My Spring Data JPA tutorial has taught us that we can create database queries and persist entities in the database by using special repository interfaces. This raises an interesting question: How can we write integration tests for our Spring Data JPA repositories because they are just interfaces? This blog post answers to that question. During […] Read More

If we are using Spring Data Solr in a real life software project, the odds are that sooner or later we will face a requirement which states that our application must be able to communicate with both a local Solr server and a SolrCloud. At the moment, fulfilling this requirement means that we have to […] Read More

Today's war story talks about the like expression handling of Spring Data JPA. Although I have written earlier about a better solution for implementing text based search functions, using an external search server like Solr is not a viable option if the implemented search function is rather simple. Let's consider the following example. Using the […] Read More

I am a bit ashamed to admit this but until yesterday, I had no idea that I can add validation to a REST API by using the @Valid and the @RequestBody annotations. This was not working in Spring MVC 3.0 and for some reason I had not noticed that the support for this was added […] Read More

The current implementation of our search function shows all search results in a single page. This is not a viable solution for most real life applications because the […] Read More

The previous parts of my Spring MVC Test tutorial have described how we can write integration tests for a REST API. Although the techniques described in those blog posts are useful, the problem is that our assertions were not very elegant. Our assertions were basically ensuring that the body of the HTTP response contained the […] Read More
