[置顶] Spring3MVC实例

一、项目准备

   jar包：

     mybatis-spring-1.0.1.jar

     mybatis-3.0.5.jars

     spring3.1下的必须包

     数据库驱动

     其他一些零零碎碎的jar包（这些大家都懂的吧）

 

   数据表

   CREATE TABLE `notice` (
  `Author` varchar(255) default NULL,
  `Content` varchar(255) default NULL,
  `Title` varchar(255) default NULL,
  `AddTime` datetime default NULL,
  `NoticeId` int(11) NOT NULL auto_increment,
  PRIMARY KEY  (`NoticeId`)
  ) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;

 

二、各配置文件

  1. mybatis-config.xml

  <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//ibatis.apache.org//DTD Config 3.0//EN" "http://ibatis.apache.org/dtd/ibatis-3-config.dtd"> <configuration> <typeAliases> <typeAlias type="com.huaxin.bean.Notice" alias="notice" /> </typeAliases> <mappers> <mapper resource="com/huaxin/bean/notice-mapper.xml" /> </mappers> </configuration>

 

   2.Notice.java

public class Notice implements java.io.Serializable { private Integer noticeId; private String author; private Timestamp addTime; private String content; private String title; public Notice() { } public String getTitle() { return title; } public void setTitle(String title) { this.title = title; } public Integer getNoticeId() { return this.noticeId; } public void setNoticeId(Integer noticeId) { this.noticeId = noticeId; } public String getAuthor() { return this.author; } public void setAuthor(String author) { this.author = author; } public Timestamp getAddTime() { return this.addTime; } public void setAddTime(Timestamp addTime) { this.addTime = addTime; } public String getContent() { return this.content; } public void setContent(String content) { this.content = content; } }

  3.notice-mapper.xml

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//ibatis.apache.org//DTD Mapper 3.0//EN" "http://ibatis.apache.org/dtd/ibatis-3-mapper.dtd"> <mapper namespace="com.huaxin.dao.NoticeDao"> <resultMap type="notice" id="noticeResult"> <result column="NoticeId" property="noticeId" /> <result column="Title" property="title" /> <result column="AddTime" property="addTime" /> </resultMap> <select id="get" parameterType="int" resultType="notice" resultMap="noticeResult"> SELECT * FROM notice WHERE NoticeId = #{noticeId} </select> <insert id="save" parameterType="notice"> INSERT INTO notice (NoticeId, Title, AddTime) values (#{noticeId}, #{title}, #{addTime}) </insert> <delete id="delete" parameterType="int"> DELETE FROM notice WHERE NoticeId = #{noticeId} </delete> </mapper>

4.Spring配置文件

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd"> <beans> <bean id="placeholderConfig" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="location"> <value>classpath:init.properties</value> </property> </bean> <bean id="dataSource" class="com.jolbox.bonecp.BoneCPDataSource" destroy-method="close" dependency-check="none"> <property name="driverClass"> <value>${datasource.driverClassName}</value> </property> <property name="jdbcUrl"> <value>${datasource.url}</value> </property> <property name="username"> <value>${datasource.username}</value> </property> <property name="password"> <value>${datasource.password}</value> </property> <property name="idleConnectionTestPeriod"> <value>${boneCP.idleConnectionTestPeriod}</value> </property> <property name="idleMaxAge"> <value>${boneCP.idleMaxAge}</value> </property> <property name="maxConnectionsPerPartition"> <value>${boneCP.maxConnectionsPerPartition}</value> </property> <property name="minConnectionsPerPartition"> <value>${boneCP.minConnectionsPerPartition}</value> </property> <property name="partitionCount"> <value>${boneCP.partitionCount}</value> </property> <property name="acquireIncrement"> <value>${boneCP.acquireIncrement}</value> </property> <property name="statementsCacheSize"> <value>${boneCP.statementsCacheSize}</value> </property> <property name="statementsCachedPerConnection"> <value>${boneCP.statementsCachedPerConnection}</value> </property> <property name="releaseHelperThreads"> <value>${boneCP.releaseHelperThreads}</value> </property> </bean> <bean id="htm" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- datasource 配置jdbcTemplate --> <property name="dataSource"> <ref local="dataSource" /> </property> </bean> <bean id="txProxyTemplate" abstract="true" class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean"> <property name="transactionManager"> <ref bean="htm" /> </property> <property name="transactionAttributes"> <props> <prop key="create*"> PROPAGATION_REQUIRED,-com.ebay.exception.ApplyException </prop> <prop key="save*"> PROPAGATION_REQUIRED,-com.ebay.exception.ApplyException </prop> <prop key="remove*"> PROPAGATION_REQUIRED,-com.ebay.exception.ApplyException </prop> <prop key="update*"> PROPAGATION_REQUIRED,-com.ebay.exception.ApplyException </prop> <prop key="delete*"> PROPAGATION_REQUIRED,-com.ebay.exception.ApplyException </prop> <prop key="batch*"> PROPAGATION_REQUIRED,-com.ebay.exception.ApplyException </prop> <prop key="*">PROPAGATION_REQUIRED,readOnly</prop> </props> </property> </bean> <!-- ibatis配置 --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- <property name="mapperLocations" value="classpath:sample/config/mappers/**/*.xml" --> <property name="configLocation" value="classpath:mybatis-config.xml" /> <property name="dataSource" ref="dataSource" /> </bean> <!-- <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate"> <constructor-arg index="0" ref="sqlSessionFactory" /> </bean> --> <bean abstract="true" lazy-init="true" id="ibatis"> <property name="sqlSessionFactory" ref="sqlSessionFactory" /> </bean> <!-- ==================== End =================== --> <bean id="noticeService" parent="txProxyTemplate"> <property name="target"> <bean class="com.huaxin.service.NoticeServiceImpl"> <property name="noticeDao" ref="noticeDao" /> </bean> </property> </bean> <bean id="noticeDao" parent="ibatis" class="com.huaxin.dao.NoticeDaoImpl"/> </beans>

5.测试方法

public class NoticeDaoImpl extends SqlSessionDaoSupport implements NoticeDao { //SqlSessionDaoSupport里面有SqlSessionFactory属性 public Notice get(Integer id) { return (Notice) this.getSqlSession().selectOne("com.huaxin.dao.NoticeDao.get", id); } }
