Constructor Detail

MethodMapTransactionAttributeSource

public MethodMapTransactionAttributeSource()

Method Detail

setMethodMap

public void setMethodMap(Map methodMap)

Set a name/attribute map, consisting of "FQCN.method" method names (e.g. "com.mycompany.mycode.MyClass.myMethod") and TransactionAttribute instances (or Strings to be converted to TransactionAttribute instances).

Intended for configuration via setter injection, typically within a Spring bean factory. Relies on afterPropertiesSet() being called afterwards.

Parameters:

methodMap - said Map from method name to attribute value

See Also:

TransactionAttribute, TransactionAttributeEditor

---

setBeanClassLoader

public void setBeanClassLoader(ClassLoader beanClassLoader)

Description copied from interface: BeanClassLoaderAware

Callback that supplies the bean class loader to a bean instance.

Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean's InitializingBean.afterPropertiesSet() method or a custom init-method.

Specified by:

setBeanClassLoader in interface BeanClassLoaderAware

Parameters:

beanClassLoader - the owning class loader; may be null in which case a default ClassLoader must be used, for example the ClassLoader obtained via ClassUtils.getDefaultClassLoader()

---

afterPropertiesSet

public void afterPropertiesSet()

Eagerly initializes the specified "methodMap", if any.

Specified by:

afterPropertiesSet in interface InitializingBean

See Also:

initMethodMap(java.util.Map)

---

initMethodMap

protected void initMethodMap(Map methodMap)

Initialize the specified "methodMap", if any.

Parameters:

methodMap - Map from method names to TransactionAttribute instances (or Strings to be converted to TransactionAttribute instances)

See Also:

setMethodMap(java.util.Map)

---

addTransactionalMethod

public void addTransactionalMethod(String name,
                                   TransactionAttribute attr)

Add an attribute for a transactional method.

Method names can end or start with "*" for matching multiple methods.

Parameters:

name - class and method name, separated by a dot

attr - attribute associated with the method

Throws:

IllegalArgumentException - in case of an invalid name

---

addTransactionalMethod

public void addTransactionalMethod(Class clazz,
                                   String mappedName,
                                   TransactionAttribute attr)

Add an attribute for a transactional method. Method names can end or start with "*" for matching multiple methods.

Parameters:

clazz - target interface or class

mappedName - mapped method name

attr - attribute associated with the method

---

addTransactionalMethod

public void addTransactionalMethod(Method method,
                                   TransactionAttribute attr)

Add an attribute for a transactional method.

Parameters:

method - the method

attr - attribute associated with the method

---

isMatch

protected boolean isMatch(String methodName,
                          String mappedName)

Return if the given method name matches the mapped name.

The default implementation checks for "xxx*", "*xxx" and "*xxx*" matches, as well as direct equality.

Parameters:

methodName - the method name of the class

mappedName - the name in the descriptor

Returns:

if the names match

See Also:

PatternMatchUtils.simpleMatch(String, String)

---

getTransactionAttribute

public TransactionAttribute getTransactionAttribute(Method method,
                                                    Class targetClass)

Description copied from interface: TransactionAttributeSource

Return the transaction attribute for this method. Return null if the method is non-transactional.

Specified by:

getTransactionAttribute in interface TransactionAttributeSource

Parameters:

method - method

targetClass - target class. May be null, in which case the declaring class of the method must be used.

Returns:

TransactionAttribute the matching transaction attribute, or null if none found

---

equals

public boolean equals(Object other)

Overrides:

equals in class Object

---

hashCode

public int hashCode()

Overrides:

hashCode in class Object

---

toString

public String toString()

Overrides:

toString in class Object
