Spring+myBatis3

1.数据库表创建

CREATE TABLE `name` (  `id` bigint(20) NOT NULL COMMENT '主键ID',  `name` bigint(20) DEFAULT NULL,  PRIMARY KEY (`id`)) ENGINE=InnoDB DEFAULT CHARSET=latin1   |

mysql> select * from name;+----+------+| id | name |+----+------+|  1 |    1 |+----+------+

2.项目目录结构

3.编写 mybatis generator 插件需要的配置文件

该配置文件详解:http://blog.csdn.net/isea533/article/details/42102297

src/main/resources 下 ,创建 generatorConfig.xml文件

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE generatorConfiguration        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"><generatorConfiguration><!-- 如果classpath没有jar,就需要指定 --><classPathEntrylocation="/Users/baidu/Desktop/mysql-connector-java-5.1.38-bin.jar" /><context id="my" targetRuntime="MyBatis3" defaultModelType="flat"><commentGenerator><property name="suppressDate" value="true" /><property name="suppressAllComments" value="true" /></commentGenerator><jdbcConnection driverClass="com.mysql.jdbc.Driver"connectionURL="jdbc:mysql://localhost:3306/test" userId="" password="" /><!-- 实体类 targetProject=工程名/包路径 --><javaModelGenerator targetPackage="com.baidu.test.entry"targetProject="mybatisdemo/src/main/java"><property name="enableSubPackages" value="true" /><property name="trimStrings" value="true" /></javaModelGenerator><!-- sql mappper.xml --><sqlMapGenerator targetPackage="com.baidu.test.dao"targetProject="mybatisdemo/src/main/resources"><property name="enableSubPackages" value="true" /></sqlMapGenerator><!-- sql mapper.java --><javaClientGenerator targetPackage="com.baidu.test.dao"targetProject="mybatisdemo/src/main/java" type="XMLMAPPER"><property name="enableSubPackages" value="true" /></javaClientGenerator><!-- 逆向工程的表名称 %通配符全部表 --><table tableName="name" enableCountByExample="false" enableUpdateByExample="false"enableDeleteByExample="false" enableSelectByExample="false"selectByExampleQueryId="false"></table></context></generatorConfiguration>

4.运行插件,生成对应的 javabean,dao,mapper.xml文件

5.pom.xml引用需要的配置信息.

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.baidu.lbc</groupId><artifactId>mybatisdemo</artifactId><packaging>war</packaging><version>0.0.1-SNAPSHOT</version><name>mybatisdemo Maven Webapp</name><url>http://maven.apache.org</url><properties>        <!-- spring版本号 -->        <spring.version>3.2.4.RELEASE</spring.version>        <!-- mybatis版本号 -->        <mybatis.version>3.2.4</mybatis.version>        <!-- log4j日志文件管理包版本 -->        <slf4j.version>1.6.6</slf4j.version>        <log4j.version>1.2.9</log4j.version>    </properties>    <dependencies>        <!-- spring核心包 -->        <!-- springframe start -->        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-core</artifactId>            <version>${spring.version}</version>        </dependency>         <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-web</artifactId>            <version>${spring.version}</version>        </dependency>         <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-oxm</artifactId>            <version>${spring.version}</version>        </dependency>         <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-tx</artifactId>            <version>${spring.version}</version>        </dependency>         <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-jdbc</artifactId>            <version>${spring.version}</version>        </dependency>         <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-webmvc</artifactId>            <version>${spring.version}</version>        </dependency>         <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-aop</artifactId>            <version>${spring.version}</version>        </dependency>         <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-context-support</artifactId>            <version>${spring.version}</version>        </dependency>         <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-aop</artifactId>            <version>${spring.version}</version>        </dependency>         <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-test</artifactId>            <version>${spring.version}</version>        </dependency>        <!-- springframe end -->         <!-- mybatis核心包 -->        <dependency>            <groupId>org.mybatis</groupId>            <artifactId>mybatis</artifactId>            <version>${mybatis.version}</version>        </dependency>        <!-- mybatis/spring包 -->        <dependency>            <groupId>org.mybatis</groupId>            <artifactId>mybatis-spring</artifactId>            <version>1.2.2</version>        </dependency>        <!-- mysql驱动包 -->        <dependency>            <groupId>mysql</groupId>            <artifactId>mysql-connector-java</artifactId>            <version>5.1.29</version>        </dependency>        <!-- junit测试包 -->        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <version>4.11</version>            <scope>test</scope>        </dependency>        <!-- 阿里巴巴数据源包 -->        <dependency>            <groupId>com.alibaba</groupId>            <artifactId>druid</artifactId>            <version>1.0.2</version>        </dependency>         <!-- json数据 -->        <dependency>            <groupId>org.codehaus.jackson</groupId>            <artifactId>jackson-mapper-asl</artifactId>            <version>1.9.13</version>        </dependency>         <!-- 日志文件管理包 -->        <!-- log start -->        <dependency>            <groupId>log4j</groupId>            <artifactId>log4j</artifactId>            <version>${log4j.version}</version>        </dependency>        <dependency>            <groupId>org.slf4j</groupId>            <artifactId>slf4j-api</artifactId>            <version>${slf4j.version}</version>        </dependency>        <dependency>            <groupId>org.slf4j</groupId>            <artifactId>slf4j-log4j12</artifactId>            <version>${slf4j.version}</version>        </dependency>        <!-- log end -->    </dependencies><build><finalName>spring4-mybatis3</finalName></build></project>

6. 将jdbc连接信息写成properties文件

src/main/resource/dbconfig.properties

jdbc_driverClassName=com.mysql.jdbc.Driverjdbc_url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNulljdbc_username=jdbc_password=

7.编写spring配置文件

src/main/resource/spring.xml

<?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"    xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-3.0.xsdhttp://www.springframework.org/schema/contexthttp://www.springframework.org/schema/context/spring-context-3.0.xsd" default-autowire="byName">    <!-- 引入dbconfig.properties属性文件 -->    <context:property-placeholder location="classpath:dbconfig.properties" />    <!-- 自动扫描(自动注入)，扫描me.gacl.service这个包以及它的子包的所有使用@Service注解标注的类 -->    <context:component-scan base-package="com.baidu.test.service" /></beans>

8. spring和mybatis连接配置

src/main/resource/spring-mybatis.xml

<?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"xmlns:util="http://www.springframework.org/schema/util"xsi:schemaLocation="http://www.springframework.org/schema/beans    http://www.springframework.org/schema/beans/spring-beans-3.2.xsd    http://www.springframework.org/schema/context    http://www.springframework.org/schema/context/spring-context-3.2.xsd    http://www.springframework.org/schema/tx    http://www.springframework.org/schema/tx/spring-tx-3.2.xsd    http://www.springframework.org/schema/aop    http://www.springframework.org/schema/aop/spring-aop-3.2.xsd    http://www.springframework.org/schema/util     http://www.springframework.org/schema/util/spring-util-3.2.xsd"><bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"init-method="init" destroy-method="close"><property name="driverClassName"><value>${jdbc_driverClassName}</value></property><property name="url"><value>${jdbc_url}</value></property><property name="username"><value>${jdbc_username}</value></property><property name="password"><value>${jdbc_password}</value></property><!-- 连接池最大使用连接数 --><property name="maxActive"><value>20</value></property><!-- 初始化连接大小 --><property name="initialSize"><value>1</value></property><!-- 获取连接最大等待时间 --><property name="maxWait"><value>60000</value></property><!-- 连接池最大空闲 --><property name="maxIdle"><value>20</value></property><!-- 连接池最小空闲 --><property name="minIdle"><value>3</value></property><!-- 自动清除无用连接 --><property name="removeAbandoned"><value>true</value></property><!-- 清除无用连接的等待时间 --><property name="removeAbandonedTimeout"><value>180</value></property><!-- 连接属性 --><property name="connectionProperties"><value>clientEncoding=UTF-8</value></property></bean><!-- mybatis文件配置，扫描所有mapper文件 --><bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"p:dataSource-ref="dataSource" p:configLocation="classpath:mybatis-config.xml"p:mapperLocations="classpath:com.baidu.test.dao.*.xml" /><!-- spring与mybatis整合配置，扫描所有dao --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"p:basePackage="com.baidu.test.dao" p:sqlSessionFactoryBeanName="sqlSessionFactory" /><!-- 对数据源进行事务管理 --><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"p:dataSource-ref="dataSource" /></beans>

9. 编写service层代码,@Service注解注到impl上.使用@Autowired注入dao层接口.

10.mybatis基本配置

src/main/resource/mybaits-config.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><!-- 命名空间 --><typeAliases><typeAlias alias="Name" type="com.baidu.test.entry.Name" /></typeAliases><!-- 映射map --><mappers></mappers></configuration>

11.junit

package mybatisdemo;import org.junit.Before;import org.junit.Test;import org.springframework.context.support.ClassPathXmlApplicationContext;import com.baidu.test.entry.Name;import com.baidu.test.service.Record;import com.baidu.test.service.impl.RecordImpl;public class RecordTesrt {    private Record record;    @Before    public void before() {        ClassPathXmlApplicationContext context = new ClassPathXmlApplicationContext(                new String[] { "classpath:spring.xml", "spring-mybatis.xml" });        record = (RecordImpl) context.getBean("recordImpl");    }    @Test    public void testRecordImpl() {        Name name = new Name();        name.setId(2L);        name.setName(1L);        record.insertName(name);    }}

12.不出意外,应该绿了才对

数据库应该也有数据了
