org.beetl.sql.core中Query的使用

返回Query的org.beetl.sql.core中的方法

限定符和类型	方法和说明
<T> Query<T>	DataAPI.query(Class<T> clazz)
<T> Query<T>	SQLManager.query(Class<T> clazz)
<T> Query<T>	ConditionalSQLManager.query(Class<T> clazz)

org.beetl.sql.core.query中Query的使用

org.beetl.sql.core.query中Query的子类

限定符和类型	类和说明
class	LambdaQuery<T> 用于方便的构造简单的sql操作，复杂的sql操作建议直接使用sql语句 @{code LambdaQuery query = ... ; List list = query.andEq(User::getName,"lijz").select(); } LambdaQuery 相对于Query，够能方便支持重构，通过User::getName这种形式获取列名。
