在Tomcat中部署spring时是否需要JTA TX管理器

Question

I have a web application, deployed in Tomcat. This app depends on one Spring pojo app jar, whcih is available in the classpath.

Spring POJO app, contains some DAO's and few services, I'm accessing these DAO's and services in web app as beans, by loading the spring context using ClassPathXMLApplicationContext.

The Serivces in Spring app also uses the DAOs , in which case both the apps accessing the same DB. Spring POJO app uses HibernateTransactionManager.

For this scenario, HibernateTXManager is good, or Do I need to gor JTA?

Answer 1

JTA is useful when you want to enlist two or more Datasources in the sam global transaction.

In your case you should have Services use DAOs and Web beans use Services , so this is just a Spring application design decision.

For connection pooling, I advice you take a look on HikariCP , which is probably the fastest one on the market .
