Spring new annotation (0 configuration annotation) With this set of annotations, no XML files are required throughout the spring development process. @Co

Method for Spring MVC Annotation verification, mvcannotation Introduction The Annotation verification of Spring MVC can directly verify the simple data of the view model. Note that this is simple. If the data verification of the model requires complicated business logic, it is difficult to use

order in which the Aroundadvice, Beforeadvice, Afteradvice, Returningadvice are executed is determined by the order of the annotations. But sometimes the order is changed, and the result is not changed, possibly because of the cache. I had this problem a few days ago, but I tested it again today and found that the order of execution was consistent with the order of the annotations.Both XML and Annotation annotations can be configured as configuration

the source code and recompile before you can implement the adjustment. If the Bean is not a class written by itself (such as JdbcTemplate, Sessionfactorybean, etc.), the annotation configuration will not be implemented, and the XML configuration is the only available way. note configurations tend to be class-level, while XML configurations can be more flexible. For example, transaction configurations using

Spring,mybatis Transaction Management configuration and @transactional annotation usageOverviewTransaction management is critical for enterprise applications, and it guarantees data consistency even in the event of an exception.The Spring framework provides a consistent abstraction of transaction management, with the following characteristics: Provides a

Spring's dependency check function can only check all attributes of Certain types. It cannot only check specific attributes and is not flexible enough. Generally, we only need to check whether specific attributes are set, rather than all attributes of a specific type. Requiredannotationbeanpostprocessor is a post-processor of spring bean. It checks whether all bean attributes with the @ required annotation

We will habitually negotiate context: annotation-config in the Spring configuration file. Today we will study the role of this configuration. From the http://www.springframework.org/schema/context/spring-context-3.0.xsd we found Spring 3.0's explanation of this annotation:
