In this short tutorial,we’ll investigate the definition of “Plain Old Java Object”or POJO for short. We’ll look at how a POJO compares to a JavaBean, and how turning our POJOs into JavaBeans can be helpful.
添加了可用于 POJO 编码和解码的BsonExtraElements注解。BsonExtraElements可以解码将来可能接收新字段的对象,而无需开发人员显式映射这些新字段。 性能优化包括: 服务器会话池和缓冲池的无锁实现。 新的DBCursor清理实现,使用 Java 的 Cleaner API 而不是 finalization,在 Java 9 或更高版本中可用。
plain ordinary java object 简单无规则java对象,指那些没有从任何类继承、也没有实现任何接口,更没有被其它框架侵入的java对象,VO和PO应该都属于它。 POJO的意义: POJO让开发者可专注于业务逻辑和脱离框架的单元测试。除此之外, 由于POJO并不须要继承框架的类或实现其接口,开发者能够极其灵活地搭建继承结构和建造应...
Using plain old Java objects (POJO) to represent persistent data can significantly simplify database programming. A JPA implementation (sometimes referred to as a JPA provider) is needed in order to interact with a relational database such as Oracle, DB2, SQL Server or MySQL. The popular JPA...

We’ve added a new inspection to spot the most common bugs when using@ConfigurationProperties. Deprecated POJO properties are now highlighted accordingly so it’s easier to track necessary updates to your configuration. In the 2018.3.1 update, it will be possible to resolve replacement tokens to ...
Though this an integral part of the Java compiler when compiling code, there is no function in the standard Java runtime, that will convert such a String notation into an unescaped target String.Apache Commons has a StringUtils class, that can do this, but this requires a lot of overhead ...
The org.eclipse.ui.views extension point now supports an e4view element for declaring a new view for the IDE whose implementation is done in the e4 style (i.e. an annotated POJO). The new type of extension is identical to the original 'view' except for relaxing the requirement that ...
