Class AbstractConfiguredSecurityBuilder<O,B extends SecurityBuilder<O>>

java.lang.Object

org.springframework.security.config.annotation.AbstractSecurityBuilder<O>

org.springframework.security.config.annotation.AbstractConfiguredSecurityBuilder<O,B>

Type Parameters:

O - The object that this builder returns

B - The type of this builder (that is returned by the base class)

All Implemented Interfaces:

SecurityBuilder<O>

Direct Known Subclasses:

AuthenticationManagerBuilder, HttpSecurity, WebSecurity

public abstract class AbstractConfiguredSecurityBuilder<O,B extends SecurityBuilder<O>>
extends AbstractSecurityBuilder<O>

A base SecurityBuilder that allows SecurityConfigurer to be applied to it. This makes modifying the SecurityBuilder a strategy that can be customized and broken up into a number of SecurityConfigurer objects that have more specific goals than that of the SecurityBuilder.

For example, a SecurityBuilder may build an DelegatingFilterProxy, but a SecurityConfigurer might populate the SecurityBuilder with the filters necessary for session management, form based login, authorization, etc.

Constructor Details

AbstractConfiguredSecurityBuilder

protected AbstractConfiguredSecurityBuilder(ObjectPostProcessor<Object> objectPostProcessor)

Creates a new instance with the provided ObjectPostProcessor. This post processor must support Object since there are many types of objects that may be post processed.

Parameters:

objectPostProcessor - the ObjectPostProcessor to use

AbstractConfiguredSecurityBuilder

protected AbstractConfiguredSecurityBuilder(ObjectPostProcessor<Object> objectPostProcessor,
 boolean allowConfigurersOfSameType)

Creates a new instance with the provided ObjectPostProcessor. This post processor must support Object since there are many types of objects that may be post processed.

Parameters:

objectPostProcessor - the ObjectPostProcessor to use

allowConfigurersOfSameType - if true, will not override other SecurityConfigurer's when performing apply

Method Details

getOrBuild

public O getOrBuild()

Similar to AbstractSecurityBuilder.build() and AbstractSecurityBuilder.getObject() but checks the state to determine if AbstractSecurityBuilder.build() needs to be called first.

Returns:

the result of AbstractSecurityBuilder.build() or AbstractSecurityBuilder.getObject(). If an error occurs while building, returns null.

apply

public <C extends SecurityConfigurerAdapter<O,
B>> C apply(C configurer)
                                                   throws Exception

Applies a SecurityConfigurerAdapter to this SecurityBuilder and invokes SecurityConfigurerAdapter.setBuilder(SecurityBuilder).

Parameters:

configurer -

Returns:

the SecurityConfigurerAdapter for further customizations

Throws:

Exception

apply

public <C extends SecurityConfigurer<O,
B>> C apply(C configurer)
                                            throws Exception

Applies a SecurityConfigurer to this SecurityBuilder overriding any SecurityConfigurer of the exact same class. Note that object hierarchies are not considered.

Parameters:

configurer -

Returns:

the SecurityConfigurerAdapter for further customizations

Throws:

Exception

setSharedObject

public <C> void setSharedObject(Class<C> sharedType,
 C object)

Sets an object that is shared by multiple SecurityConfigurer.

Parameters:

sharedType - the Class to key the shared object by.

object - the Object to store

getSharedObject

public <C> C getSharedObject(Class<C> sharedType)

Gets a shared Object. Note that object heirarchies are not considered.

Parameters:

sharedType - the type of the shared Object

Returns:

the shared Object or null if it is not found

getSharedObjects

public Map<Class<?>,Object> getSharedObjects()

Gets the shared objects

Returns:

the shared Objects

getConfigurers

public <C extends SecurityConfigurer<O,
B>> List<C> getConfigurers(Class<C> clazz)

Gets all the SecurityConfigurer instances by its class name or an empty List if not found. Note that object hierarchies are not considered.

Parameters:

clazz - the SecurityConfigurer class to look for

Returns:

a list of SecurityConfigurers for further customization

removeConfigurers

public <C extends SecurityConfigurer<O,
B>> List<C> removeConfigurers(Class<C> clazz)

Removes all the SecurityConfigurer instances by its class name or an empty List if not found. Note that object hierarchies are not considered.

Parameters:

clazz - the SecurityConfigurer class to look for

Returns:

a list of SecurityConfigurers for further customization

getConfigurer

public <C extends SecurityConfigurer<O,
B>> C getConfigurer(Class<C> clazz)

Returns:

the SecurityBuilder for further customizations

postProcess

protected <P> P postProcess(P object)

Performs post processing of an object. The default is to delegate to the ObjectPostProcessor.

Parameters:

object - the Object to post process

Returns:

the possibly modified Object to use

doBuild

protected final O doBuild()
                   throws Exception

Executes the build using the SecurityConfigurer's that have been applied using the following steps:

• Invokes beforeInit() for any subclass to hook into
• Invokes SecurityConfigurer.init(SecurityBuilder) for any SecurityConfigurer that was applied to this builder.
• Invokes beforeConfigure() for any subclass to hook into
• Invokes performBuild() which actually builds the Object

Specified by:

doBuild in class AbstractSecurityBuilder<O>

Exception - if an error occurs

beforeInit

protected void beforeInit()

Invoked prior to invoking each SecurityConfigurer.configure(SecurityBuilder) method. Subclasses may override this method to hook into the lifecycle without using a SecurityConfigurer.

Exception

performBuild

protected abstract O performBuild()
                           throws Exception

the Object to be buit or null if the implementation allows it

Throws:

Exception
