Assignment “Digital Signal Processing” gives a certain set of digital signals. In addition to the target signal, the signal is also mixed with strong noise, but the frequency of the noise and the target signal does not overlap. It is required to use the knowledge learned this semester to analyze the signal. at

BeanNotOfRequiredTypeException: Remember the tomcat service startup error caused by an improper dubbo reference
When deploying the service this afternoon, I found that the tomcat service could not be started. Exception: org.springframework.beans.factory.BeanCreationException:Error creating bean with name ‘manageFeeController’: Injection of resource dependencies failed. That is to say, the container failed to create the bean due to resource injection problems. Looking further back, this BeanCreation exception was caused by this error: […]

Front-end skinning solution – element + less touchless skinning (no page refresh required) Foreword Not long ago, when revamping a project that had been iterated for more than a year, a skin-changing function was added. Through my own exploration, I have summarized a set of more suitable transformation plans for your reference. If you have […]
