When the Spring MVC return type is a string, the returned Chinese becomes "?" Processing

The Spring controller is as follows

@Controllerclass Simplecontroller {    @ResponseBody    @RequestMapping (value = "/hotel")    publicreturn "{\" status\ ": 0,\" errmsg\ ": Null,\" data\ ": {\" query\ ": \" hotel query \ ", \" num\ ": 65544,\" url\ ": \" Www.test.com\ "}}";}}     

Here using Responsebody, the return value is directly a string, no use to Jackson, if it is to return an object, using the Jackson to JSON, there is no coding problem

Then the hotel inquires a few words all become question marks

Since spring handles the result of a string type with the return value, we need to configure his encoding Stringhttpmessageconverter

    class= "Java.nio.charset.Charset"          factory-method= "forname" >        <constructor-arg value= "UTF-8"/ >    </bean>    <mvc:annotation-driven>        <mvc:message-converters>            class= " Org.springframework.http.converter.StringHttpMessageConverter ">                <constructor-arg ref=" Utf8charset "/ >            </bean>        </mvc:message-converters>    </mvc:annotation-driven>
