Ibatis+Spring整合实例Demo+源码

Ibatis+Spring整合实例Demo+源码java工作 
阅读更多

    <span style="color: #ff0000;">1. 单独整合ibatis</span>

ibatis和hibernate一样, 总体上没有hibernate那么强大.但是ibatis简单易用.

区别:

hibernate中每个实体类配置的注解和xml对应于数据库,ORM关系看比较紧;查询更新以实体对象为基准;

ibatis中每个实体也配置xml和实体类(entity和数据库对应的字段);配置要用的SQL语句;

?

<span style="color: #ff0000;">A. 见证实体对象User.java</span>

package cn.edu.zju.jjh.entity;

import java.io.Serializable;
/****
 * 
 * @author greatwqs
 * @date 2011-12-02
 */
public class User implements Serializable {

	private static final long serialVersionUID = 1L;
	private String id;
	private String name;
	private String password;
	private String description;

	// getter and setter
}

?

<span style="color: #ff0000;">B. 对应实体的ibatis的xml配置信息.Users.xml</span>

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE sqlMap      
    PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN"      
    "http://ibatis.apache.org/dtd/sql-map-2.dtd">

<sqlMap namespace="User">

	<!-- Use type aliases to avoid typing the full classname every time. -->
	<typeAlias alias="User" type="cn.edu.zju.jjh.entity.User" />

	<!-- Result maps describe the mapping between the columns returned
		from a query, and the class properties.  A result map isn't
		necessary if the columns (or aliases) match to the properties 
		exactly. -->
	<resultMap id="UserResult" class="User">
		<result property="id" column="id" />
		<result property="name" column="name" />
		<result property="password" column="password" />
		<result property="description" column="description" />
	</resultMap>

	<!-- Select with no parameters using the result map for Account class. -->
	<select id="selectAllUsers" resultMap="UserResult">
		select * from Users
	</select>

	<!-- A simpler select example without the result map.  Note the 
		aliases to match the properties of the target result class. -->
	<select id="selectUserById" parameterClass="String"
		resultClass="User">
		select id as id, name as name, password as password, description
		as description from Users where id = #id#
	</select>

	<!-- Insert example, using the Account parameter class -->
	<insert id="insertUser" parameterClass="User">
		insert into Users (id,name, password,description) values ( #id#,
		#name#, #password#, #description#)
	</insert>

	<!-- Update example, using the Account parameter class -->
	<update id="updateAccount" parameterClass="User">
		update Users set name = #name#, password = #password#,
		description = #description# where id = #id#
	</update>

	<!-- Delete example, using an integer as the parameter class -->
	<delete id="deleteUserById" parameterClass="String">
		delete from Users where id = #id#
	</delete>

</sqlMap>

?

?

主要是数据库字段和实体字段的对应和常用SQL的配置.

?

<span style="color: #ff0000;">C. ibatis总的配置文件 SqlMapConfig.xml</span>

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE sqlMapConfig      
    PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"      
    "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">

<sqlMapConfig>

  <!-- Configure a built-in transaction manager.  If you're using an 
       app server, you probably want to use its transaction manager 
       and a managed datasource -->
  <transactionManager type="JDBC" commitRequired="false">
    <dataSource type="SIMPLE">
      <property name="JDBC.Driver" value="com.mysql.jdbc.Driver"/>
      <property name="JDBC.ConnectionURL" value="jdbc:mysql://localhost:3306/ibatistest"/>
      <property name="JDBC.Username" value="root"/>
      <property name="JDBC.Password" value="greatwqs"/>
    </dataSource>
  </transactionManager>

  <!-- List the SQL Map XML files. They can be loaded from the 
       classpath, as they are here (com.domain.data...) -->
  <sqlMap resource="cn/edu/zju/jjh/entity/Users.xml"/>
  <!-- List more here...
  <sqlMap resource="com/mydomain/data/Order.xml"/>
  <sqlMap resource="com/mydomain/data/Documents.xml"/>
  -->

</sqlMapConfig>

<span style="color: #ff0000;">D: 测试IbatisTest.java</span>

package cn.edu.zju.jjh;

import java.io.IOException;
import java.io.Reader;
import java.sql.SQLException;

import cn.edu.zju.jjh.entity.User;

import com.ibatis.common.resources.Resources;
import com.ibatis.sqlmap.client.SqlMapClient;
import com.ibatis.sqlmap.client.SqlMapClientBuilder;

public class IbatisTest {
	/***
	 * 使用纯Ibatis进行测试!
	 */
	public static void main(String[] args) {
		String resource = "sqlMapConfig_ibatis.xml";
		Reader reader;
		SqlMapClient sqlMap = null;
		try {
			reader = Resources.getResourceAsReader(resource);
			sqlMap = SqlMapClientBuilder.buildSqlMapClient(reader);
			sqlMap.startTransaction();
			User user = new User();
			user.setId("1099");
			user.setName("EagleWang");
			user.setPassword("EaglePassword");
			user.setDescription("Email: greatwqs@163.com");
			sqlMap.insert("insertUser", user);
			sqlMap.commitTransaction();
			sqlMap.endTransaction();
		} catch (IOException e) {
			e.printStackTrace();
		} catch (SQLException e) {
			e.printStackTrace();
		}
	}
}

执行测试成功:

DEBUG-Created connection 1073282.
DEBUG-{conn-100000} Connection

<span style="color: #ff0000;">?</span>

<span style="color: #ff0000;">2. Spring整合Ibatis</span>

通过上面的配置测试成功,证明ibatis能独立测试成功!

A. Spring配置如下:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd">

<beans>
	<!-- 配置数据源,这里配置在Spring中,就不需要在ibatis中配置数据源了 -->
	<bean id="dataSource"
		class="org.apache.commons.dbcp.BasicDataSource"
		destroy-method="close">
		<property name="driverClassName">
			<value>com.mysql.jdbc.Driver</value>
		</property>
		<property name="url">
			<value>jdbc:mysql://localhost:3306/ibatistest</value>
		</property>
		<property name="username">
			<value>root</value>
		</property>
		<property name="password">
			<value>greatwqs</value>
		</property>
	</bean>
	
	<!-- spring对ibatis配置文件读取的实现,指定ibatis配置文件的目录,配置文件只需放置有哪些实体的xml所在位置 -->
	<bean id="sqlMapClient"
		class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
		<property name="configLocation">
			<value>SqlMapConfig_spring.xml</value>
		</property>
	</bean>
	
	<!-- Spring配置事务,ref = 数据源 -->
	<bean id="transactionManager"
		class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource">
			<ref local="dataSource" />
		</property>
	</bean>
	
	<!-- 与hibernate相似,如果需要建立DAO层,传入链接数据源+ibatis特有的sqlMapClient,而在DAO中要继承类SqlMapClientDaoSupport,hibernate中是HibernateDaoSupport -->
	<bean id="userDao" class="cn.edu.zju.jjh.dao.UserDaoImpl">
		<property name="dataSource">
			<ref local="dataSource" />
		</property>
		<property name="sqlMapClient">
			<ref local="sqlMapClient" />
		</property>
	</bean>
	
	<!-- userDaoProxy为一个userDao的形式,中间加入事务的支持,在action中UserDaoInterface userDao = (UserDaoInterface) springContex.getBean("userDaoProxy"); -->
	<bean id="userDaoProxy"
		class="org.springframework.transaction.interceptor.TransactionProxyFactoryBean">
		<property name="transactionManager">
			<ref bean="transactionManager" />
		</property>
		<property name="target">
			<ref local="userDao" />
		</property>
		<property name="transactionAttributes">
			<props>
				<prop key="insert*">PROPAGATION_REQUIRED</prop>
				<prop key="get*">PROPAGATION_REQUIRED,readOnly</prop>
			</props>
		</property>
	</bean>
</beans>

?

B. SqlMapConfig_spring.xml只需配置:(与上面1.C中的配置文件做比较)

<?xml version="1.0" encoding="UTF-8" ?>

<!DOCTYPE sqlMapConfig      
    PUBLIC "-//ibatis.apache.org//DTD SQL Map Config 2.0//EN"      
    "http://ibatis.apache.org/dtd/sql-map-config-2.dtd">

<sqlMapConfig>

	<!-- List the SQL Map XML files. They can be loaded from the classpath, as they are here (com.domain.data...) -->
	<sqlMap resource="cn/edu/zju/jjh/entity/Users.xml" />
	
	<!-- 
	    List more here...
	    <sqlMap resource="com/mydomain/data/Order.xml"/>
		<sqlMap resource="com/mydomain/data/Documents.xml"/>
	-->
</sqlMapConfig>

?C. Spring+ibatis集成测试代码

package cn.edu.zju.jjh;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import cn.edu.zju.jjh.dao.UserDaoInterface;
import cn.edu.zju.jjh.entity.User;

public class SpringTest {

	public static void main(String arg[]){
		ClassPathXmlApplicationContext ac = new ClassPathXmlApplicationContext("applicationContext.xml");
		UserDaoInterface userDao = (UserDaoInterface) ac.getBean("userDaoProxy");
		try {
			User user = new User();
			user.setId("20001");
			user.setName("greatwqs");
			user.setPassword("GreatPassword");
			user.setDescription("Email: greatwqs@126.com");
			userDao.insertUser(user);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}
