Description: 原则上这不能说是一个持久层框架,它提供了一些Jdbc的操作封装来简化数据查询和记录读取操作。代码非常简洁,如果你厌烦了Hibernate的庞大,不妨可以试试——DbUtils。-The Commons DbUtils library is a small set of classes designed to make working with JDBC easier. JDBC resource cleanup code is mundane, error prone work so these classes abstract out all of the cleanup tasks from your code leaving you with what you really wanted to do with JDBC in the first place: query and update data.

Description: 1 对于数据表的读操作 他可以把结果转换成List Array Set等java集合 便于程序员操作;
2 对于数据表的写操作 也变得很简单(只需写sql语句)
3 可以使用数据源 使用JNDI 数据库连接池等技术来优化性能 重用已经构建好的数据库连接对象 而不像php asp那样 费时费力的不断重复的构建和析构这样的对象
DBUtils包括3个包:
org apache commons dbutils
org apache commons dbutils handlers
org apache commons dbutils wrappers
DBUtils封装了对JDBC的操作 简化了JDBC操作 可以少写代码
org apache commons dbutils
DbUtils 关闭链接等操作-1 For a read operation data table, he can convert the result into List Array Set and other easy to set java programmer operation 2 For writes data table has become very simple (just write sql statement) 3 can use a data source using JNDI connection pool technology to optimize the performance of reuse connection objects have been constructed rather than php asp as laborious repeated such objects DBUtils construction and destructor includes three packages: org apache commons dbutils org apache commons dbutils handlers org apache commons dbutils wrappers DBUtils encapsulates JDBC operation simplifies JDBC operations can write less code that org apache commons dbutils DbUtils close links and other operations Platform: |

Description: DBUtils提供了一个接口ResultSetHandler,它就是用来ResultSet转换成目标类型的工具。你可以自己去实现这个接口,把ResultSet转换成你想要的类型。
DBUtils提供了很多个ResultSetHandler接口的实现,这些实现已经基本够用了,我们通常不用自己去实现ResultSet接口了(DBUtils provides an interface ResultSetHandler, which is a tool used to convert ResultSet into a target type. You can implement this interface by yourself and convert the ResultSet into the type you want.
DBUtils provides many implementations of ResultSetHandler interfaces that are basically enough, and we usually do not have to implement the ResultSet interface ourselves) Platform: |
