Recently integrated with spring4.x jackson------>java.lang.classnotfoundexception:

Recently integrated with spring4.x Jackson, the results have been inexplicably error, the results of online collection is in Maven or gradle environment to configure the dependency conditions, but the eclipseide environment of the jar package should be automatically dependent on the innuendo. The result has not been found to solve the answer.

Later, it is really a way of wood, suspected version of the problem, the result is a version of the problem caused. spring4.x must use at least Jackson2.6 to match.

The error is as follows:

 <span style= "FONT-SIZE:18PX;" >java.lang.classnotfoundexception: Com.fasterxml.jackson.core.util.DefaultIndenter at Org.apache.catalina.loader.WebappClassLoaderBase.loadClass ( Webappclassloaderbase.java:  1308) at Org.apache.catalina.loader.WebappClassLoaderBase.loadClass (Webappclassloaderbase.java:  1142) </span

Replacing Jackson's bag with more than 2.6 will solve it. Three core packages, available online.
