所有已实现的接口:

InitializingBean

直接已知子类:

JndiObjectFactoryBean, JndiObjectTargetSource

public abstract class JndiObjectLocator
extends JndiLocatorSupport
implements InitializingBean

Convenient superclass for JNDI-based service locators, providing configurable lookup of a specific JNDI resource.

Exposes a "jndiName" property. This may or may not include the "java:comp/env/" prefix expected by Jakarta EE applications when accessing a locally mapped (Environmental Naming Context) resource. If it doesn't, the "java:comp/env/" prefix will be prepended if the "resourceRef" property is true (the default is false) and no other scheme (e.g. "java:") is given.

Subclasses may invoke the lookup() method whenever it is appropriate. Some classes might do this on initialization, while others might do it on demand. The latter strategy is more flexible in that it allows for initialization of the locator before the JNDI object is available.

public JndiObjectLocator()

方法详细资料

setJndiName

public void setJndiName(@Nullable
 String jndiName)

Specify the JNDI name to look up. If it doesn't begin with "java:comp/env/" this prefix is added automatically if "resourceRef" is set to "true".

参数:

jndiName - the JNDI name to look up

另请参阅:

• JndiLocatorSupport.setResourceRef(boolean)

getJndiName

@Nullable
public String getJndiName()

Return the JNDI name to look up.

setExpectedType

public void setExpectedType(@Nullable
 Class<?> expectedType)

Specify the type that the located JNDI object is supposed to be assignable to, if any.

getExpectedType

@Nullable
public Class<?> getExpectedType()

Return the type that the located JNDI object is supposed to be assignable to, if any.

afterPropertiesSet

public void afterPropertiesSet()
                        throws IllegalArgumentException,
NamingException

指定者:

afterPropertiesSet 在接口中 InitializingBean

抛出:

IllegalArgumentException

NamingException

lookup

protected Object lookup()
                 throws NamingException

Perform the actual JNDI lookup for this locator's target resource.

返回:

the located target object

抛出:

NamingException - if the JNDI lookup failed or if the located JNDI object is not assignable to the expected type
