Question

我正在尝试评估某些表达式，这些表达式正在比较两个日期，然后在某些字段中添加值作为结果。

例如，[${Submission Date} != null] ? ([${Submission Date} > ${Due Date}] ..然后sum(${30},${83030},${4040},${83040})

当我重新启动tomcat(version: 8.5.24)时，我在2秒内从SpelExpression.getValue()函数得到结果，但每当我重新提交时再次调用相同的request( SpelExpression.getValue()时，时间从2开始增加到4到5到6 ......它会继续增加。

在其中一个生产服务器中，我发现这个函数的响应在10分钟内完成，当我重新启动tomcat时，一切都运行正常，因为前几个请求。应用日志后，我发现这个getValue()函数是罪魁祸首。

我正在使用Spring 4和java 7。

为什么这个功能会随着时间的推移而变慢？

以下是表达式：

@expressionEvaluatorService.evaluateSubExpression(#expr1,#params,#entityContext,#errorConditions,#entityFields) ? (@expressionEvaluatorService.evaluateSubExpression(#expr2,#params,#entityContext,#errorConditions,#entityFields) ? T(com.sirionlabs.service.ExpressionEvaluatorServiceImpl).duration(#F1047,#med41806) :  T(com.sirionlabs.service.ExpressionEvaluatorServiceImpl).duration(#F1046,#med41806) ) :  (@expressionEvaluatorService.evaluateSubExpression(#expr3,#params,#entityContext,#errorConditions,#entityFields) ? T(com.sirionlabs.service.ExpressionEvaluatorServiceImpl).duration(#F1047,#med41806): 0)

和上下文是：

Answer 1

我最终找到了一个解决方案，我使用4.0.0版本的弹簧版本有一个错误.RELEASE，我将它升级到4.0.2并且工作正常。
