添加关注依赖项:

<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-hk2</artifactId>
</dependency>

答案 1 :(得分:14)

我有相同的根本原因: java.lang.IllegalStateException:找不到InjectionManagerFactory

在pom.xml中进行了一些更改之后,它终于有效了。请尝试以下方法:

<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.26-b06</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-hk2</artifactId>
    <version>2.26-b06</version>
</dependency>

答案 2 :(得分:2)

同样的问题在这里:

Jersey stopped working with InjectionManagerFactory not found

解决方案:降级为平针版&#34; 2.26-b03&#34;。
