jdbc 용 스프링 트랜잭션 관리자가 작동하지 않는 이유는 무엇입니까?

Question

내가 JDBC의 트랜잭션 매니저를 config (설정),하지만 내가 할 때 :

dao.insert(something); 
throw new UnsupportedOperationException(); 

트랜잭션 그것은 간단한 예제

<aop:aspectj-autoproxy /> 

<!-- define JDBC datasource by DBCP --> 
    <bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close"> 
     <property name="driverClassName" value="com.mysql.jdbc.Driver" /> 
     <property name="url" value="jdbc:mysql://localhost:3306/ts" /> 
     <property name="username" value="root" /> 
     <property name="password" value="1234" /> 
    </bean> 

    <!-- DataSourceTransactionManager for jdbc --> 
    <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> 
     <property name="dataSource" ref="dataSource"/> 
    </bean> 

    <bean id="fooDao" class="com.oolong.dao.FooDao"> 
     <property name="dstm" ref="txManager"></property> 
    </bean> 

    <bean id="fooService" class="com.oolong.service.DefaultFooService"> 
     <property name="fooDao" ref="fooDao"></property> 
    </bean> 

    <tx:advice id="txAdvice" transaction-manager="txManager"> 
     <tx:attributes> 
      <tx:method name="get*" read-only="true" propagation="REQUIRED"/> 
      <tx:method name="*" read-only="false" propagation="REQUIRED" 
       rollback-for="java.lang.RuntimeException"/> 
     </tx:attributes> 
    </tx:advice> 

    <aop:config> 
     <aop:pointcut id="fooServiceOperation" expression="execution(* com.oolong.service.FooService.*(..))"/> 
     <aop:advisor advice-ref="txAdvice" pointcut-ref="fooServiceOperation"/> 
    </aop:config> 

을 롤백하지 않습니다하는 DefaultFooService는 FooService 인터페이스를 구현합니다. 서비스에는 DAO가 있고, FooDao에는 메소드가 테이블에 레코드를 삽입합니다.

코드를 실행할 때. 거래가 생성되지 않았습니다! 물론 롤백 할 수는 없습니다.

FooService 인터페이스

package com.oolong.service; 

import com.oolong.model.Foo; 

public interface FooService { 

    Foo getFoo(String fooName); 

    Foo getFoo(String fooName, String barName); 

    void insertFoo(Foo foo); 

    void updateFoo(Foo foo); 
} 

DefaultFooService.java

package com.oolong.service; 

import com.oolong.dao.FooDao; 
import com.oolong.model.Foo; 

public class DefaultFooService implements FooService { 

    private FooDao fooDao; 

    public void setFooDao(FooDao fooDao) { 
     this.fooDao = fooDao; 
    } 

    public Foo getFoo(String fooName) { 

     throw new UnsupportedOperationException(); 
    } 

    public Foo getFoo(String fooName, String barName) { 
     throw new UnsupportedOperationException(); 
    } 

    public void insertFoo(Foo foo) { 
     fooDao.insert(); 
     throw new UnsupportedOperationException(); 
    } 

    public void updateFoo(Foo foo) { 
     throw new UnsupportedOperationException(); 
    } 
} 

FooDao.java

package com.oolong.dao; 

import java.sql.Connection; 
import java.sql.SQLException; 
import java.sql.Statement; 

import javax.sql.DataSource; 

import org.springframework.jdbc.datasource.DataSourceTransactionManager; 

public class FooDao { 

    private DataSourceTransactionManager dstm; 

    public void setDstm(DataSourceTransactionManager dstm) { 
     this.dstm = dstm; 
    } 

    public void insert() { 
     try { 
      DataSource ds = dstm.getDataSource(); 
      Connection conn = ds.getConnection(); 

      String sql = "insert into item (wid, answer, isCorrect, choiceWid) " 
        + "values ('1', '1', 1, '1')"; 

      Statement st = conn.createStatement(); 
      st.executeUpdate(sql); 

     } catch (SQLException e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
     } 
    } 
} 

AppContainer.java

public class AppContainer { 

    public static void main(final String[] args) throws Exception { 
     ApplicationContext ctx = new ClassPathXmlApplicationContext("/beans.xml", AppContainer.class); 
     FooService fooService = (FooService) ctx.getBean("fooService"); 
     fooService.insertFoo(new Foo()); 
    } 
}

JdbcTemplate을 사용해야합니다.
