我有这个数据库配置：

    @Bean(destroyMethod = "close")
    public javax.sql.DataSource dataSource() {
        DataSource ds = new DataSource();
        ds.setDriverClassName("com.mysql.jdbc.Driver");
        ds.setUrl("jdbc:mysql://localhost/v2");
        ds.setUsername("java");
        ds.setPassword("mypass");
        ds.setInitialSize(5);
        ds.setMaxActive(10);
        ds.setMaxIdle(5);
        ds.setMinIdle(2);
        ds.setRemoveAbandoned(true);
        ds.setLogAbandoned(true);
        return ds;
    }

    @Bean
    public DataSourceTransactionManager txManager()
    {
        DataSourceTransactionManager tx= new DataSourceTransactionManager(dataSource());
        return tx;
    }
