How do I know what implementation of jaxrs I am using?
问题
我有一个使用Java 1.7的应用程序。它具有一些RESTful API。
我想要向一个字段添加@JsonIgnore注解，以便在API中不返回它。
例如：
Member.java
import com.fasterxml.jackson.annotation.JsonIgnore;
private java.lang.String username;
@JsonIgnore
private java.lang.String password;
但是这并没有忽略密码。
"member": {
"password": "**************",
"username": "richard"
}
我认为@JsonIgnore不起作用的原因是因为我使用了com.fasterxml.jackson.annotation.JsonIgnore。我应该使用来自不同库的不同注解吗？即，我的JAX-RS实现可能不是com.fasterxml.jackson吗？我该如何判断？
IntelliJ的类路径包括：
（我已尝试使用net.minidev.json.annotate.JsonIgnore但没有成功）
更多信息：
pom.xml
<dependency>
<groupId>net.minidev</groupId>
<artifactId>json-smart</artifactId>
<version>2.3</version>
</dependency>
和
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.11.2</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.11.2</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.11.2</version>
</dependency>
这是问题吗？有两个不同版本！我不确定2.0.5版本是从哪里来的，因为它没有在pom中定义。
英文:
I have a Java 1.7 starts application. It does have some RESTful api's.
I would like to add @JsonIgnore to a filed so that it is not returned in the api.
E.g.
Member.java
import com.fasterxml.jackson.annotation.JsonIgnore;
private java.lang.String username;
@JsonIgnore
private java.lang.String password;
Does not ignore the password.
"member": {
"password": "**************",
"username": "richard"
}
I think the reason why @JsonIgnore does not work, is because I use com.fasterxml.jackson.annotation.JsonIgnore. Should I use a different annotation from a different library? i.e. Is my implementation of jaxrs maybe not com.fasterxml.jackson? How do I tell?
The IntelliJ classpath has:
(I have tried net.minidev.json.annotate.JsonIgnore with no success)
More info:
pom.xml
<dependency>
<groupId>net.minidev</groupId>
<artifactId>json-smart</artifactId>
<version>2.3</version>
</dependency>
and
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.11.2</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-annotations</artifactId>
<version>2.11.2</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.11.2</version>
</dependency>
Is this the problem? two versions! I am not sure where the 2.0.5 version comes from, as it is not defined in the pom.

你在这种情况下不需要使用 @JsonIgnore。你可以简单地省略你不想反序列化的变量（在这种情况下是密码），Jackson 将只返回用户名。
英文:
You don't need a @JsonIgnore in this case. You can simply omit the variable that you don't want deserialized(the password in this case) and jackson will just return you the username.
