Question

我正在尝试在项目中使用JerseyTest框架添加ReST调用的单元测试。我复制粘贴了一个最简单的例子，但我得到了一个运行时异常：

附加代码和pom依赖项：

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.core.Application;

import static junit.framework.Assert.assertEquals;


public class SimpleTest extends JerseyTest {

    @Path("hello")
    public static class HelloResource {
        @GET
        public String getHello() {
            return "Hello World!";
        }
    }

    @Override
    protected Application configure() {
        return new ResourceConfig(HelloResource.class);
    }

    @Test
    public void test() {
        final String hello = target("hello").request().get(String.class);
        assertEquals("Hello World!", hello);
    }
}

Answer 1

如前所述，此错误是由于您的依赖项（可能是在球衣1和2之间）发生冲突。更多信息here。实际上，您使用的是版本1.18的jersey-server，以及其他版本2.6的pom.xml。

Answer 2

通过删除jersey-server和jersey-all依赖项，将jersey依赖项更新为最新版本（2.15）并添加jetty依赖项来解决。

Answer 3

我有同样的问题我正在传递这个图书馆：
org.glassfish.jersey.media:jersey-media-json-jackson:jar:2.14

我所有的版本2.6的球衣库，除了上面的版本，我的测试用例都通过了。我补充一点：

         <exclusion>
            <groupId>org.glassfish.jersey.media</groupId>
            <artifactId>jersey-media-json-jackson</artifactId>
         </exclusion>
        </exclusions>
