springmvc 时间格式处理

三种方式：

1，局部处理

标签

注解

import java.io.IOException;

import java.text.SimpleDateFormat;

import java.util.Date;

 

import org.codehaus.jackson.JsonGenerator;

import org.codehaus.jackson.JsonProcessingException;

import org.codehaus.jackson.map.JsonSerializer;

import org.codehaus.jackson.map.SerializerProvider;

 

/**

 * @description 自定义返回JSON 数据格中日期格式化处理

 * @author aokunsang

 * @date 2013-5-28

 */

public class CustomDateSerializer extends JsonSerializer<Date> {

 

@Override

public void serialize(Date value, 

JsonGenerator jsonGenerator, 

SerializerProvider provider)

throws IOException, JsonProcessingException {

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

jsonGenerator.writeString(sdf.format(value));

}

}

 

    @JsonSerialize(using = CustomDateSerializer.class)

    public Date getCreateDate() {

        return createDate;

    }

 

（2）@datetimeformate()

mapper.xml配置文件中的类型改为datedemic

2，全局处理

 

<mvc:annotation-driven>

    <mvc:message-converters register-defaults="true" >

            <bean class="org.springframework.http.converter.StringHttpMessageConverter">

                <property name="supportedMediaTypes">

                    <list>

                        <value>text/html;charset=UTF-8</value>

                        <value>text/plain;charset=UTF-8</value>

                        <value>application/json;charset=UTF-8</value>

                    </list>

                </property>

            </bean>

            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">

                <property name="objectMapper">

                    <bean class="com.esteel.until.CustomJacksonObjectMapper" />

                </property>

            </bean>

    </mvc:message-converters>

    </mvc:annotation-driven>

 

package com.esteel.until;

 

 

import java.io.IOException;

import java.text.SimpleDateFormat;

import java.util.Date;

 

import com.fasterxml.jackson.annotation.JsonInclude.Include;

import com.fasterxml.jackson.core.JsonGenerator;

import com.fasterxml.jackson.core.JsonProcessingException;

import com.fasterxml.jackson.databind.DeserializationFeature;

import com.fasterxml.jackson.databind.JsonSerializer;

import com.fasterxml.jackson.databind.ObjectMapper;

import com.fasterxml.jackson.databind.SerializationFeature;

import com.fasterxml.jackson.databind.SerializerProvider;

import com.fasterxml.jackson.databind.module.SimpleModule;

/**

 */

public class CustomJacksonObjectMapper extends ObjectMapper {

 

public CustomJacksonObjectMapper(){

super();

   this.configure(DeserializationFeature.UNWRAP_ROOT_VALUE, false);

   this.configure(SerializationFeature.WRAP_ROOT_VALUE, false);

   this.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);

   this.setSerializationInclusion(Include.ALWAYS);

   this.setDateFormat(new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"));

   //json中存在字段，但JAVA中没有的

   this.disable(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES);

   SimpleModule module = new SimpleModule();

module.addSerializer(new DealDate(Date.class));

//        module.addSerializer(new JsonDoubleSerializer(Double.class));

        this.registerModule(module);

        

   

}

class DealDate extends JsonSerializer<Date> {

    public DealDate(Class<Date> date) {

super();

}

    public Class<Date> handledType() {

return Date.class;

}

@Override

public void serialize(Date value, JsonGenerator jgen, SerializerProvider provider)

throws IOException, JsonProcessingException {

// TODO Auto-generated method stub

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");  

jgen.writeString(sdf.format(value));  

}

}

}

 

 

 

3，jsp页面处理

<td><fmt:formatDate value="${item.chkTime}" pattern="yyyy-MM-dd HH:mm:ss" /></td>

 

4,java处理

public static final String PATTERN_DATE = "yyyy-MM-dd";

SimpleDateFormat sdf = new SimpleDateFormat(PATTERN_DATE);

一般有3,4处理即可

数据库处理

数据字段类型：

CHK_TIME   ： DATE

SELECT C.* FROM TB_CUS_FIRM_CHG C WHERE 1 = 1 AND to_char(C.CHK_TIME, 'yyyy-mm-dd') >= ? AND to_char(C.CHK_TIME, 'yyyy-mm-dd') <= ? order by C.CUSTOMER_KEY asc

Parameters: 2008-06-01(String), 2016-06-20(String), 20(Integer), 0(Integer)
