springMVC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

5.测试

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);
 }

}
