Groovy + Dropwizard和servlet 3.1.0問題

2015-05-11 73 views

我想使用基於Dropwizard框架0.8.1的groovy 2.4.1創建一個簡單的REST服務器。我使用這個概念證明Groovy腳本是：Groovy + Dropwizard和servlet 3.1.0問題

import com.codahale.metrics.annotation.Timed 
import com.google.common.base.Optional 
import io.dropwizard.Application 
import io.dropwizard.Configuration 
import io.dropwizard.setup.Bootstrap 
import io.dropwizard.setup.Environment 

import javax.ws.rs.GET 
import javax.ws.rs.Path 
import javax.ws.rs.Produces 
import javax.ws.rs.QueryParam 
import javax.ws.rs.core.MediaType 

@Grapes([ 
     @Grab(group = 'io.dropwizard', module = 'dropwizard-core', version = '0.8.1')]) 

class RESTProviderConfiguration extends Configuration { 
    String template 
} 

class RESTProviderApplication extends Application<RESTProviderConfiguration> { 

    @Override 
    String getName() { 
     'hello-world' 
    } 

    @Override 
    void initialize(Bootstrap<RESTProviderConfiguration> bootstrap) { 
    } 

    @Override 
    void run(RESTProviderConfiguration configuration, Environment environment) { 
     def resource = new HelloWorldResource(template: configuration.template); 
     environment.jersey().register(resource); 
    } 
} 


@Path('/hello-world') 
@Produces(MediaType.APPLICATION_JSON) 
class HelloWorldResource { 

    String template 

    @GET 
    @Timed 
    String sayHello(@QueryParam('name') Optional<String> name) { 
     String.format(template, name.or('John Doe')) 
    } 
} 

new RESTProviderApplication().run(args)

服務器啓動，但對資源/你好世界的請求，以下異常被拋出：

這是因爲groovy classpath有2.4 servlet版本的groovy-servlet-2.4.3.jar，而dropwizard 0.8.1有javax.servlet-api-3.1.0.jar。

你能告訴我如何更換groovy jar或首先加載所需的版本？

我剛剛遇到類似的問題。在我的情況下，問題是，有一些其他的相依性，有javax.servlet-api-2.5.0.jar所以我有javax.servlet-api

mvn dependency:tree -Dincludes=*:*servlet* 

mystuff:mystuff:jar:1.0-SNAPSHOT 

mystuff:rest-support:jar:2.0.0-RELEASE:compile 

| \- com.github.kongchen:swagger-maven-plugin:jar:2.3.4:compile 

|  \- javax.servlet:servlet-api:jar:2.5:compile 

... 

\- mystuff:myotherstuff:jar:2.2.4:compile 

    \- javax.servlet:javax.servlet-api:jar:3.1.0:compile

兩個版本，我通過手動排除從的MyStuff的Maven依賴招搖，Maven的插件固定它：休息支持

希望幫助

您必須添加javax.servlet-api與您的build.gradle 3.1.0版本的顯式依賴。

這將覆蓋由groovy提供的默認值。

dependencies { 
    compile group: 'javax.servlet', name: 'javax.servlet-api', version: '3.1.0' 
    ... 
}

有幾個選項：

  • 使用運行Groovy腳本，搶出口的servlet API到classpath中前：eval $(grape resolve -shell javax.servlet javax.servlet-api 4.0.0)
  • 或拆除或更換servlet-api-2.4.jar在$GROOVY_HOME\lib（不推薦）
