我正在部署一个 Jersey 2.22 应用程序，我正在尝试使用 Squarespace jersey2-guice-impl 库与 Guice 4.0 顺利集成，以便我可以轻松地将 Guice 依赖项注入我的控制器。

（我对下面的小错字表示歉意，我不得不重新输入所有内容。）

但是我在启动时收到以下错误，这是由我的 WebListener 引起的：

   SEVERE: Exception starting filter jersey
   java.lang.IllegalStateException: It appears there is no ServiceLocatorGenerator installed.

我正在使用 pom.xml 中的以下依赖项：

 <dependency>
    <groupId>com.google.guava</groupId>
    <artifactId>guice</artifactId>
    <version>4.0.0</version>
 </dependency>
 <dependency>
    <groupId>com.google.inject.extensions</groupId>
    <artifactId>guice-servlet</artifactId>
    <version>4.0.0</version>
 </dependency>
 <dependency>
    <groupId>com.squarespace.jersey2-guice</groupId>
    <artifactId>jersey2-guice-impl</artifactId>
    <version>1.0.6</version>
 </dependency>
 <dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.22.2</version>
 </dependency>
 <dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-container-servlet</artifactId>
    <version>2.22.2</version>
 </dependency>
 <dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-multipart</artifactId>
    <version>2.22.2</version>
 </dependency>
 <dependency>
    <groupId>org.glassfish.jersey.ext</groupId>
    <artifactId>jersey-mvc</artifactId>
    <version>2.22.1</version>
 </dependency>

这是 WebListener：

@WebListener
public class FakeResourceManager extends GuiceServletContextListener{
      @Override protected Injector getInjector(){
           return Guice.createInjector(new ArrayList<Module>());
      }
}

这是 web.xml

<filter>
     <filter-name>GuiceFilter</filter-name>
     <filter-class>com.google.inject.servlet.GuiceFilter</filter-class>
</filter>
<filter-mapping>
     <filter-name>GuiceFilter</filter-name>
     <url-pattern>/*</url-pattern>
</filter-mapping>
<filter>
     <filter-name>jersey</filter-name>
     <filter-class>org.glassfish.jersey.servlet.ServletContainer</filter-class>
     <init-param>
        <param-name>jersey.config.server.provider.packages</param-name>
        <param-value>mypackage.rest;guice.tomcat.jersey</param-value>
     </init-param>
     <init-param>
        <param-name>jersey.config.server.provider.classnames</param-name>
        <param-value>org.glassfish.jersey.media.multipart.MultiPartFeature;org.glassfish.jersey.server.mvc.jsp.JspMvcFeature</param-value>
     </init-param>
</filter>
<filter-mapping>
  <filter-name>jersey</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

我在 Tomcat 7.0.42 中进行部署。

这看起来很简单。我认为加载时可能存在排序问题。可能在过滤器加载之前没有调用设置 ServiceLocatorGenerator。我如何强制它发生？我错过了什么？
