public class JamonPerformanceMonitorInterceptor
extends AbstractMonitoringInterceptor

Performance monitor interceptor that uses JAMon library to perform the performance measurement on the intercepted method and output the stats. In addition, it tracks/counts exceptions thrown by the intercepted method. The stack traces can be viewed in the JAMon web application.

This code is inspired by Thierry Templier's blog.

protected Object	invokeUnderTrace(MethodInvocation invocation, Log logger) Wraps the invocation with a JAMon Monitor and writes the current performance statistics to the log (if enabled).
protected boolean	isInterceptorEnabled(MethodInvocation invocation, Log logger) Always applies the interceptor if the "trackAllInvocations" flag has been set; else just kicks in if the log is enabled.
void	setTrackAllInvocations(boolean trackAllInvocations) Set whether to track all invocations that go through this interceptor, or just invocations with trace logging enabled.

JamonPerformanceMonitorInterceptor

public JamonPerformanceMonitorInterceptor()

Create a new JamonPerformanceMonitorInterceptor with a static logger.

JamonPerformanceMonitorInterceptor

public JamonPerformanceMonitorInterceptor(boolean useDynamicLogger)

Create a new JamonPerformanceMonitorInterceptor with a dynamic or static logger, according to the given flag.

参数:

useDynamicLogger - whether to use a dynamic logger or a static logger

另请参阅:

AbstractTraceInterceptor.setUseDynamicLogger(boolean)

JamonPerformanceMonitorInterceptor

public JamonPerformanceMonitorInterceptor(boolean useDynamicLogger,
                                          boolean trackAllInvocations)

Create a new JamonPerformanceMonitorInterceptor with a dynamic or static logger, according to the given flag.

参数:

useDynamicLogger - whether to use a dynamic logger or a static logger

trackAllInvocations - whether to track all invocations that go through this interceptor, or just invocations with trace logging enabled

另请参阅:

AbstractTraceInterceptor.setUseDynamicLogger(boolean)

方法详细资料

setTrackAllInvocations

public void setTrackAllInvocations(boolean trackAllInvocations)

Set whether to track all invocations that go through this interceptor, or just invocations with trace logging enabled.

Default is "false": Only invocations with trace logging enabled will be monitored. Specify "true" to let JAMon track all invocations, gathering statistics even when trace logging is disabled.

isInterceptorEnabled

protected boolean isInterceptorEnabled(MethodInvocation invocation,
                                       Log logger)

Always applies the interceptor if the "trackAllInvocations" flag has been set; else just kicks in if the log is enabled.

覆盖:

isInterceptorEnabled 在类中 AbstractTraceInterceptor

参数:

invocation - the MethodInvocation being traced

logger - the Log instance to check

另请参阅:

setTrackAllInvocations(boolean), AbstractTraceInterceptor.isLogEnabled(org.apache.commons.logging.Log)

invokeUnderTrace

protected Object invokeUnderTrace(MethodInvocation invocation,
                                  Log logger)
                           throws Throwable

Wraps the invocation with a JAMon Monitor and writes the current performance statistics to the log (if enabled).

指定者:

invokeUnderTrace 在类中 AbstractTraceInterceptor

logger - the Log to write trace messages to

返回:

the result of the call to MethodInvocation.proceed()

抛出:

Throwable - if the call to MethodInvocation.proceed() encountered any errors

trackException

protected void trackException(com.jamonapi.MonKey key,
                              Throwable ex)

Count the thrown exception and put the stack trace in the details portion of the key. This will allow the stack trace to be viewed in the JAMon web application.
