Beschreibung

Using Jersey for the REST layer in a project, I've got a dependency conflict when using Spring Cloud as follow:

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-parent</artifactId>
                <version>Brixton.M4</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-zuul</artifactId>
      </dependency>
      <dependency>
          <groupId>org.springframework.cloud</groupId>
          <artifactId>spring-cloud-security</artifactId>
          <scope>runtime</scope>
      </dependency>

The Spring Boot Jersey dependency org.springframework.boot:spring-boot-starter-jersey:jar:1.3.2.RELEASE is used.

The error is

java.lang.NoSuchMethodError: javax.ws.rs.core.Application.getProperties()Ljava/util/Map;
    at org.glassfish.jersey.server.ApplicationHandler.<init>(ApplicationHandler.java:331) ~[jersey-server-2.22.1.jar:na]
    at org.glassfish.jersey.servlet.WebComponent.<init>(WebComponent.java:390) ~[jersey-container-servlet-core-2.22.1.jar:na]
    at org.glassfish.jersey.servlet.ServletContainer.init(ServletContainer.java:172) ~[jersey-container-servlet-core-2.22.1.jar:na]
    at org.glassfish.jersey.servlet.ServletContainer.init(ServletContainer.java:364) ~[jersey-container-servlet-core-2.22.1.jar:na]
    at javax.servlet.GenericServlet.init(GenericServlet.java:158) ~[tomcat-embed-core-8.0.30.jar:8.0.30]

and it comes from the fact that both

  • javax.ws.rs:javax.ws.rs-api:jar:2.0.1:compile
  • javax.ws.rs:jsr311-api:jar:1.1.1:runtime are present in the classpath.

spring-cloud-starter-zuul includes jsr311-api.jar from its ribbon-httpclient dependency

+- com.netflix.ribbon:ribbon-httpclient:jar:2.1.0:compile
    [INFO] |  |  |  +- com.sun.jersey:jersey-client:jar:1.19:runtime
    [INFO] |  |  |  |  \- com.sun.jersey:jersey-core:jar:1.19:runtime
    [INFO] |  |  |  |     \- javax.ws.rs:jsr311-api:jar:1.1.1:runtime
    [INFO] |  |  |  \- com.sun.jersey.contribs:jersey-apache-client4:jar:1.19:runtime

I solved it by excluding jersey-client like this

<dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-parent</artifactId>
                <version>Brixton.M4</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependency>
          <groupId>org.springframework.cloud</groupId>
          <artifactId>spring-cloud-starter-zuul</artifactId>
          <exclusions>
                <exclusion>
                    <groupId>com.sun.jersey</groupId>
                    <artifactId>jersey-client</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>com.sun.jersey.contribs</groupId>
                    <artifactId>jersey-apache-client4</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-security</artifactId>
            <scope>runtime</scope>
        </dependency>

It works when testing Zuul manually but I'm not sure it would under all conditions.

It's heavy handed but I figure I already have a much newer jersey client org.glassfish.jersey.core:jersey-client:jar:2.22.1:compile included with Spring Boot Jersey.

Why would ribbon use older Jersey client dependency? Is there any reason it wouldn't work with the newest org.glassfish.jersey.core:jersey-client:jar:2.22.1 ??
