Method Detail

setObjectMapper

public void setObjectMapper(com.fasterxml.jackson.databind.ObjectMapper objectMapper)

Sets the ObjectMapper for this view. If not set, a default ObjectMapper is used.

Setting a custom-configured ObjectMapper is one way to take further control of the JSON serialization process. For example, an extended SerializerFactory can be configured that provides custom serializers for specific types. The other option for refining the serialization process is to use Jackson's provided annotations on the types to be serialized, in which case a custom-configured ObjectMapper is unnecessary.

setEncoding

public void setEncoding(com.fasterxml.jackson.core.JsonEncoding encoding)

Sets the JsonEncoding for this converter. By default, UTF-8 is used.

setRenderedAttributes

public void setRenderedAttributes(java.util.Set<java.lang.String> renderedAttributes)

Sets the attributes in the model that should be rendered by this view. When set, all other model attributes will be ignored.

prepareResponse

protected void prepareResponse(javax.servlet.http.HttpServletRequest request,
                               javax.servlet.http.HttpServletResponse response)

Overrides:

prepareResponse in class org.springframework.web.servlet.view.AbstractView

renderMergedOutputModel

protected void renderMergedOutputModel(java.util.Map<java.lang.String,java.lang.Object> model,
                                       javax.servlet.http.HttpServletRequest request,
                                       javax.servlet.http.HttpServletResponse response)
                                throws java.lang.Exception

Specified by:

renderMergedOutputModel in class org.springframework.web.servlet.view.AbstractView

Throws:

java.lang.Exception

filterModel

protected java.lang.Object filterModel(java.util.Map<java.lang.String,java.lang.Object> model)

Filters out undesired attributes from the given model. The return value can be either another Map, or a single value object.

Default implementation removes BindingResult instances and entries not included in the renderedAttributes property.

Parameters:

model - the model, as passed on to renderMergedOutputModel(java.util.Map<java.lang.String, java.lang.Object>, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse)

Returns:

the object to be rendered
