1、需要加载的包如下
spring.jar
commons-logging-1.0.4.jar
ibatis-2.3.3.720.jar
commons-dbcp.jar
commons-pool.jar
mysql-connector-java-5.0.8-bin.jar
2、创建数据库
  author.sql
1 create table author(
2id int auto_increment primary key,
3name varchar(20),
4address varchar(20),
5telphone varchar(11))
3、一个简单的javabean:com.sailor.vo.Author.java
Author.java
1/** *//**
2 *
3 */
4package com.sailor.vo;
5
6/** *//**
7 * @author sailor
8 *
9 */
10public class Author implements java.io.Serializable {
11
12  /** *//**
13 *
14 */
15 private static final long serialVersionUID = -2722692654067301576L;
16 private int id;
17 private int age;
18 private String name;
19 private String address;
20 private String telephone;
21
22 public Author() {
23 }
24
25
26 public Author(int id, int age, String name, String address, String telephone) {
27 super();
28 this.id = id;
29 this.age = age;
30 this.name = name;
31 this.address = address;
32 this.telephone = telephone;
33 }
34
35
36 /** *//**
37 * @return the id
38 */
39 public int getId() {
40 return id;
41 }
42 /** *//**
43 * @param id the id to set
44 */
45 public void setId(int id) {
46 this.id = id;
47 }
48 /** *//**
49 * @return the age
50 */
51 public int getAge() {
52 return age;
53 }
54 /** *//**
55 * @param age the age to set
56 */
57 public void setAge(int age) {
58 this.age = age;
59 }
60 /** *//**
61 * @return the name
62 */
63 public String getName() {
64 return name;
65 }
66 /** *//**
67 * @param name the name to set
68 */
69 public void setName(String name) {
70 this.name = name;
71 }
72 /** *//**
73 * @return the address
74 */
75 public String getAddress() {
76 return address;
77 }
78 /** *//**
79 * @param address the address to set
80 */
81 public void setAddress(String address) {
82 this.address = address;
83 }
84 /** *//**
85 * @return the telephone
86 */
87 public String getTelephone() {
88 return telephone;
89 }
90 /** *//**
91 * @param telephone the telephone to set
92 */
93 public void setTelephone(String telephone) {
94 this.telephone = telephone;
95 }
96
97
98 /**//* (non-Javadoc)
99 * @see java.lang.Object#toString()
100 */
101 @Override
102 public String toString() {
103 return "ID: " + this.id + " name: " + this.getName() +
104 " age: " + this.age + " tel: " + this.telephone + " address: " + this.address;
105 }
106}
107
4、配置sqlMap
author.xml
1<?xml version="1.0" encoding="UTF-8" ?>
2<!DOCTYPE sqlMap
3 PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN"
4 "http://www.ibatis.com/dtd/sql-map-2.dtd">
5
6
7 <sqlMap namespace="Author">
8
9 <!-- 定义类的别名 -->
10 <typeAlias alias="Author" type="com.sailor.vo.Author" />
11
12 <cacheModel id="authorCache" type="LRU">
13 <flushInterval hours="24"/>
14 <flushOnExecute statement="insertAuthor"/>
15 <flushOnExecute statement="updateAuthor"/>
16 <flushOnExecute statement="deleteAuthor"/>
17 <property name="size" value="1000" />
18 </cacheModel>
19
20 <resultMap id="authorResult" class="Author">
21 <result property="id" column="auth_id" jdbcType="int" javaType="java.lang.Integer"/>
22 <result property="name" column="auth_name" jdbcType="VARCHAR" javaType="java.lang.String"/>

26 </resultMap>
27
28 <parameterMap id="insert-para" class="Author">
29 <parameter property="id"/>
30 <parameter property="name"/>
31 <parameter property="age"/>
32 <parameter property="telephone"/>
33 <parameter property="address"/>
34 </parameterMap>
35
36 <!-- 按ID返回该作者详细信息 -->
37 <select id="getAuthor" parameterClass="int" resultClass="Author">
38 SELECT auth_id as id,
39 auth_name as name,
40 auth_age as age,
41 auth_tel as telephone,
42 auth_address as address
43 FROM author WHERE auth_id = #id#
44 </select>
45
46 <!-- 列出所有的作者 -->
47
48 <statement id="getAllAuthor" resultMap="authorResult" cacheModel="authorCache">
49 <!-- <select id="getAllAuthor" resultClass="java.util.HashMap"> -->
50 SELECT * FROM author
51 </statement>
52
53
54 <!-- 新增作者 -->
55 <insert id="insertAuthor" parameterClass="Author">
56 INSERT INTO author (auth_id, auth_name,auth_age,auth_tel,auth_address) VALUES (#id#, #name#, #age#, #telephone#, #address#)
57 <selectKey resultClass="int" type="post" keyProperty="id" >
58 select LAST_INSERT_ID() as value
59 </selectKey>
60 </insert>
61
62 <!--
63 <statement id="insertAuthor" parameterMap="insert-para">
64 INSERT INTO author (auth_id, auth_name,auth_age,auth_tel,auth_address) VALUES (?, ?, ?, ?, ?)
65 <selectKey resultClass="int" type="post" keyProperty="id" >
66 select LAST_INSERT_ID() as value
67 </selectKey>
68 </statement>
69 -->
70
71
72 <!-- 更新作者信息 -->
73 <update id="updateAuthor" parameterClass="Author">
74 UPDATE author set auth_name=#name# WHERE auth_id = #id#
75 </update>
76
77 <!-- 按ID删除作者信息 -->
78 <delete id="deleteAuthor" parameterClass="int">
79 delete from author WHERE auth_id = #id#
80 </delete>
81
82 </sqlMap>
83
84
5、配置SqlMapConfig.xml
sqlMapConfig.xml
1<?xml version="1.0" encoding="UTF-8" ?>
2<!DOCTYPE sqlMapConfig
3 PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN"
4 "http://www.ibatis.com/dtd/sql-map-config-2.dtd">
5
6 <!-- Always ensure to use the correct XML header as above! -->
7
8 <sqlMapConfig>
9
10 <!-- These settings control SqlMapClient configuration details, primarily to do with transaction
11 management. They are all optional (more detail later in this document). -->
12
13 <settings
14 cacheModelsEnabled="true"
15 enhancementEnabled="true"
16 lazyLoadingEnabled="true"
17 maxRequests="32"
18 maxSessions="10"
19 maxTransactions="5"
20 useStatementNamespaces="false"
21 />
22
23
24 <!-- Identify all SQL Map XML files to be loaded by this SQL map. Notice the paths
25 are relative to the classpath. For now, we only have one… -->
26 <sqlMap resource="com/sailor/dao/author.xml" />
27
28 </sqlMapConfig>
29
6、编写dao 文件
IAuthor.java
1/** *//**
2 *
3 */
4package com.sailor.dao;
5
6import java.util.List;
7
8import com.sailor.vo.Author;
9
10/** *//**
11 * @author sailor
12 * Sep 5, 2008 4:23:39 PM
13 */
14public interface IAuthorDAO {
15
16 /** *//**
17 * 增加作者
18 * @param author
19 */
20 public void saveAuthor(Author author);
21
22 /** *//**
23 * 修改作者
24 * @param author
25 */
26 public void updateAuthor(Author author);
27
28 /** *//**
29 * 删除作者
30 * @param author
31 */
32 public void deleteAuthor(Author author);
33
34 /** *//**
35 * 获得List
36 * @return
37 */
38 public List<Author> getAllAuthor();
39
40 /** *//**
41 * 按ID查看
42 * @param id
43 * @return
44 */
45 public Author getAuthorById(int id);
46}
47
AuthorDAO.java
1/** *//**
2 *
3 */
4package com.sailor.dao;
5
6import java.util.List;
7
8import org.springframework.orm.ibatis.SqlMapClientTemplate;
9
10import com.sailor.vo.Author;
11
12/** *//**
13 * @author sailor
14 * Sep 5, 2008 4:24:57 PM
15 */
16public class AuthorDAO implements IAuthorDAO {
17
18 private SqlMapClientTemplate sqlMapClientTemplate;
19
20 public SqlMapClientTemplate getSqlMapClientTemplate() {
21 return sqlMapClientTemplate;
22 }
23
24 public void setSqlMapClientTemplate(SqlMapClientTemplate sqlMapClientTemplate) {
25 this.sqlMapClientTemplate = sqlMapClientTemplate;
26 }
27
28 /** *//**
29 * 删除一个作者
30 */
31 public void deleteAuthor(Author author) {
32
33 sqlMapClientTemplate.delete("deleteAuthor", author);
34 }
35
36
37 /** *//**
38 * 获取List列表
39 */
40 @SuppressWarnings("unchecked")
41 public List<com.sailor.vo.Author> getAllAuthor() {
42
43 return sqlMapClientTemplate.queryForList("getAllAuthor");
44 }
45
46
47 /** *//**
48 * 按ID查询详细信息
49 */
50 public com.sailor.vo.Author getAuthorById(int id) {
51
52 return (Author)sqlMapClientTemplate.queryForObject("getAuthor", new Integer(id));
53 }
54
55 /** *//**
56 * 保存作者详细信息
57 */
58 public void saveAuthor(Author author) {
59
60 sqlMapClientTemplate.insert("insertAuthor", author);
61 }
62
63 /** *//**
64 * 更新作者信息
65 */
66 public void updateAuthor(Author author) {
67
68 sqlMapClientTemplate.update("updateAuthor", author);
69 }
70}
71
7、配置applicationContext.xml
applicationContext.xml
1<?xml version="1.0" encoding="UTF-8"?>
2<beans
3 xmlns="http://www.springframework.org/schema/beans"
4 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
5 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd">
6
7 <!-- 配置数据源 -->
8 <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
9 <property name="driverClassName">
10 <value>com.mysql.jdbc.Driver</value>
11 </property>
12 <property name="username">
13 <value>root</value>
14 </property>
15 <property name="password">
16 <value>sa</value>
17 </property>
18 <property name="url">
19 <value>jdbc:mysql://localhost:3306/test</value>
20 </property>
21 </bean>
22
23
24 <!-- 配置Dao层 -->
25
26 <!--根据dataSource和configLocation创建一个SqlMapClient-->
27 <bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
28 <property name="configLocation">
29 <!-- 本Demo是个application,如果是个web Project，路径应为/WEB-INF/lib/classes/SqlMapConfig.xml -->
30 <value>SqlMapConfig.xml</value>
31 </property>
32 <property name="dataSource">
33 <ref bean="dataSource" />
34 </property>
35 </bean>
36
37 <!--根据sqlMapClien创建一个SqlMapClient模版类-->
38 <bean id="sqlMapClientTemplate"
39 class="org.springframework.orm.ibatis.SqlMapClientTemplate">
40 <property name="sqlMapClient">
41 <ref bean="sqlMapClient" />
42 </property>
43 </bean>
44
45 <!--将上面的模版类织入到我们的DAO对象中-->
46 <bean id="authorDAO" class="com.sailor.dao.AuthorDAO">
47 <property name="sqlMapClientTemplate">
48 <ref bean="sqlMapClientTemplate" />
49 </property>
50 </bean>
51
52
53</beans>
54
8、客户端测试
TestClient.java
1import java.util.List;
2
3import org.springframework.context.ApplicationContext;
4import org.springframework.context.support.ClassPathXmlApplicationContext;
5
6
7import com.sailor.dao.AuthorDAO;
8import com.sailor.vo.Author;
9
10/** *//**
11 *
12 */
13
14/** *//**
15 * @author sailor
16 * Sep 5, 2008 4:46:30 PM
17 */
18public class TestClient {
19
20 /** *//**
21 * @param args
22 */
23 public static void main(String[] args) {
24
25 System.out.println("读取配置文件");
26 ApplicationContext factory = new ClassPathXmlApplicationContext("applicationContext.xml");
27 AuthorDAO authorDao = (AuthorDAO)factory.getBean("authorDAO");
28 System.out.println("get List");
29 List<Author> list = authorDao.getAllAuthor();
30 System.out.println("print List");
31 for(Author author : list){
32 System.out.println(author);
33 }
34 }
35}
