#Synopsis
A SQL convenience library for Java built on top of Hibernate
#Code Example
1. Load session factory configuration
Lets say you want to load hibernate configration file:
hibernate.dialect=org.hibernate.dialect.MySQLDialect
hibernate.connection.driver_class=com.mysql.jdbc.Driver
hibernate.connection.url=jdbc:mysql://localhost/test?useSSL=false&useUnicode=true&useJDBCCompliantTimezoneShift=true&useLegacyDatetimeCode=false&serverTimezone=UTC
hibernate.connection.username=root
hibernate.connection.password=123
hibernate.hbm2ddl.auto=update
hibernate.show_sql=true
hibernate.connection.pool_size=10
hibernate.jdbc.batch_size=25
hibernate.cache.use_second_level_cache=true
hibernate.cache.use_query_cache=true
hibernate.cache.region.factory_class=org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory
net.sf.ehcache.configurationResourceName=/ehcache.xml
hibernate.cache.use_structured_entries=false
hibernate.generate_statistics=true
You can do like this:
SessionFactoryProvider.getInstance()
.loader()
.context(Context.class)
.setProperties("hibernate_h2.properties")
.addAnnotatedClass(GameUser.class)
.load();2. Save a list of entities
List<GameUser> users = new ArrayList<>();
for(int i = 0 ; i < 5 ; i++) {
GameUser user = new GameUser();
user.setId(id ++);
user.setName("dungtv14#" + id);
user.setMoney(123456);
user.setLastLoginTime(new Date());
user.setLastLogoutTime(new Date());
user.setIp("1.2.3.4");
users.add(user);
}
new QueryExecutor().execute(Context.class, new SaveCollection().batchSize(3).entities(users));3. Fetch list of entities
List<GameUser> users = new QueryExecutor()
.execute(Context.class, new FetchListByEntity()
.entityType(GameUser.class)
.from(1)
.size(3));4. Fetch list of entities and sort to list of pages
List<Page> pages = new QueryExecutor()
.execute(Context.class, new FetchPagesByEntity()
.entityType(GameUser.class)
.from(1)
.pageCount(2)
.pageSize(2));5. Fetch an entity by id
GameUser user = new QueryExecutor()
.execute(Context.class, new FetchById().id(1)
.entityType(GameUser.class));#Motivation
Read, write, update data from a SQL database always spend a lot of time, and we think using Hibernate is a good choice, but we still need to design our library for easy-to-use purpose
