    this.datePattern = datePattern;

//Converter<S,T>接口的类型转换方法
@Override
public Date convert(String date) {
    try {
        SimpleDateFormat dateFormat=new SimpleDateFormat(this.datePattern);
        //将日期字符串转换成date类型返回
        return dateFormat.parse(date);
    } catch (Exception e) {
        e.printStackTrace();
        System.out.println("日期转换失败");
        return null;
    }
}
@Override
public JavaType getInputType(TypeFactory arg0) {
    // TODO Auto-generated method stub
    return null;
}
@Override
public JavaType getOutputType(TypeFactory arg0) {
    // TODO Auto-generated method stub
    return null;
}

}
这复写的getOutputType和getInputType方法怎么用?我看网上的资料没有这两个方法,springmvc api里也没有介绍着两个方法.

每次启动服务都会报Error creating bean with name 'conversionService' defined in ServletContext resource [/WEB-INF/springmvc-config.xml]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Each converter object must implement one of the Converter, ConverterFactory, or GenericConverter interfaces
我不知道是不是跟我这两个方法有关系
下面是我的springmvc-config配置文件内容
