布满荆棘的人生 2023-10-12 18:07 99阅读 0赞

### 一、**整合思路** ###

**SSM介绍**  
 springmvc\+ spring \+ mybatis=ssm  
 mybatis 持久层的CRUD  
 spring 业务层 IOC、DI(解耦) 和AOP(事务问题、日志问题)  
 springMVC 表现层 MVC的操作

### 二、整合 ###

##### 1.导入依赖 #####

a、
    <dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>3.4.5</version>
    </dependency>
    
    <dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>8.0.31</version>
    </dependency>
    
    <dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>druid</artifactId>
    <version>1.2.16</version>
    </dependency>
    
    </dependency>
    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
    <version>5.0.2.RELEASE</version>
    </dependency>
    
    <dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    </dependency>
    
    
    <dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis-spring</artifactId>
    <version>1.3.1</version>
    </dependency>
    
    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>5.0.2.RELEASE</version>
    </dependency>
    
    
    <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-tx</artifactId>
    <version>5.0.2.RELEASE</version>
    </dependency>
    
    <dependency>
    <groupId>org.aspectj</groupId>
    <artifactId>aspectjweaver</artifactId>
    <version>1.8.9</version>
    </dependency>

##### 2.**整合Spring和Mybatis的配置文件** #####

**spring.xml**

<context:annotation-config></context:annotation-config>
    
    <context:component-scan base-package="com.sram"/>
     <context:property-placeholder location="classpath:jdbc_config.properties"/>
     <bean id="dataSource"
          class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
        <property name="url" value="jdbc:mysql:///test"></property>
        <property name="username" value="root"></property>
        <property name="password" value="root"></property>
    </bean>
    
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        
        <property name="dataSource" ref="dataSource"></property>
    </bean>
    
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        
        <property name="basePackage" value="com.sram.dao"></property>
    </bean>
    
     <bean id="transactionManager"
           class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
         <property name="dataSource" ref="dataSource"></property>
     </bean>
     
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
         
         <tx:attributes>
    
            <tx:method name="*" read-only="false" propagation="REQUIRED"/>
             <tx:method name="find*" read-only="true" propagation="SUPPORTS"/>
         </tx:attributes>
    
     </tx:advice>
     
     <aop:config>
         
         <aop:pointcut expression="execution(* com.sram.service..*.*(..))" id="pt1"/>
         
        <aop:advisor advice-ref="txAdvice" pointcut-ref="pt1"/>
     </aop:config>

##### 3.整合SpringMVC #####

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>5.0.2.RELEASE</version>
    </dependency>
    
    <dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
    </dependency>
    <dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jsp-api</artifactId>
    <version>2.0</version>
    <scope>provided</scope>
    </dependency>
    
      
          
          
          
      
    <dependency>

    </dependency>
      <dependency>
          <groupId>taglibs</groupId>
          <artifactId>standard</artifactId>
          <version>1.1.2</version>
      </dependency>

##### 4.springMVC.xml #####
