Practice SPRINGMVC Converter is a problem: form submission does not go through a custom converter (fix: Table is submitted by post only)

Custom Converter Code

 Packagecn.liangqinghai.test;ImportOrg.springframework.core.convert.converter.Converter;Importcn.liangqinghai.pojo.Student; Public classMyconverterImplementsConverter<string, student>{@Override PublicStudent Convert (String source) {System.out.println ("What the Custom converter accepts"); String[] Val=NULL; if(Source! =NULL&& "". Equals (source)) {Val= Source.split ("-"); String Sid= Val[0]; String sname= Val[1]; String Password= Val[2]; Student Student=NewStudent (Integer.parseint (SID), sname, password); System.out.println ("Converted content:" +student); returnstudent; }                return NULL; }}

Controller code

/** *************************** Test Automatic type conversion ************************************************* */     @RequestMapping ("/converter")    public String testconverter (@ModelAttribute (" Student ") Student Student) {                studentdao.add (Student);                 return "Redirect:/curd/listall";            }

Spring.xml configuration file

!----><Mvc:annotation-drivenConversion-service= "Conversionservice"></Mvc:annotation-driven>        <!--Configuring Custom Converters -    <BeanID= "Conversionservice"class= "Org.springframework.context.support.ConversionServiceFactoryBean">                < Propertyname= "Converters">            <List>                <Beanclass= "Cn.liangqinghai.test.MyConverter"></Bean>            </List>        </ Property>            </Bean>


<H1>Test your custom Converter</H1>    <formAction= "${pagecontext.request.contextpath}/curd/converter"Method= "POST">        <inputtype= "text"name= "Student">        <inputtype= "Submit">    </form>

Form submission must be post
