The experiment was done on the project of the previous article;
Data written to page background forward dataTestController add

To restart Tomcat access:Http://localhost:8080/springmvc-2/test/toPerson4.do
Another way:
The output information is correct;/** * To define the map directly in the parameter list of the method, this map even if the map inside the Modelandview is handled uniformly by the view parser, it is not recommended to use the Modelandview interface * @param map * @ret Urn * @throws Exception*/@RequestMapping ("/toperson5.do") PublicString ToPerson5 (map<string,object>map) throws exception{ person person=NewPerson (); Person.setname ("Jerome"); Person.setage ( A); Person.setaddress ("Nanan"); SimpleDateFormat format=NewSimpleDateFormat ("YYYY-MM-DD"); Date Date= Format.parse ("2012-12-21"); Person.setbirthday (date); Map.put ("P", person); return "Jsp/index"; }To restart Tomcat access:
Recommended Use:
Http://localhost:8080/springmvc-2/test/toPerson5.do
The output is correct;/** * directly define Model,model.addattribute ("P", person) in the parameter list; * To put the parameter values in the request class, it is recommended to use * @param map * @return * @throws Exception*/@RequestMapping ("/toperson6.do") PublicString ToPerson6 (model model) throws Exception { person person=NewPerson (); Person.setname ("Jerome"); Person.setage ( A); Person.setaddress ("Nanan"); SimpleDateFormat format=NewSimpleDateFormat ("YYYY-MM-DD"); Date Date= Format.parse ("2012-12-21"); Person.setbirthday (date); //Put the parameter values in the request class.Model.addattribute ("P", person); return "Jsp/index"; }To restart Tomcat access:
Do not need page jump: Ajax Backend Method:
Http://localhost:8080/springmvc-2/test/toPerson6.do
Output the correct data;
In TestController Plus
/** * Ajax request return value type should be void, parameter list directly define HttpServletResponse, * Get Prontwriter class, finally can write results to page * Not recommended * @param name * Param response*/@RequestMapping ("/ajax.do") Public voidAjax (string name, HttpServletResponse response) {string result="Hello"+name; Try{response.getwriter (). write (result); } Catch(IOException e) {e.printstacktrace (); } }Foreground call New ajax.jsp
<input id= "MyButton" type= "button" value= "click" >
Webroot New JS folder to copy jquery in;
Introduce jquery and write JS scripts:<script type="Text/javascript">$ (function () {$ ("#myButton"). Click (function () {$.ajax ({URL:"test/ajax.do", type:"Post", DataType:"text", data:{name:"Zhangsan"}, Success:function (responsetext) {alert (responsetext); }, Error:function () {alert ("System Error"); } }); }); }); </script>Write a forward background:
@RequestMapping ("/toajax.do") public String toajax () { return"jsp/ajax"; }Restart Tomcat Access
These methods are not recommended and are recommended to use:
Http://localhost:8080/springmvc-2/test/toAjax.do
Click, pop-up Hello Zhangsan, success;/* * * define printwriter,out.wrote directly on the list of parameters ( result); * To write the results to the page, it is recommended to use * @param name * @param out */ @RequestMapping ( " /ajax1.do Span style= "color: #800000;" > " " public void ajax1 (String name, printwriter out = " hello1 " +name; out .write (Result); }Modify the Ajax.jap page, JS script, jump URL is
form:
URL: "Test/ajax1.do",
