Class MapBasedMethodSecurityMetadataSource

java.lang.Object
  org.springframework.security.access.method.AbstractMethodSecurityMetadataSource
      org.springframework.security.access.method.AbstractFallbackMethodSecurityMetadataSource
          org.springframework.security.access.method.MapBasedMethodSecurityMetadataSource

All Implemented Interfaces:

AopInfrastructureBean, BeanClassLoaderAware, MethodSecurityMetadataSource, SecurityMetadataSource

public class MapBasedMethodSecurityMetadataSource
extends AbstractFallbackMethodSecurityMetadataSource
implements BeanClassLoaderAware

Stores a list of ConfigAttributes for a method or class signature.

This class is the preferred implementation of MethodSecurityMetadataSource for XML-based definition of method security metadata. To assist in XML-based definition, wildcard support is provided.

MapBasedMethodSecurityMetadataSource

public MapBasedMethodSecurityMetadataSource()

MapBasedMethodSecurityMetadataSource

public MapBasedMethodSecurityMetadataSource(Map<String,List<ConfigAttribute>> methodMap)

Creates the MapBasedMethodSecurityMetadataSource from a

Parameters:

methodMap - map of method names to ConfigAttributes.

Method Detail

findAttributes

protected Collection<ConfigAttribute> findAttributes(Class<?> clazz)

Implementation does not support class-level attributes.

Specified by:

findAttributes in class AbstractFallbackMethodSecurityMetadataSource

Parameters:

clazz - the target class for the invocation (never null)

Returns:

the security metadata (or null if no metadata applies)

findAttributes

protected Collection<ConfigAttribute> findAttributes(Method method,
                                                     Class<?> targetClass)

Will walk the method inheritance tree to find the most specific declaration applicable.

Specified by:

findAttributes in class AbstractFallbackMethodSecurityMetadataSource

Parameters:

method - the method for the current invocation (never null)

targetClass - the target class for the invocation (may be null)

Returns:

the security metadata (or null if no metadata applies)

addSecureMethod

public void addSecureMethod(Class<?> javaType,
                            String mappedName,
                            List<ConfigAttribute> attr)

Add configuration attributes for a secure method. Mapped method names can end or start with * for matching multiple methods.

Parameters:

javaType - target interface or class the security configuration attribute applies to

mappedName - mapped method name, which the javaType has declared or inherited

attr - required authorities associated with the method

addSecureMethod

public void addSecureMethod(Class<?> javaType,
                            Method method,
                            List<ConfigAttribute> attr)

Adds configuration attributes for a specific method, for example where the method has been matched using a pointcut expression. If a match already exists in the map for the method, then the existing match will be retained, so that if this method is called for a more general pointcut it will not override a more specific one which has already been added. This

getAllConfigAttributes

public Collection<ConfigAttribute> getAllConfigAttributes()

Obtains the configuration attributes explicitly defined against this bean.

Specified by:

getAllConfigAttributes in interface SecurityMetadataSource

Returns:

the attributes explicitly defined against this bean

setBeanClassLoader

public void setBeanClassLoader(ClassLoader beanClassLoader)

Specified by:

setBeanClassLoader in interface BeanClassLoaderAware

getMethodMapSize

public int getMethodMapSize()

Returns:

map size (for unit tests and diagnostics)
