
xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.0.0</modelVersion>
<parent> <groupId>com.ryan</groupId>
<artifactId>ssm-parent</artifactId>
<version>1.0-SNAPSHOT</version>
</parent> <artifactId>ssm-domain</artifactId>
<packaging>jar</packaging> <name>ssm-domain</name>
<url>http://maven.apache.org</url>
<dependencies> <dependency>
<groupId>junit</groupId> <artifactId>junit</artifactId>
<version>3.8.1</version> <scope>test</scope>
</dependency> </dependencies>
</project> |
三、创建ssm-common模块
命令行进入创建好的ssm-parent目录,然后执行下列命令:
mvn archetype:generate
-DgroupId=com.ryan -DartifactId=ssm-common -DarchetypeArtifactId=maven-archetype-quickstart
-DinteractiveMode=false |
修改ssm-common目录中的pom.xml文件,把<groupId>com.ryan</groupId>和<version>1.0-SNAPSHOT</version>去掉,加上<packaging>jar</packaging>,因为groupId和version会继承ssm-parent中的groupId和version,packaging设置打包方式为jar,修改后的内容如下:
<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd"
xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.0.0</modelVersion>
<parent> <groupId>com.ryan</groupId>
<artifactId>ssm-parent</artifactId>
<version>1.0-SNAPSHOT</version>
</parent> <artifactId>ssm-common</artifactId>
<packaging>jar</packaging> <name>ssm-common</name>
<url>http://maven.apache.org</url>
<dependencies> <dependency>
<groupId>junit</groupId> <artifactId>junit</artifactId>
<version>3.8.1</version> <scope>test</scope>
</dependency> </dependencies>
</project> |
四、创建ssm-dao模块
命令行进入创建好的ssm-parent目录,然后执行下列命令:
mvn archetype:generate
-DgroupId=com.ryan -DartifactId=ssm-dao -DarchetypeArtifactId=maven-archetype-quickstart
-DinteractiveMode=false |
修改ssm-dao目录中的pom.xml文件,把<groupId>com.ryan</groupId>和<version>1.0-SNAPSHOT</version>去掉,加上<packaging>jar</packaging>,因为groupId和version会继承ssm-parent中的groupId和version,packaging设置打包方式为jar,同时添加对ssm-domain、ssm-common模块的依赖,修改后的内容如下:
<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd"
xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.0.0</modelVersion>
<parent> <groupId>com.ryan</groupId>
<artifactId>ssm-parent</artifactId>
<version>1.0-SNAPSHOT</version>
</parent> <artifactId>ssm-dao</artifactId>
<packaging>jar</packaging> <name>ssm-dao</name>
<url>http://maven.apache.org</url>
<dependencies> <dependency>
<groupId>junit</groupId> <artifactId>junit</artifactId>
<version>3.8.1</version> <scope>test</scope>
</dependency> <dependency>
<groupId>com.ryan</groupId> <artifactId>ssm-domain</artifactId>
<version>${project.version}</version>
</dependency> <dependency>
<groupId>com.ryan</groupId> <artifactId>ssm-common</artifactId>
<version>${project.version}</version>
</dependency> </dependencies>
</project> |
五、创建ssm-service模块
命令行进入创建好的ssm-parent目录,然后执行下列命令:
mvn archetype:generate
-DgroupId=com.ryan -DartifactId=ssm-service -DarchetypeArtifactId=maven-archetype-quickstart
-DinteractiveMode=false |
修改ssm-service目录中的pom.xml文件,把<groupId>com.ryan</groupId>和<version>1.0-SNAPSHOT</version>去掉,加上<packaging>jar</packaging>,因为groupId和version会继承ssm-parent中的groupId和version,packaging设置打包方式为jar,同时添加对ssm-dao模块的依赖,ssm-service依赖ssm-dao、ssm-domain和ssm-common,但是我们只需添加ssm-dao的依赖即可,因为ssm-dao已经依赖了ssm-domain、ssm-common。修改后的内容如下:
<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd"
xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.0.0</modelVersion>
<parent> <groupId>com.ryan</groupId>
<artifactId>ssm-parent</artifactId>
<version>1.0-SNAPSHOT</version>
</parent> <artifactId>ssm-service</artifactId>
<packaging>jar</packaging> <name>ssm-service</name>
<url>http://maven.apache.org</url>
<dependencies> <dependency>
<groupId>junit</groupId> <artifactId>junit</artifactId>
<version>3.8.1</version> <scope>test</scope>
</dependency> <dependency>
<groupId>com.ryan</groupId> <artifactId>ssm-dao</artifactId>
<version>${project.version}</version>
</dependency> </dependencies>
</project> |
六、创建ssm-web模块
命令行进入创建好的ssm-parent目录,然后执行下列命令:
mvn archetype:generate
-DgroupId=com.ryan -DartifactId=ssm-web -DarchetypeArtifactId=maven-archetype-webapp
-DinteractiveMode=false |
命令执行完成之后可以看到在ssm-parent目录中生成了ssm-web,里面包含src目录和pom.xml文件。如下图所示:
修改ssm-web目录中的pom.xml文件,把<groupId>com.ryan</groupId>和<version>1.0-SNAPSHOT</version>去掉,因为groupId和version会继承ssm-parent中的groupId和version,packaging设置打包方式为war,同时添加对ssm-service模块的依赖,修改后的内容如下:
<?xml version="1.0"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/xsd/maven-4.0.0.xsd"
xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<modelVersion>4.0.0</modelVersion>
<parent> <groupId>com.ryan</groupId>
<artifactId>ssm-parent</artifactId>
<version>1.0-SNAPSHOT</version>
</parent> <artifactId>ssm-web</artifactId>
<packaging>war</packaging> <name>ssm-web
Maven Webapp</name> <url>http://maven.apache.org</url>
<dependencies> <dependency>
<groupId>junit</groupId> <artifactId>junit</artifactId>
<version>3.8.1</version> <scope>test</scope>
</dependency> <dependency>
<groupId>com.ryan</groupId> <artifactId>ssm-service</artifactId>
<version>${project.version}</version>
</dependency> </dependencies>
<build> <finalName>ssm-web</finalName>
</build>
</project> |
至此,Maven多模块项目已经搭建完成!
SSM框架整合配置
我们使用的是maven来管理的jar,所以只需要在pom.xml中加入相应的依赖,就能导入需要的jar包。这里把项目用到的jar贴在下面,可以自己调整版本号。因为是多模块项目,每个子模块下面都有pom.xml,这里只举例ssm-service下的pom.xml,当然所有模块的依赖也可以都放在ssm-parent下的pom.xml(即父项目的pom.xml),可按照需要自行调整
ssm-service pom.xml

下面开始进行编写框架所需配置文件
参数配置文件
通常我们把数据库配置、redis等相关参数放到配置文件中,所以在ssm-web模块中的resources文件夹里新建applicationContext.properties文件,存放项目相关参数配置
#db
#jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.driver=com.mysql.jdbc.Driver
#jdbc.url=jdbc:oracle:thin:@172.18.100.223:1521:duvet
jdbc.url=jdbc:mysql://mysql.lqiao.top:3306/student?useUnicode =true&characterEncoding=utf8
jdbc.username=student
jdbc.password=Password@123456
pool.maxPoolSize=10
pool.removeAbandonedTimeout=180000
pool.maxWait=10000
pool.timeBetweenEvictionRunsMillis=60000
pool.minEvictableIdleTimeMillis=300000
pool.validationQuery=select 1 |
注:
配置中的数据库信息为测试库,只有select权限
连接池数据源配置文件
在ssm-web模块中的resources文件夹里新建dataSource.xml文件,配置连接池数据源
数据库连接信息
配置数据库连接池
声明式事务
配置SqlSessionFactory对象
扫描dao层接口,动态实现dao接口
dataSource.xml

其他配置
项目中还配置了日志、事务、线程池及Spring跳转配置,可根据实际情况斟酌增删配置
数据库脚本
这里贴上demo的数据库,并为student表初始化一些数据
SET NAMES utf8mb4;
SET FOREIGN_KEY_CHECKS = 0;
