equals	back to summary
public boolean equals(Object other) Overrides java.lang.Object.equals. Doc from java.lang.Object.equals. Indicates whether some other object is "equal to" this one. The `equals` method implements an equivalence relation on non-null object references: It is reflexive: for any non-null reference value `x`, `x.equals(x)` should return `true`. It is symmetric: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`. It is transitive: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`. It is consistent: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified. For any non-null reference value `x`, `x.equals(null)` should return `false`. An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes. Parameters other:Object the reference object with which to compare. Returns:boolean `true` if this object is the same as the obj argument; `false` otherwise. Annotations @Override

public boolean equals(Object other)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

It is reflexive: for any non-null reference value x, x.equals(x) should return true.
It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters

other:Object: the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

hashCode back to summary

hashCode	back to summary
public int hashCode() Overrides java.lang.Object.hashCode. Doc from java.lang.Object.hashCode. Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by `java.util.HashMap`. The general contract of `hashCode` is: Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application. If two objects are equal according to the `equals` method, then calling the `hashCode` method on each of the two objects must produce the same integer result. It is not required that if two objects are unequal according to the `equals` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables. Returns:int a hash code value for this object.

isCandidateClass	back to summary
public boolean isCandidateClass(Class<?> targetClass) Overrides default org.springframework.transaction.annotation.TransactionAnnotationParser.isCandidateClass. Doc from org.springframework.transaction.annotation.TransactionAnnotationParser.isCandidateClass. Determine whether the given class is a candidate for transaction attributes in the annotation format of this `TransactionAnnotationParser`. If this method returns `false`, the methods on the given class will not get traversed for `#parseTransactionAnnotation` introspection. Returning `false` is therefore an optimization for non-affected classes, whereas `true` simply means that the class needs to get fully introspected for each method on the given class individually. Parameters targetClass:Class<?> the class to introspect Returns:boolean `false` if the class is known to have no transaction annotations at class or method level; `true` otherwise. The default implementation returns `true`, leading to regular introspection. Annotations @Override

Determine whether the given class is a candidate for transaction attributes in the annotation format of this TransactionAnnotationParser.

If this method returns false, the methods on the given class will not get traversed for #parseTransactionAnnotation introspection. Returning false is therefore an optimization for non-affected classes, whereas true simply means that the class needs to get fully introspected for each method on the given class individually.

Parameters

targetClass:Class<?>: the class to introspect

Returns:boolean

false if the class is known to have no transaction annotations at class or method level; true otherwise. The default implementation returns true, leading to regular introspection.

public TransactionAttribute parseTransactionAnnotation(AnnotatedElement element) Implements org.springframework.transaction.annotation.TransactionAnnotationParser.parseTransactionAnnotation. Doc from org.springframework.transaction.annotation.TransactionAnnotationParser.parseTransactionAnnotation. Parse the transaction attribute for the given method or class, based on an annotation type understood by this parser. This essentially parses a known transaction annotation into Spring's metadata attribute class. Returns `null` if the method/class is not transactional. Parameters element:AnnotatedElement the annotated method or class Returns:TransactionAttribute the configured transaction attribute, or `null` if none found Annotations @Override @Nullable

public boolean rollbackOn(Throwable ex) Overrides org.springframework.transaction.interceptor.DefaultTransactionAttribute.rollbackOn. Implements org.springframework.transaction.interceptor.TransactionAttribute.rollbackOn. Doc from org.springframework.transaction.interceptor.DefaultTransactionAttribute.rollbackOn. The default behavior is as with EJB: rollback on unchecked exception (`RuntimeException`), assuming an unexpected outcome outside any business rules. Additionally, we also attempt to rollback on `Error` which is clearly an unexpected outcome as well. By contrast, a checked exception is considered a business exception and therefore a regular expected outcome of the transactional business method, i.e. a kind of alternative return value which still allows for regular completion of resource operations. This is largely consistent with TransactionTemplate's default behavior, except that TransactionTemplate also rolls back on undeclared checked exceptions (a corner case). For declarative transactions, we expect checked exceptions to be intentionally declared as business exceptions, leading to a commit by default.
