Java Spring和Jackson ObjectMapper不使用自定义筛选器

我正在使用Spring3.2.1和Jackson 2

我有以下Spring配置文件：

<mvc:annotation-driven>
    <mvc:message-converters>
        <bean 
            class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">

            <property name="objectMapper" ref="myObjectMapper" />
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>
<bean
    name="myObjectMapper"
    class="org.me.reference.util.MyObjectMapper" />

我的域对象如下所示：

public class MyObjectMapper extends ObjectMapper {
    /**
     * A default version UID to use when serializing an instance of this class.
     */
    private static final long serialVersionUID = 1L;

    public MyObjectMapper() {
        setFilters(
            (new SimpleFilterProvider())
                .addFilter(
                    "CustomJacksonFilter",
                    SimpleBeanPropertyFilter.serializeAllExcept("password"));
    }
}

@JsonFilter("CustomJacksonFilter")
public class User {
    /**
     * The JSON key for the user's user-name.
     */
    public static final String JSON_KEY_USERNAME = "username";
    /**
     * The JSON key for the user's password.
     */
    public static final String JSON_KEY_PASSWORD = "password";

    /**
     * The user's user-name.
     */
    @JsonProperty(JSON_KEY_USERNAME)
    private final String username;
    /**
     * The user's password.
     */
    @JsonProperty(JSON_KEY_PASSWORD)
    private final String password;

    ...
}

基本上，我希望确保在返回用户对象时不会自动序列化密码。我觉得这应该是可行的，但是我得到了以下错误：

Caused by: com.fasterxml.jackson.databind.JsonMappingException: Can not resolve BeanPropertyFilter with id 'CustomJacksonFilter'; no FilterProvider configured

我尝试了上述配置的许多变体，但都没有成功。我已经研究过如何使用视图，但是我需要注释所有内容，除了我不想序列化的一个字段，它太麻烦了

任何建议都将不胜感激。谢谢,

约翰

您的

ObjectMapper

实现工作正常，并提供了一个

FilterProvider

，但查看异常的堆栈跟踪，它看起来不像是为序列化调用您注册的

MappingJackson2HttpMessageConverter

。因此，您必须使用不同的

ObjectMapper

来序列化。请看下面的两个答案：谢谢，但它们似乎不起作用。我尝试了

过滤器provider.setFailOnUnknownId（false），这似乎很有希望，但似乎不起作用。至于获取写入程序，我将所有这些留给Spring。请发布完整堆栈跟踪。添加完整堆栈跟踪。我想我现在明白问题所在了。MongoJack FilterProvider不需要在未知ID上失败。我只是自己尝试了
ObjectMapper
，它适合我。我建议您通过在
映射Jackson2HttpMessageConverter
中放置断点进行调试。似乎它正在使用另一个映射程序。是MongoJack ObjectMapper在数据库端执行（反）序列化，而不是HTTP端。谢谢
