java – 在TomEE上使用JAX-RS时的“无资源方法”

使用库存TomEE,我无法获得简单的JAX-RS资源.我不断得到一个错误：

资源类：
package 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!";
  }
}

web.xml中：

<?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>

我尝试了一些排列,添加beans.xml,删除,更改注释的顺序,使用不同的Java EE类编译依赖项.我一直都会遇到这个错误.

解决方法

看起来您的资源方法在范围上不公开.试试这个：

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!";
  }
}
