      public EmptyView()

      Constructor for EmptyView.

  • Method Details

    • 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.

      Parameters:
      objectMapper - a ObjectMapper object

    • setEncoding

      public void setEncoding(com.fasterxml.jackson.core.JsonEncoding encoding)
      Sets the JsonEncoding for this converter. By default, UTF-8 is used.
      Parameters:
      encoding - a JsonEncoding object

    • setRenderedAttributes

      public void setRenderedAttributes(Set<String> renderedAttributes)
      Sets the attributes in the model that should be rendered by this view. When set, all other model attributes will be ignored.
      Parameters:
      renderedAttributes - a Set object

    • 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(Map<String,Object> model, javax.servlet.http.HttpServletRequest request, javax.servlet.http.HttpServletResponse response) throws Exception
      Specified by:
      renderMergedOutputModel in class org.springframework.web.servlet.view.AbstractView
      Throws:
      Exception

    • filterModel

      protected Object filterModel(Map<String,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
