org.springframework.boot.logging.StandardStackTracePrinter

All Implemented Interfaces:

StackTracePrinter

public final class StandardStackTracePrinter
extends Object
implements StackTracePrinter

StackTracePrinter that prints a standard form stack trace. This printer produces a result in a similar form to Throwable.printStackTrace(), but offers more customization options.

Since:

3.5.0

Method Summary

Modifier and Type	Method	Description
void	printStackTrace(Throwable throwable, Appendable out)	Prints a stack trace for the given Throwable.
static StandardStackTracePrinter	rootFirst()	Return a StandardStackTracePrinter that prints the stack trace with the root exception first (the opposite of Throwable.printStackTrace()).
static StandardStackTracePrinter	rootLast()	Return a StandardStackTracePrinter that prints the stack trace with the root exception last (the same as Throwable.printStackTrace()).
StandardStackTracePrinter	withCommonFrames()	Return a new StandardStackTracePrinter from this one that will print all common frames rather the replacing them with the "... N more" message.
StandardStackTracePrinter	withFilter(Predicate<Throwable> predicate)	Return a new StandardStackTracePrinter from this one that will only include throwables (excluding caused and suppressed) that match the given predicate.
StandardStackTracePrinter	withFormatter(Function<Throwable,String> formatter)	Return a new StandardStackTracePrinter from this one uses the specified formatter to create a string representation of a throwable.
StandardStackTracePrinter	withFrameFilter(BiPredicate<Integer,StackTraceElement> predicate)	Return a new StandardStackTracePrinter from this one that will only include frames that match the given predicate.
StandardStackTracePrinter	withFrameFormatter(Function<StackTraceElement,String> frameFormatter)	Return a new StandardStackTracePrinter from this one uses the specified formatter to create a string representation of a frame.
StandardStackTracePrinter	withHashes()	Return a new StandardStackTracePrinter from this one that generates and prints hashes for each stacktrace.
StandardStackTracePrinter	withHashes(boolean hashes)	Return a new StandardStackTracePrinter from this one that changes if hashes should be generated and printed for each stacktrace.
StandardStackTracePrinter	withHashes(ToIntFunction<StackTraceElement> frameHasher)
StandardStackTracePrinter	withLineSeparator(String lineSeparator)	Return a new StandardStackTracePrinter from this one that print the stack trace using the specified line separator.
StandardStackTracePrinter	withMaximumLength(int maximumLength)	Return a new StandardStackTracePrinter from this one that will use ellipses to truncate output longer that the specified length.
StandardStackTracePrinter	withMaximumThrowableDepth(int maximumThrowableDepth)	Return a new StandardStackTracePrinter from this one that filter frames (including caused and suppressed) deeper then the specified maximum.
StandardStackTracePrinter	withoutSuppressed()	Return a new StandardStackTracePrinter from this one that will not print suppressed items.

Description copied from interface: StackTracePrinter

Prints a stack trace for the given Throwable.

Specified by:

printStackTrace in interface StackTracePrinter

throwable - the throwable that should have its stack trace printed

out - the destination to write output

Throws:

IOException - on IO error

withCommonFrames

public StandardStackTracePrinter withCommonFrames()

Returns:

a new StandardStackTracePrinter instance

withoutSuppressed

public StandardStackTracePrinter withoutSuppressed()

Return a new StandardStackTracePrinter from this one that will not print suppressed items.

Returns:

a new StandardStackTracePrinter instance

withMaximumLength

public StandardStackTracePrinter withMaximumLength(int maximumLength)

Parameters:

maximumLength - the maximum length that can be printed

Returns:

a new StandardStackTracePrinter instance

withMaximumThrowableDepth

public StandardStackTracePrinter withMaximumThrowableDepth(int maximumThrowableDepth)

Return a new StandardStackTracePrinter from this one that filter frames (including caused and suppressed) deeper then the specified maximum.

Parameters:

maximumThrowableDepth - the maximum throwable depth

Returns:

a new StandardStackTracePrinter instance

withFilter

public StandardStackTracePrinter withFilter(Predicate<Throwable> predicate)
