Spring Hibernate Config: mappingDirectoryLocations

java光环 — Wed, 20 Apr 2005 05:59:00 GMT

I have seen a bunch of projects which are using Spring and Hibernate, and have something like the following in their applicationContext.xml file.

<property name="mappingResources">
<list>
<value>com/almaer/model/Person.hbm.xmlvalue>
<value>com/almaer/model/Car.hbm.xmlvalue>
<value>com/almaer/model/Engine.hbm.xmlvalue>
<value>com/almaer/model/Toy.hbm.xmlvalue>
list>
property>

Luckily, you can just point to the directory now, and have Spring work it out for you :)

<property name="mappingDirectoryLocations">
<list>
<value>WEB-INF/mappingsvalue>
list>
property>

How do you use findByNamedParam，findByNamedQueryAndNamedParam？

java光环 — Thu, 14 Apr 2005 11:31:00 GMT

spring 封装了对hibernate 底层操作，现列了一些查询方法：

1,findByNamedParam
code:

public List getRolesByName(String roleName) {
return getHibernateTemplate().findByNamedParam("from Role role where role.name=:roleName", "roleName",roleName);
}

2,findByNamedQueryAndNamedParam
code:

getHibernateTemplate().findByNamedQueryAndNamedParam("testeCQuery", "idCidade", cidade);

xml code:

<query name="testeCQuery">
from br.com.ag2.casarural.vo.Cidade as cidade where cidade.idCidade = :idCidade
]]>query>
