IniWebEnvironment

public IniWebEnvironment()

Method Detail

init

public void init()

Initializes this instance by resolving any potential (explicit or resource-configured) Ini configuration and calling configure for actual instance configuration.

Specified by:

init in interface org.apache.shiro.util.Initializable

parseConfig

protected org.apache.shiro.config.Ini parseConfig()

Loads configuration Ini from ResourceBasedWebEnvironment.getConfigLocations() if set, otherwise falling back to the getDefaultConfigLocations(). Finally any Ini objects will be merged with the value returned from getFrameworkIni()

Returns:

Ini configuration to be used by this Environment.

Since:

1.4

configure

protected void configure()

getFrameworkIni

protected org.apache.shiro.config.Ini getFrameworkIni()

Extension point to allow subclasses to provide an Ini configuration that will be merged into the users configuration. The users configuration will override anything set here.

NOTE: Framework developers should use with caution. It is possible a user could provide configuration that would conflict with the frameworks configuration. For example: if this method returns an Ini object with the following configuration:

     [main]
     realm = com.myco.FoobarRealm
     realm.foobarSpecificField = A string
 

And the user provides a similar configuration:

     [main]
     realm = net.differentco.MyCustomRealm
 

This would merge into:

     [main]
     realm = net.differentco.MyCustomRealm
     realm.foobarSpecificField = A string
 

This may cause a configuration error if MyCustomRealm does not contain the field foobarSpecificField. This can be avoided if the Framework Ini uses more unique names, such as foobarRealm. which would result in a merged configuration that looks like:

     [main]
     foobarRealm = com.myco.FoobarRealm
     foobarRealm.foobarSpecificField = A string
     realm = net.differentco.MyCustomRealm
 

Returns:

Ini configuration used by the framework integrations.

getSpecifiedIni

protected org.apache.shiro.config.Ini getSpecifiedIni(String[] configLocations)
                                               throws org.apache.shiro.config.ConfigurationException

Throws:

org.apache.shiro.config.ConfigurationException

mergeIni

protected org.apache.shiro.config.Ini mergeIni(org.apache.shiro.config.Ini ini1,
                                               org.apache.shiro.config.Ini ini2)

getDefaultIni

protected org.apache.shiro.config.Ini getDefaultIni()

createIni

protected org.apache.shiro.config.Ini createIni(String configLocation,
                                                boolean required)
                                         throws org.apache.shiro.config.ConfigurationException

Creates an Ini instance reflecting the specified path, or null if the path does not exist and is not required.

If the path is required and does not exist or is empty, a ConfigurationException will be thrown.

Parameters:

configLocation - the resource path to load into an Ini instance.

required - if the path must exist and be converted to a non-empty Ini instance.

Returns:

an Ini instance reflecting the specified path, or null if the path does not exist and is not required.

Throws:

org.apache.shiro.config.ConfigurationException - if the path is required but results in a null or empty Ini instance.

createFilterConfiguration

protected ShiroFilterConfiguration createFilterConfiguration()

createFilterChainResolver

protected FilterChainResolver createFilterChainResolver()

createWebSecurityManager

protected WebSecurityManager createWebSecurityManager()

getDefaultConfigLocations

protected String[] getDefaultConfigLocations()

Returns an array with two elements, /WEB-INF/shiro.ini and classpath:shiro.ini.

Returns:

an array with two elements, /WEB-INF/shiro.ini and classpath:shiro.ini.

getIni

public org.apache.shiro.config.Ini getIni()

Returns the Ini instance reflecting this WebEnvironment's configuration.

Returns:

the Ini instance reflecting this WebEnvironment's configuration.

setIni

public void setIni(org.apache.shiro.config.Ini ini)

Allows for configuration via a direct Ini instance instead of via config locations.

If the specified instance is null or empty, the fallback/default resource-based configuration will be used.

Parameters:

ini - the ini instance to use for creation.

getDefaults

protected Map<String,Object> getDefaults()

getSecurityManagerFactory

protected WebIniSecurityManagerFactory getSecurityManagerFactory()

Returns the SecurityManager factory used by this WebEnvironment.

Returns:

the SecurityManager factory used by this WebEnvironment.

Since:

1.4

setSecurityManagerFactory

protected void setSecurityManagerFactory(WebIniSecurityManagerFactory factory)

Allows for setting the SecurityManager factory which will be used to create the SecurityManager.

Parameters:

factory - the SecurityManager factory to used.

Since:

1.4
