在TomEE +上使用JAX-RS時「無資源方法」

Question

使用庫存TomEE +，我無法獲得簡單的JAX-RS資源。我不斷地得到一個錯誤：

資源類： 包com.tensorwrench.test;

import javax.ws.rs.*; 
import javax.ws.rs.core.Response; 
@Path("/test") 
public class BaseResource { 
    @GET @Produces("text/plain") @Path("test") Response helloWorld() { 
    return Response.ok("Hello world","plain/text").build(); 
    } 
    @GET @Produces("text/plain") String helloWorld2() { 
    return "Hello world without path!"; 
    } 
} 

的web.xml：

<?xml version="1.0" encoding="UTF-8"?> 
<web-app id="api" version="3.0" 
    xmlns="http://java.sun.com/xml/ns/j2ee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_3_0.xsd"> 
<display-name>Service</display-name> 

的build.gradle：

apply plugin: 'java' 
apply plugin: 'war' 

repositories { mavenCentral() } 

dependencies { 
    providedCompile 'org.apache.openejb:javaee-api:6.0-4' 
} 

version = '1.0' 
jar { 
     manifest { 
       attributes 'Title': 'Services', 
            'Version': version 
     } 
} 

</web-app> 

我已經嘗試了數排列，添加beans.xml文件，刪除，更改註釋的順序，爲Java EE類使用不同的編譯依賴關係。我一直得到這個錯誤。

它看起來像你的資源方法不是public的範圍。試試這個：

import javax.ws.rs.*; 
import javax.ws.rs.core.Response; 
@Path("/test") 
public class BaseResource { 
    @GET @Produces("text/plain") @Path("test") public Response helloWorld() { 
    return Response.ok("Hello world","plain/text").build(); 
    } 
    @GET @Produces("text/plain") public String helloWorld2() { 
    return "Hello world without path!"; 
    } 
}
