I develop REST-service with undertow+resteasy+ajckson, when I run this with IDEA, everything is OK, but when I create "fat-jar" with gradle or maven I get error during GET query:
org.jboss.resteasy.core.NoMessageBodyWriterFoundFailure: Could not find MessageBodyWriter for response object of type at org.jboss.resteasy.core.ServerResponseWriter.writeNomapResponse(ServerResponseWriter.java:67) at org.jboss.resteasy.core.SynchronousDispatcher.writeResponse(SynchronousDispatcher.java:448) at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:397) at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:200) at org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher.service(ServletContainerDispatcher.java:220) at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:56) at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:51) at javax.servlet.http.HttpServlet.service(HttpServlet.java:790)
I could create jar without error with gradle build
and debug my service in IDEA.
My gradle file:
apply plugin: 'application'
apply plugin: 'java'
sourceCompatibility = 1.8
targetCompatibility = 1.8
mainClassName = 'example.json.RestServer'
jar {
manifest {
attributes 'Implementation-Title': 'Rest-server',
'Implementation-Version': '0.1',
'Main-Class': 'example.json.RestServer'
}
from {
configurations.compile.collect { it.isDirectory() ? it : zipTree(it) }
}
}
repositories {
jcenter()
}
dependencies {
compile 'io.undertow:undertow-core:1.4.0.Final'
compile 'io.undertow:undertow-servlet:1.4.0.Final'
compile 'org.jboss.resteasy:jaxrs-api:3.0.12.Final'
compile 'org.jboss.resteasy:resteasy-undertow:3.0.12.Final'
compile 'org.jboss.resteasy:resteasy-jackson-provider:3.0.12.Final'
testCompile 'junit:junit:4.12'
}
My source:
@Path("calculator")
public class Calculator {
@GET
@Path("squareRoot")
@Produces(MediaType.APPLICATION_JSON)
public Response squareRoot(@QueryParam("input") double input){
Result result = new Result("Square Root");
result.setInput(input);
result.setOutput(Math.sqrt(result.getInput()));
return Response.status(200).entity(result).build();
}
