Where is persistence xml file

However, if you want to explicitly set the entity classes to be be used, and exclude any other entity classes found on the current Java classpath, then you need to set the exclude-unlisted-classes element to the value of true :. After setting the exclude-unlisted-classes XML element above, you need to specify the list of entity classes registered by the current Persistence Unit via the class XML element:. The vast majority of JPA and Hibernate applications use annotations to build the object-relational mapping metadata.

However, even if you are using annotations, you can still use XML mappings to override the static annotation metadata with the one provided via an orm. By default, the orm. If you want to use a different file location, you can use the mapping-file XML element in the persistence. If you want to provide one or more JAR files to be scanned, you can use the jar-file element, like this:. The shared-cache-mode element allows you to define the SharedCacheMode strategy for storing entities in the second-level cache, and it can take one of the following values:.

You can also override the shared-cache-mode strategy programmatically using the javax. You can also override the validation-mode strategy programmatically using the javax. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams?
