基于springboot➕springcloud传递时间参数错误

 

前台传时间参数错误

Failed to convert property value of type 'java.lang.String' to required type 'java.util.Date' for property 'createdDate';
 nested exception is org.springframework.core.convert.ConversionFailedException: 
Failed to convert from type [java.lang.String] to type [java.util.Date] for value '2017-01-05 12:45:32'; 
nested exception is java.lang.IllegalArgumentException
解决办法：

创建两个类

 a.当发送时间类型时，直接用String发送

 b.Feign客户端实现FeignFormatterRegistrar接口自定义DateFormatRegister

package com.haidai.Server.configuration;

import java.util.Date;

import org.springframework.cloud.openfeign.FeignFormatterRegistrar;
import org.springframework.core.convert.converter.Converter;
import org.springframework.format.FormatterRegistry;


/**

 * @date 2019年4月19日 上午11:43:17
 * 类说明:时间处理
 */
public class DateFormatRegister  implements FeignFormatterRegistrar{

	@Override
	public void registerFormatters(FormatterRegistry registry) {
		registry.addConverter(Date.class, String.class,  new Date2StringConverter());
	}
	
	private class Date2StringConverter implements Converter{
		@Override
		public String convert(Date source) {
			if(source!=null) {
				Long date =  source.getTime();
				return date.toString();
			}else {
				return null;
			}
			
		}

		
	}


}

provider增加相应的解析器 

package com.haidai.Server.configuration;

import java.util.Date;

import javax.annotation.PostConstruct;

import org.apache.commons.lang.StringUtils;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.convert.converter.Converter;
import org.springframework.core.convert.support.GenericConversionService;
import org.springframework.web.bind.support.ConfigurableWebBindingInitializer;
import org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter;

/**
 * @author wangdeqiu
 * @date 2019年4月19日 上午11:59:11
 * 类说明:请求前处理将字符串转成时间
 */
@Configuration
public class WebConfigBeans {

	@Autowired private RequestMappingHandlerAdapter handlerAdapter;
	
	@PostConstruct
	 public void initEditableValidation() {
		ConfigurableWebBindingInitializer initializer = (ConfigurableWebBindingInitializer) handlerAdapter.getWebBindingInitializer();
		 if (initializer.getConversionService() != null) {
			 GenericConversionService genericConversionService = (GenericConversionService) initializer.getConversionService();
			 genericConversionService.addConverter(String.class, Date.class, new String2DateConverter());
		 }
	}
	
	private class String2DateConverter implements Converter{

		@Override
		public Date convert(String source) {
			if(StringUtils.isNotEmpty(source)) {
				return new Date(Long.valueOf(source));
			}else {
				return null;
			}
			
		}

	}

	
}

在启动类中处理时间为null的情况

//接收时间类型时传值不能为空的问题解决。
	@InitBinder
    public void initBinder(HttpServletRequest request
                           , ServletRequestDataBinder binder) throws Exception {
        binder.registerCustomEditor(String.class, new StringTrimmerEditor(true));
    }

在controller请求中增加参数，
