springmvc接收日期參數轉換

一、InitBinder綁定：對于目前controller有效

@InitBinder
 public void init(WebDataBinder binder) {
     binder.registerCustomEditor(Date.class, new CustomDateEditor(new SimpleDateFormat("yyyy-MM-dd"), true));
 }
           

二、注解轉換：在實體對應的屬性上加注解

@DateTimeFormat(pattern = "yyyy-MM-dd")
           

三、全局綁定

import com.guodi.common.comp.StringToDateConverter;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.convert.support.GenericConversionService;
import org.springframework.web.bind.support.ConfigurableWebBindingInitializer;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter;

import javax.annotation.PostConstruct;

@Configuration
public class WebConfigBeans {

    @Autowired
    private RequestMappingHandlerAdapter handlerAdapter;

    /**
     * 增加字元串轉日期的功能
     */
    @PostConstruct
    public void initEditableAvlidation() {
        ConfigurableWebBindingInitializer initializer = (ConfigurableWebBindingInitializer)handlerAdapter.getWebBindingInitializer();
        if(initializer.getConversionService()!=null) {
            GenericConversionService genericConversionService = (GenericConversionService)initializer.getConversionService();
            genericConversionService.addConverter(new StringToDateConverter());
        }

    }
}
           

import org.springframework.core.convert.converter.Converter;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.List;

public class StringToDateConverter implements Converter<String, Date> {
    private static final List<String> formarts = new ArrayList<String>(4);
    static{
        formarts.add("yyyy-MM");
        formarts.add("yyyy-MM-dd");

    }
