import org.springframework.core.convert.converter.Converter;
import org.springframework.stereotype.Component;

import java.util.Date;

@Component
public class GlobalFormStrToDateConvert implements Converter<String, Date> {

    @Override
    public Date convert(String dateStr) {
        try {
            return DateUtil.formatDateStrToDateAllFormat(dateStr);
        } catch (Exception e) {
            return null;
        }
    }
}

二. 全局@ControllerAdvice + @InitBinder注解的方式

@ControllerAdvice注解會(huì)攔截所有controller請(qǐng)求，配合@InitBinder注解，在參數(shù)封裝到實(shí)體類之前將String日期轉(zhuǎn)換為Date日期。

import org.springframework.web.bind.WebDataBinder;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.InitBinder;

import java.beans.PropertyEditorSupport;
import java.util.Date;

@ControllerAdvice
public class GlobalFormStrToDateConvert {

    @InitBinder
    protected void dateStrToDate(WebDataBinder binder) {

        binder.registerCustomEditor(Date.class, new PropertyEditorSupport() {

            @Override
            public void setAsText(String dateStr) throws IllegalArgumentException {
                Date date = DateUtil.formatDateStrToDateAllFormat(dateStr);
                setValue(date);
            }
        });
    }
}

三. RequestMappingHandlerAdapter的方式

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.bind.support.WebBindingInitializer;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter;

import java.beans.PropertyEditorSupport;
import java.util.Date;

@Configuration
public class GlobalFormStrToDateConvert {

    @Bean
    public RequestMappingHandlerAdapter webBindingInitializer(RequestMappingHandlerAdapter requestMappingHandlerAdapter) {
		
		// 通過(guò)lombda表達(dá)式創(chuàng)建WebBindingInitializer對(duì)象
        WebBindingInitializer webBindingInitializer = binder -> binder.registerCustomEditor(Date.class, new PropertyEditorSupport() {
            @Override
            public void setAsText(String dateStr) {
                Date date = DateUtil.formatDateStrToDateAllFormat(dateStr);
                setValue(date);
            }
        });
        requestMappingHandlerAdapter.setWebBindingInitializer(webBindingInitializer);
        return requestMappingHandlerAdapter;
    }
}

四. 效果

?前臺(tái)JS

const jsonData = {
	// ??待處理的日期字符串?dāng)?shù)據(jù)
    birthday: '20210105',
    nameAA: 'jiafeitian',
    hobby: '吃飯'
};

$.ajax({
    url: '后臺(tái)url',
    type: 'POST',
    // 對(duì)象轉(zhuǎn)換為json字符串
    data: jsonData,
    // 指定為表單提交
    contentType: "application/x-www-form-urlencoded",
    success: function (data, status, xhr) {
        console.log(data);
    }
});

?后臺(tái)Form

import lombok.Data;
import java.util.Date;

@Data
public class Test15Form {

    private String name;

    private String hobby;

    private String address;
	
	// 用來(lái)接收的Date類型的數(shù)據(jù)
    private Date birthday;
}

??可以看到前臺(tái)提交的日期字符串被轉(zhuǎn)換為Date格式了
