Java依赖

Question

OK I am trying to use http://jongo.org , in a project I have run mvn install and dropped the jar it returns into my project but when I try and use Jongo I get Caused by: java.lang.NoClassDefFoundError: com/fasterxml/jackson/databind/Module Does Jongo not package these directly? My question is do I need to then manually include the other jars it depends on aswell into my project root?

Answer 1

Yes, you need add this dependency manually in maven:

Jongo relies upon Jackson 2.4.1 , Bson4Jackson 2.4.0 and Mongo Java Driver 2.11+ . Its Maven dependency, an OSGI compliant jar, comes with the first two, you have to provide a dependency to the driver.

Jongo is deployed into OSS Sonatype (Maven repository hosting service for open source projects). Add the following dependency to your pom.xml

 <dependency>
     <groupId>org.jongo</groupId>
     <artifactId>jongo</artifactId>
     <version>1.2</version> </dependency>
 </dependency>
