大佬教程收集整理的这篇文章主要介绍了在TomEE +上使用JAX-RS时，“无资源方法”，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

如何解决在TomEE +上使用JAX-RS时，“无资源方法”？

开发过程中遇到在TomEE +上使用JAX-RS时，“无资源方法”的问题如何解决？下面主要结合日常开发的经验，给出你关于在TomEE +上使用JAX-RS时，“无资源方法”的解决方法建议，希望对你解决在TomEE +上使用JAX-RS时，“无资源方法”有所启发或帮助；

看来您的资源方法不在public范围内。尝试这个：

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!";
  }
}

解决方法

使用库存的TomEE +，我无法获得简单的JAX-RS资源。我经常收到以下错误：

资源类：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!";
  }
}

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/XMLscheR_96_11845@a-instance"

<display-name>service</display-name>

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>

我尝试了多种排列方式，添加了beans.xml，删除了注释，更改了注释的顺序，并对Java EE类使用了不同的编译依赖项。我始终收到此错误。
