Spring+iBatis整合(业务层聚合SqlMapClientTemplate)

PS：

用的是业务层聚合SqlMapClientTemplate的方法，

步骤八中持有一个spring<bean>出来的SqlMapClientTemplate对象

Spring和Ibatis框架整合的思路与spring和hibernate框架的整合思路基本一致。

步骤一：新建立一个项目。
步骤二：为该项目添加spring的应用环境。
步骤三：导入Ibatis的必须JAR包以及数据库JAR包。
步骤四：新建实体Bean。如下：

package cn.test.entity;import java.io.Serializable;/*** @author Administrator**学生实体Bean**/public class Student implements Serializable {/**/private static final long serialVersionUID = 1L;private Integer id;private String studentname;private Integer studentage;private String studentaddress;public Integer getId() {return id;}public void setId(Integer id) {this.id = id;}public String getStudentname() {return studentname;}public void setStudentname(String studentname) {this.studentname = studentname;}public Integer getStudentage() {return studentage;}public void setStudentage(Integer studentage) {this.studentage = studentage;}public String getStudentaddress() {return studentaddress;}public void setStudentaddress(String studentaddress) {this.studentaddress = studentaddress;}}

步骤五：新建相应的Bean的配置文件。如下：Student.xml

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE sqlMapPUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN""http://ibatis.apache.org/dtd/sql-map-2.dtd"><sqlMap><!-- 查询操作 --><select id="getAllStudent" resultClass="cn.test.entity.Student">select * from student where 1=1</select><!-- 通过编号获取信息 --><select id="getStudentById" resultClass="cn.test.entity.Student" parameterClass="Integer">select * from student where id=#ids#</select></sqlMap>

步骤六：新建Ibatis的应用配置文件。sql-map-config.xml

<?xml version="1.0″ encoding="UTF-8″?><!DOCTYPE sqlMapConfigPUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN""http://ibatis.apache.org/dtd/sql-map-config-2.dtd"><sqlMapConfig><!--通知spring到哪里去寻找配置文件--><sqlMap resource="cn/test/configfile/Student.xml"/></sqlMapConfig>

步骤七：修改spring的applicationContext.xml文件。添加如下代码：

<!-- 配置数据源 --><bean id="dataSource"><property name="driverClassName"><value>com.mysql.jdbc.Driver</value></property><property name="url"><value>jdbc:mysql://localhost:3306/test</value></property><property name="username"><value>root</value></property><property name="password"><value>root</value></property></bean><!-- spring的ibatis 配制 --><bean id="sqlMapClient"><property name="dataSource"><ref bean="dataSource"/></property><property name="configLocation"><value>cn/test/configfile/sql-map-config.xml</value></property></bean><!-- 配置模板 --><bean id="sqlMapClientTemplate"><property name="sqlMapClient"><ref bean="sqlMapClient"/></property></bean>

步骤八：书写数据持久层次以及业务层代码。数据持久层代码如下：

public class StudentDAOImple implements IStudentDAO{private SqlMapClientTemplate sqlMapClientTemplate;public void setSqlMapClientTemplate(SqlMapClientTemplate sqlMapClientTemplate) {this.sqlMapClientTemplate = sqlMapClientTemplate;}public List<Student> getAllStudent() {List<Student> list = sqlMapClientTemplate.queryForList(“getAllStudent”);return list;}}

以及修改修改spring的applicationContext.xml文件

<!-- DAO --><bean id="studentDAO"><property name="sqlMapClientTemplate"><ref bean="sqlMapClientTemplate"/></property></bean>

步骤九：建立测试类及测试方法

public class Test {/*** @param args*/public static void main(String[] args) {ApplicationContext factory = new ClassPathXmlApplicationContext("applicationContext.xml");IStudentDAO dao = (IStudentDAO) factory.getBean("studentDAO");List<Student> list = dao.getAllStudent();for (int i = 0; i < list.size(); i++) {Student stu = list.get(i);System.out.println(stu.getId()+":"+stu.getStudentname()+":"+stu.getStudentage()+":"+stu.getStudentaddress());}}}

通过以上的配置，相信对SSI的配置也应该易如反掌了吧！
