maven中的操作

<properties>
            
            <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
            <maven.compiler.source>1.7</maven.compiler.source>
            <maven.compiler.target>1.7</maven.compiler.target>
            <spring.version>5.1.5.RELEASE</spring.version>
            
        </properties>
    —————————————————————————————
      <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context</artifactId>
                <version>${spring.version}</version>
                
            </dependency>

需要的jar：

数据数据源c3p0

Spring包

mybatis包

xml配置：注意Spring的xml文件不要和mybatis的xml文件放在一起

这里的配置是最最重要的因为 相关操作依赖都在这里面配置

<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context"
           xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
           xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
        
        <context:annotation-config></context:annotation-config>
        <context:component-scan base-package="com.sun.SpringAndMybatis"></context:component-scan>
    
        
        <tx:annotation-driven proxy-target-class="true" transaction-manager="transactionManager"/>
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
            <property name="dataSource" ref="dataSource"></property>
        </bean>
    
        
        <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
            <property name="driverClass" value="com.mysql.jdbc.Driver"/>
            <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/test2?useUnicode=true&
                    characterEncoding=UTF-8&useSSL=false"/>
            <property name="user" value="root"/>
            <property name="password" value="Sb1996350."/>
            <property name="maxPoolSize" value="3"/>
            <property name="minPoolSize" value="1"/>
        </bean>
    
        
        <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
            <property name="dataSource" ref="dataSource"/>
            
            
            
            <property name="mapperLocations" value="classpath:mybatis/*.xml"></property>
        </bean>
    
        
        <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
            
            <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory">
                
            </property>
            <property name="basePackage" value="com.sun.SpringAndMybatis.Dao"/>
        </bean>
    </beans>

其余操作就跟mybatis操作是一样的

package com.sun.SpringAndMybatis;
    
    import com.sun.SpringAndMybatis.Dao.Stu;
    import org.springframework.context.ApplicationContext;
    import org.springframework.context.support.ClassPathXmlApplicationContext;
    
    public class Test2 {
    
    
        public static void main(String[] args) {
    
            ApplicationContext applicationContext = new ClassPathXmlApplicationContext("app.xml");
            Test test = applicationContext.getBean(Test.class);
            Stu stu = test.Select(5);
            System.out.println(stu.toString());
        }
    }

@Component
    @Transactional
    public class Test {
        @Autowired
        private StuMapper stuMapper;//引用接口 通过标记将对象赋值给他
    
        public void rgeUser(Integer sid, String sname, String address) {
            Stu stu = new Stu();
            stu.setAddress(address);
            stu.setSname(sname);
            stuMapper.insertSelective(stu);
        }
    
        public Stu Select(Integer sid) {
            Stu stu = stuMapper.selectByPrimaryKey(sid);
            return stu;
        }
    }
