This library is no longer actively maintained. If you'd like to reuse the implementation, please fork this repository or ask me to add you to the collaborators (I can still work on releasing libs onto sonatype and Maven central).
"ScalikeSolr" is a simple Solr client library for Scala. And it also works fine with Java.
libraryDependencies ++= Seq(
"com.github.seratch" %% "scalikesolr" % "4.10.0"
)Available on maven central repository.
<dependency>
<groupId>com.github.seratch</groupId>
<artifactId>scalikesolr_2.11</artifactId>
<version>4.9.0</version>
</dependency>Using Core Query Paramters and Common Query Parameters:
import com.github.seratch.scalikesolr._
val client = Solr.httpServer(new URL("http://localhost:8983/solr")).newClient
val request = new QueryRequest(query = Query("author:Rick"))
val response = client.doQuery(request)
println(response.responseHeader)
println(response.response)
response.response.documents foreach {
case doc => {
println(doc.get("id").toString()) // "978-1423103349"
println(doc.get("cat").toListOrElse(Nil).toString) // List(book, hardcover)
println(doc.get("title").toString()) // "The Sea of Monsters"
println(doc.get("pages_i").toIntOrElse(0).toString) // 304
println(doc.get("price").toDoubleOrElse(0.0).toString) // 6.49
}
}It requires no-argument constructor and setters for fields. It is also possible to specify user-defined type that has one argument(String) constructor.
case class PageI(val value: String = "")
case class Book(
var id: String = "",
var cat: List[String] = Nil,
var price: Double = 0.0,
var pageI: PageI = PageI(),
var sequenceI: Int = 0 ) {
def this() = {
this ("", Nil, 0.0, PageI(), 0)
}
}
val book = doc.bind(classOf[Book])
println(book.id) // "978-1423103349"
println(book.cat.size) // 2
println(book.price) // 6.49
println(book.pageI.value) // 304
println(book.sequenceI) // 2See the documentation for more detail.
