When a bean is created, if the bean property is not initialized and assigned a value in the bean definition in the configuration file, spring will not initialize the property by default) check is not performed. However, in many cases, bean-specific attributes must be initialized and assigned values. In spring2.x, spring uses the dependency-check attribute in bean labels to set the method for force checks. T
processing, the purpose is to encapsulate data. 8.Servlet is how the request is handled usually when we send a request like Http://localhost:8080/TomcatTest/login, How does the container find the Loginservlet class to handle it? In fact, Tomcat has a mapper class that is designed to hold the child container information in the container container in Tomcat, Before the Org.apache.catalina.connector.Request class goes into the container container, Mapper will be based on this request hostname, C

Spring: Use Spring AOP to separate log input and method. spring AOP
Log output is a common function. The traditional method is to write the output statement inside the method body. When calling this method, use the input statement output information to record the execution of the method!

This is very annoying, on the one hand advocating high cohesion, low coupling, on the other hand, they did not integrate log4j on
Spring AOP is built on a dynamic agent basis, so spring's support for AOP is limited to method interception.By wrapping facets in the proxy class, spring weaves the slices into spring-managed beans at run time. as shown in 4.3, the proxy class encapsulates the target class and intercepts calls to the notified method and forwards the call to the true target bean.
