ssm框架项目整合

项目结构:

 

 项目采用Spring + Spring mvc + mybatis框架开发,数据库使用的是mysql

  controller:存放处理请求的handler类

  dao:存放表数据操作类

  db: 存放mybatis相关操作类和分页工具类

  entity:存放请求处理返回的实体类对象

  mapper:存放表mapper映射类

  operation:存放自定义操作方法类

  pojo :存放表对应的实体

  service:存放表业务逻辑服务类

  utils:存放工具类

 

 表映射xml文件,需要存放到resources目录下面,结构与java目录中的mapper保持一致

    <artifactId>commons-beanutils</artifactId>
    <version>1.9.3</version>

</dependency>

  <artifactId>quartz</artifactId>
  <version>1.8.5</version>
</dependency>

2、新建db.properties和log4j.properties文件

  db.properties文件内容,配置数据库信息

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

 log4j.properties文件内容,配置日志信息

# Global logging configuration\uff0c\u5efa\u8bae\u5f00\u53d1\u73af\u5883\u4e2d\u8981\u7528debug
log4j.rootLogger=INFO, 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

3、新建applicationContext.xml文件

   

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	   xmlns:aop="http://www.springframework.org/schema/aop"
	   xmlns:tx="http://www.springframework.org/schema/tx"
	   xmlns:context="http://www.springframework.org/schema/context"
	   xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context.xsd">
		
		<!-- 加载配置文件 -->
	<context:property-placeholder location="classpath:db.properties" />
	<!--配置数据源信息-->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="driverClass" value="${jdbc.driver}"></property>
		<property name="jdbcUrl" value="${jdbc.url}"></property>
		<property name="user" value="${jdbc.username}"></property>
		<property name="password" value="${jdbc.password}"></property>
	</bean>


	<!-- SqlsessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- 数据源 -->		<property name="dataSource" ref="dataSource"/>
		<!-- mybatis配置文件 -->
		<property name="configLocation" value="classpath:SqlMapConfig.xml"/>
	</bean>
	
	<!-- 
	MapperScannerConfigurer:mapper的扫描器,将包下边的mapper接口自动创建代理对象,
	自动创建到spring容器中,bean的id是mapper的类名(首字母小写)
	 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<!-- 配置扫描包的路径
		如果要扫描多个包,中间使用半角逗号分隔
		 -->
		<property name="basePackage" value="com.yzs.mapper"/>
		<!-- 使用sqlSessionFactoryBeanName -->
		<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
	</bean>
	
	<!-- 此文件为spring配置文件的扫描 -->
    <bean class="com.yzs.utils.SpringContextUtil" lazy-init="false"/>


	<!-- 1、配置处理器映射器 springmvc框架根据HandlerMapping接口判断是否是处理器映射器 -->
	<bean
		class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping" />

	<!-- 注解处理器映射器 -->
	<bean
		class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"></bean>


	<!-- 2、配置处理器适配器 springmvc框架根据HandlerAdapter接口判断是否是处理器适配器 -->
	<bean
		class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter" />

	<!-- HttpRequestHandlerAdapter适配器 -->
	<bean class="org.springframework.web.servlet.mvc.HttpRequestHandlerAdapter" />

	<!-- 4、配置视图解析器 要求将jstl的包加到classpath 
	  modelAndView.setViewName设置的视图名称,会在/WEB-INF/jsp/下面去找对应的jsp文件(视图名称等于jsp文件名称)
	-->
	<!-- ViewResolver -->
	<bean
		class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<!-- <property name="prefix" value="/WEB-INF/jsp/" />
		<property name="suffix" value=".jsp" /> -->
	</bean>


</beans>

4、新建mybatis框架核心配置文件SqlMapConfig.xml

      

<?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>
	<!-- 2、定义 别名 -->
	<typeAliases>
		<!-- 配置单个别名 -->
		<!-- <typeAlias type="com.yzs.pojo.Op_userinfo" alias="user"/> -->
		<!-- 批量别名定义 指定包路径,自动扫描包下边的pojo,定义别名,别名默认为类名(首字母小写或大写)-->
		<package name="com.yzs.pojo"/>
	</typeAliases>
</configuration>

 项目截图,项目是一个基础项目,可以在这个上面进一步开发管理系统
