A RESTful web service written based on JAX-WS that returns xml documents. This xml document can be generated based on JAXB annotations, simplifying xml generation. In order to use the dependent libraries, you can add the following dependencies in the pom.xml file of the maven project: <dependency> <groupId>jakarta.xml.ws</groupId> <artifactId>jakarta.xml.ws-api</artifactId> <version>4.0.0</version> </dependency> <dependency> <groupId>com.sun.xml.ws</groupId> <artifactId>jaxws-rt</artifactId> <version>4.0.0</version> […]

mybatis handles one-to-many, many-to-one, many-to-many relationships, annotations and xml file writing
Zero, Preface This article is used to study one-to-many, many-to-one, and many-to-many relationships between tables and objects. Two methods of xml file configuration and annotation configuration were studied Super complete~ The entities used for research are students, teachers, courses Note: The relationship between students and teachers should be many-to-many. This article uses many-to-one, that is, […]

Basic introduction: Configure beans based on annotations, mainly components in project development, such as Action, Service, and Dao. 2. Commonly used component annotation forms are: @Component indicates that the current annotation identifies a component. @Controller indicates that the current annotation identifies a controller, […]
Chapter 16 Reflections and Annotations
Through the Java reflection mechanism, you can access the description of the Java object that has been loaded into the JVM in the program, and realize the function of accessing, detecting and modifying the information describing the Java object itself. The Java reflection mechanism is very powerful, and support for this function is provided in […]
