Java JsonIgnore不是隐藏字段

Question

需要从Json中隐藏一个字段，但留下它，因为需要在另一个方法(get)中使用它。试图这样做，但id字段在Json中仍然可见。怎么了?

依赖性:

<properties>
<!-- Use the latest version whenever possible. -->
<jackson.version>2.4.4</jackson.version>
</properties>
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>

<scope>provided</scope>
</dependency>

</dependencies>

试着这样做:包test.model;

import java.math.BigDecimal;
import test.model.DbTest;
import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.annotation.JsonIgnoreProperties;
@JsonIgnoreProperties(value = { "id" })
public final class Home {
@JsonIgnore
private final BigDecimal id;
private final String date;
public Home( //
BigDecimal id, //
String date) {
this.id = id;
this.date = date;
}
public final BigDecimal getId() {
return id;
}
public final String getDate() {
return date;
}

public static final Home newInstance( 
DbTest test) {
return new Home( 
test.getId(), 
test.getDate());
}
}

尝试在pom.xml中使用

<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.12.4</version>
</dependency>

或从字段

中删除'final'
