Springmvc using the Jackson to JSON format

If the JSON converter is not used, the following error occurs when the return method of the Ajax request declares @responsebody

"Networkerror:406 not Acceptable-http://uc.com:8081/login/check"

The/login/check request mapping method is as follows

@RequestMapping ("/login/check") @ResponseBody public map<string, string> Logincheck ( HttpServletRequest req) {    Mapnew hashmap<string, string>();    Rs.put ("Result", "success");    Rs.put ("message", "Login Successful");     return rs;}

Because the @responsebody declaration, the Jackson packet needs to be handled, the workaround is as follows

first, the introduction of the Jackson bag

Declare in Pom.xml to import the Jackson Pack

<Dependency>    <groupId>Org.codehaus.jackson</groupId>    <Artifactid>Jackson-mapper-asl</Artifactid>    <version>1.9.13</version></Dependency><Dependency>    <groupId>Org.codehaus.jackson</groupId>    <Artifactid>Jackson-core-asl</Artifactid>    <version>1.9.13</version></Dependency>

Second, the configuration Spring.xml

Add a bit of content to the spring configuration file

<!--Register the JSON converter and customize the date format conversion -<Mvc:annotation-driven>    <mvc:message-converters>        <Beanclass= "Org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">            < Propertyname= "Objectmapper">                <Beanclass= "Org.mastiff.tools.ToolJacksonDateFormat"></Bean>            </ Property>        </Bean>    </mvc:message-converters></Mvc:annotation-driven>

If you do not need additional configuration (this is the date format processing), here you actually only need one row

< Mvc:annotation-driven />

The Org.mastiff.ToolJacksonDateFormat class is used for date format conversions, converting all dates to YYYY-MM-DD HH:mm:ss format, source code
