Spring 操作数据库

试了一下spring的JdbcTemplate觉得很好用。首先增加一个连接到mysql数据库的dataSource

<bean id="dataSource2" class="org.springframework.jdbc.datasource.DriverManagerDataSource" destroy-method="close">
        <property name="driverClassName"><value>org.hibernate.dialect.MySQLDialect</value></property>
        <property name="url">
            <value>jdbc:mysql://192.168.0.240:3306/wordpressωuseUnicode=true&amp;characterEncoding=utf8</value>
            </property>
        <property name="username"><value>root</value></property>
        <property name="password"><value></value></property>
    </bean>

 public void testCopyData() throws Exception{
        DataSource ds = (DataSource)applicationContext.getBean("dataSource2");
        
        CategoryManager cateManager = (CategoryManager) applicationContext.getBean("categoryManager");
        
        JdbcTemplate jt = new JdbcTemplate(ds);
        System.out.println("Total posts:"+jt.queryForInt("select count(*) from wp_posts"));
        assertNotNull(ds);
        
        List cates = jt.queryForList("select * from wp_categories");
        int i= 0;
        for(Iterator ite = cates.iterator(); ite.hasNext();){
            i++;
            Map result = (Map) ite.next();
            Category cate = new Category();
            cate.setName((String)result.get("cat_name"));
            cate.setOrder(i);
            if(i==1)
                cate.setDefaultCategory(true);
            cateManager.saveCategory(cate);
            System.out.println("cat_name:"+result.get("cat_name")+"\n");
        }
    }
