org.springframework.http.converter.json Documentation Differences

This file contains all the changes in documentation in the package org.springframework.http.converter.json as colored differences. Deletions are shown like this, and additions are shown like this.

If no deletions or additions are shown in an entry, the HTML tags will be what has changed. The new HTML tags are shown in the differences. If no documentation existed, and then some was added in a later version, this change is noted in the appropriate class pages of differences, but the change is not shown on this page. Only changes in existing text are shown here. Similarly, documentation which was inherited from another class or interface is not shown here.

Note that an HTML error in the new documentation may cause the display of other documentation changes to be presented incorrectly. For instance, failure to close a <code> tag will cause all subsequent paragraphs to be displayed differently.

Return the Jackson JavaType for the specified type and context class.

The default implementation returns ObjectMapper.constructType(java.lang.reflect.Type) or {@code ObjectMapper.getTypeFactory().constructType(type, contextClass)}, but this can be overridden in subclasses, to allow for custom generic collection handling. For instance:

 protected JavaType getJavaType(Type type) {
   if (type instanceof Class && List.class.isAssignableFrom((Class)type)) {
     return TypeFactory.collectionType(ArrayList.class, MyBean.class);
   } else {
     return super.getJavaType(type);
   }
 }
 

@param type the type to return the java type for @param contextClass a context class for the target type, for example a class in which the target type appears in a method signature, can be {@code null} signature, can be {@code null} @return the java type
