<! --
1. default-access = "field" Object attribute State setting
Property: indicates that this property needs to be bathed using the getter/settter method.
Default usage
2. package: Specify the package name of the class in this persistent configuration file.
Auto-import: Specify the import package
Default-lazy: Specifies the class delay loading policy in this persistent configuration file.
Default-cascade: Specifies the class cascade operation policy in the persistent configuration file.
<Class name = "Person" table = "t_person">
Dynamic-insert: attributes without values are not involved in the add operation.
True: properties without value assignment are not involved in the operation.
Mutable: indicates whether the class can be updated.
False: update is not allowed, but deletion can be added.
Select-before-update: true (an SQL query is initiated before the update is executed,


Check whether the data is inconsistent with the table. If the data is inconsistent, update the data. Otherwise, the data is not updated)
Where = "t_name = test2": A where query condition is attached before the query.
<Property name = "count" formula = "(select (*) from


T_Person) "/>
Query statement corresponding to formula, the data source of an attribute

<! -- Other property ing configurations of property
Name: Specifies the property name to be mapped in the persistence class.
Column: Specifies the column name of the table. If this parameter is left blank, the default attribute name is used)

Type: Specifies the column field type.

How to Implement Ant Construction Technology in Eclipse SDK and compile Junit test example

Eclipse has already integrated junit to directly create test cases.
Ant is also integrated
For more information, see the eclipse documentation.

Integrating ssh2 has encountered a problem and is easy to answer

When using servlet/jsp, you write a web. xml file. This is special and will automatically reload

However, spring, hibernate, and struts configurations
It won't reload

For SSH development, the test unit should be used for testing!
(I use JUnit4. You can use the test tool that comes with Spring to directly test SSH integration !)

Spring and hibernte also have Struts2.x
They do not depend on the web environment! (Struts2.x Action)
That is to say, you can not deploy them on Tomcat during development or testing !, Instead, use the main or test tool for encoding testing!

This is an SSH development method and part of spiral incremental development!
