Spring MVC框架下提交Date数据无法在controller直接接收

主要有两步，controller中添加initBinder方法，再创建一个时间类型数据转换类就OK了。

 

1、在Controller中创建方法：

// 相关包
import java.text.DateFormat;
import org.springframework.beans.propertyeditors.CustomDateEditor;
import org.springframework.web.bind.ServletRequestDataBinder;

// 方法
@InitBinder
protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) throws Exception {
    DateFormat df = new MyDateFormat("yyyy-MM-dd HH:mm:ss");
    CustomDateEditor editor = new CustomDateEditor(df, false);
    binder.registerCustomEditor(Date.class, editor);
}

例如：

@Controller
public class MyController {

    @InitBinder
    protected void initBinder(HttpServletRequest request, ServletRequestDataBinder binder) throws Exception {
        DateFormat df = new MyDateFormat("yyyy-MM-dd HH:mm:ss");
        CustomDateEditor editor = new CustomDateEditor(df, false);
        binder.registerCustomEditor(Date.class, editor);
    }
    // 省略
}    

 

 

2、创建日期类：MyDateFormat

package com.common.util;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class MyDateFormat extends SimpleDateFormat {
    
    private static final long serialVersionUID = 2371168145105228746L;
    
    private String[] patterns = new String[] { "yyyyMMdd", "yyyy-MM-dd HH:mm", "HH:mm", "yyyy-MM-dd" };

    public Date parse(String source) throws ParseException {
        try {
            if (source == null)
                source = "";
            if (toPattern().length() == source.length())
                return super.parse(source);
            for (int i = 0; i < patterns.length; i++) {
                if (patterns[i].length() == source.length()) {
                    applyPattern(patterns[i]);
                    return super.parse(source);
                }
            }
            return null;
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }

    public MyDateFormat() {
        super();
    }

    public MyDateFormat(String pattern) {
        super(pattern);
    }

}
