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

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>
