This article introduces the relevant knowledge of "the configuration method of transactions in F3.0". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

The first configuration method: transaction management based on XML

This method does not need to make any changes to the original business, and can be configured by defining the matching of methods that need to be intercepted in the XML file. The requirement is that the methods in the business processing should be named regularly, such as setXxx,xxxUpdate and so on. The detailed configuration is as follows:

Xml code

Tx:attributes > tx:advice > aop:config >

Configuration method in the second part: transaction management based on @ Transactional

In this way, you only need to define a transaction management object (such as DataSourceTransactionManager) in the Spring configuration file, then add a node, reference the transaction management object, and then use @ Transactional to mark the classes and methods that need to be transacted. Examples are as follows:

Spring configuration XML file

Xml code

@ Transactional example in Java code

Java code

/ * * @ author ZYWANG 2011-3-24 * / @ Service @ Transactional (propagation = Propagation.REQUIRED) public class TeacherServicesImpl implements TeacherServices {@ Autowired TeacherDao dao = null; public TeacherDao getDao () {return dao;} public void setDao (TeacherDao dao) {this.dao = dao } @ Override @ Transactional (readOnly=true,propagation=Propagation.NEVER) public List getAllTeachers () {return getDao () .getAllTeachers ();} @ Override public void addTeacher (Teacher teacher) {if (teacher.getId () > 0) {getDao () .updateTeacher (teacher) } else {getDao (). AddTeacher (teacher);} "how to configure transactions in F3.0" ends here. Thank you for reading.
