hibernate-4.x

问题 Here is my hibernate.cfg.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!-- Database connection settings --> <property name="connection.driver_class">com.mysql.jdbc.Driver</property> <property name="connection.url">jdbc:mysql://localhost:3306/sometable</property> <property name="connection

问题 I am facing problem with hibernate's explicit polymorphism. I used the polymorphism annotation and set it to explicit, but with get() and collections in mapped classes i always get all subclasses. I see all subclasses with left join in the hibernate "show_sql" output. What's the problem? Do I understand the documentation wrong? Or is it a bug in hibernate 4? I haven't seen any example with hibernate 4 and polymorphism annotation. sessionFactory.getCurrentSession().get(Node.class, 111); //

问题 Hi I am running a maven test using maven 3.0.3 with hibernate 4.0.0 Final release and spring 3.1 on jdk7 update 2. I get the following error.

问题 I have three kinds of primary keys for tables: INT auto generated primary key which use AUTO_INCREMENT capacity from database vendor (MySQL) CHAR(X) primary key to store a user readable value as key (where X is a number and 50 <= X <= 60) Complex primary keys, composed by 2 or 3 fields of the table.

问题 Question is not a duplicate as Hibernate is involved As the James' answer partially solved the problem, I accepted it and opened a new question, please follow up here I am trying to inject SessionFactory into a repository class; however, it looks like it does not work as the code returns NullPointer exception. I cleaned and rebuilt the project but the issue still exist. I also put @Autowired on the setSessionFactory method but did not help. Interface public interface TestRep { public void get

问题 It seems like the hibernate3-maven-plugin used to generate DDL create/drop scripts is not compatible any more with Hibernate 4.3 and newer versions (using JPA 2.1 ). I use this plugin configuration : <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>hibernate3-maven-plugin</artifactId> <version>3.0</version> <executions> <execution> <id>generate-sql-schema</id> <phase>process-sources</phase> <goals> <goal>hbm2ddl</goal> </goals> <configuration> <hibernatetool> <jpaconfiguration

问题 I've just realized that there is no org.hibernate.cache.internal.NoCacheProvider class in Hibernate 4 Core packages. Maybe it is deprecated. So is there any alternive for Hibernate 4? Thank you in advance! 回答1: CacheProvider SPI has been deprecated for quite a long time now (since 3.3 iirc). org.hibernate.cache.internal.NoCachingRegionFactory is the "no caching" equivalent in the new CacheRegionFactory SPI 来源： https://stackoverflow.com/questions/18825643/nocacheprovider-class-alternative-in
