Spring3.0+jsonview/jackson

First, web.xml configuration:

<! DOCTYPE Web-app Public "-//sun Microsystems, INC.//DTD Web Application 2.3//en" "Http://java.sun.com/dtd/web-app_2_3.dt D "> <web-app> <display-name>archetype Created Web application</display-name> <context -param> <param-name>contextConfigLocation</param-name> <param-value> Classpath*:sprin G/*.xml </param-value> </context-param> <!--Filter encoding--> <filter> <fil Ter-name>characterencodingfilter</filter-name> <filter-class> Org.springframework.web.filter.characterencodingfilter</filter-class> <init-param> <param-name

 </servlet-mapping> </web-app>

Second, spring-servlet.xml configuration

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

Third, Pom.xml

Four, controller code

@Controller
@RequestMapping ("/xxx") public
class Aaaaacontroller {
	
	private static Logger Logger = Loggerfactory.getlogger (aaaaacontroller.class);

	@Resource
	private ffffbiz xxxxeeee;
	
    @RequestMapping ("/test_json")
    @ResponseBody public  
    map<string,object>  testJson3 (Param p) {
    	System.out.println ("Enter ...");
    	System.out.println ("value....==========" +p.getid ());
    	 map<string,object> map = new hashmap<string,object> ();  
         Map.put ("code", true);  
    	return map;
    }
