Spring 2.5 With JSON View

Steps to configure JSON View as a view resolver.

1)      Create views.xml & put it into WEB-INF. Once you create a bean for jsonView it will automatically search for the views.xml file in WEB-INF folder.

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN"

              "http://www.springframework.org/dtd/spring-beans-2.0.dtd">

<beans>

      <bean name="jsonView" class="org.springframework.web.servlet.view.json.JsonView">

            <property name="jsonWriter">

                  <ref bean="jsonWriter" />

            </property>

      </bean>

      <bean name="jsonWriter"

            class="org.springframework.web.servlet.view.json.writer.sojo.SojoJsonStringWriter">

            <property name="keepValueTypesMode">

                  <value>ALL</value>

            </property>

      </bean>

</beans>

2)      Creating bean’s for view resolver such as the application should support more than one view.

      <bean id="resourceViewResolver"

            class="org.springframework.web.servlet.view.ResourceBundleViewResolver">

            <property name="basename" value="views" />

            <property name="order" value="2" />

      </bean>

     

      <bean id="xmlViewResolver"

            class="org.springframework.web.servlet.view.XmlViewResolver">

            <property name="order" value="1" />

      </bean>

Generally we use to write view resolver bean configuration in servler.xml.

Observe the order attribute for above bean. We have configure to view resolver here.

3)      Returning jsonView as a view from Spring Controller.

JSONObject jsonObject = new JSONObject();

jsonObject.put("success", true);

return new ModelAndView("jsonView", jsonObject);

4)      You can check JSON response in firebug.

5)      Required libraries :-

http://sourceforge.net/projects/json-lib/files/

                Jquery, extjs, YUI, etc library supports for the JSON.

                e.g. We can bind JSON data coming from server directly to the table provided by javascript lib.
