spring+mybatis整合

前言

前面写了mybatis的数据库文件生成java文件和xml配置文件，现在开始最重要的spring+mybatis配置，以前没有人讲到每个jar拿做什么我就说说吧，因为不要乱加jar！！！烦

一、pom文件引入，具体介绍每个包的用途。没有一个多余jar，很难得哦！

二、进行整合测试

首先当然是写实现类的接口

0：配置spring文件与mybatis配置文件

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:context="http://www.springframework.org/schema/context"       xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop"       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/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd">    <!--配置文件properties-->    <context:property-placeholder location="classpath*:config/development.properties" />    <!-- 支持标注 --><context:annotation-config /><context:component-scan base-package="com.ycy">      <context:include-filter type="aspectj" expression="com.ycy.*" />   </context:component-scan>       <!--自动扫描service-->   <!--  <context:component-scan base-package="com.ycy">       <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>         <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Repository"/>    </context:component-scan> --><!--    <mvc:annotation-driven/>    <aop:aspectj-autoproxy />--></beans>

spring-mybatis.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:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsdhttp://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsdhttp://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd"><!-- JNDI方式配置数据源 --><!-- <bean id="dataSource" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiName" value="${jndiName}"></property> </bean> --><!-- 配置数据源 --><bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"><property name="driverClassName" value="${driverClassName}" /><property name="url" value="${jdbc_url}" /><property name="username" value="${jdbc_username}" /><property name="password" value="${jdbc_password}" /><!-- 初始化连接大小 --><property name="initialSize" value="0" /><!-- 连接池最大使用连接数量 --><property name="maxActive" value="20" /><!-- 连接池最大空闲 --><!--<property name="maxIdle" value="20" />--><!-- 连接池最小空闲 --><property name="minIdle" value="0" /><!-- 获取连接最大等待时间 --><property name="maxWait" value="60000" /><!-- <property name="poolPreparedStatements" value="true" /> <property name="maxPoolPreparedStatementPerConnectionSize" value="33" /> --><property name="validationQuery" value="${validationQuery}" /><property name="testOnBorrow" value="false" /><property name="testOnReturn" value="false" /><property name="testWhileIdle" value="true" /><!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 --><property name="timeBetweenEvictionRunsMillis" value="60000" /><!-- 配置一个连接在池中最小生存的时间，单位是毫秒 --><property name="minEvictableIdleTimeMillis" value="25200000" /><!-- 打开removeAbandoned功能 --><property name="removeAbandoned" value="true" /><!-- 1800秒，也就是30分钟 --><property name="removeAbandonedTimeout" value="1800" /><!-- 关闭abanded连接时输出错误日志 --><property name="logAbandoned" value="true" /><!-- 监控数据库 --><!-- <property name="filters" value="stat" /> --><property name="filters" value="mergeStat" /></bean><!-- myBatis文件 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"><property name="dataSource" ref="dataSource" /><!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 --><property name="mapperLocations" value="classpath:/mapping/*.xml" /></bean><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"><property name="basePackage" value="com.ycy.dao" /><property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /></bean><!-- 配置事务管理器 --><bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><property name="dataSource" ref="dataSource" /></bean><!-- 注解方式配置事物 --><!-- <tx:annotation-driven transaction-manager="transactionManager" /> --><!-- 拦截器方式配置事物 --><tx:advice id="transactionAdvice" transaction-manager="transactionManager"><tx:attributes><tx:method name="add*" propagation="REQUIRED" /><tx:method name="append*" propagation="REQUIRED" /><tx:method name="insert*" propagation="REQUIRED" /><tx:method name="save*" propagation="REQUIRED" /><tx:method name="update*" propagation="REQUIRED" /><tx:method name="modify*" propagation="REQUIRED" /><tx:method name="edit*" propagation="REQUIRED" /><tx:method name="delete*" propagation="REQUIRED" /><tx:method name="remove*" propagation="REQUIRED" /><tx:method name="repair" propagation="REQUIRED" /><tx:method name="delAndRepair" propagation="REQUIRED" /><tx:method name="get*" propagation="SUPPORTS" /><tx:method name="find*" propagation="SUPPORTS" /><tx:method name="load*" propagation="SUPPORTS" /><tx:method name="search*" propagation="SUPPORTS" /><tx:method name="datagrid*" propagation="SUPPORTS" /><tx:method name="*" propagation="SUPPORTS" /></tx:attributes></tx:advice><aop:config><aop:pointcut id="transactionPointcut" expression="execution(* com.ycy.service..*Impl.*(..))" /><aop:advisor pointcut-ref="transactionPointcut" advice-ref="transactionAdvice" /></aop:config><!-- 配置druid监控spring jdbc --><bean id="druid-stat-interceptor" class="com.alibaba.druid.support.spring.stat.DruidStatInterceptor"></bean><bean id="druid-stat-pointcut" class="org.springframework.aop.support.JdkRegexpMethodPointcut" scope="prototype"><property name="patterns"><list><value>com.ycy.service.*</value></list></property></bean><aop:config><aop:advisor advice-ref="druid-stat-interceptor" pointcut-ref="druid-stat-pointcut" /></aop:config></beans>

config文件development.properties

hibernate.dialect=org.hibernate.dialect.MySQLDialectdriverClassName=com.mysql.jdbc.DrivervalidationQuery=SELECT 1jdbc_url=jdbc:mysql://localhost:3306/ycydb?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNulljdbc_username=rootjdbc_password=123456

1、Userservice接口编写

package com.ycy.service;import com.ycy.model.UserAccount;/** * Created by Administrator on 2015/8/13 0013. */public interface Userservice {    public UserAccount getUserAccountById(Long userId);}

2、UserserviceImpl编写

注意提示：

package com.ycy.service.impl;import com.ycy.dao.UserAccountMapper;import com.ycy.model.UserAccount;import com.ycy.service.Userservice;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Service;/** * Created by Administrator on 2015/8/13 0013. */@Servicepublic class UserserviceImpl implements Userservice {    @Autowired    private UserAccountMapper userAccountMapper;    public UserAccount getUserAccountById(Long userId) {        return userAccountMapper.selectByPrimaryKey(userId);    }}

3、编写测试类TestMybatis

package com;import com.ycy.model.UserAccount;import com.ycy.service.Userservice;import org.junit.Test;import org.junit.runner.RunWith;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.test.context.ContextConfiguration;import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;/** * Created by Administrator on 2015/8/13 0013. */@RunWith(SpringJUnit4ClassRunner.class)@ContextConfiguration(locations = {"classpath*:spring/applicationContext.xml","classpath*:spring/spring-mybatis.xml"})public class TestMybatis { @Autowired private  Userservice userservice;    @Test    public  void  test1(){       UserAccount u= userservice.getUserAccountById(1l);        System.out.println(u.getName());    }}

最终测试结果：

重要提示：idea与Eclipse不同，它不能读取src下面java的里面的xml，一般你放到resources的文件夹里面classpath:是个读取到的，

否则需要如下配置（一般不建议啊）直接在bulid里面：

<build>
        <finalName>YiTang</finalName>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*Mapper.xml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>
                    <include>**/*.xml</include>
                    <include>**/*.properties</include>
                </includes>
            </resource>
        </resources>
    </build>

到此mybatis与spring整合完毕，测试完毕。下一步整合mvc。。。。。主要的
