SM框架整合

1      使用idea创建一个maven webapp项目

 

 

 

 

 

 

 

 

 

到此为止项目初步建立，需要等待maven对项目结构进行组织，直到状态栏的进度条完成，且项目的目录结构如下：

 

 

2      因为是SSM，需要操作数据库，现在准备数据以及表，此处选择mysql数据库

2.1   准备表

-- auto-generated definition create table student ( ID int auto_increment primary key, stuName varchar(32) null, stuAge tinyint null, mobile varchar(11) null, address varchar(256) null, EntranceTime date null ) ;

 

2.2   准备初始化数据

INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('何靖', 8, '110', '天府三街', '2017-06-06'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('小强', 18, '69776977', '中和镇', '2017-06-06'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('小迪', 22, '1456789', '天华苑', '2017-06-01'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('情歌', 24, '6454422', '成都', '2017-05-31'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('周三', 23, '1223154', '德阳', '2017-06-01'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('红牛', 32, '120', '黄山', '2017-05-31'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('大米', 16, '180', '新希望', '2017-06-04'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('小米', 22, '180', '贝立美', '2017-06-04'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('黑米', 36, '180', '新希望', '2017-06-04'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('红米', 24, '180', '一楼', '2017-06-04'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('大豆', 25, '180', '二流', '2017-06-04'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('绿豆', 26, '180', '三楼', '2017-06-04'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('灰豆', 19, '180', '四楼', '2017-06-04'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('欧阳修', 23, '122', '五棵松', '2017-05-28'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('韩明', 12, '120', '鸟巢', '2017-05-29'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('李修', 21, '120', '长安', '2017-06-14'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('韩梅梅', 12, '2132354354', '大坪', '2017-06-01'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('东北F4', 99, '121313121', '铁岭', '2017-06-01'); INSERT INTO test.student (stuName, stuAge, mobile, address, EntranceTime) VALUES ('赵四', 32, '44111221', '东北', '2017-06-07');

 

 

3      对项目目录结构进行完善

3.1   JDK环境确认

 

 

 

 

3.2   编译环境确认

7      实现spring以及与mybatis的整合的配置

在resource目录下新建spring-mybaits.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" 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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd "> <!-- 自动扫描 --> <context:component-scan base-package="com.deng.ssm.service" /> <!-- 引入实现JDBC配置文件 --> <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location" value="classpath:jdbc.properties" /> </bean> <!-- 2.数据库连接池 --> <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> <!-- 配置连接池属性 --> <!-- 此处 ${Driver} 中的 ${属性名} 是访问属性文件中的指定属性--> <property name="driverClass" value="${driver}" /> <property name="jdbcUrl" value="${url}" /> <property name="user" value="${username}" /> <property name="password" value="${password}" /> <!-- c3p0连接池的私有属性 --> <property name="maxPoolSize" value="${maxActive}" /> <property name="minPoolSize" value="${minActive}" /> <property name="initialPoolSize" value="${initialSize}"/> <!-- 关闭连接后不自动commit --> <property name="autoCommitOnClose" value="${autoCommitOnClose}" /> <!-- 获取连接超时时间 --> <property name="checkoutTimeout" value="${maxWait}" /> <!-- 当获取连接失败重试次数 --> <property name="acquireRetryAttempts" value="2" /> </bean> <!-- spring和MyBatis整合，通过spring来管理MyBatis的SqlSessionFactory会话工厂 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 指定数据库连接池引用 --> <property name="dataSource" ref="dataSource" /> <!-- 指定mybatis的配置文件路径，该配置文件下不需要再定义数据库连接信息和mapper信息了，但是可以 有一些关于mybatis的配置信息--> <property name="configLocation" value="classpath:mybatis.xml"/> <!-- 指定mybatis的mapper配置文件路径，*代表通配符所有的意思 value可以指定多个，由英文逗号分隔 --> <property name="mapperLocations" value="classpath:com/deng/ssm/mapper/*.xml"></property> </bean> <!-- 定义sqlSession对象，通过SqlSessionTemplate来产生，需要在构造方法中指定会话工厂 相当于原来mybatis中的sessionFactory.openSession();SqlSessionTemplate是线程安全的，所以采用单例模式 --> <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate" destroy-method="clearCache"> <!--注入会话工厂--> <constructor-arg index="0" ref="sqlSessionFactory"/> <!--定义采用何种形式操作数据库，需要注意若是BATCH的话增删改返回的将不是影响的行数 默认为SIMPLE--> <!--<constructor-arg index="1" value="BATCH"/>--> </bean> <!-- 定义mybaits的DAO接口所在的包名，spring会自动查找其下的接口，并为其自动创建bean，无需我们定义 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.deng.ssm.dao" /> <property name="sqlSessionTemplateBeanName" value="sqlSessionTemplate"/> </bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!-- (事务管理)使用注解的方式来管理实务 --> <!--<tx:annotation-driven transaction-manager="transactionManager"/>--> <!-- 定义事务的切面（通知） --> <tx:advice id="txAdvice" transaction-manager="transactionManager" > <tx:attributes > <!-- 定义方法的事务规则 --> <tx:method name="add*" propagation="REQUIRED" /> <tx:method name="insert*" propagation="REQUIRED"/> <tx:method name="update*" propagation="REQUIRED"/> <tx:method name="del*" propagation="REQUIRED"/> <tx:method name="modify*" propagation="REQUIRED"/> <tx:method name="*" propagation="NEVER" read-only="true"/> </tx:attributes> </tx:advice> <!--通过AOP启用事务--> <aop:config> <aop:pointcut id="pt" expression="execution(* com.deng.ssm.service.impl.*.*(..))"/> <aop:advisor advice-ref="txAdvice" pointcut-ref="pt" /> </aop:config> </beans>

11 通过一个显示所有学生的实例来验证框架是否搭建完成

11.1     创建学生bean

在com.deng.ssm.bean下建立类Student

package com.deng.ssm.bean; import java.util.Date; public class Student { private Integer id; private String stuName; private int stuAge; private String mobile; private String address; private Date entranceTime; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getStuName() { return stuName; } public void setStuName(String stuName) { this.stuName = stuName; } public int getStuAge() { return stuAge; } public void setStuAge(int stuAge) { this.stuAge = stuAge; } public String getMobile() { return mobile; } public void setMobile(String mobile) { this.mobile = mobile; } public String getAddress() { return address; } public void setAddress(String address) { this.address = address; } public Date getEntranceTime() { return entranceTime; } public void setEntranceTime(Date entranceTime) { this.entranceTime = entranceTime; } }

 

11.2     新建学生的数据操作接口IStudentDAO

11.3     建立学生的Mapper文件

在resource的com/deng/ssm/mapper目录下新建StudentMapper.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPEmapper PUBLIC"-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <!-- 注意命名空间为该maper文件对应的DAO的全路径 --> <mapper namespace="com.deng.ssm.dao.IStudentDAO" > <!--定义resultmap type的值为Student实体类名称，因为指定包的别名所以不用全路径 --> <resultMap id="student_map" type="Student"> <id property="id" column="id"/> <result property="stuName" column="stuName"/> <result property="stuAge" column="stuAge"/> <result property="mobile" column="mobile"/> <result property="address" column="address"/> <result property="entranceTime" column="entranceTime"/> </resultMap> <!--需要注意id的值等于接口中方法的名字--> <select id="searchAll" resultMap="student_map"> select id,stuName, stuAge, mobile, address, EntranceTime from student </select> </mapper>

 

11.4     建立学生的service接口

在包com.deng.ssm.service下建立StudentService接口
