springmvc的ajax

Ajax controller type when requesting assignment will be the same, but the return value, because it will take the view resolver, it will be resolved in the form of address, but does not return data, the need to add annotation on the method, the return type resolution type into json

A return to the basic type

 

 @ResponseBody return type parsed form into json

 

Second, the return object

You need to import the jar package

 

 Annotate @ResponseBody on the method need to return an object

 

 Third, the return type is consistent with the object list

 

 

Note: ajax garbled

Cause when parsing String, default is ISO-8859-1

 

 Two solutions

First, annotation

Adding annotations @RequestMapping attribute produces = "text / html; charset = UTF-8"

 

 

Second, be configured springmvc

 

 

Because the assignment is the constructor, so to configure file

 

 index is the index of the constructor, starting from 0.
