  • ibatis与spring继承

     作为开源的Orm对象映射框架,ibatis是一个线程安全,学习容易,但是开发相对于hibernate来说的话,就要繁锁些,没有很好的工具支持ibatis所有的配置几乎是通过手写,这样增加了开发者的难度、、好啦,言归正转。下面编写实现。

        一、引入spring,ibatis jar包.

        二、编写log4j.properties日志文件

              log4j.rootLogger=DEBUG,stdout

              log4j.appender.stdout=org.apache.log4j.ConsoleAppender       log4j.appender.stdout.layout=org.apache.log4j.PatternLayout       log4j.appender.stdout.layout.ConversionPattern=%c{1}% - %m%n

              log4j.logger.java.sql.PreparedStatement=DEBUG

        三、建立Student.java类映象属性

        package org.terry.ibatis.pojo;

        public class Student {  private Long id;

         private String name;

         private String subject;

         private Long score;

         public Long getId() {   return id;  }

         public void setId(Long id) {   this.id = id;  }

         public String getName() {   return name;  }

         public void setName(String name) {   this.name = name;  }

         public Long getScore() {   return score;  }

         public void setScore(Long score) {   this.score = score;  }

         public String getSubject() {   return subject;  }

         public void setSubject(String subject) {   this.subject = subject;  } }

        四、编写 student.xml 映象文件

        <?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="student">
      <typeAlias alias="student" type="org.terry.ibatis.pojo.Student"/>
      <resultMap class="student" id="studentResult">
       <result property="id" column="id" jdbcType="number" javaType="java.lang.Long"/>
       <result property="name" column="name"/>
       <result property="subject" column="subject"/>
       <result property="score" column="score"/>  </resultMap>
        <select id="selectAll" resultMap="studentResult">
       select * from student  </select>
        <select id="findbyId" parameterClass="java.lang.Long" resultClass="student">
       select * from student where id=#id#  </select>  <insert id="insert" parameterClass="student">
       insert into student(id,name,subject,score) values(#id#,#name#,#subject#,#score#)
      </insert>
      <update id="update" parameterClass="student">
       update student set name=#name#,subject=#subject#,score=#score# where id=#id# 
    </update>
      <delete id="delete" parameterClass="java.lang.Long">
       delete from student where id=#id#
      </delete>
    </sqlMap>

      

    五、编写 SqlMapConfig.xml文件

        <?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>
      <sqlMap resource="org/terry/ibatis/pojo/student.xml"/> </sqlMapConfig>

        六、编写 StudentDao.java(实现类)

        package org.terry.ibatis.dao;

        import java.io.IOException; import java.sql.SQLException; import java.util.List;

        import org.springframework.beans.factory.xml.XmlBeanFactory; import org.springframework.core.io.ClassPathResource; import org.springframework.core.io.Resource; import org.springframework.orm.ibatis.SqlMapClientCallback; import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport; import org.terry.ibatis.pojo.Student;

        import com.ibatis.sqlmap.client.SqlMapExecutor;

        public class StudentDao extends SqlMapClientDaoSupport implements Idao{

         public void delete(Long id) {
       this.getSqlMapClientTemplate().delete("delete", id);  }

         public Object findbyId(Long id) {
       return this.getSqlMapClientTemplate().queryForObject("findbyId", id);  }

         public List getAll() {
       return (List)this.getSqlMapClientTemplate().execute(new SqlMapClientCallback(){

           public Object doInSqlMapClient(SqlMapExecutor sqlMapper) throws SQLException {     return sqlMapper.queryForList("selectAll");
        }
           });
      }

         public void save(Object o) {
       this.getSqlMapClientTemplate().insert("insert", o);  }

         public void update(Object o) {
       this.getSqlMapClientTemplate().update("update", o);
      }
        public static void main(String[] args) throws IOException {
        Resource re=new ClassPathResource("Ibatis-Context.xml");
        XmlBeanFactory xml=new XmlBeanFactory(re);
        StudentDao student=(StudentDao)xml.getBean("studentDao");
        Student stu=new Student();
        stu.setId(Long.valueOf(16));
        stu.setName("terry");
        stu.setScore(Long.valueOf(99));
        stu.setSubject("数学");
        student.delete(Long.valueOf(16));
      }
    }

        七、配置 ApplicationContext.xml文件

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

     <beans>
      <bean id="dataSource"
       class="org.apache.commons.dbcp.BasicDataSource">
       <property name="driverClassName">
        <value>oracle.jdbc.driver.OracleDriver</value>
       </property>   <property name="url">
        <value>jdbc:oracle:thin:@localhost:1521:orcl</value>
       </property>
       <property name="username">
        <value>terry</value>
       </property>
       <property name="password">
        <value>terry</value>
       </property>
      </bean>
        <bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">
       <property name="configLocation" value="SqlMapConfig.xml"/>
       <property name="dataSource" ref="dataSource"></property>
      </bean>
        <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
       <property name="dataSource" ref="dataSource"></property>
      </bean>
       <!-- 配置事务拦截器 -->
        <bean id="transactionIterceptor" class="org.springframework.transaction.interceptor.TransactionInterceptor">
         <!-- 事务拦截器需要注入一个事务管理器 -->
         <property name="transactionManager" ref="transactionManager"></property>
         <property name="transactionAttributes">
          <props>
           <prop key="insert*">PROPAGATION_REQUIRED</prop>
           <prop key="find*,get*">PROPAGATION_REQUIRED,readOnly</prop>
           <prop key="*">PROPAGATION_REQUIRED</prop>
          </props>
         </property>
        </bean>
           <bean class="org.springframework.aop.framework.autoproxy.BeanNameAutoProxyCreator">
         <property name="beanNames">
          <list>
           <value>*Dao</value>
          </list>
         </property>
         <property name="interceptorNames">
          <list>
           <value>transactionIterceptor</value>
          </list>
         </property>
        </bean>
      <bean id="studentDao" class="org.terry.ibatis.dao.StudentDao">
       <property name="sqlMapClient" ref="sqlMapClient"></property>
      </bean>
    </beans>
