在使用java8的過程中用到了新的日期類LocalDate允瞧、LocalDateTime類型枚抵，作為屬性不經(jīng)過任何處理轉(zhuǎn)成json的時(shí)候會(huì)變成下面的樣式乳愉。
"applicationTime": {
"month": "AUGUST",
"year": 2017,
"dayOfMonth": 2,
"dayOfWeek": "WEDNESDAY",
"dayOfYear": 214,
"monthValue": 8,
"hour": 16,
"minute": 38,
"second": 53,
"nano": 0,
"chronology": {
"id": "ISO",
"calendarType": "iso8601"
}
},
如何才能變成字符串的yyyy-MM-dd掉房，需要導(dǎo)入幾個(gè)類庫(kù)
<properties>
<jackson.version>2.8.5</jackson.version>
</properties>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>${jackson.version}</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>${jackson.version}</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>${jackson.version}</version>
</dependency>
<!-- 支持java8 localDate等新時(shí)間類型的序列化 -->
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-jsr310</artifactId>
<version>${jackson.version}</version>
</dependency>
只有jackson-datatype-jsr310是用來格式化日期用的
@JsonFormat(shape = JsonFormat.Shape.STRING, pattern = "yyyy-MM-dd HH:mm:ss")
private LocalDateTime applicationTime;
或者
@JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
private LocalDateTime applicationTime;
加上@JsonFormat注解茫陆，這樣最后當(dāng)對(duì)象轉(zhuǎn)成json的時(shí)候就變成了
"applicationTime": "2017-08-02 16:38:59",
