How to use Springmvc to complete ajax function

Xiaobian to share with you how to use Springmvc to complete the Ajax function, I hope you have some gains after reading this article, let's discuss it together!

1. Add Jackson's jar package

2. Add @ResponseBody to the response method: convert java objects to json objects

3. The return value of the method can be an object collection string

$.post("ajax/Ajax1",{"name":"zhu"},function(data){ $.each(data,function(i,n){ alert(n.name); }) })

Can return strings

@RequestMapping(value="Ajax1", products = "text/html;charset=UTF-8") @ResponseBody public String ajax1(String name) { System.out.println(name); return "hello"; }

You can also return objects.

@RequestMapping("Ajax2") @ResponseBody public User ajax2(String name) { User user=new User("中","1"); return user; }

You can also return collections

@RequestMapping("Ajax3") @ResponseBody public List ajax3(String name) { User user1 =new User("中","1"); User user2 =new User("","2"); User user3 =new User("","3"); List list=new ArrayList(); list.add(user1); list.add(user2); list.add(user3); return list; }

When returning a character string, if the input Chinese characters will appear garbled, the solution is as follows

1. Change @RequestMapping

@RequestMapping(value="Ajax1",produces="text/html;charset=UTF-8")

2. Rewrite the code in the springMVC configuration file with the org.springframework.web.servlet.view.InternalResourceViewResolver class.
