web services - WebService Project Java on Gradle Project -


i'm developing webservice in java using netbeans , using gradle depency mannagement.

i found this article developing web projects gradle. uses gretty plugin. followed instructions ( changed servlet container jetty tomcat ) , develop/deploy web project , open "home page" servlet.

the problem webservice classes not working properly. requests made browser returns 404 error code. testing, made new webproject using netbeans time without gradle , works charm.

here follows code:

build.gradle

buildscript {     repositories {         jcenter()     }     dependencies {         classpath 'org.akhikhl.gretty:gretty:+'     } }  apply plugin: 'java' apply plugin: 'war' apply plugin: 'org.akhikhl.gretty'  gretty {     port = 8088     contextpath = '/sisvendas'     servletcontainer = 'tomcat8' } repositories {     mavencentral() }  dependencies {     testcompile group: 'junit', name: 'junit', version: '4.10'     compile group: 'javax.servlet', name: 'javax.servlet-api', version: '3.1.0'     compile group: 'javax.ws.rs', name: 'javax.ws.rs-api', version: '2.0.1'  }

the resource:

@path("produtos") public class produtosresource {      @context     private uriinfo context;      public produtosresource() {     }      @get     @produces("application/json")     public string getjson() {         // testing...         return "{\"produtos\":\"arroz\"}";     }      @put     @consumes("application/json")     public void putjson(string content) {     } }

application config class:

public class apllicationconfig extends application{  @override public set<class<?>> getclasses() {      set<class<?>> resourcesset = new java.util.hashset<>();     adicionarclassesrecursos( resourcesset );     return resourcesset;  }  private void adicionarclassesrecursos( set<class<?>> resources ) {     resources.add( com.gear.dev.webprojectgradle.resources.produtosresource.class ); }  }

and url get: http://localhost:8088/sisvendas/produtos

as said before, following request works: http://localhost:8088/sisvendas/ ( there index.html file useless )

what i'm doing wrong?

jax-rs specification. needs implemented have use. dependency have javax.ws.rs-api, specification jar. there no implementation, meaning there no engine run application. implementation provide engine run jax-rs application.

that being said, jax-rs specification part of java ee specification, if running in java ee compliant application server, wildfly or glassfish, application server have jax-rs implementation internally, need @ application project level, specification jar compile source code, , application server have engine run application @ runtime.

but in case, tomcat is not java ee compliant server. servlet container, implements servlet specification. still need jax-rs implementation if want use jax-rs tomcat. jersey 1 such implementation. use jersey implementation, need following dependency

compile 'org.glassfish.jersey.containers:jersey-container-servlet:2.23' compile 'org.glassfish.jersey.media:jersey-media-json-jackson:2.23'

the latter dependency add json/pojo support. thing missing in code @applicationpath annotation on application class

@applicationpath("/") public class apllicationconfig extends application {

the @applicationpath annotation sets servlet mapping jersey application. if changed /api, uri access is

http://localhost:8080/sisvendas/api/produtos

node.js - How do I prevent MongoDB replica set from querying the primary? -

read-operations-only: is there way have mongodb replica set, make mongodb instance on box connected to, mongodb gets queried? i have 3 ec2 instances behind aws load balancer. on each ec2 instance runs mongodb, part of replica set. i have express endpoints on nodejs , connect replica set follows mongodb.mongoclient.connect('mongodb://1.1.1.1,2.2.2.2,3.3.3.3.', function (err, db) { if (err) { complete('{}'); } else { i distribute load of queries evenly across 3 instances of mongodb replica set instead of default having queries routed ec2 instance primary mongodb defined, because destroys point of load balancer (which balance load of queries across 3 instances evenly). my understanding when connecting mongodb replica set, primary instance selected unless primary instance down, , therefore purpose of every secondary instance serve backup. in example people call hot,cold,cold. because there 2...
