Jackson ObjectMapper 将本地日期序列化为长字符串

Question

I am trying to serialize my myBeanObject using jackson Objectmapper. This is what I have:

Objectmapper m= new Objectmapper()
m.setdateFormat(new SimpledateFormat("yyyy-MM-dd")); 
String json = m.writeValueAsString(myBeanObject);

Problem is a LocalDate variable in my bean is getting serialised into a long String, something like {"year":1970,"month":"JANUARY"...}

I want the LocalDate to become simple like "1970-01-01"

Can someone please help?

Try to add this dependency:

<dependency>
    <groupId>com.fasterxml.jackson.datatype</groupId>
    <artifactId>jackson-datatype-jsr310</artifactId>
    <version>2.8.6</version>
</dependency>

Then setup your ObjectMapper as follows:

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
mapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
