java Jersey 2+Jackson注释/@JsonIgnore

Question

EDIT: Being more specific now i noticed a conflict i want to use BOTH dependencies below:

    <dependency>
        <groupId>org.glassfish.jersey.media</groupId>
        <artifactId>jersey-media-json-binding</artifactId>
        <version>2.27</version>
    </dependency>
    <dependency>
        <groupId>org.glassfish.jersey.media</groupId>
        <artifactId>jersey-media-json-jackson</artifactId>
        <version>2.3.1</version>
    </dependency>

基本上，我试图忽略一个属性（@JsonIgnore），但我的Jackson注释都不起作用。甚至@json属性。我试图在getter和setter方法中添加@JsonIgnore，但行为相同

我也试着遵循官方文件，尝试不同的图书馆

• 导入组织。科德豪斯。杰克逊。注释杰索尼诺；（同样的行为）
• 导入com。fasterxml。杰克逊。注释。杰索尼诺；（同样的行为）

我看到类似的帖子，比如#12595351

来自控制器的我的响应不应显示已撤销。属性，但我得到了以下响应：

Answer 1

以下代码适用于jackson版本2.8.10

import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

public class JsonIgnoreExample {
    private static class BeanWithIgnore {
        @JsonIgnore
        public int id;
        public String name;

        public BeanWithIgnore(int id, String name) {
            this.id = id;
            this.name = name;
        }
    }

    public static void main(String[] args) throws JsonProcessingException {
        BeanWithIgnore bean = new BeanWithIgnore(1, "My bean");
        String result = new ObjectMapper().writeValueAsString(bean);
        System.out.println(result); // {"name":"My bean"}
    }
}

Answer 2

选择以下任一项，但不能同时选择两项：

<!-- JSON-B (JSR-347) support -->
<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-binding</artifactId>
    <version>2.27</version>
</dependency>

<!-- Jackson 2.x support -->
<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-jackson</artifactId>
    <version>2.27</version>
</dependency>

Jackson和JSON-B都提供JSON-from/to-Java绑定：

• Jackson是一个非常成熟的JSON处理库。它很灵活，有相当数量的extensions modules

• JSON-B也被称为JSR-347。它是JSON绑定的规范。实际实现将由Eclipse Yasson提供，它是JSR-347的参考实现

---

如果你想使用^{}，你应该使用Jackson annotations。例如，要忽略属性，请使用^{}

如果您想使用^{}，那么应该使用JSON-B annotations。例如，要忽略属性，请使用^{}

---

您正在使用jersey-bom，这是一个依赖项管理工件，用于整合和集中依赖项版本的管理（而不实际将依赖项添加到项目中）

因此，您不需要指定org.glassfish.jersey工件的版本。使用以下选项之一（不带version）：

<!-- JSON-B (JSR-347) support -->
<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-binding</artifactId>
</dependency>

<!-- Jackson 2.x support -->
<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-json-jackson</artifactId>
</dependency>

更多详细信息请参见here和here

Answer 3

基本上，jersey-media-json绑定和jersey-media-json-jackson具有类似的行为。不能同时使用两者。jersey media json jackson无法工作的原因是，具有更高优先级的提供者是jersey media json绑定

Answer 4

这对我有用，我的pom中有这些LIB。xml:

        <dependency>
            <groupId>org.glassfish.jersey.media</groupId>
            <artifactId>jersey-media-json-jackson</artifactId>
            <version>${org.glassfish.jersey.core.version}</version>
            <scope>provided</scope>
        </dependency>


        <!-- ************** Jackson XML and JSON API ************************* -->          
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>${jackson-version}</version>
        </dependency>   

       <dependency>
            <groupId>org.glassfish.jersey.media</groupId>
            <artifactId>jersey-media-moxy</artifactId>
            <version>${org.glassfish.jersey.core.version}</version>             
            <scope>provided</scope>
        </dependency>

只需从类中删除该属性并添加此注释：

import com.fasterxml.jackson.annotation.JsonIgnoreProperties;

@JsonIgnoreProperties(ignoreUnknown=true)
public class Token {
// ... keep only the properties you want to map

这将告诉Jackson只绑定类中实际拥有的属性，忽略JSON输出中可能存在的所有其他属性

Answer 5

我不知道您项目的整个配置，所以我认为您可以这样做，即手动创建JSON，然后发送到响应，如：

ObjectMapper maper = new ObjectMapper();
return Response.ok(maper.writer().withDefaultPrettyPrinter().writeValueAsString(tokenObject));

它将像手动转换一样工作，而不使用Jersey的自动序列化
注意：这件事不推荐，但它应该会起作用

转换时需要此依赖项：

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version>2.2.3</version>
</dependency>
