spring 下事务控制失败- -

Question

applicationContext.xml配置如下：

[code="java"]<?xml version="1.0" encoding="UTF-8"?>

测试代码为：

[code="java"]package com.mycom.dwr;

import java.sql.PreparedStatement;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {
public void test(){
String [] conf = new String[1];

    conf[0]="applicationContext.xml";

    ApplicationContext appContext = new ClassPathXmlApplicationContext(conf); 
    TestDwr us = (TestDwr)appContext.getBean("testDwr");
    us.getval();

}

}[/code]

[code="java"]package com.mycom.dwr;

import java.sql.Connection;
import java.sql.PreparedStatement;

import javax.naming.InitialContext;
import javax.sql.DataSource;
import javax.annotation.Resource;
import org.springframework.stereotype.Component;
import org.springframework.beans.factory.annotation.*;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.simple.SimpleJdbcTemplate;

import org.springframework.transaction.annotation.Propagation;
import org.springframework.transaction.annotation.Transactional;
import com.mycom.dao.BaseDao;

//@Component("BaseDao")
@Transactional
public class TestDwr implements BaseDao {
@Resource(name="simpleJdbcTemplate")
private SimpleJdbcTemplate simpleJdbcTemplate;
@Resource(name="dataSource")
private DataSource ds ;

@Resource(name="dataSource")
public void setDataSource(DataSource ds){
    this.ds=ds;
}

@Transactional
public String getval(){
    try {           
        String sql1 = "insert into dept(deptno,dname,loc) values (13,'eagle11','bj11')";
        String sql2 = "inser into dept(deptno,dname,loc) values (15,'eagle2','bj22')";
        simpleJdbcTemplate.update(sql1);
        simpleJdbcTemplate.update(sql2);
    } catch (Exception e) {
     e.printStackTrace();
    }
    return ret;
}

}[/code]

BaseDao.java:

[code="java"]package com.mycom.dao;

import javax.sql.DataSource;

public interface BaseDao {

public String getval();

}[/code]

执行测试程序Test。发现事务没有被控制

[b]问题补充：[/b]
谢谢，我增加
tx:annotation-driven/后

测试时代码执行到
TestDwr us = (TestDwr)appContext.getBean("BaseDao");

就不继续了。点解
[b]问题补充：[/b]
我测试时 //@Component("BaseDao") 是没注释的。 - -

如果启动事务控制tx:annotation-driven/ 执行到getbean那就不执行了。如果没有这句，代码可以执行，但没事务控制 - -

Answer 1

TestDwr us = (TestDwr)appContext.getBean("BaseDao"); ？ getBean应该按照bean的id来获取，BaseDao不是一个父类吗？ 改成(TestDwr)appContext.getBean("testDwr");应该就OK乐
