本文介绍如何通过bboss 持久层框架相关查询api直接返回基础数据类型和基础数据类型List集合功能,基础数据类型包括以下几种:
{String.class,
		int.class ,Integer.class,
		long.class,Long.class,
		java.sql.Timestamp.class,java.sql.Date.class,java.util.Date.class,
		boolean.class ,Boolean.class,
		BigFile.class,//bboss的大文件对象
		float.class ,Float.class,
		short.class ,Short.class,
		double.class,Double.class,
		char.class ,Character.class,
		
		byte.class ,Byte.class,
		BigDecimal.class};


下面就是具体的使用方法,以SQLExecutor组件为例来说明(ConfigSQLExecutor类似,这里不做过多说明):

@Test
	public void dynamicqueryBean() throws SQLException
	{
		 ListBean bean = new ListBean();
		    bean.setFieldName("阿斯顿飞");
		 //<property name="refresh_interval" value="10000"/>
		 List<ListBean> result = SQLExecutor.queryListBean(ListBean.class, "select *  from LISTBEAN", bean);
		 System.out.println(result.size());
		  bean.setFieldName("");
		 result = (List<ListBean>) SQLExecutor.queryListBean(ListBean.class,"select *  from LISTBEAN", bean);
		 System.out.println(result.size());
		 
		 bean.setFieldName(null);
		 result = (List<ListBean>) SQLExecutor.queryListBean(ListBean.class,"select *  from LISTBEAN", bean);
		 
		 
		 System.out.println(result.size());
		 
		 List<String> result_string =  SQLExecutor.queryListBean(String.class,"select *  from LISTBEAN", bean);
		 
		 
		 System.out.println(result_string.size());
		 
		 List<Integer> result_int =  SQLExecutor.queryListBean(Integer.class,"select *  from LISTBEAN", bean);
		 
		 
		 System.out.println(result_int.size());
		 
	}
	
	@Test
	public void dynamicquery() throws SQLException
	{
		 
		List<ListBean> result =  SQLExecutor.queryList(ListBean.class,"select id  from LISTBEAN");
		 
		 
		 System.out.println(result.size());
		 
		 List<String> result_string =  SQLExecutor.queryList(String.class,"select id  from LISTBEAN");
		 
		 
		 System.out.println(result_string.size());
		 
		 List<Integer> result_int =  SQLExecutor.queryList(Integer.class,"select id  from LISTBEAN");
		 
		 
		 System.out.println(result_int.size());
		 
	}
	
	@Test
	public void dynamicqueryObject() throws SQLException
	{
		 
		ListBean result =  SQLExecutor.queryObject(ListBean.class,"select id  from LISTBEAN");
		 
		 
		 System.out.println(result.getId());
		 
		 String result_string =  SQLExecutor.queryObject(String.class,"select id  from LISTBEAN");
		 
		 
		 System.out.println(result_string);
		 
		 int result_int =  SQLExecutor.queryObject(int.class,"select id  from LISTBEAN");
		 
		 
		 System.out.println(result_int);
		 
	}
