Use spring's jmx annotation to get Pojo objects out to JMX

Since JDK5.0 introduced annotations (Annotation), Java development has been simplified a lot, allowing developers to almost get rid of complex

Trouble with configuration files. This article describes the set of annotations that spring provides equivalent to the Commons Attribut attribute class and the implementation class annotationsjmxattributesource of a policy interface jmxattributesource that allows Mbeaninfoassembler to read these notes. This article shows you how to quickly and easily get Pojo objects out to JMX using the spring jmx annotation.

Inside the appearance of the function of the class name, described below, first look at an example:

Write a Pojo object first

2 Import java.util.List;
