环境:

　　- spring 3.2.18.RELEASE

First - pom文件添加依赖

复制代码

<!--全局配置日期字符串处理-->
<dependency>
   <groupId>com.fasterxml.jackson.core</groupId>
   <artifactId>jackson-databind</artifactId>
   <version>2.10.5</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.datatype/jackson-datatype-jsr310 -->
<dependency>
   <groupId>com.fasterxml.jackson.datatype</groupId>
   <artifactId>jackson-datatype-jsr310</artifactId>
   <version>2.10.5</version>
</dependency>

复制代码

<!--Hutool工具包-->
<dependency>
    <groupId>cn.hutool</groupId>
    <artifactId>hutool-all</artifactId>
    <version>5.4.3</version>
</dependency>

Second - 写配置类

复制代码

 1 import com.fasterxml.jackson.annotation.JsonInclude;
 2 import com.fasterxml.jackson.databind.ObjectMapper;
 3 
 4 import java.text.SimpleDateFormat;
 5 import java.time.ZoneId;
 6 import java.util.Locale;
 7 import java.util.TimeZone;
 8 
 9 /**
10  * jackson转json时格式化日期显示，全局设置
11  * 在spring-mvc.xml中配置
12  */
13 public class CustomObjectMapper extends ObjectMapper {
14     public CustomObjectMapper() {
15         SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
16         this.setDateFormat(sdf);
17         this.setTimeZone(TimeZone.getTimeZone(ZoneId.systemDefault()));
18         this.registerModule(new JavaTimeModule());
19         this.setLocale(Locale.getDefault());
20         this.setSerializationInclusion(JsonInclude.Include.NON_EMPTY);
21     }
22 }

复制代码

Third - 书写日期转换类

复制代码

import cn.hutool.core.date.DatePattern;
import com.fasterxml.jackson.databind.cfg.PackageVersion;
import com.fasterxml.jackson.databind.module.SimpleModule;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateDeserializer;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalDateTimeDeserializer;
import com.fasterxml.jackson.datatype.jsr310.deser.LocalTimeDeserializer;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateSerializer;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalDateTimeSerializer;
import com.fasterxml.jackson.datatype.jsr310.ser.LocalTimeSerializer;

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;
import java.time.format.DateTimeFormatter;

public class JavaTimeModule extends SimpleModule {
    public JavaTimeModule() {
        super(PackageVersion.VERSION);
        this.addSerializer(LocalDateTime.class, new LocalDateTimeSerializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATETIME_PATTERN)));
        this.addSerializer(LocalDate.class, new LocalDateSerializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATE_PATTERN)));
        this.addSerializer(LocalTime.class, new LocalTimeSerializer(DateTimeFormatter.ofPattern(DatePattern.NORM_TIME_PATTERN)));
        this.addDeserializer(LocalDateTime.class, new LocalDateTimeDeserializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATETIME_PATTERN)));
        this.addDeserializer(LocalDate.class, new LocalDateDeserializer(DateTimeFormatter.ofPattern(DatePattern.NORM_DATE_PATTERN)));
        this.addDeserializer(LocalTime.class, new LocalTimeDeserializer(DateTimeFormatter.ofPattern(DatePattern.NORM_TIME_PATTERN)));
    }
}

Fifth-注入mvc容器

`ps: 注意路径替换`

复制代码

 1 <!-- 注册json转换器，并自定义日期格式转换-->
 2     <mvc:annotation-driven>
 3         <mvc:message-converters>
 4             <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
 5                 <property name="objectMapper">
 6                     <bean class="com.framework.mvc.CustomObjectMapper"/>
 7                 </property>
 8             </bean>
 9         </mvc:message-converters>
10     </mvc:annotation-driven>
