Fix Javadoc for Jackson2ObjectMapperFactoryBean [SPR-13765]

[spring-projects-issues]

umesha balasubramaniam opened SPR-13765 and commented

The javadoc for Jackson2ObjectMapperFactoryBean has an error when it describes the how to set the featuresEnabled property. The documentation incorrectly describes using the $ syntax to refer to the enum value:

<util:constant static-field="com.fasterxml.jackson.databind.SerializationFeature$WRAP_ROOT_VALUE"/>
<util:constant static-field="com.fasterxml.jackson.databind.SerializationFeature$CLOSE_CLOSEABLE"/>
<util:constant static-field="com.fasterxml.jackson.databind.MapperFeature$USE_ANNOTATIONS"/>

It should use the dot syntax:

<util:constant static-field="com.fasterxml.jackson.databind.SerializationFeature.WRAP_ROOT_VALUE"/>
<util:constant static-field="com.fasterxml.jackson.databind.SerializationFeature.CLOSE_CLOSEABLE"/>
<util:constant static-field="com.fasterxml.jackson.databind.MapperFeature.USE_ANNOTATIONS"/>

Good catch! In that context, static field references need to use Java source code syntax (dot separators), not runtime class name separators (dollars)...
