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 Detail

AbstractConfiguredSecurityBuilder

protected AbstractConfiguredSecurityBuilder(ObjectPostProcessor<java.lang.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<java.lang.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 Detail

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 java.lang.Exception

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

Parameters:

configurer -

Returns:

the SecurityConfigurerAdapter for further customizations

Throws:

java.lang.Exception

apply

public <C extends SecurityConfigurer<O,B>> C apply(C configurer)
                                            throws java.lang.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:

java.lang.Exception

setSharedObject

public <C> void setSharedObject(java.lang.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(java.lang.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 java.util.Map<java.lang.Class<?>,java.lang.Object> getSharedObjects()

Specified by:

doBuild in class AbstractSecurityBuilder<O>
