First prepare juqury-ui, Ztree js files and CSS files, the next step Xiang see this article hope to help you

The first step: First prepare Juqury-ui, Ztree js files and CSS files
Step two: Write in example.jsp file code

Copy Code code as follows:


.. Introduction of jQueryUI, Ztree js and css file


<body>


<button value= "Click on the Dialog dialog box of the pop-up tree" onclick = "gettree ()"/>


<div id= "Ztree" class= ztree "/>"


</body>


<script type= "Text/javascript" >


function Gettree () {


var url = "<c:url value= ' xx.html '/>";


var setting={


};


var znodes =[];


var option={


width:200,


hight:300


};


$.ajax ({


Url:url,


success:function (data) {


$.each (data,funtion (n,d) {


Znode.push ({


Id:d.id,


Name:d.name,


Pid:d.pid


})


});


$.fn.init.ztree (' #ztree '), Setting,znode);


$ (' #ztree '). dialog (option);


}


})


}


</script>


Step three: Provide data backstage

Copy Code code as follows:


@RequestMapping ("/zone_ajaxtree")


@ResponseBody


public list<zonebody> Zone_ajaxtree () {


list<zonebody> zones = Zonebodyservice.getzone_ajax ();


return zones;


}


Because to use the @responsebody, to introduce Jackson-core-asl-1.8.7.jar and Jackson-mapper-asl-1.8.7.jar, there is code in the Mvc.xml file:

Copy Code code as follows:


<bean
class= "Org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" >
<property name= "Webbindinginitializer" >
<bean class= "Com.building.controller.BindingInitializer" />//here for user-defined
</property>
<property name= "Messageconverters" >
<ref bean= " Jsonhttpmessageconverter "/>//here provides JSON support for @responsebody
</property>
</bean>
<bean id= "Jsonhttpmessageconverter"
class= " Org.springframework.http.converter.json.MappingJacksonHttpMessageConverter "/>
