public class FileSystemXmlApplicationContext
extends AbstractXmlApplicationContext

Standalone XML application context, taking the context definition files from the file system or from URLs, interpreting plain paths as relative file system locations (e.g. "mydir/myfile.txt"). Useful for test harnesses as well as for standalone environments.

NOTE: Plain paths will always be interpreted as relative to the current VM working directory, even if they start with a slash. (This is consistent with the semantics in a Servlet container.) Use an explicit "file:" prefix to enforce an absolute file path.

The config location defaults can be overridden via getConfigLocations(), Config locations can either denote concrete files like "/myfiles/context.xml" or Ant-style patterns like "/myfiles/*-context.xml" (see the AntPathMatcher javadoc for pattern details).

Note: In case of multiple config locations, later bean definitions will override ones defined in earlier loaded files. This can be leveraged to deliberately override certain bean definitions via an extra XML file.

This is a simple, one-stop shop convenience ApplicationContext. Consider using the GenericApplicationContext class in combination with an XmlBeanDefinitionReader for more flexible context setup.

Constructor Detail

FileSystemXmlApplicationContext

public FileSystemXmlApplicationContext(String configLocation)
                                throws BeansException
Create a new FileSystemXmlApplicationContext, loading the definitions from the given XML file and automatically refreshing the context.

Parameters:
configLocation - file path
Throws:
BeansException - if context creation failed

FileSystemXmlApplicationContext

public FileSystemXmlApplicationContext(String[] configLocations)
                                throws BeansException
Create a new FileSystemXmlApplicationContext, loading the definitions from the given XML files and automatically refreshing the context.

Parameters:
configLocations - array of file paths
Throws:
BeansException - if context creation failed

FileSystemXmlApplicationContext

public FileSystemXmlApplicationContext(String[] configLocations,
                                       ApplicationContext parent)
                                throws BeansException
Create a new FileSystemXmlApplicationContext with the given parent, loading the definitions from the given XML files and automatically refreshing the context.

Parameters:
configLocations - array of file paths
parent - the parent context
Throws:
BeansException - if context creation failed

FileSystemXmlApplicationContext

public FileSystemXmlApplicationContext(String[] configLocations,
                                       boolean refresh)
                                throws BeansException
Create a new FileSystemXmlApplicationContext, loading the definitions from the given XML files.

Parameters:
configLocations - array of file paths
refresh - whether to automatically refresh the context, loading all bean definitions and creating all singletons. Alternatively, call refresh manually after further configuring the context.
Throws:
BeansException - if context creation failed
See Also:
AbstractApplicationContext.refresh()

FileSystemXmlApplicationContext

public FileSystemXmlApplicationContext(String[] configLocations,
                                       boolean refresh,

                                throws BeansException
Create a new FileSystemXmlApplicationContext with the given parent, loading the definitions from the given XML files.

Parameters:

AbstractApplicationContext.refresh()
Method Detail

getConfigLocations

protected String[] getConfigLocations()
Description copied from class: AbstractXmlApplicationContext
Return an array of resource locations, referring to the XML bean definition files that this context should be built with. Can also include location patterns, which will get resolved via a ResourcePatternResolver.

The default implementation returns null. Subclasses can override this to provide a set of resource locations to load bean definitions from.

Overrides:
getConfigLocations in class AbstractXmlApplicationContext
Returns:
an array of resource locations, or null if none
See Also:
AbstractApplicationContext.getResources(java.lang.String), AbstractApplicationContext.getResourcePatternResolver()

getResourceByPath

protected Resource getResourceByPath(String path)
Resolve resource paths as file system paths.

Note: Even if a given path starts with a slash, it will get interpreted as relative to the current VM working directory. This is consistent with the semantics in a Servlet container.

Overrides:
getResourceByPath in class DefaultResourceLoader
Parameters:
path - path to the resource
Returns:
Resource handle

AbstractRefreshableWebApplicationContext.getResourceByPath(java.lang.String)
