Spring Configuration (XML, Annotation & Java)

First step to use Spring in your Java application, is to create Spring configuration metadata, this metadata tells Spring what beans “Java classes” you need to be instantiated in Spring container. You have three options to write or code your configuration metadata “XML, annotation or Java configuration”

Mybatis Insert Using XML or Annotation & Return Primary ID

This is a short post on how to use MyBatis to insert an object using XML <insert> or annotation @Insert and return the value of the primary id.

  • How to get primary Id of the inserted object?

Spring @Profile

We can enable the environment-aware feature “Profile” in Spring XML configuration, also we can enable this feature using annotation @Profile in Spring @Configuration class “the Spring annotation configuration” which is equivalent to XML configuration <beans…>…..</beans>.

Spring Profile XML Configuration

If you like to load environment specific spring configuration you can do this using profile. In other words, if you want to load a set of beans that have different settings on different environment (development, testing or production) you can use profile feature instead of pointing to a different spring xml configuration at each stage.

MyBatis + Spring + Junit (The Missing Part)

We have seen in Mybatis + Spring (XML | Annotation) Mapper how to write a simple mybatis-spring app and what is actually needed to get it up and running. Here I will extend that sample code to cover more stuff that you may face in a real “coding”. We will see how to make a single select that will fetch the one and the many of a “one-to-many” relationship, who to use mybatis config file with spring (if you need it), how to test mybatis-spring code using junit and things you need to watch out!

H2 embedded database has been used to make this example easy to run. But you still can use it with other databases e.g. “MySql, Oracle,….”

Objectives:

  • How to use make a single select that will fetch all one to many records?
  • How to reference mybatis config file in spring xml config file?
  • How to test using junit?
