2.WritegroovyclientinHttpSolrServerGroovyTest.groovy

packagecom.sillycat.easyhunter.plugin.solr

classHttpSolrServerGroovyTest{

staticmain(args){

Stringurl="http://localhost:8983/solr"

HttpSolrServerserver=newHttpSolrServer(url);

Stringquery="name:DDR";

SolrParamsparams=newSolrQuery(query);

try{

QueryResponseresponse=server.query(params);

SolrDocumentListlist=response.getResults();

for(inti=0;i<list.size();i++){

println(list.get(i));

}

}catch(SolrServerExceptione){

e.printStackTrace();

}

println'done'

}

}

errormessage:

solution:

No,Ididnotsolvethisproblem.

Atlast,wecanrunthefunctionas'GroovyScript'and'JavaApplication'.
