The Spring Expression Language, abbreviated as SpEL, is basically an expression language that is also very powerful in its workings and offers support for queries and manipulation of an object graph during runtime. The feature was released with Spring 3.0 in 2009. While the syntax of the language is pretty similar to Unified EL, it
Generally, programmers tend to declare the beans or components in a bean file of XML configuration, in order to allow the Spring container to detect and register them. However, you should know that Spring is capable of auto scanning, detecting and further, instantiating beans from the already defined project package. So, that can save you
The Object Relational Mapping (ORM) concept is much-favoured these days because of the relative advantages it offers over relational database systems. ORM makes managing databases a simpler task than relational database systems. Enterprises want to spend as less time as possible on modifying SQL queries when database types are changed. Spring JPA, which is ORM-based,
The Spring JDBC template provides a better way than the JDBC ODBC drivers for integrating Java calls or requests with popular database programs. While the objective of both, Spring JDBC and JDBC and ODBC is the same, the approaches vary greatly. In case of the latter, the developer needs to worry about a lot of
The Aspect Oriented Programming (AOP) offers a new way of looking at how software programming can be done. When compared to the Object Oriented Programming (OOP), the AOP does not represent a total or drastic departure to how programming is done. AOP just represents a new philosophy of programming and aims at improving efficiency between
Wiring of Spring beans is one of the principal factors underlying the smooth operation of Spring-based software applications. The wiring feature combines the capabilities of disparate Spring beans or objects to achieve a common goal. The beans are wired and yet not tightly coupled with one another so that such beans can be reused for
